The image data to be searched is, for example, image data leaked in the log information management system 100. In the log information management apparatus 110, the search target acquisition unit 115 acquires image data to be searched, and the processing unit 111 processes the image data to generate search condition information to be a search condition. Then, the search unit 116 searches the storage unit 117 based on the search condition information.

The search condition information in the search processing by 116 is generated.

  The area setting unit 112 sets an area for each data constituting the image data for the image data acquired from the log information collection device 120. For example, when the image data is A4 size image data, the area setting unit 112 identifies the component data constituting the image data from the upper left to the lower right, and sets the area based on the identification result. To do. Details of the area setting process will be described later.

Details of the storage process in the storage unit 117 will be described later. The control unit 118 controls each process executed in the log information management apparatus 110.

  The log information collection device 120 is realized by, for example, a computer having a CPU and a memory as an arithmetic processing device. The log information collection device 120 is connected to the image forming device 121. The log information collection device 120 includes, for example, a database 123, and stores the image log information transmitted from the image forming device 121 in the database 123. Here, the database 123 may be connected to the outside of the computer that implements the log information collection device 120 by an appropriate method, or may be a hard disk drive provided inside the computer that implements the log information collection device 120. It may be.

  The image forming apparatus 121 is, for example, a printer or the like, receives image data (print data) created by the print request terminal 122, prints the image data, and print logs that are print history of the image data. Is generated. Then, the image data and the print log are transmitted to the log information collection device 120 as image log information. The image forming apparatus 121 only needs to have a print function, and may be a color printer, a multifunction peripheral, a monochrome printer, or the like.

  The print request terminal 122 is, for example, a computer having an input device and a display device. In the print request terminal 122, in addition to a print instruction to the image forming apparatus 121, image data is created by the user. The image data created in the print request terminal 122 is transmitted to the image forming apparatus 121 together with a print instruction, and is output by printing processing in the image forming apparatus 121.

  Here, with reference to FIG. 2 and FIG. 3, specific examples of the region setting by the region setting unit 112 and the region identification information extracted by the extraction unit 113 will be described.

  FIG. 2 is a first diagram illustrating region setting and region identification information in the first embodiment. For example, it is assumed that the database 123 of the log information collection device 120 stores the image data 250 illustrated in FIG. 2 and the operation history information related to the image data 250. The example illustrated in FIG. 2 shows a case where an area is set for each type of data constituting image data.

  The image data 250 includes a text part 251 and an image part 252.

  When the log information management device 300 acquires the image data from the storage device 220, the log information management device 300 recognizes a group of data constituting the image data from the upper left to the lower right of the image data 250. In the case of the image data 250, the text portion 251 is recognized first, and then the image portion 252 is recognized. Here, in the present embodiment, the text portion 251 is the region 1 and the image portion 252 is the region 2.

  In the present embodiment, the area setting unit 112 of the present embodiment may set the areas in the order in which the data types are recognized in the image data 250. That is, in this embodiment, the area setting unit 112 recognizes the text part 251 first, and then recognizes the image part 252. Therefore, in this embodiment, the area setting unit 112 sets the text part 251 as the area 1 and the image part 252 as the area 2.

  When the region is set by the region setting unit 112, the region identification information for each region is extracted by the extraction unit 113. The extraction unit 113 of the present embodiment extracts region identification information 251F for region 1 and region identification information 252F for region 2.

  The area identification information will be specifically described below. The area identification information includes area information indicating the position of the area in the image data and type information indicating the type of image data in the area.

  The area information is information indicating the coordinate information of a point serving as a reference of the area and the size of the area. This indicates the position of the region in the image data. For example, the area information of the area 1 in the image data 250 is the coordinates and size in the area identification information 251F. Here, the coordinate information in the present embodiment indicates, for example, the coordinates of the upper left point A of the area 1 when the upper left point of the image data 250 is the origin. Further, the information indicating the size in the present embodiment indicates the height and width of the region 1. Thereby, the position of the region 1 in the image data 250 can be indicated.

