Description

  The present invention relates to the use of protected (use restricted) data.

  There are image forming apparatuses such as printers, multifunction machines, copiers, and facsimile machines. In order to make the image forming apparatus easy to use, the image forming apparatus may be linked with another apparatus. For example, the image forming apparatus and the portable terminal may be linked. Patent Document 1 describes an example of a technology for securing information security of an image forming apparatus and a portable terminal cooperating with the image forming apparatus.

  Specifically, in Patent Document 1, the biological information is acquired by communicating with the personal information storage device storing the biological information of the user, the biological information is read from the human body of the user, and the acquired biological information is read and obtained. There is described an image forming apparatus for authenticating a user by comparing the biometric information with biometric information pre-registered in at least one of the image forming apparatus main body and a server accessible by the image forming apparatus. With this configuration, authentication between the image forming apparatus and the personal information storage device is facilitated (see Patent Document 1: Claim 1, paragraph [0014], etc.).

JP, 2010-183306, A

  Data may be stored on the imaging device. For example, a file used for printing may be stored in the image forming apparatus. Then, there is a case where it is desired to store data which can not be seen by others in the image forming apparatus. The data that the user does not want to see is, for example, data including confidential information. It is not possible to save data in a shared area that you do not want others to see.

  Therefore, a personal storage area may be provided in the image forming apparatus. The data stored in the personal storage area can be viewed and used only by the stored person (the creator of the data). The use (access) of other people's data is restricted. Usage restrictions can prevent unauthorized users from viewing or using data. However, there is a problem that there is a case that another user may want to use data whose usage is restricted. For example, when going out, it may be desirable to have a specific person print a file whose use is restricted. In other words, there is a case where it is desired to make another person temporarily use protected data that prohibits the use of the other person.

  The technology described in Patent Document 1 relates to authentication of an individual. However, according to the technology described in Patent Document 1, it is impossible to temporarily allow another person to use protected data. Therefore, the technique described in Patent Document 1 can not solve the above problem.

  In view of the problems of the prior art described above, the present invention allows protected (temporarily prohibited) data to be temporarily used by anyone other than the creator in a manner desired by the creator.

  An image forming system according to the present invention includes a first communication device, a second communication device, and an image forming device. The first communication device receives an assignment operation. The second communication device communicates with the first communication device. The image forming apparatus communicates with the second communication apparatus. The application operation includes an operation of selecting protected data to which a reference key is attached. Further, the giving operation includes an operation of selecting the second communication device to which the selected use right of the protection data is given. When the first communication device receives the assignment operation, the first communication device transmits authorization information including the reference key to the second communication device set by the assignment operation. The second communication device stores the received authorization information. The second communication apparatus transmits the received authorization information to the image forming apparatus. When the image forming apparatus receives the authorization information transmitted from the second communication apparatus, the image forming apparatus calls specific protection data which is the protection data to which the reference key is added, which is included in the received authorization information. . The image forming apparatus receives a job execution instruction based on the called specific protection data. When the execution instruction is received, the image forming apparatus executes a job based on the specific protection data.

  According to the present invention, protected data (data prohibited from being used by another person) can be temporarily used by someone other than the creator in a manner desired by the creator of the data. The use of protected data can be permitted, and an easy-to-use imaging system can be provided.

Next, an example of the flow of registration of the protection data 5 in the image forming system 100 according to the embodiment will be described using FIGS. 6 and 7. FIG. 6 is a view showing an example of the flow of registration of protection data 5 in the image forming system 100 according to the embodiment. FIG. 7 is a diagram showing an example of the protection data 5 according to the embodiment.

  The protected data 5 is data in which the use by others is prohibited in principle. Only the registrant of protected data 5 can use protected data 5. A person who is not a registrant can use the protected data 5 registered by another person when receiving the right of use. The start of FIG. 6 is when the protection registration software 16 is activated by the first communication device 1 for registration of the protection data 5. After the lock of the protection registration software 16 is released, the user of the first communication device 1 can activate the protection registration software 16. Unlocking requires authentication. Fingerprint authentication and password can be used for unlocking.

