  FIG. 1 shows an example of a system according to the embodiment. This system includes a mobile terminal 100 and a device 200.

  The mobile terminal 100 is an information processing terminal carried by a user, and a smartphone, a tablet terminal, and the like are examples. The device 200 is a device that provides some processing function to the user. The device 200 is, for example, a printer, a scanner, a facsimile machine, a multi-function machine (an apparatus having a function of a printer, a scanner, a copier, or the like).

  The mobile terminal 100 includes a lock control unit 110, a device operation application 120, and a communication control unit 130.

  The lock control unit 110 controls screen lock of the mobile terminal 100. The lock control unit 110 is implemented as a function of the OS (operating system) of the mobile terminal 100, for example. In the screen lock control, a normal UI (user interface) screen (for example, a home screen or the like) for displaying a lock screen on the display of the mobile terminal 100 or canceling the display of the lock screen and accepting an operation from the user is displayed. Or display. Note that the lock screen locks the operation so that a person other than the owner of the terminal cannot use it without permission (that is, operations other than the unlocking operation are not accepted, or operations other than the unlocking operation are limited) This is the screen that is displayed when To release the screen lock (that is, the state in which the lock screen is displayed), a predetermined release operation is required. The lock control unit 110 prepares several types of methods such as PIN code input, password input, pattern input, fingerprint authentication, and face authentication as the release operation. The pattern input is an operation of drawing a locus (pattern) by a touch operation of a fingertip or the like on a lock screen on a touch panel which is a display of the mobile terminal 100. For example, one of methods for unlocking a screen with an Android (registered trademark) OS. Adopted. The user sets a release operation used by the user in the lock control unit 110 in advance among the plurality of release operations, and also uses personal authentication information (for example, PIN code, password, pattern, fingerprint information, face information) used for the release operation. , Iris information). Information processing for setting the release operation method and personal authentication information is performed by the lock setting unit 112. When the user tries to operate the mobile terminal 100, the screen lock is released by inputting the personal authentication information to the lock screen displayed on the display by the set release operation method. The screen lock release process performed by the lock control unit 110 is an authentication process for a user who intends to use the mobile terminal 100.

  The device operation application 120 is an application program that executes processing for operating the device 200 from the mobile terminal 100. The device operation application 120 is installed in a computer in the mobile terminal 100, and is executed by a processor in the mobile terminal 100, whereby a device for operating the device 200 and a device instruction according to an instruction from the user with respect to the UI. Processing such as a process instruction and transmission / reception of data to be processed is executed for 200.

  The device operation application 120 holds information on the device user ID 122. The device user ID 122 is a user ID (identification information) of a user account that the user (that is, the owner of the mobile terminal 100) has in the device 200. This information is set in the device operation application 120 by the user. When the user uses the device 200 locally, the user inputs the user ID and password to an input device attached to the device 200 for authentication, and the same user ID is used for the simple authentication operation of the present embodiment. For this reason, it is held in the portable terminal 100. The device user ID 122 may not be the user ID of the user in the device 200 but may be other information that can uniquely derive the user ID.

  In addition, the device operation application 120 includes a use request processing unit 124. The usage request processing unit 124 processes a usage request when the user (owner) of the mobile terminal 100 uses the device 200. In the present embodiment, in order to simplify the authentication process when using the device 200 from the mobile terminal 100, the screen lock of the mobile terminal 100 is released and the user (owner) of the mobile terminal 100 authenticates the device 200. Link with. That is, when the screen lock is released, the mobile device 100 (usage request processing unit 124) includes the device user ID 122 of the user and specific information indicating that the screen lock is released. Use request information is sent to the device 200. Then, the device 200 that has received the usage request information from the mobile terminal 100 permits the user to log in to the device 200 corresponding to the device user ID 122 included in the information, and the user can operate the device 200 from the mobile terminal 100. Like that. In this case, since the screen lock of the mobile terminal 100 is released, the mobile terminal 100 should be operated by a valid user (owner of the mobile terminal 100) indicated by the device user ID 122. Since the usage request information indicates that the usage request is from the mobile terminal 100 operated by a legitimate user, the device 200 trusts that, and inputs authentication information such as a password from the user, The authentication process for the authentication information is omitted and the login of the user is permitted.

  The communication control unit 130 performs control for data communication with the outside of the mobile terminal 100 (for example, the device 200). The communication control unit 130 may communicate with the device 200 via wireless communication such as a wireless LAN (local area network). Further, this wireless communication may be such that wireless devices are directly connected by wireless communication, such as Wi-Fi Direct (registered trademark) or Bluetooth (registered trademark).