  The type information indicates the type of image data in the area, and there are four types of image data in this embodiment: color image, monochrome image, text, and table. In the present embodiment, the type corresponding to the image data in the area is the type information. That is, since the image data in the area 1 of the present embodiment is text data, the type information of the area identification information 251F is text.

  Further, when the type information of the area identification information is text, the OCR unit 114 may recognize the text data in this area and add the number of characters and the content of the text data to the area identification information. In this embodiment, since the type information of area 1 is text, character information is added to area identification information 251F of area 1.

  Similarly to the area 1, the area identification information 252F is extracted for the area 2. Among the area information of the area 2, the coordinate information indicates the coordinates of the upper left point B of the area 2 when the upper left point of the image data 250 is the origin. The information indicating the size in the present embodiment indicates the height and width of the region 2. Thereby, the position of the area 2 in the image data 250 can be indicated. Since the type information of the region 2 is the color image of the image data of the region 2, the type information of the region 2 is a color image.

  Next, with reference to FIG. 3, the case where a region is set based on the arrangement of data constituting image data will be described. FIG. 3 is a second diagram illustrating region setting and region identification information in the first embodiment.

  The image data 380 includes a text part 381, a text part 382, a color image part 383, and a color image part 384. In the example illustrated in FIG. 3, the region setting unit 112 sets a region with the margin as a boundary when there is a margin of a predetermined width or more between the respective parts constituting the image data 380.

  The area setting unit 112 recognizes data constituting the image data 380 from the upper left to the lower right of the image data 380. In the example illustrated in FIG. 3, the area setting unit 112 recognizes a text part 381, a text part 382, an image part 383, and an image part 384 in this order. Here, since the area setting unit 112 recognizes that the margin part 381A between the text part 381 and the text part 382 has a predetermined width or more, the data types of the text part 381 and the text part 382 are the same text. Also set each to a different area.

  Similarly, in the image part 383 and the image part 384, the area setting unit 112 recognizes that the margin part 383A is equal to or larger than the predetermined width, and therefore can set each of them in a different area.

  In the area setting unit 112 of this embodiment, an area is set by a method that combines the area setting methods described with reference to FIGS. That is, the area setting unit 112 according to the present embodiment sets an area for image data based on the type of data constituting the image data and the arrangement of the data.

  Next, the operation of the log information management system 100 of this embodiment will be described.

  Here, the log information management system 100 of the present invention is intended to efficiently acquire target information from information to be managed. Therefore, a characteristic operation of the log information management system 100 of the present invention is an operation of searching for specific image log information from the image log information stored in the log information management apparatus 110.

  Therefore, prior to description of search processing in the log information management system 100 of the present embodiment, storage processing in the log information management apparatus 110, which is a premise of this search processing, will be described. FIG. 4 is an example of a flowchart for explaining storage processing in the log information management apparatus 110 according to the first embodiment.

  The log information management device 110 collects the image log information collected by the log information collection device 120 and stores it in the storage unit 117. At this time, the log information management apparatus 110 acquires image data included in the image log information (S41). When the log information management apparatus 110 acquires image data, the processing unit 111 processes the image data.

  The processing unit 111 recognizes data constituting the acquired image data (S42), and sets an area for the recognized data by the area setting unit 112 (S43). In the processing unit 111, when the region is set, the extraction unit 113 extracts region identification information for each region (S44). The processing unit 111 performs the processes of S43 and S44 for each data recognized in S42.

  Then, the control unit 118 associates the region identification information with the corresponding image log information as the search condition information, and stores it in the storage unit 117 (S45). Hereinafter, in the description of the present embodiment, region identification information and search condition information are synonymous.

  As described above, in the log information management device 110, the storage unit 117 stores the image log information and the search condition information generated from the characteristic portion of the image data included in the image log information in association with each other. For example, FIG. 5 shows an example of search condition information associated with image log information stored in the storage unit 117.

