Description

The present invention relates to an information processing system, an information processing device, an information processing method, and a program.

In recent years, by opening a Web API (Application Programming Interface) for utilizing various functions of the image forming apparatus, an application installed in the image forming apparatus has been developed by a third vendor or the like. In such a case, an authentication token (development token) for the application under development to use the WebAPI is issued to the third vendor by the manufacturer of the image forming apparatus. As a result, a third vendor or the like can develop an application by using the development token and the WebAPI of the image forming apparatus used for the development.

<Functional configuration>
Next, the functional configuration of the information processing system 1 according to the present embodiment will be described with reference to FIG. FIG. 4 is a diagram showing a functional configuration of an example of the information processing system 1 according to the present embodiment.

As shown in FIG. 4, the terminal device 10 according to the present embodiment has a browser 11 executed by the CPU 106 or the like, for example. The user of the terminal device 10 can use the browser 11 to execute the development application 21 described later (that is, for example, confirm the operation of the development application 21).

The terminal device 10 also has a token storage unit 12. The token storage unit 12 can be realized by using the HDD 108, for example. The token storage unit 12 stores a development or product token 12D issued by the manufacturer of the image forming apparatus 30. The user of the terminal device 10 can receive the service using the various functions of the image forming apparatus 30 by the application by transmitting a request including the token 12D to the application via the browser 11.

Here, the token 12D stored in the token storage unit 12 will be described with reference to FIG. FIG. 5 is a diagram showing an example of a token.

As shown in FIG. 5, the token 12D has a token value, an expiration date, a type flag, and the like. A value indicating a character string or the like used for authentication is set as the token value. The expiration date is set to a value indicating the expiration date when the token value can be used for authentication. In the type flag, a value indicating whether the type of the token 12D is for development or for product is set.

Here, the development token is an authentication token for an application under development (that is, the development application 21) to use various functions of the image forming apparatus 30. On the other hand, the product token is an authentication token for an application whose development has been completed (that is, a product application released as a product, for example) to use various functions of the image forming apparatus 30.

The development token includes a token used for evaluation of the development application 21 (for example, operation test) (so-called evaluation token). Therefore, the names “development token” and “product token” are for convenience and are not limited to these names.

As shown in FIG. 4, the server device 20 according to the present embodiment has a development application 21 executed by, for example, the CPU 106 or the like. The development application 21 is an application program that provides services using various functions of the image forming apparatus 30, and is under development by a third vendor or the like.

As shown in FIG. 4, the image forming apparatus 30 according to the present exemplary embodiment includes an application group 31 that provides services using various functions of the image forming apparatus 30. When the development of the development application 21 is completed, the product application 22 is installed by being downloaded from the server device 20 to the image forming device 30, for example. The application group 31 includes various applications such as a copy application that provides a copy service using the copy function of the image forming apparatus 30 and a print application that provides a print service using the print function. However, the application group 31 is not limited to the case where a plurality of applications are included, and may include one or more applications.

The image forming apparatus 30 also includes a WebAPI 32, a determination processing unit 33, a function execution unit 34, a device token management unit 35, and a table updating unit 36. Each of these functional units is realized by a process executed by the CPU 211 by one or more programs installed in the image forming apparatus 30.

Further, the image forming apparatus 30 includes a determination table storage unit 41, a device information storage unit 42, and a device token storage unit 43. Each of these storage units can be realized by using the HDD 215, for example. Note that at least one of these storage units may be realized by a storage device or the like connected to the image forming apparatus 30 via a network.

The WebAPI 32 is an API for each application included in the development application 21 and the application group 31 to use various functions of the image forming apparatus 30. The development application 21 and the like can use various functions of the image forming apparatus 30 (for example, a scan function and a FAX communication function) by making various requests to the WebAPI 32 in the form of an HTTP (Hypertext Transfer Protocol) request. ..

That is, for example, the development application 21 transmits the HTTP request to the WebAPI 32 by using the token 12D included in the HTTP request received from the browser 11. Accordingly, when the determination processing unit 33 described below determines that the token 12D is valid, the development application 21 can use various functions of the image forming apparatus 30.

The determination processing unit 33 determines whether or not the token 12D included in the request received from the development application 21 or the like via the WebAPI 32 can be used. Here, the determination processing unit 33 includes a device identification unit 51, a token identification unit 52, a validity determination unit 53, and a registration determination unit 54.