  When performing fingerprint authentication, the first communication device 1 includes a fingerprint reading sensor. In addition, the first storage unit 11 stores fingerprint data of a usable person (owner) of the first communication device 1. The fingerprint reading sensor reads the fingerprint of the finger touching the sensor. The fingerprint reading sensor that has read the fingerprint outputs fingerprint reading data. The first control unit 10 compares the stored fingerprint data with the fingerprint read data. Based on the comparison, the first control unit 10 determines whether the person who touched the fingerprint reading sensor is the usable person. When it is determined that the user is an available user, the first control unit 10 unlocks the protection registration software 16. Thereby, the protection registration software 16 can be activated. If the first control unit 10 can not determine that the user is the usable person, the lock is not released. When in the locked state, the first control unit 10 does not activate the protection registration software 16.

  When performing authentication using a password, the first storage unit 11 stores the password of the owner (usable person) of the first communication device 1. The first touch panel receives an input of a password. The first control unit 10 checks whether or not the stored password and the input password match. Based on this confirmation, the first control unit 10 determines whether the password input person is the usable person. When they match, the first control unit 10 determines that the password input person is the usable person. When they do not match, the first control unit 10 determines that the person who has entered the password is not an available person. When it is determined that the user is an available user, the first control unit 10 unlocks the protection registration software 16. When the first control unit 10 can not determine that the user is the usable person, the lock of the protection registration software 16 is not released.

  After authenticating the user, the first input device 13 receives an activation instruction of the protection registration software 16. Thereby, the first control unit 10 (first communication device 1) activates the protection registration software 16. After activation of the protection registration software 16, the first input device 13 receives the protection operation (step # 11). The protection operation is an operation for storing the document data 18 as the protection data 5. The protection operation includes an operation of selecting the document data 18 (file) to be registered as the protection data 5. For example, based on the protection registration software 16, the first control unit 10 causes the first display 12 to display a list of the document data 18 stored in the first storage unit 11. The user uses the first input device 13 to select the document data 18 to be registered. Based on the output of the first input device 13, the first control unit 10 recognizes the selected document data 18.

  The document data 18 edited and created by the first communication device 1 can be selected. Also, image data stored in the first communication device 1 can be selected as the document data 18. It is also possible to select, as the document data 18, the read image data which is image data obtained by the reading of the image forming apparatus 3 and transferred to the first communication apparatus 1 by the image forming apparatus 3. Further, the selectable document data 18 is not limited to the data stored in the first communication device 1. The read image data stored in the image forming apparatus 3 can also be selected as the document data 18. Document data 18 stored in the cloud can also be selected.

  In addition, the protection operation includes an operation of selecting the transmission destination of the selected document data 18. After selecting the document data 18 to be protected, the first control unit 10 causes the first display 12 to display a list of transmission destinations of the document data 18. The user selects the destination of the document data 18. The image forming apparatus 3 may be included in the list of transmission destinations. Also, the data storage device 4 may be included in the list of transmission destinations. The user uses the first input device 13 to select a transmission destination. Based on the output of the first input device 13, the first control unit 10 recognizes the transmission destination.

  When the image forming apparatus 3 is selected as the transmission destination of the document data 18 (Yes in Step # 12), the first control unit 10 performs a protection operation toward the third communication unit 35 (image forming apparatus 3). The document data 18 and the address of the first communication device 1 are sent to the first communication unit 14 (step # 13). For example, the first communication device 1 may transmit data and an address by wireless communication by Bluetooth (registered trademark). In the protection registration software 16, the address of the first communication device 1 can be preset using the first input device 13. The address is, for example, an e-mail address. Addresses other than e-mail addresses may be set. The set address is stored in the first storage unit 11 in a non-volatile manner. When transmitting the document data 18, the first control unit 10 adds the address set in advance to the document data 18. As a result, the document data 18 selected with the address of the first communication device 1 is transmitted to the image forming device 3. Hereinafter, the address of the first communication device 1 is referred to as a transmission source address 51.

  When the document data 18 is received, the third control unit 30 (image forming apparatus 3) stores the received document data 18 and the transmission source address 51 in the third storage unit 31 (step # 14). Further, the third control unit 30 causes the third communication unit 35 to transmit the received document data 18 and the transmission source address 51 to the fourth communication unit 32 (data storage device 4) (step # 15). For example, the image forming apparatus 3 transmits the document data 18 and the transmission source address 51 via the network.

  When the transmission destination of the document data 18 registered as the protection data 5 is not the image forming apparatus 3 but the data storage device 4 is selected (No in step # 12), the first control unit 10 transmits the fourth communication unit 32 The first communication unit 14 is made to transmit the document data 18 subjected to the protection operation and the transmission source address 51 to the data storage device 4) (step # 16).