  For this reason, for example, when image data printed out in this embodiment is leaked, search condition information indicating the characteristics of the leaked image data is generated for the leaked image data by the processing in the storage process, and the search condition What is necessary is just to search the storage part 117 by information. In this way, the storage unit 117 can efficiently acquire image log information including image data whose characteristics match that of the leaked image data, and can quickly grasp the outflow route of the leaked image data.

  Here, the image data search process in the present embodiment will be described below.

  FIG. 6 is an example of a flowchart for explaining a first pattern of search processing in the log information management system 100 of the first embodiment.

  In the example shown in FIG. 6, the region identification information of the image data to be searched is set as search condition information, and the storage unit 117 performs a search using this region identification information. Here, the leaked image data may be, for example, image data that has been printed once and leaked in the form of a paper document. In this case, image data obtained by scanning the paper document by the image forming apparatus 121 becomes leaked image data, and the leaked image data is once collected by the log information collecting device 120.

  In the log information management apparatus 110, for example, when an administrator of the log information management system 100 gives an instruction to execute a search process, the log information management apparatus 110 is a search target from the log information collection apparatus 120 by the search target acquisition unit 115. Leakage image data is acquired (S61). Next, the log information management apparatus 110 sets a region for the acquired leaked image data by the region setting unit 112 of the processing unit 111, and acquires the type information of this region by the extraction unit 113 (S62). When the type information is acquired from the leaked image data in S62, the search unit 116 searches the region identification information including the same type information as the type information in the storage unit 117 (S63).

  Next, the log information management device 110 uses the extraction unit 113 to extract region information of the region set in the leaked image data (S64). The retrieval unit 116 retrieves region identification information including the same region information as the region information from the region identification information retrieved in S63 (S65). The log information management apparatus 110 performs the processing from S62 to S65 on the leaked image data for all the areas set in the leaked image data.

  By performing the search process in this way, it is possible to search for image log information having the same type information and area information in all areas set in the leaked image data. That is, it is possible to search for image log information including image data having the same characteristics as the leaked image data. The log information management apparatus 110 determines the image log information as a result of the search process (S66). Here, the log information management apparatus 110 may include a display device (not shown), and the search result determined in S66 is preferably displayed on this display device.

  Here, when searching the storage unit 117 with the area information in S65, the search process may be performed with a slight error as an allowable range. As described above, if the search process is performed in consideration of the error, even if there is a slight difference rather than a complete match, the search result is reflected in the search result, so that the search process can be performed in a wider range.

  The error here may be, for example, an error of coordinate information in the area information. This coordinate information is the coordinates of the reference point in the region. The error may be, for example, an error in information indicating the width and height of the area in the area information. The error may be, for example, a percentage representing the degree of deviation between the arrangement of the areas in the leaked image data to be searched and the arrangement of the areas in the image data stored in the storage unit 117.

  In the present embodiment, a certainty factor indicating the reliability of the search result (the probability that the search result is correct) may be given to the search result of the search process including this error based on the magnitude of the error. For example, when the error is small, the certainty factor is high, and when the error is large, the certainty factor is low. For example, when a plurality of search results are obtained, the certainty factor may be indicated by giving a ranking to each search result in ascending order of error.

  FIG. 7 is an example of a flowchart for explaining a second pattern of search processing in the log information management system 100 of the first embodiment.

  In the example illustrated in FIG. 7, the above-described certainty factor is given to the search processing result described in FIG. 6. The processing from S71 to S75 in FIG. 7 is the same as the processing from S61 to S65 in FIG. When the search processing result is obtained in S75, the log information management apparatus 110 calculates an error between the leaked image data to be searched and the image data of the search result (S76).