  The device 200 includes an authentication processing unit 210, an operation reception unit 220, and a communication control unit 230 in addition to a mechanism for a function provided to a user (for example, scanning, printing, fax transmission, etc. in the case of a multifunction device). .

  The authentication processing unit 210 performs user authentication for a user who intends to operate the device 200. For example, when a user inputs a user ID and authentication information to an input device attached to the device 200 (for example, a user ID or password input field displayed on the touch panel or an IC card reader), the authentication processing unit 210 inputs the user ID and authentication information. The user authentication is executed based on the received information. The authentication processing unit 210 receives authentication information such as a user ID and a password from a device such as the mobile terminal 100 or a PC (personal computer) on the network, and performs user authentication based on the information. In addition to the normal authentication function, the authentication processing unit 210 authenticates the user ID and the user ID when receiving usage request information (including the device user ID 122 and specific information indicating that the screen is unlocked) from the mobile terminal 100. A normal authentication process based on the information is omitted, and the user corresponding to the device user ID 122 is allowed to use the device 200 (for example, login is permitted).

  The operation reception unit 220 receives an operation on the device 200 from a logged-in user. The device 200 executes processing corresponding to the operation received by the operation receiving unit 220.

  The communication control unit 230 performs control for data communication with the outside of the device 200 (for example, the mobile terminal 100). The communication control unit 230 may support a wireless LAN standard such as Wi-Fi Direct (registered trademark).

  As described above, in the present embodiment, release of the screen lock of the mobile terminal 100 (that is, user authentication for using the mobile terminal 100) is linked to user authentication in the device 200. Here, the user releasing the screen lock of the mobile terminal 100 is not limited to using the device 200. For this reason, when the mobile terminal 100 (use request processing unit 124) performs a process of sending use request information to the device 200 every time the screen lock is released, the process is performed even when the user does not intend to use the device 200. It will be done and it is useless. Therefore, in the present embodiment, as an example, in addition to the normal screen unlocking for using the mobile terminal 100, the dedicated screen unlocking for using the device 200 is set in the mobile terminal 100, so that the user When the device 200 is used from the portable terminal 100, the latter screen unlocking is used.

  The distinction between normal screen lock release and screen lock release when using the device 200 is realized by using different information as personal authentication information input for the release operation in one example. For example, when a pattern input method is used as a release operation for screen lock release, different patterns (this corresponds to personal authentication information) are used for normal screen lock release and screen lock release when using the device 200. This is an example. As another example, a PIN code or a password to be input for unlocking the screen may be different between normal screen unlocking and screen unlocking when using the device 200.

  As another example, an operation different from the unlocking operation used for normal screen unlocking may be assigned to the unlocking operation for unlocking the screen when using the device 200. For example, a fingerprint input method is used for normal screen unlocking, but a PIN code input is used when the device 200 is used.

  In this case, when a specific operation such as a switching button being pressed or a gesture operation such as a flick operation is performed in a state where a normal screen unlock screen is displayed, the device 200 may be used. The screen may be switched to a screen unlocking screen, or the screen unlocking screen when the device 200 is used may be switched to a normal screen unlocking screen.

  In any of the above cases, when using the device 200, the user inputs a special release code (an example of a release operation different from the normal case) that is different from the one that is input when releasing the normal screen lock. The lock setting unit 112 accepts a setting of a dedicated release code (referred to as a device use dedicated code) when using the device 200 in addition to a normal unlock code (referred to as a normal code).

  As described above, an example of the processing procedure of the mobile terminal 100 at the time of unlocking the screen when using a special release code different from normal when using the device 200 will be described with reference to FIG.

  The procedure of FIG. 2 is started when the mobile terminal 100 is turned on or a sleep state canceling operation is performed. When the sleep release or the like is performed, the lock control unit 110 of the mobile terminal 100 displays a predetermined lock screen on the display of the mobile terminal 100 (S10), and receives an input of a release code for the lock screen from the user (S12). . Next, the lock control unit 110 determines whether the release code input in S12 is a normal code, a device use dedicated code, or any other code (S14). If the input release code does not correspond to either the normal code or the release code, the lock control unit 110 does not release the screen lock (not shown). If the input release code is a normal code, the lock control unit 110 releases the screen lock and displays a predetermined home screen on the display (S16). Since S16 and subsequent steps are normal processing of the mobile terminal 100, description thereof is omitted.