  When the document data 18 and the transmission source address 51 are received in steps # 15 and # 16, the fourth control unit 40 (data storage device 4) generates the reference key 6 (step # 17). The reference key 6 is used to search for the protected data 5 to which the usage right is assigned (details will be described later). The fourth control unit 40 generates a unique reference key 6 (see FIG. 9). The reference key 6 includes a plurality of characters, a plurality of numbers, or a plurality of numbers and characters. For example, the reference key 6 is a few to dozens of character strings, number strings, or a combination of characters and numbers. The fourth control unit 40 generates a value different from the reference key 6 used for the protection data 5 stored previously. The fourth storage unit 31 stores a generation algorithm of the reference key 6. For example, the generation algorithm generates the reference key 6 based on the reception date and time of the document data 18.

  The fourth control unit 40 (data storage device 4) non-volatilely stores the generated document data 18 with the reference key 6 as protection data 5 in the fourth storage unit 31 (step # 18). FIG. 8 is a diagram showing an example of the protected data 5 stored in the fourth storage unit 31. As shown in FIG. The fourth control unit 40 adds the related information 50 to the protection data 5 (document data 18). The related information 50 is information related to the protected data 5. The related information 50 includes, for example, a reference key 6, a transmission source address 51, a registration date 52, and a data name 53. The reference key 6 and the transmission source address 51 are received. The fourth control unit 40 includes a clock circuit that measures date and time. The fourth control unit 40 adds the registration date 52 to the protection data 5. Further, the fourth control unit 40 adds the name of the document data 18 (file) to the protected data 5 as the data name 53.

  When the protection data 5 is stored, the fourth control unit 40 (data storage device 4) transmits the protection data information 19 to the fourth communication unit 32 toward the first communication device 1 (step # 19). The protected data information 19 includes the reference key 6. Specifically, the fourth control unit 40 transmits the related information 50 as the protected data information 19.

  When the protection data information 19 is received, the first control unit 10 (first communication device 1) stores the protection data information 19 in the first storage unit 11 in a non-volatile manner (step # 110). Thereby, the first communication device 1 can recognize the reference key 6 attached to its own protection data 5. Then, the flow ends (end). Registration of protection data 5 is completed.

  The start of FIG. 8 is the point in time when the authorization software 17 is activated by the first communication device 1 for the authorization of use of the protection data 5. After unlocking the authorization software 17, the user of the first communication device 1 can activate the authorization software 17. Unlocking requires authentication. Fingerprint authentication and password can be used for unlocking. The unlocking method is the same as in the case of FIG. Thereby, it is possible to prevent unauthorized assignment of the use authority of the protection data 5 by a person who does not have the authority to use the first communication device 1.

  After authenticating the user, the first input device 13 receives an activation instruction of the authorization software 17. Thereby, the first control unit 10 (first communication device 1) activates the authorization software 17. After activating the authorization software 17, the first control unit 10 causes the first display 12 to display the authorization setting screen 7 (step # 21). Then, the first input device 13 (first communication device 1) receives the assignment operation (step # 22). The giving operation includes an operation of selecting the protection data 5 to which the use right is to be given, and an operation of selecting the second communication device 2 to which the use right is to be given.

  FIG. 9 shows an example of the authorization setting screen 7. As shown in FIG. 9, the authorization setting screen 7 includes a first input field 71, a second input field 72, a third input field 73, a fourth input field 74, a fifth input field 75, and a first check box C1. , A second check box C2 is provided.

The third input field 73 to the fifth input field 75 are optional input fields. It is not necessary to enter numbers or letters in any of the input fields.

  The first input field 71 is a field for selecting the protected data 5 to which the usage right is to be given. For example, the first input field 71 is a pull-down menu type input field. When the right end of the first input field 71 is operated, the first control unit 10 causes the first display 12 to display a list of data names 53 of the registered protection data 5 using the first communication device 1. Specifically, the first control unit 10 extracts the protected data information 19 stored in the first storage unit 11. The first control unit 10 causes the first display 12 to display a list of data names 53 included in the extracted protection data information 19.