  The log information management apparatus 110 performs the processes from S71 to S76 as many times as the number of areas set in the leaked image data. Then, the log information management device 110 gives a certainty factor to the image data of the search processing result (S77), and confirms the search processing result based on the certainty factor (S78). Here, as a result of the search process, for example, when the certainty factor is given by rank, the search process result with the highest rank may be determined in S78. Moreover, it is preferable that the log information management device 110 displays the determination result on the display device.

  Next, another pattern of the search process of this embodiment will be described with reference to FIG. FIG. 8 is an example of a flowchart for explaining a third pattern of search processing in the log information management system 100 of the first embodiment.

  In the example illustrated in FIG. 8, the search unit 116 searches the storage unit 117 using the appearance order of each region in the leaked image data as search condition information.

  In the log information management device 110, when the search target acquisition unit 115 acquires leaked image data to be searched from the log information collection device 120 (S81), the processing unit 111 acquires area identification information of the leaked image data (S82). . At this time, the processing unit 111 assigns information indicating the order in which the areas are set to the leaked image data, that is, the appearance order information of the areas to the area identification information (S83).

  The processing unit 111 uses the appearance order of the regions and the type information of the regions as search condition information, and the search unit 116 searches the storage unit 117 based on the search condition information. When the search process of the search unit 116 in S83 ends, the log information management apparatus 110 determines this result (S84). The log information management device 110 preferably displays the determination result on the display device.

  The search condition information here will be described with a specific example. For example, it is assumed that the leaked image data is the image data 250 shown in FIG. In this case, the first appearing area is area 1, and the type information of area 1 is text. In the image data 250, the area 2 appears next, and the type information of the area 2 is a color image. Therefore, the appearance order information of the area here is (rank 1-text, rank 2-color image), and this is search condition information. When the search process shown in FIG. 8 is performed, it is preferable that the appearance condition information of the region is given to the search condition information stored together with the image log information in the storage unit 117.

  Next, another pattern of the search process of this embodiment will be described with reference to FIG. FIG. 9 is an example of a flowchart illustrating a fourth pattern of search processing in the log information management system 100 of the first embodiment.

  In the example illustrated in FIG. 9, the search unit 116 searches the storage unit 117 using the appearance count for each data type of each area in the leaked image data as search condition information.

  The processing in S91 and S92 in FIG. 9 is the same as S81 and S82 in FIG. When acquiring the region identification information in S92, the processing unit 111 counts and acquires the number of appearances for each type based on the region type information, and adds the appearance number information indicating the number of appearances to the region identification information (S93). .

  Then, the processing unit 111 uses the appearance count information for each data type in this area as search condition information, and the search unit 116 searches the storage unit 117 based on the search condition information. When the search process of the search unit 116 in S93 ends, the log information management apparatus 110 determines this result (S94). The log information management device 110 preferably displays the determination result on the display device.

  The search condition information here will be described with a specific example. For example, it is assumed that the leaked image data is the image data 380 shown in FIG. In this case, the type information in the area identification information of the areas 381 and 382 is text, and the type information in the area identification information of the areas 383 and 384 is a color image. Therefore, the number of appearances of the area for each data type here is (text-2, color image-2), which is the search condition information. When the search process shown in FIG. 9 is performed, it is preferable that the search condition information stored together with the image log information in the storage unit 117 is given the appearance frequency information for each data type of the area.

  Next, another pattern of the search process of this embodiment will be described with reference to FIG. FIG. 10 is an example of a flowchart for explaining the fifth pattern of search processing in the log information management system 100 of the first embodiment.

  In the example shown in FIG. 10, when the data type of the area set in the leaked image data is a table, the search unit 116 searches the storage unit 117 using the configuration of this table as search condition information.

  The processing in S101 and S102 in FIG. 10 is the same as the processing in S81 and S82 in FIG. The processing unit 111 determines whether or not the type information of the area identification information acquired in S102 is a table. If the type information is a table (S103), the processing unit 111 indicates the number of rows and columns indicating the number of rows and columns in this table. Column number information is acquired (S104).