  When the cancellation code input in S12 is a device use dedicated code, the mobile terminal 100 causes the communication control unit 130 to establish communication with a nearby device 200 (S18). The communication between the portable terminal 100 and the nearby device 200 here may be based on a short-range wireless connection method such as Wi-Fi Direct or Bluetooth (registered trademark). In S18, when the device 200 that can be connected by the short-range wireless connection method is not found from the mobile terminal 100, the mobile terminal 100 displays an error message indicating that there is no device available nearby, for example, on the lock screen. It may be displayed above.

  When the wireless communication with the nearby device 200 can be established in S18, the mobile terminal 100 acquires information on the current state from the device 200 using the communication (S20). The state of the device 200 acquired here is a state of whether or not the device 200 is currently being used (that is, for example, whether printing or other processing is being performed). The portable terminal 100 determines whether or not the device 200 is currently being used from the acquired state information (S22). If it is determined that the device is being used, the lock control unit 110 displays on the lock screen that the device 200 is currently being used (S24), and returns to S10.

  When it is determined in S22 that the device 200 is not currently in use, the device operation application 120 displays a job execution screen on the display of the mobile terminal 100 (S26), and the use request processing unit 124 informs the device 200 of use request information. Is transmitted (S28). Here, the job execution screen is a UI screen for operating the device 200. In accordance with the display on the job execution screen, the user selects a process to be executed by the device 200 and inputs parameters for the process. Further, the use request information transmitted in S28 includes the device user ID 122 and specific information indicating that the screen lock has been released. The device 200 that has received the usage request information permits the login of the user corresponding to the device user ID 122 included therein, and the user from the portable terminal 100 that follows this (until time-out occurs due to logout or no operation). The operation instruction is accepted. When the user's input on the job execution screen is completed and the user instructs the start of the job indicated by the input, the device operation application 120 sends a job execution instruction including the content of the input to the device 200 ( S29). The device 200 executes the job according to the job execution instruction.

  Next, an example of a processing procedure executed by the device 200 will be described with reference to FIG.

  In this procedure, when receiving an access from the mobile terminal 100, the device 200 determines whether or not the use request information described above has been sent (S102). If usage request information is not sent, normal processing (for example, sending an input screen such as a user ID and password to the mobile terminal) is executed. On the other hand, if it is determined in S102 that the usage request information has been sent, the authentication processing unit 210 of the device 200 regards that the user corresponding to the device user ID 122 included in the usage request information has been successfully authenticated, User login is permitted (S104). Then, a job execution instruction sent from the portable terminal 100 is received, and the job is executed according to the instruction (S106).

  In the processing procedure shown in FIG. 2, when the state of the device 200 acquired in S20 after the screen lock is released is “in use”, the mobile terminal 100 simply displays that the device 200 is in use and displays the lock screen. Returned to (S10). As another example of this, in that case, it is also possible to accept a use reservation from the user. An example of the processing procedure of the mobile terminal 100 in this case is shown in FIG. The procedure shown in FIG. 4 is replaced after S22 in the procedure of FIG.

  In this procedure, when it is determined in S22 that the state of the device 200 is “in use”, the mobile terminal 100 displays a screen for inquiring whether to make a use reservation (S30). When the user instructs the screen not to make a use reservation (the determination result in S32 is No), the mobile terminal 100 returns to the lock screen display (S10). When the user instructs to make a reservation for use (Yes in S32), the device operation application 120 displays the job execution screen on the display of the portable terminal 100 (S34) and the use request processing unit 124. Thus, the usage request information is transmitted to the device 200 (S36). In accordance with the display on the job execution screen, the user selects a process to be executed by the device 200 and inputs parameters for the process. When the user's input on the job execution screen is completed and the user instructs the start of the job indicated by the input, the device operation application 120 sends a job execution instruction including the content of the input to the device 200 ( S38). The device 200 queues the received job. This completes the job reservation (this job is called a reservation job). The device 200 starts executing the reserved job after completing the execution of the job currently being executed (other job in the queue having a higher priority than the reserved job), and notifies the mobile terminal 100 of the execution start. I do. After S38, the device operation application 120 waits for a reservation job execution start notification from the device 200 (S40, S42). When the notification is received (Yes in S42), the device operation application 120 is displayed on the screen of the portable terminal 100. A screen indicating that the reserved job has been started is displayed (S44). The user sees the screen and knows that the job has started. For example, when the job is a print job, the user sees the execution start notification and goes to the device 200 to acquire the print result. If S42 is No, the process returns to S40.