  The second input field 72 is a field for selecting the second communication device 2 to which the use right of the selected protection data 5 is given. For example, the second input field 72 is a pull-down menu type input field. When the right end of the second input field 72 is operated, the first control unit 10 causes the first display 12 to display a list of second communication devices 2 that can communicate with the first communication device 1. For example, the first control unit 10 causes the first display 12 to display a list of the second communication devices 2 that can communicate by Bluetooth. Alternatively, the first control unit 10 may cause the first display 12 to display a list of addresses included in the address book stored in the first communication device 1. The second input field 72 may not be of the pull-down menu type. The second input field 72 may be a field for directly inputting the address of the second communication device 2.

In the third input field 73, the number of days is input. A final deadline is entered in the fourth entry field 74. The first input device 13 receives an input to the third input field 73 or the fourth input field 74. The first check box C1 and the second check box C2 are check boxes for selecting which one of the value input in the third input field 73 and the value input in the fourth input field 74 to use. . When the number of days or the time limit is not input in the third input field 73 and the fourth input field 74, the first control unit 10 recognizes that the valid period 83 of the usage right is unlimited (infinite).

  The fifth input field 75 is a field for setting the number of usable times 84 of the protected data 5 to which the right of use is given. In the fifth input field 75, the number (number) is input. The first input device 13 accepts numeric input to the fifth input field 75. When the number of usable times 84 is not input to the fifth input field 75, the first control unit 10 recognizes that the number of times of use is not limited.

  When the setting on the authorization setting screen 7 is completed (when the OK button B1 of the authorization setting screen 7 is operated), the first control unit 10 (first communication device 1) generates the authorization information 8 ((1) Step # 23). Then, the first control unit 10 causes the first communication unit 14 to transmit the authorization information 8 (step # 24). The first control unit 10 transmits the authorization information 8 to the second communication unit 24 (second communication device 2) set on the authorization setting screen 7. The first control unit 10 may encrypt the authorization information 8.

  FIG. 10 shows an example of the authorization information 8. The authorization information 8 includes a reference key 6, an assignment date 81, a protected data name 82, a valid period 83, a usable count 84, and a grant source address 85. The reference key 6 is the reference key 6 attached to the protection data 5 set on the authorization setting screen 7. The assignment date 81 is a creation date of the authorization information 8. The first control unit 10 includes a clock circuit for measuring date and time. The first control unit 10 includes the granting date 81 in the authorization information 8 data. The protected data name 82 is the name of the protected data 5 set on the authorization setting screen 7. The effective period 83 is the effective period 83 of the use authority (authorization information 8) set on the authorization setting screen 7. The usable number of times 84 is the number of times the job can be executed using the protected data 5 set on the authorization setting screen 7. The assignment source address 85 is an address of the first communication device 1. The grant source address 85 is, for example, an electronic mail address. The grant source address 85 may be an address other than an e-mail address.

  When the authorization information 8 is received, the second control unit 20 (second communication device 2) displays an acceptance selection screen on the second display 22 (step # 25). The acceptance selection screen is a screen for selecting whether to receive the authorization for using the protection data 5 or not. The acceptance selection screen includes, for example, a Yes button and a No button. The user operates the Yes button when receiving the right of use. When the user does not receive the right of use, the user operates the No button. The second input device 23 receives a selection as to whether or not to receive the right to use the protected data 5.

  Second control unit 20 (second communication device 2) confirms whether or not an operation for receiving the right of use has been made (step # 26). When an operation for refusing the use authority is performed (No in step # 26 when the No button is operated), the second control unit 20 directs the user to the first communication unit 14 (the first communication device 1). , A rejection response is transmitted (step # 27). Then, the flow ends (end). When the rejection response is transmitted, the second control unit 20 does not store the received authorization information 8 in the second storage unit 21. When the rejection response is received, the first control unit 10 (the first communication device 1) may cause the first display 12 to display the rejection of the authorization. Thereby, the user of the first communication device 1 can recognize the refusal of the usage right.

  When an operation for accepting the grant of the use authority is performed (Yes at step # 26 when the Yes button is operated), the second control unit 20 directs the user to the first communication unit 14 (the first communication device 1). , An acceptance response is sent (step # 28). When the acceptance response is received, the first control unit 10 (first communication device 1) causes the first display 12 to display acceptance of authorization. Thereby, the user of the first communication device 1 can recognize the acceptance of the usage right.

  When the acceptance response is transmitted, the second control unit 20 (second communication device 2) stores the received authorization information 8 in the second storage unit 21 (step # 29, see FIG. 3). Then, the flow ends (end). When the received authorization information 8 is encrypted, the second control unit 20 may store the encrypted authorization information 8 in the second storage unit 21. Further, the second control unit 20 may store the decrypted authorization information 8 in the second storage unit 21.