  Then, the search unit 116 searches the storage unit 117 using the row / column number information as search condition information (S105). The log information management apparatus 110 repeats the processing from S102 to S105 as many times as the number of areas set in the leaked image data. Then, when the search process of the search unit 116 in S105 ends, the log information management apparatus 110 determines this result (S106). The log information management device 110 preferably displays the determination result on the display device.

  Here, when the log information management apparatus 110 performs the search process shown in FIG. 10, if the search condition information stored together with the image log information in the storage unit 117 is a table of area type information, It is preferable that table row / column number information is given.

  Next, another pattern of the search processing of this embodiment will be described with reference to FIG. FIG. 11 is an example of a flowchart for explaining the sixth pattern of search processing in the log information management system 100 of the first embodiment.

  In the example shown in FIG. 11, when the data type of the area set in the leaked image data is a color image, the search unit 116 searches the storage unit 117 using the color information of this color image as search condition information.

  In the log information management device 110, when the search target acquisition unit 115 acquires leaked image data to be searched from the log information collection device 120 (S111), the processing unit 111 sets an area for the leaked image data, and region identification information Is acquired (S112).

  The processing unit 111 determines whether or not the type information of the area identification information acquired in S112 is a color image (S113). If the type information is a color image, the processing unit 111 acquires color information of this color image (S114). Then, the search unit 116 searches the storage unit 117 using this color information as search condition information (S115). The log information management apparatus 110 repeats the processing from S112 to S115 as many times as the number of areas set in the leaked image data. Then, when the search processing of the search unit 116 in S115 ends, the log information management apparatus 110 determines this result (S116). The log information management device 110 preferably displays the determination result on the display device.

  At this time, the color information serving as the search condition information may be color information expressed in RGB format, for example. When the log information management apparatus 110 performs the search process shown in FIG. 11, the search condition information stored together with the image log information in the storage unit 117 includes this area when the area type information is a color image. It is preferable that the color information is given.

  Next, another pattern of the search process of this embodiment will be described with reference to FIG. FIG. 12 is an example of a flowchart for explaining a seventh pattern of search processing in the log information management system 100 of the first embodiment.

  In the example shown in FIG. 12, the processing unit 111 divides the leaked image data into a predetermined number of blocks separately from the region set by the region setting unit 112 for the leaked image data, and the arrangement of the regions in this block Get information. The search unit 116 searches the storage unit 117 using the area arrangement information in this block as search condition information.

  In the log information management device 110, when the search target acquisition unit 115 acquires leaked image data to be searched from the log information collection device 120 (S121), the processing unit 111 divides the leaked image data into a predetermined number of blocks ( S122). Returning to FIG. 2, the division of the leaked image data will be described with reference to FIG. The image data 250 shown in FIG. 2 is assumed to be leaked image data. In the example of the search process illustrated in FIG. 12, the processing unit 111 divides the image data 250 into four blocks 260, 261, 262, and 263.

  Next, the processing unit 111 sets an area in the leaked image data and acquires area identification information (S123). When acquiring the region identification information, the processing unit 111 acquires block information that is information indicating the arrangement of the regions in each block (S124).

  Here, returning to FIG. 2 again, the block information will be specifically described. In the image data 250 shown in FIG. 2, since the area 1 is arranged across the blocks 260, 261, and 262, the block information of the area 1 is, for example, (1-260, 261, 262). Also. Since the area 2 is arranged across the block 261 and the block 263, the block information of the area 2 is, for example, (2-261, 263).

  The log information management apparatus 110 uses this block information as search condition information. Then, the search unit 116 searches the storage unit 117 using this block information as search condition information. The log information management apparatus 110 repeats the processes of S123 and S124 as many times as the number of areas set in the leaked image data. Then, when the search process of the search unit 116 ends, the log information management apparatus 110 determines this result (S125). The log information management device 110 preferably displays the determination result on the display device.