The device identifying unit 51 acquires the device information 42D from the device information storage unit 42 and identifies the type of the image forming apparatus 30 from the device information 42D. The types of the image forming apparatus 30 include a “development version” indicating that the device is used for checking the operation of the development application 21 (that is, a device for testing, for example), and a device that is sold or leased as a product. There is a "commercial version" that indicates that

The token identification unit 52 identifies the type of the token 12D. As described above, the types of the token 12D include “for development” indicating that the token is used by the development application 21 and “for product” indicating that the token is used by the product application 22.

The validity determination unit 53 acquires the information (value) of the determination table 41D from the determination table storage unit 41. The validity determining unit 53 then acquires the information (value) of the acquired determination table 41D, the type of the image forming apparatus 30 identified by the device identifying unit 51, and the type of the token 12D identified by the token identifying unit 52. Based on the above, the validity of the token 12D is determined.

For example, when the development application 21 uses the product token 12D to request the use of various functions of the development version image forming apparatus 30, the validity determination unit 53 determines that the token 12D is invalid. Further, for example, when the development application 21 uses the development token 12D to request the use of various functions of the product version image forming apparatus 30, the validity determination unit 53 determines that the token 12D is invalid. To do.

When the validity determination unit 53 determines that the token 12D is valid, the determination processing unit 33 determines that the token 12D can be used.

In this way, by determining the validity of the token 12D by the validity determination unit 53, for example, it is possible to prevent the situation where various functions of the development version image forming apparatus 30 are used by using the product token 12D. can do.

When the validity determination unit 53 determines that the token 12D is invalid, the registration determination unit 54 determines whether the device token 43D corresponding to the token 12D is stored in the device token storage unit 43.

Here, the device token 43D is a token that has the same token value as the development token 12D and is registered in the image forming apparatus 30. Therefore, the registration determination unit 54 determines whether the device token 43D having the same token value as the token 12D determined to be invalid by the validity determination unit 53 is registered in the image forming apparatus 30.

When the registration determination unit 54 determines that the device token 43D corresponding to the token 12D is stored in the device token storage unit 43, the determination processing unit 33 determines that the token 12D can be used. On the other hand, when the registration determination unit 54 determines that the device token 43D corresponding to the token 12D is not stored in the device token storage unit 43, the determination processing unit 33 determines that the token 12D is unavailable. ..

In this way, even if the token 12D is determined to be invalid by the validity determining unit 53, if the device token 43D corresponding to the token 12D is registered in the image forming apparatus 30, the determination processing unit 33. Determines that the token 12D is available. Therefore, for example, it is possible to prevent the situation where various functions of the product version of the image forming apparatus 30 are used by using the development token 12D, and by registering the device token 43D, the development token 12D is used. By using the token 12D, various functions of the product version image forming apparatus 30 can be used.

Therefore, for example, the developer of the development application 21 uses the development token 12D to perform a test using each function of the product version image forming apparatus 30 (an operation test assuming that the product is released as a product). You will be able to do it.

The function execution unit 34 executes various functions of the image forming apparatus 30 according to the determination result of the determination processing unit 33.

The device token management unit 35 registers and updates the device token 43D. For example, the device token management unit 35 registers the device token 43D by storing the device token 43D in the device token storage unit 43. Further, for example, the device token management unit 35 updates the device token 43D by editing the device token 43D stored in the device token storage unit 43. The device token 43D is registered, updated, or the like, for example, by the vendor of the manufacturer of the image forming apparatus 30 in response to a request from a third vendor who develops the development application 21.

The table updating unit 36 updates the determination table 41D stored in the determination table storage unit 41. For example, the table updating unit 36 updates the determination table 41D by editing the information (value) of the determination table 41D stored in the determination table storage unit 41. The determination table 41D is updated by, for example, the vendor of the manufacturer of the image forming apparatus 30 in response to a request from a third vendor who develops the development application 21.

The determination table storage unit 41 stores the determination table 41D. Here, the judgment table 41D stored in the judgment table storage unit 41 will be described with reference to FIG. FIG. 6 is a diagram showing an example of the determination table 41D.

As illustrated in FIG. 6, the determination table 41D is associated with information (value) indicating whether the token 12D is valid or invalid according to the combination of the type of the image forming apparatus 30 and the type of the token 12D.

For example, in the determination table 41D illustrated in FIG. 6, when the type of the image forming apparatus 30 is “development version” and the type of the token 12D is “for development”, it is determined that the token 12D is valid. “Valid” is associated. Similarly, for example, in the determination table 41D illustrated in FIG. 6, when the type of the image forming apparatus 30 is “product version” and the type of the token 12D is “development”, the token 12D is determined to be invalid. “Invalid” indicating is associated.