(Use of protection data 5 based on usage authority)
Next, an example of use of the protection data 5 based on the use authority according to the embodiment will be described with reference to FIGS. 11 and 12. FIG. 11 and FIG. 12 are diagrams showing an example of use of the protection data 5 based on the use authority according to the embodiment.

  The start of FIG. 11 is when the access software 26 is activated by the second communication device 2. The access software 26 is software for using the protection data 5 of another person based on the granted use right. In addition, after unlocking the access software 26, the user of the second communication device 2 can activate the access software 26. Unlocking requires authentication. Fingerprint authentication and password can be used for unlocking. The unlocking method is the same as in the case of FIG. Thereby, unauthorized use of the protection data 5 by a person who does not have the right to use the second communication device 2 can be prevented.

  After authentication of the user, the second input device 23 receives an activation instruction of the access software 26. Thereby, the second control unit 20 (second communication device 2) activates the access software 26. After activation of the access software 26, the second input device 23 receives a selection operation (step # 31). The selection operation is an operation of selecting the authorization information 8 (use authority) to be used among the received authorization information 8 (authorized use authority). For example, the second control unit 20 causes the second display 22 to display a list of the contents of the stored authorization information 8. The user uses the second input device 23 to select the authorization information 8. Based on the output of the second input device 23, the second control unit 20 recognizes the selected authorization information 8. Note that, when there is only one piece of the authorization information 8 stored, step # 31 is skipped. If there is no stored authorization information 8, the second control unit 20 terminates the access software 26.

  When the authorization information 8 is selected, the second control unit 20 (second communication device 2) determines whether or not the number of times the specific protection data has been used in the job is the set number 84 of usable times. Confirm (step # 32). The specific protection data is protection data 5 to which the reference key 6 included in the selected authorization information 8 is attached. In the following description, the protection data 5 to which the reference key 6 included in the received and selected authorization information 8 is attached is referred to as specific protection data.

  The second control unit 20 causes the second storage unit 21 to store the number of times each specific protection data (the protection data 5 to which the use right is given) has been used in the job. The second control unit 20 manages the number of times specific protection data has been used in a job. The second control unit 20 stores the count data 27 in the second storage unit 21 (details will be described later). The count data 27 is data indicating the number of times specific protection data has been used in a job. Based on the number data 27, the second control unit 20 recognizes the number of times the specific protection data corresponding to the selected authorization information 8 has been used in the job.

  When the number of times of use of the specific protection data corresponding to the selected authorization information 8 is less than the set number of usable times 84 (No in step # 32), the second control unit 20 (second communication device 2) The selected authorization information 8 is transmitted to the second communication unit 24 toward the third communication unit 35 (image forming apparatus 3) (step # 33). The image forming device 3 as the transmission destination of the authorization information 8 may be different from the image forming device 3 used for the registration of the protection data 5. The image forming apparatus 3 that receives the authorization information 8 may be the image forming apparatus 3 that can communicate with the data storage device 4.

  When executing a job, it is necessary to perform setting and execution instruction on the operation panel 33 (image forming apparatus 3). Therefore, the second communication device 2 transmits the selected authorization information 8 to the image forming device 3 by near field communication. For example, the second communication device 2 transmits the authorization information 8 to the image forming device 3 by wireless communication of Bluetooth. When the received authorization information 8 is encrypted, the third control unit 30 (image forming apparatus 3) decrypts the encrypted authorization information 8.

  When the authorization information 8 is received, the third control unit 30 (image forming apparatus 3) confirms the valid period 83 included in the authorization information 8. The third control unit 30 confirms whether the received authorization information 8 is within the effective period (step # 34). When it has expired (No in step # 34), the third control unit 30 (image forming apparatus 3) determines whether or not the specific storage data corresponding to the received authorization information 8 is stored in the third storage unit 31. Confirm (step # 35). When not stored (No in step # 35), this flow ends (end). When it is stored (Yes in Step # 35), the third control unit 30 causes the third storage unit 31 to erase the specific protection data corresponding to the received authorization information 8 (Step # 36). Then, the flow ends (end). When the valid period 83 of the use authority has expired, the fourth control unit 40 (image forming apparatus 3) does not execute the job based on the protection data 5 specific protection data.