  In this embodiment, the leaked image data is divided into four blocks. However, the number of blocks is not limited to this, and the log information management device 110 can be arbitrarily set by setting means (not shown). May be. Furthermore, when the log information management apparatus 110 performs the search process shown in FIG. 12, it is preferable that block information is added to the search condition information stored together with the image log information in the storage unit 117. In addition, the block information of the leaked image data at this time is preferably based on the divided blocks in the same manner as the image data stored in the storage unit 117.

  Next, another pattern of the search process according to this embodiment will be described with reference to FIG. FIG. 13 is an example of a flowchart for explaining the eighth pattern of search processing in the log information management system 100 of the first embodiment.

  In the example illustrated in FIG. 13, when the type information of the area set in the leaked image data is text, the number of characters in the area is detected by the OCR unit included in the processing unit 111, and the search unit 116 indicates information indicating this number of characters. Is stored as search condition information.

  In the log information management device 110, when the search target acquisition unit 115 acquires leaked image data to be searched from the log information collection device 120 (S131), the processing unit 111 sets an area for the leaked image data, and region identification information Is acquired (S132). When obtaining the region identification information, the processing unit 111 determines whether or not the region type information is text (S133). If the type information is text, the OCR unit 114 causes the OCR unit 114 to indicate the number of characters in the region. Information is acquired (S134).

  Then, the search unit 116 searches the storage unit 117 using the character number information as search condition information (S135). The log information management apparatus 110 repeats the processing from S132 to S135 as many times as the number of areas set in the leaked image data. Then, when the search processing of the search unit 116 in S135 ends, the log information management apparatus 110 determines this result (S136). The log information management device 110 preferably displays the determination result on the display device.

  Here, when the log information management apparatus 110 performs the search processing shown in FIG. 13, the search condition information stored together with the image log information in the storage unit 117 includes this type of information when the region type information is text. It is preferable that information on the number of characters in the area is given.

  Next, another pattern of the search process of this embodiment will be described with reference to FIG. FIG. 14 is an example of a flowchart for explaining the ninth pattern of search processing in the log information management system 100 of the first embodiment.

  In the example shown in FIG. 14, when the type information of the area set in the leaked image data is text, the OCR unit included in the processing unit 111 detects the number of lines in the area, and the search unit 116 determines the number of lines. The storage unit 117 is searched using the indicated line number information as search condition information.

  The processing from S141 to S143 in FIG. 14 is the same as the processing from S131 to S133 in FIG. When the type information of the area is text in S143, the processing unit 111 acquires line number information indicating the number of lines in the area by the OCR unit 114 (S144).

  Then, the search unit 116 searches the storage unit 117 using the line number information as search condition information (S145). The log information management apparatus 110 repeats the processing from S142 to S145 as many times as the number of areas set in the leaked image data. Then, when the search processing of the search unit 116 in S145 ends, the log information management apparatus 110 determines this result (S146). The log information management device 110 preferably displays the determination result on the display device.

  Here, when the log information management apparatus 110 performs the search process shown in FIG. 14, the search condition information stored together with the image log information in the storage unit 117 includes this information when the region type information is text. Information on the number of lines in the region is preferably given.

  Next, another pattern of the search process according to this embodiment will be described with reference to FIG. FIG. 15 is an example of a flowchart illustrating a tenth pattern of search processing in the log information management system 100 of the first embodiment.

  In the example shown in FIG. 15, when the type information of the region set in the leaked image data is text, the OCR unit included in the processing unit 111 detects the number of appearances of a specific word in the region, and the search unit 116 The storage unit 117 is searched using the appearance number information indicating the number of appearances as search condition information.

  The processing from S151 to S153 in FIG. 15 is the same as the processing from S131 to S133 in FIG. When the region type information is text in S153, the processing unit 111 searches for a specific word in the region by the OCR unit 114 (S154), counts the number of appearances of the specific word, and displays the appearance number information. Obtain (S155).