  Now, the device use dedicated code used in the above embodiment needs to be different from the normal code that is the screen lock release code when the mobile terminal 100 is normally used. The lock setting unit 112 may perform guidance processing for selecting a code different from the normal code when the user sets a device use dedicated code. As the guidance process, for example, when the code entered by the user as a device use-only code matches the normal code that has already been set, this is notified on the screen, and a different code is set for the user. You may perform the process which prompts. At this time, the lock setting unit 112 may propose another code (or a completely different code) generated by slightly changing the normal code as a candidate for the device use dedicated code. As another example of the guidance process, a normal code that has already been set may be displayed on the screen, and a different code may be set as a device use dedicated code.

  In the above example, as the release code (release operation) for releasing the screen lock of the mobile terminal 100, in addition to the normal code used when the mobile terminal 100 is normally used, the device use dedicated code used when using the device 200 is used. By preparing the screen, it is possible to distinguish whether or not the user intends to use the device 200 when the screen lock is released. On the other hand, in the modified example described below, it is estimated by another method whether or not the user intends to use the device 200 when the screen is unlocked.

  FIG. 5 illustrates the configuration of the system of this modification. This system configuration differs from the system configuration shown in FIG. 1 in that the mobile terminal 100 and the device 200 include BLE (Bluetooth Low Energy: registered trademark) modules 140 and 240, respectively. The BLE modules 140 and 240 are devices for performing wireless communication conforming to the BLE standard. The BLE standard supports a function of detecting an approximate distance to a communication partner from the radio wave intensity at the time of communication with the communication partner, and the BLE modules 140 and 240 also have this function. In this modification, when the mobile terminal 100 is approaching the device 200 when the screen lock is released, it is determined that the user of the mobile terminal 100 intends to use the device 200.

  FIG. 6 shows a processing procedure of the mobile terminal 100 in this modification. The procedure in FIG. 6 is a modification of the procedure in FIG. 2, and the same steps as those shown in FIG.

  In the procedure of FIG. 6, after receiving the screen lock release code input in S <b> 12, the mobile terminal 100 communicates with the BLE module 240 of the nearby device 200 through the BLE module 140, and between the BLE modules 140 and 240. The distance is calculated periodically (for example, every 0.1 seconds), and the temporal change of the distance is obtained (S50). And the lock control part 110 determines whether the portable terminal 100 is approaching the apparatus 200 from the change of the calculated | required distance (S52). And when it determines with approaching (the determination result of S52 is Yes), since it is estimated that the user of the portable terminal 100 intends to use the device 200, the process proceeds to S18 and after in FIG. The use request processing unit 124 sends use request information to the device 200 to log in to the device 200. On the other hand, if the determination result in S52 is No, it is presumed that the user does not intend to use the device 200, so that the lock control unit 110 proceeds to S16 to release the normal screen lock and displays the home screen. To do.

  In the procedure of FIG. 6 described above, if the user (mobile terminal 100) is approaching the device 200 when the screen is unlocked, it is determined that the user intends to use the device 200. However, when the user simply passes the device 200, the screen lock may be released in an attempt to operate the mobile terminal 100. FIG. 7 shows an improved example of the procedure of FIG. 6 taking such a case into consideration.

  In the procedure of FIG. 7, when it is determined that the mobile terminal 100 is approaching the device 200 in S52, the mobile terminal 100 releases the screen lock and displays the home screen (S54). ) Is started. In this monitoring, it is determined whether or not the user has activated an application other than the device operation application 120 within a predetermined period (for example, several seconds) after the display of the home screen in S54 (S56). If the app activated by the user within the predetermined period is an app other than the device operation app 120 (the determination result in S56 is Yes), the user locks the screen to use the app instead of using the device 200. Can be determined to have been canceled. In this case, the mobile terminal 100 performs processing of the activated application. On the other hand, when the device operation application 120 is opened within the predetermined period, the user has an intention to use the device 200, so the process of the mobile terminal 100 proceeds to S18, and the device 200 is used. Processing such as transmission of usage request information.

  In the modification described with reference to FIGS. 5 to 7, it is determined whether or not the mobile terminal 100 is approaching the device 200 at the time of unlocking the screen using the BLE distance measurement function. It is only an example. Other distance measurement systems using radio waves or the like may be used. For example, the positions of the mobile terminal 100 and the device 200 are obtained using a positioning system such as GPS (Global Positioning System), and the positions of both of them with time are determined. A change in the difference (distance) may be obtained.