  When the valid period 83 of the authorization information 8 (use authority) has not expired (Yes in Step # 34), the third control unit 30 receives the authorization information received by the third control unit 30 (image forming apparatus 3). Whether or not the specific protection data corresponding to 8 is stored is confirmed (step # 37).

  When not stored (No in step # 37), the third control unit 30 (image forming apparatus 3) calls the specific protection data (step # 38). Specifically, the third control unit 30 establishes communication with the fourth communication unit 32 (data storage device 4). Then, the third control unit 30 causes the third communication unit 35 to transmit the reference key 6 of the received authorization information 8 toward the fourth communication unit 32. The fourth control unit 40 causes the fourth communication unit 32 to transmit the protection data 5 (specific protection data) to which the received reference key 6 is added, toward the third communication unit 35. The third control unit 30 (image forming apparatus 3) causes the third communication unit 35 to acquire the specific protection data from the data storage device 4. Then, the third control unit 30 stores the acquired specific protection data in the third storage unit 31 in a non-volatile manner (step # 39).

  In the case of Yes in step # 37, or after step # 39, the user inputs settings relating to the job to the operation panel 33. For example, the user sets print jobs based on the specific protection data. After setting is complete, the user instructs to execute the job. The operation panel 33 receives a job execution instruction. When an execution instruction is issued, the control unit starts a job based on the called specific protection data (step # 310).

  When the job is executed, the third control unit 30 (image forming apparatus 3) generates image data (bitmap data) used for the job based on the specific protection data. For example, when printing, the third control unit 30 (image forming apparatus 3) generates image data for printing based on the specific protection data. The third control unit 30 causes the printing unit 34 to perform printing based on the generated image data. When the processing is completed up to the last page, the job is completed (step # 311).

  When the job is completed, the third control unit 30 (image forming apparatus 3) transmits a job completion notification to the third communication unit 35 toward the second communication unit 24 (second communication apparatus 2) (step #). 312). The third control unit 30 includes at least the reference key 6 in the job completion notification. The third control unit 30 adds the reference key 6 of the specific protection data used for the executed job to the job completion notification. The third control unit 30 may add the authorization information 8 corresponding to the specific protection data used for the job to the job completion notification.

  When receiving the job completion notification, the second control unit 20 (second communication device 2) counts up the value of the number of times the specific protection data has been used in the job (step # 313). For example, the second control unit 20 stores data in which the received reference key 6 is associated with the number of times of use as the number data 27 in the second storage unit 21. When the specific protected data is used for the first time in the job, the second control unit 20 newly stores the new count data 27 in the second storage unit 21. The value of the number of times used in the number of times data 27 is one. The second control unit 20 extracts the count data 27 including the same reference key 6 as the received reference key 6 for the specific protection data used in the job before. Then, the second control unit 20 adds 1 to the value of the used number of times of the extracted number data 27.

  Then, the second control unit 20 (second communication device 2) causes the second communication unit 24 to transmit a use notification (step # 314). The second control unit 20 transmits a use notification to the first communication unit 14 (the first communication device 1) to which the use authority of the specific protection data used in the job is given. The address (granting source address 85) of the first communication device 1 to which the usage right has been granted is included in the authorization information 8. The use notification may be transmitted to the first communication apparatus 1 to which the image forming apparatus 3 (third control unit 30) has given the use authority. The second control unit 20 or the third control unit 30 adds the reference key 6 to the use notification.

  When receiving the use notification, the first control unit 10 (first communication device 1) causes the first display 12 to display information on the used specific protection data (step # 315). For example, the first control unit 10 causes the first display 12 to display the content of the protected data information 19 in which the reference key 6 matches. It is possible to notify the person who has given the use authority that the own protection data 5 has been used for the job. Then, the flow ends (end).

  On the other hand, when the number of times of use of the specific protection data corresponding to the selected authorization information 8 is the set number of usable times 84 (Yes in step # 32), the second control unit 20 (second communication device 2) ) Sends the deletion instruction to the second communication unit 24 toward the third communication unit 35 (image forming apparatus 3) (step # 316). For example, the second control unit 20 includes the reference key 6 of the selected authorization information 8 in the deletion instruction. After transmitting the deletion instruction, second control unit 20 causes second storage unit 21 to delete the selected authorization information 8 (step # 317).