  Then, the search unit 116 searches the storage unit 117 using the appearance number information as search condition information. The log information management apparatus 110 repeats the processing from S152 to S155 as many times as the number of areas set in the leaked image data. Then, when the search processing of the search unit 116 in S155 ends, the log information management apparatus 110 determines this result (S156). The log information management device 110 preferably displays the determination result on the display device.

  Here, the specific word may be set in advance by the administrator as a setting condition of the log information management device 110, or may be set each time the search process shown in FIG. 15 is performed. In the example illustrated in FIG. 15, by setting a specific word, it is possible to perform a search process suitable for the usage environment of the log information management system 100. For example, when the image forming apparatus 121 is arranged in a personnel department of a company, a word related to personnel changes may be set as a specific word. In this case, for example, when information related to personnel changes leaks, the storage unit 117 can be searched with the set word. Therefore, the system administrator can acquire target information more quickly.

  Here, when the log information management apparatus 110 performs the search process shown in FIG. 15, the search condition information stored together with the image log information in the storage unit 117 includes this information when the region type information is text. It is preferable that appearance frequency information of a specific word is given in the area.

  Next, another pattern of the search process of this embodiment will be described with reference to FIG. FIG. 16 is an example of a flowchart for explaining the eleventh pattern of search processing in the log information management system 100 of the first embodiment.

  In the example illustrated in FIG. 16, the OCR unit included in the processing unit 111 detects the number of times a specific word appears in the leaked image data, and the search unit 116 stores the appearance number information indicating the number of appearances as search condition information. 117 is searched. In the search process illustrated in FIG. 16, the processing unit 111 performs only the OCR process by the OCR unit 114 without setting the area and acquiring the area identification information for the leaked image data. Therefore, the search process shown in FIG. 16 is preferably used when, for example, the leaked image data is document data including only text data.

  The log information management apparatus 110 uses the search target acquisition unit 115 to acquire leaked image data to be searched from the log information collection apparatus 120 (S161). When the processing unit 111 acquires leaked image data, the OCR unit 114 executes OCR processing to search for a specific word (S162). Then, the processing unit 111 counts and detects the number of appearances of a specific word in the leaked image data (S163).

  The search unit 116 searches the storage unit 117 using the appearance number information as search condition information, and finalizes the search result when the search process ends (S164). The log information management device 110 preferably displays the determination result on the display device.

  The specific word here is the same as that described in the example shown in FIG. 15, and may be set in advance by the administrator as a setting condition of the log information management apparatus 110, as shown in FIG. It may be set each time the search process is performed. When the log information management apparatus 110 performs the search process shown in FIG. 16, the search condition information stored together with the image log information in the storage unit 117 is given information about the number of appearances of a specific word in the image data. It is preferable.

  The search processing pattern in the log information management system 100 of this embodiment has been described above. As can be seen from the description of each pattern, the log information management apparatus 110 according to the present embodiment includes a search prescription formula using the OCR function by the OCR unit 114 and a search method not using the OCR function. A search method using the OCR function is based on text data. Therefore, this search method is preferable mainly when the data constituting the leaked image data is text data or contains a lot of text data. A search method that does not use the OCR function is based on region characteristics such as region appearance rank, number of appearances, arrangement information, and color information. Therefore, this search method is preferable when the data constituting the leaked image data is other than text data.

  Therefore, in the present embodiment, when searching for leaked image data, a search method suitable for the leaked image data that is the search target may be selected. FIG. 17 is an example of a flowchart illustrating selection of a search method in the first embodiment.

  The log information collection apparatus 110 according to the present embodiment includes a selection unit (not shown). Even when the administrator of the log information management system 100 performs a search process for leaked image data, the selection unit selects a search method. Good (S171). When the search method is selected, the log information collection device 110 performs search processing according to this search method (S172), and finalizes the search result (S173).

  In S171, the administrator of the log information management system 100 may select an OCR search method using the OCR function when, for example, the leaked image data is only text data. If the leaked image data is image data or the like, a search method other than the OCR function search method may be selected.

