Description

Specification

Protect file creation system, Protect file creation program, and technical field

[0001] The present invention relates to a protected file creation system and a protected file creation program for creating a protected file in which a target file, such as an application program in an executable format, is protected such as startup restrictions. The present invention also relates to a protection method for restricting activation of an application program.

Background art

[0002] Executable files such as application programs used on computers basically have the property that they can be used on any computer of the same type. Moreover, such an execution final can be easily copied by a computer. For this reason, the executable file may be used unintentionally by the file provider (application program developer), such as being used on a computer other than the assumed computer or illegally copied. There is.

[0003] As a method for preventing such unintended use, a unique ID is stored in the medium storing the data that has been registered, and the terminal (computer) accessing the medium corresponds to the unique ID. A security protection system has been proposed in which the terminal ID is stored, and access to the medium is permitted only when the correspondence between the unique ID and the terminal ID matches (that is, the encrypted data can be read). (See Patent Document 1). As a result, the security protection system is supposed to make it impossible to read encrypted data by another terminal even if the medium is transferred to another person.

Problems to be solved by the invention

[0004] By the way, a large number of application programs that can be used in a computer are stored in a medium such as a CD-ROM and sold. Also, freeware and shareware CDs that include application programs attached to magazines and computer-related magazines—

There are many application programs that are provided in ROM and DVD—ROM, and in download form via the Internet.

[0005] Among these application programs, those that prevent the unintended use of application programs by developers such as unauthorized copying, etc. are appropriately protected, such as the above-described protection of access by the unique ID and terminal ID. Is applied.

[0006] This protection is realized by an application program developer who independently develops a protection module, which is incorporated into the source code of the application program and compiled.

[0007] However, such protection has a problem that a burden imposed on the developer is large, for example, knowledge different from that for developing the original application program is required.

[0008] In addition, when a protect module is incorporated in the source code of an application program, a bug may occur due to this incorporation. For this reason, the problem of protection was that the development period was prolonged and the development cost increased to eliminate bugs.

[0009] The above-mentioned security protection system cannot solve such problems.

In view of the above problems, an object of the present invention is to provide a profile creation program for an execution file of an application program. Another object of the present invention is to provide a protection method capable of preventing unauthorized use of an application program.

When the present invention is implemented, protection is easily applied to a target file to be protected. I can do it. In addition, since a protect program is attached to the target file, it is not necessary to rewrite the program contents of the target file itself in order to protect it. Therefore, it is possible to improve the completeness of a protected target file that does not cause bugs to be mixed into the target file.

Here, the protect program is protected data corresponding to the type of protection (for example,

User ID and password, number of uses, number of days used, expiration date, serial number unique to the computer, etc.).

[0013] The protect file creation system of the present invention includes a protect content specifying unit that allows specification of protect content, and the protect program is configured to execute protection of the specified protect content.

When the present invention is implemented, the developer of the target file can apply a desired type of protection to the target file.

[0015] The protected file creation system of the present invention executes the protect program when the protected file is activated, determines whether the protected file is activated, and activates the target file when it is determined that activation is possible. The structure to do.

That is, the protected file creation system is configured to execute a protect program before starting the target file to determine whether the target file can be started, and to start the target file when it is determined that the target file can be started. It has a protect file.

[0017] Thus, before the target file is executed, the protect program is executed to determine whether the target file can be activated. Therefore, it is possible to reliably protect the target file without changing the program content of the target file.

[0018] Further, the present invention provides a target file designation process in which a target file to be protected is designated and permitted by the target file designation means, the target file generation process by the protect file generation means, and an output means for the generated protected file. This is a protected file creation program that causes a computer to execute the output process that is output by.

In the protect file creation program of the present invention, a protect program is added to the target file. Before executing the target file, make sure that the protect program is A protect file is configured to be executed. As a result, bugs are not mixed in the target file, and the target file can be reliably protected.

[0020] In the application program protection method of the present invention, a protection program that is executed before the application program is started is assigned to the application program.

In the present invention, a protect program is added to the application program. As a result, the protected program is given without changing the program contents of the application program. Therefore, bugs cannot be mixed into the application program. Since the protect program is executed before the application program is started, the protect program can be reliably protected.