  Still another modification will be described with reference to FIGS. Also in this modified example, as in the modified examples of FIGS. 5 to 7, the user uses the device 200 from the situation when the normal unlock code is input without using the device use dedicated code for unlocking the screen. It is determined whether or not. In this modified example, as shown in FIG. 8, the device 200 has a known gaze detection sensor 250, and when the user releases the screen lock of the mobile terminal 100, the gaze detection sensor 250 detects the gaze. If so, it is determined that the user has an intention to use the device 200. That is, when the screen lock is released (for example, immediately after the release), if the user looks at the device 200, the user determines that he / she intends to use the device 200.

  FIG. 9 shows an example of the processing procedure of the mobile terminal 100 in this modification, and the same steps as those in the procedure shown in FIG. In this procedure, when the portable terminal 100 receives an input of a screen unlock code in S12, the mobile terminal 100 notifies the device 200 that the lock has been released (S60). This notification only needs to indicate that the screen lock has been released, and does not need to include the use request information described above. This notification may be performed by a known wireless communication method such as Bluetooth or Wi-Fi Direct. After S60, the mobile terminal 100 waits for a request for transmission of use request information from the device 200 (S62). If the usage request information is not requested from the device 200 even after waiting for a predetermined period, the mobile terminal 100 proceeds to S16 in FIG. 2 and displays the home screen. When the transmission of usage request information is requested from the device 200 in S62, the mobile terminal 100 proceeds to S18 and subsequent steps in FIG. 2 and performs processing such as transmission of usage request information for using the device 200.

  FIG. 10 is an example of the processing procedure of the device 200 in this modification. In this procedure, when the device 200 receives access from the mobile terminal 100, the device 200 determines whether or not it is a notification of unlocking (S110). If it is determined that the notification is not a lock release notification, the process proceeds to S102 in FIG. 3 to determine whether usage request information has been received, and thereafter the same processing as in FIG. 2 is performed. On the other hand, if it is determined in S110 that the unlock notification has been received, the device 200 determines whether or not the line-of-sight detection sensor 250 detects the line of sight (S112). If the line of sight is not detected, the device 200 does not perform any special processing on the mobile terminal 100 thereafter. In this case, the mobile terminal 100 waits for a request for use request information from the device 200 after the device 200 sends a lock release notification. The processing related to the device 200 is not executed. When the determination result in S112 is Yes, the device 200 requests the portable terminal 100 to transmit usage request information (S114). In the portable terminal 100 that has received this request, since the determination result in S62 is Yes, the process proceeds to S18, and processing for transmitting use request information is executed. When the mobile terminal 100 transmits the use request information, the device 200 executes the processing from S102 onward in FIG. 3 and permits the user to log in.

  In the example described above, it is assumed that when the user tries to use the device 200, the screen lock of the mobile terminal 100 at hand is released. However, the screen lock has already been released in the method of the above embodiment and the modified example. The present invention can also be applied to a case where a user carrying the portable terminal 100 that has been used can use the device 200. For example, when the user who has the mobile terminal 100 whose screen lock is released reaches a position where the user can communicate with the device 200 and starts the device operation application 120, the use request processing unit 124 requests the device 200 to use the device operation application 120. Information may be transmitted. In addition, when the user who has the mobile terminal 100 in a state where the screen lock is released and the device operation application 120 is activated has arrived at a position where communication with the device 200 is possible, the use request processing unit 124 requests the device 200 to use the device 200. Information may be transmitted.

  In the example shown above, the process of transmitting the usage request information to the device 200 is performed by the device operation application 120, but may be performed by the lock control unit 110.

  Further, in S12 of the procedure in FIG. 2, the input of both the normal code and the device use dedicated code is accepted as the unlock code, but the device use dedicated code may not be accepted depending on the situation. . For example, consider a case where the device 200 has a function of accepting a use (use) reservation from a user. When displaying the unlock screen on the mobile terminal 100, if the device 200 is reserved by another user (a user other than the owner of the mobile terminal 100) (that is, the display time is reserved by another user) If it corresponds to the time zone in which the device 200 is scheduled to be used), it is considered that another user should be using (or will use) the device 200. At this time, even if an attempt is made to use the device 200 from the portable terminal 100, the device 200 cannot be used unless the use related to the reservation is completed. Therefore, in such a case, even if the input of the device use dedicated code is accepted and the authentication procedure is speeded up, there is a high possibility of being wasted. Therefore, when displaying the unlock screen, the mobile terminal 100 does not accept input of a device use dedicated code if the device 200 is reserved by another user (for example, the normal code input screen is displayed and the device use is displayed). Do not display the dedicated code input screen). Whether or not the device 200 is reserved by another user may be detected by making an inquiry from the portable terminal 100 to a server that manages the use reservation of the device 200 or the device 200 group.