  Here, the log information management device 110 may be realized by a general computer or the like having a display as a display device and a keyboard as an input device. It may be realized by a mouse or the like.

  In the log information collection management apparatus 110 according to the present embodiment, in the search method that does not use the OCR function, for example, when the type information is a table, the search method based on the table row / column number information is a search method suitable for this. May be selectable (see FIG. 10). Similarly, in the log information management device 110, for example, when the type information is a color image, a search method using color information suitable for this may be selectable (see FIG. 11). Further, in the log information management apparatus 110, for example, when a large number of areas having different type information appear in leaked image data, a search method based on the appearance order information of the areas or the appearance frequency information may be selectable (FIG. 8). FIG. 9).

  In this way, by selecting a search method suitable for the characteristics of the region set in the leaked image data in the log information management apparatus 110, target information can be acquired more quickly from the information to be managed. .

  In the log information management apparatus 110 of this embodiment, the search method described with reference to FIG. 17 may be automatically selected. FIG. 18 is an example of a flowchart illustrating search method selection processing in the log information management apparatus 110 according to the first embodiment.

  In the log information management device 110, when the search target acquisition unit 115 acquires the leaked image data that is the search target from the log information collection device 120 (S181), the control unit 118 of the area set in the acquired leaked image data. The characteristic is identified (S182). The region characteristics here may be, for example, the data type in the region, the number of appearances of the region, the appearance order, etc., as described above.

  When the control unit 118 identifies the characteristics of the region set in the leaked image data, the control unit 118 selects a search method that matches the characteristics. When the search method is selected, the processing unit 111 generates search condition information by this search method. Then, the search unit 116 searches the storage unit 117 based on the search condition information (S183). When the search process of the search unit 116 is completed, the log information management apparatus 110 determines this process result (S184).

  Furthermore, in the log information management apparatus 110 of this embodiment, the search method may be automatically changed according to the search processing result. FIG. 19 is an example of a flowchart illustrating search method selection processing based on search processing results in the log information management apparatus 110 according to the first embodiment.

  When the log information management apparatus 110 performs a search process using the search method selected by the search unit 116 (S191), the control unit 118 calculates the degree of coincidence of the search results. Here, the degree of coincidence represents, for example, the degree of coincidence between the area set in the image data obtained as a search result and the area set in the leaked image data to be searched as a percentage. Also good.

  Then, the control unit 118 determines whether or not the calculated degree of coincidence is equal to or less than a predetermined value (S192). The predetermined value at this time may be set at the time of initial setting of the log information management apparatus 110, or may be set every time when the search process is performed.

  In S192, when the degree of coincidence is equal to or greater than the predetermined value, the log information management apparatus 110 determines the search result (S193) and ends the search process. When the degree of coincidence is smaller than the predetermined value in S192, the control unit 118 performs a search process using another search method (S194). In S194, for example, the processing from S182 to S183 in FIG. 18 may be executed.

  As described above, in the log information management system 100 according to the present embodiment, a search process result with higher accuracy can be obtained by using only image data having a predetermined matching degree or more as a search result.

  As described above, according to the log information management system 100 of this embodiment, target information can be quickly acquired from information to be managed.

In this embodiment, the log information management apparatus 110 that manages image log information and searches for leaked image data and the log information collection apparatus 120 that collects image log information from the image forming apparatus 121 are provided separately. It is possible to search for leaked image data without stopping collecting image log information generated by the image forming apparatus 121 as needed. Therefore, in the log information management system 100 of this embodiment, even when information leakage occurs, it is possible to quickly identify the leaked information without grasping the normal operation of the system, and to grasp the information outflow route. it can.
(Second embodiment)
A second embodiment of the present invention will be described below with reference to the drawings. FIG. 20 is a system configuration diagram of a log information management system 110A according to the second embodiment of this invention.