[0022] The present invention is a method for protecting an application program, wherein the protection program releases the protection when a predetermined condition is satisfied, and the application program can be started when the protection is released.

[0023] The protection method of the application program of the present invention releases the protection when the predetermined condition for the protection program is satisfied, and the protection program can be activated when the protection is released. The application program cannot be started before it is released. Therefore, when the present invention is implemented, unauthorized use of the application program can be prevented.

[0024] In the application program protecting method of the present invention, the predetermined condition is predetermined data related to a regular license.

By implementing the present invention, it is possible to prevent unauthorized use of the application program by a person other than the authorized license owner who can know the predetermined condition.

[0026] The present invention provides an application that releases protection when there is an input that matches the predetermined data.

By implementing the present invention, the authorized license holder can reliably release the protection by inputting predetermined data, and can activate the protected application program. The invention's effect

[0028] According to the present invention, it is possible to provide a protected file creation system and a protected file creation program that can easily protect a file.

In the application program protecting method according to the present invention, since the protect program is assigned to the application program, there is no need to change the application program. Therefore, it is possible to avoid the occurrence of bugs in application programs. In addition, since the protection program is executed before the application program is started, unauthorized use can be surely prevented.

FIG. 5 shows a flowchart of operations executed by the control device 6 in accordance with the protect file creation program 20.

[0060] When the protect file creation program 20 is activated by the operation of the input device 2 by the user (developer of the target application 11, etc.), the control device 6 displays the protect condition setting screen 30 (see FIG. 2). The information is displayed on the display device 3 (step S 1).

[0061] The target application 1 is displayed on the protection condition setting screen 30 by the operation of the input device 2 by the user.

When 1 is selected (step S2), the control device 6 takes the selected target application 11 into the RAM (step S3).

[0062] The control device 6 generates a protect file 21 having the protect data 22 (see Fig. 1) storing the protect contents set in step S1 and the target application 11 captured in step S3 ( Step S4).

[0063] When the protect file 21 is activated, the protect file 21 determines whether or not activation is possible according to the contents of protection stored in the protection data 22. If the activation is determined to be possible, the target application 11 is activated. Format program. For this reason, the compiled executable application 11 is imported without any change.

[0064] By capturing in this way, the end user cannot directly start the target application 11, and the icon of the protected file 21 that is different from the target application 11 is recognized by the end user. become.

Further, the protect data 22 is composed of a system file set invisible and different from the protect file 21 in practice as shown and described in the configuration taken in the protect file 21 for convenience. Therefore, the protection file 21 that can be operated by the user and the invisible protection data 22 that cannot be operated by the user are used as a set. With this configuration, the content of the executable file outside of the file 21 cannot be changed. The data 22 allows the protect file 21 to update the contents.

That is, the protect file 21 is configured by adding protect data 22 (system file) including a protect program to the target application 11. When this protect file 21 is executed, it is recorded in the protect data 22 that it has been executed. In other words, for example, when the activation of the target application 11 is allowed up to 5 times and is protected, the number of activations of the target application 11 is recorded in the protection data 22.

The control device 6 stores the generated protect file 21 in the directory where the target application 11 has been stored (step S5), and ends the process. In this embodiment, the target file 11 is stored in the directory where it was stored. However, the present invention is not limited to this, and the target file 11 can be stored in an appropriate location by causing the user to select a storage location.

[0067] With the above configuration and operation, it is possible to display an appropriate screen on the display device 3, accept an input operation by the user with the input device 2, and protect the target application 11 with the protect file creation program 20 become.

Therefore, the user (file provider, that is, application program developer) can protect the target application 11 to be protected without having any knowledge about protection. When applying this protection, the user only has to select the type of protector and select the target application 11, so that the protector can be easily applied in a short time.

[0069] Since the protection type can be selected from a user restriction, a usage limit, a usage day limit, a usage period restriction, a serial restriction and a plurality of protection types, the user can use it for the target application 11. You can easily apply the type of protection that suits your needs.