  When the deletion instruction is received, third control unit 30 (image forming apparatus 3) confirms whether or not protection data 5 including received reference key 6 is stored in third storage unit 31 (step # 318). ). When not stored (No in step # 318), this flow ends (end). When it is stored (Yes in step # 318), third control unit 30 causes third storage unit 31 to erase protected data 5 including reference key 6 attached to the received deletion instruction (step # 319). . Then, the flow ends (end). That is, the third control unit 30 (image forming apparatus 3) does not execute the job based on the protected data 5 whose number of times of use has reached the upper limit.

  Thus, the image forming system 100 according to the embodiment includes the first communication device 1, the second communication device 2, and the image forming device 3.

The second communication device 2 stores the received authorization information 8. The second communication device 2 transmits the received authorization information 8 to the image forming device 3. When the image forming apparatus 3 receives the authorization information 8 transmitted from the second communication device 2, the image forming apparatus 3 calls the specific protection data which is the protection data 5 to which the reference key 6 included in the received authorization information 8 is added. . The image forming apparatus 3 receives a job execution instruction based on the called specific protection data. When the execution instruction is received, the image forming apparatus 3 executes a job based on the specific protection data. Thereby, the holder of the second communication device 2 can use the specific protection data. A person who creates the protection data 5 can perform a job using the specific protection data.

  The first communication device 1 receives the setting of the valid period 83 of the authorization information 8. The first communication device 1 transmits the authorization information 8 including the set valid period 83 to the second communication device 2 set by the assignment operation. When the valid period 83 of the received authorization information 8 has not passed, the image forming apparatus 3 executes a job based on the specific protection data. When the valid period 83 of the received authorization information 8 has passed, the image forming apparatus 3 does not execute the job based on the specific protection data. Thereby, the holder of the second communication device 2 can use the specific protection data only during a period desired by the registrant (creator) of the protection data 5. It is possible to prohibit a job using protection data 5 in a period in which the registrant does not permit.

  The image forming apparatus 3 erases the protected data 5 with the reference key 6 included in the authorization information 8 whose validity period 83 has expired. As a result, the protected data 5 that can not be used by the holder of the second communication device 2 can be automatically erased. The storage area of the image forming apparatus 3 can be prevented from being compressed by the protection data 5 which can not be used.

  The first communication device 1 receives the setting of the number of usable times 84 of the specific protection data. The first communication device 1 transmits the authorization information 8 including the usable number 84 to the second communication device 2 set by the assignment operation. The second communication device 2 stores, for each piece of the authorization information 8 to be stored, the number of times the specific protection data has been used in the job. The second communication device 2 transmits, to the image forming device 3, the authorization information 8 corresponding to the specific protected data whose number of times of use is less than the number of usable times 84. The second communication device 2 does not transmit, to the image forming device 3, the authorization information 8 corresponding to the specific protection data in which the number of times of use has reached the number of usable times 84. Thereby, the holder of the second communication device 2 can use the specific protection data as many times as the creator of the data desires. The number of jobs using specific protection data can be made up to the number permitted by the creator of the specific protection data.

  The image forming apparatus 3 erases the protected data 5 for which the number of times of use has reached the usable number of times 84. As a result, the protected data 5 that can not be used by the holder of the second communication device 2 can be automatically erased. The storage area of the image forming apparatus 3 can be prevented from being compressed by the protection data 5 which is not used.

  When the job based on the specific protected data is executed, the image forming apparatus 3 or the second communication apparatus 2 sends the job based on the specific protected data to the first communication apparatus 1 to which the use right of the specific protected data used in the job is given. To notify that was done. This makes it possible to notify the registrant (creator) of the specific protection data that the job based on the specific protection data has been performed. When notified at an unexpected timing, the creator notices that an unauthorized job based on the specific protection data has been performed.

  The imaging system 100 includes a data storage device 4 in communication with the first communication device 1 and the imaging device 3. The first communication device 1 receives a protection operation which is an operation for storing the document data 18 as the protection data 5. The first communication device 1 transmits the document data 18 for which the protection operation has been performed to the data storage device 4. When the data storage device 4 receives the document data 18 for which the protection operation has been performed, the data storage device 4 generates the reference key 6. The data storage device 4 stores the document data 18 with the generated reference key 6 as the protected data 5. When the protected data 5 is stored, the data storage device 4 transmits the protected data information 19 including the reference key 6 to the first communication device 1. The first communication device 1 stores the received protected data information 19. Thereby, the document data 18 attached with the reference key 6 can be registered as the protection data 5. Image forming device 3 communicates with data storage device 4.