[0070] The user can distribute the completed protected file 21 by selling it. The end user who has acquired the protected file 21 distributed in this way can activate the protected file 21 and use the target application 11 within the range permitted by the protection. In other words, the end user 1 cannot directly start the target application 11, but can start the target application 11 only by using the same PC (personal computer) as the first start-up, for example, in the case of serial restriction by starting the protect file 21. Allowed by protection, such as being able to start Available within the allowed range.

FIG. 6 shows a flowchart of operations performed by the control device 6 when the completed protect file 21 is activated. In this embodiment, the case where the protection file creation system 1 is executed by a computer will be described. However, the same operation is performed when the protection file creation system 1 is executed by another computer.

[0072] When the protect file 21 is activated by the user operating the input device 2, the control device 6 is set to the protect data 22 in accordance with the protect program in the protect file 21 (for example, integrated with the protect data 22). It is determined whether or not the protected type is user restriction (step S11).

[0073] If the protection type power is a user restriction (step S12: Yes), the control device 6 displays the input screen 60 shown in FIG. 7 on the display device 3, and the user name and password for the end user. Is prompted (step S12). The input screen 60 is provided with a user name input text box 61 for inputting a user name, a password input text box 62 for inputting a password, an OK button 63, and a cancel button 64.

[0074] The control device 6 determines whether the input user name and password are stored in the protected data 22 and completely match the user name and password, and if they match (step S13: Yes). ), Starts the target application 11 loaded in the protect file 21 (step S14), and ends the process.

[0075] If the entered user name and password are not stored in the protect data 22 (step S13: No), the control device 6 displays the error message screen 70 shown in FIG. 8 on the display device 3 ( Step S15), the process is terminated. The error message screen 70 is provided with a message display section 71 and an OK button 72.

If there is no user restriction in step S11 (step S11: No), the control device 6 determines whether or not the protection type is the number of times restriction (step S16). If the number of times is limited (step S16: Yes), refer to the protect data 22 to obtain the number of times of use that is permitted to use and the actual number of times of activation, and check whether the number of times of activation is within the number of times of use ( Step S 17).

[0077] When the number of activations is within the number of usages (step S18: Yes), the controller 6 activates The number of activations is updated by adding 1 to the number of times and storing the data in the out-of-protection data 22 (step S19), the target application 11 loaded in the protect file 21 is activated (step S20), and the process is terminated.

[0078] If the number of activations has reached the number of uses or is greater than the number of uses (step S1 8: No), the control device 6 displays an error message screen (Fig. 8 and message display 71 message). (Screen with different content) is displayed on display device 3 (step S21), and the process ends.

[0079] When the number of times is not limited in step S16 (step S16: No), the control device 6 registers the acquired date in the protect data 22 (step S28) and activates the target application 1 1 in step S27). (Step S25), and the process ends.

[0080] If the activation is not the first time (step S26: No), the controller 6 displays an error message screen (a screen in which the message content of the message display unit 71 is different from that in FIG. 8) on the display device 3 (step S29). ), The process ends.

[0081] When the number of days is not effective in step S22 (step S22: No), the control device 6 determines whether or not the protection type is a time limit (step S30). If the time limit has been reached (step S30: Yes), refer to the protection data 22 to obtain the usage time limit, which is the time limit for permitting use, and the current date has been acquired and the time limit has not passed. (Step S31).

[0082] When the usage time limit has not elapsed (step S32: Yes), the control device 6 activates the target application 11 captured in the protected file 21 (step S33), and ends the process.

[0083] When the expiration date has passed (step S32: No), the control device 6 displays an error message screen (a screen in which the message content of the message display unit 71 is different from that in Fig. 8). (Step S34), and the process is terminated.

[0084] If there is no time limit in step S30 (step S30: No), that is, if there is no user limit, number of times limit, number of days limit, and time limit, controller 6 determines that the limit is serial. To do. Therefore, the control device 6 refers to the protect data 22 to acquire the serial number and also stores the protect file 21 in the storage device 7 Is obtained from the storage device 7, and it is confirmed whether or not both serial numbers match (step S35).

[0085] If the serial numbers match (step S36: Yes), the control device 6 activates the target application 11 captured in the protect file 21 (step S37), and ends the process.

[0086] When the serial numbers do not match (including the case where the serial number is not registered in the protect data 22) (step S36: No), the control device 6 determines whether or not it is the first time to start ( Step S38). This determination is made based on whether the serial number is registered in the protect data 22 or not.

[0087] If it is the first activation (step S38: Yes), the control device 6 acquires the serial number from the storage device 7 storing the protect file 21 (step S39), and protects the acquired serial number. Register to data 22 (step S40) and launch target application 11.

(Step S37), the process ends.

[0088] If the activation is not the first time (step S38: No), the control device 6 displays an error message screen (a screen in which the message content of the message display unit 71 is different from that in Fig. 8) on the display device 3 (step S41). ), The process ends.

[0089] Through the above operation, the protect file 21 executes the applied protection, and if it is used within the range permitted by the protector, executes the target application 11. Otherwise, the target application 11 You can't do that, you can power S.

[0090] If the protection type is a user restriction, it is possible to prevent the target application from being used by a user other than a regular user.

If the protection type is limited to the number of times, the target application 11 can be prevented from being used more than the specified number of times.

If the protection type is the day limit, it is possible to prevent the target application from being used for more than the number of days determined from the first activation date.

If the protection type is a time limit, it is possible to prevent the target application 11 from being used beyond the set time limit.

If the protection type is serial restriction, the target application on a PC other than the PC that is started for the first time 11 Can be prevented from being used.

[0091] In the above embodiment, the configuration may be such that the server S is protected via the network with the power S configured to protect the target application 11 with a computer operating alone.

In other words, the target application 11 can be protected using another computer (for example, a server) connected via a network such as a LAN.

[0092] In this case, if the protected file creation program 20 is installed on a server connected to the network, and a terminal (computer) connected to the network accesses the server and protects it, then.

[0093] Specifically, the server is accessed by the terminal, and each item is input from the terminal on the protection condition setting screen 30 displayed by the protect file creation program 20, and the file designation screen 40 and the file selection screen are also entered. If each item is entered from the terminal in 50, the server acquires the target application 11 from the terminal, creates a protected file 21, and the server sends the protected file 21 to the terminal.

Thus, even a user who does not have the protect file creation program 20 can easily create a protect file 21 that protects the target application 11 by accessing a server on the network.

[0095] In addition, the protect file 21 is composed of the protect programs corresponding to all the protection types. However, for each protection type, a protection program that executes only the protection is prepared, and the protection file corresponding to the set protection type is prepared. The protect file 21 may be configured by a program. In this case, the file size of the protected file 21 can be reduced.

[0096] Although the target application 11 is configured by an application that is an executable program, it is not limited to an application, and music data (extension: MP3, WAV, etc.), video data (extension: mpg, etc.) and text As data such as data (extension: txt, doc, etc.)

[0097] In the correspondence between the configuration of the present invention and the above-described embodiment, the target file of the present invention corresponds to the target application 11 of the embodiment. Similarly, the protect content designating means is a protect type selection button. Corresponding to 31, the target file designation means is the file name input text Corresponding to box 41, the protect file generating means corresponds to the control device 6 that executes step S4, the output means corresponds to the control device 6 that executes step S5, and the target file designation process is performed in step S2. The protect file generation processing corresponds to step S4, the output processing corresponds to step S5, and the protection content corresponds to the protection type, but the present invention is limited to the configuration of the above-described embodiment. There are many more embodiments than can be achieved.

[0098] In the above, the case where the target application 11 is taken into the RAM and the protected file 21 is generated has been described. Instead of taking the target application 11 into the RAM, the target application 11 is secured in the storage device 7 (hard disk). The target application 11 may be taken into the virtual memory area. That is, the target application 11 is copied to another area in the storage device 7 in which the target application 11 is stored. After that, the target application 11 with a large capacity is processed in the storage device 7, and RAM is used if necessary.

In this way, the protect file 21 can be created even when the capacity of the target application 11 is larger than the capacity of the RAM. In addition, the capacity of the target application 11 varies. Assuming that the protected file 21 of the target application 11 having a large capacity is created, it is necessary to increase the capacity of RAM (RAM module) that is more expensive than the storage device 7. Absent.