The device information storage unit 42 stores the device information 42D including various kinds of information regarding the image forming apparatus 30. Here, the device information 42D stored in the device information storage unit 42 will be described with reference to FIG. 7. FIG. 7 is a diagram showing an example of the device information 42D.

As shown in FIG. 7, the device information 42D has a serial number, a version, and the like. A value indicating identification information (for example, a manufacturer's unique number) that uniquely identifies the image forming apparatus 30 is set in the serial number. A value indicating the version number of the image forming apparatus 30 is set in the version. In addition to these, the device information 42D may include various information such as performance information of the image forming apparatus 30.

The device token storage unit 43 stores the device token 43D. Note that the device token storage unit 43 may store a plurality of device tokens 43D.

Here, the device token 43D stored in the device token storage unit 43 will be described with reference to FIG. FIG. 8 is a diagram showing an example of the device token 43D.

As shown in FIG. 8, the device token 43D has a token value, an expiration date, and the like. A value indicating a character string or the like used for authentication is set as the token value. The expiration date is set to a value indicating the expiration date when the token value can be used for authentication.

<Details of processing>
Next, details of the processing of the information processing system 1 according to the present embodiment will be described. First, a case where the user of the terminal device 10 (the developer of the development application 21 or the like) executes the development application 21 to confirm the operation of the development application 21 will be described with reference to FIG. 9. FIG. 9 is a sequence diagram showing an example of execution processing of the development application.

First, the user operates the browser 11 of the terminal device 10 to perform an operation for executing the development application 21. Then, the browser 11 of the terminal device 10 transmits an application execution request to the development application 21 of the server device 20 (step S901). Here, the execution request includes the token 12D. The browser 11 transmits an application execution request in the HTTP request format.

Upon receiving the application execution request, the development application 21 of the server device 20 transmits the request API to the Web API 32 of the image forming apparatus 30 (step S902). Here, the request API is a request for using a predetermined function of the image forming apparatus 30, and includes the token 12D. The development application 21 transmits the request API in the HTTP request format.

Upon receiving the request API, the Web API 32 of the image forming apparatus 30 transmits a request for determining whether or not the token 12D included in the request API can be used to the determination processing unit 33 (step S903).

When the determination processing unit 33 of the image forming apparatus 30 receives the availability determination request, the determination processing unit 33 executes the token availability determination processing (step S904). That is, the determination processing unit 33 determines whether the token 12D included in the request API can be used. The details of the token availability determination process will be described later.

Here, when it is determined in step S904 that the token 12D is not available (that is, it is determined that the token 12D is unavailable), the processes of steps S905 to S907 are executed. That is, first, the determination processing unit 33 of the image forming apparatus 30 transmits a determination result indicating that the token 12D included in the request API is unavailable to the WebAPI 32 (step S905).

Next, when the WebAPI 32 of the image forming apparatus 30 receives the determination result indicating that the token 12D is unavailable, the WebAPI 32 transmits a response API indicating that the token 12D is unavailable to the development application 21 (step S906). ..

Lastly, when the development application 21 of the server device 20 receives the response API indicating that the token 12D is unavailable, the development application 21 transmits an application execution response indicating that the token 12D is unavailable to the browser 11 (step S907). As a result, on the display device 102 of the terminal device 10, the browser 11 displays, for example, a notification indicating that the image forming apparatus 30 cannot be accessed.

On the other hand, when it is determined in step S904 that the token 12D is available, the processes of steps S908 to S912 are executed. That is, first, the determination processing unit 33 of the image forming apparatus 30 transmits an execution request for the function corresponding to the request API to the function execution unit 34 (step S908).

Next, upon receiving the function execution request, the function execution unit 34 of the image forming apparatus 30 executes the function corresponding to the execution request (step S909). That is, the function execution unit 34 executes various functions of the image forming apparatus 30, such as a scan function, a copy function, and a FAX communication function, in response to a function execution request.

Next, the function execution unit 34 of the image forming apparatus 30 transmits the execution result of the function executed in step S909 to the WebAPI 32 (step S910). The function execution result is, for example, image data generated by reading a document by the scan function when the scan function is executed in step S909.

Next, the WebAPI 32 of the image forming apparatus 30 transmits the response API including the execution result of the function to the development application 21 (step S911).

Finally, when the development application 21 of the server device 20 receives the response API including the execution result of the function, for example, after executing the process based on the execution result, the development application 21 displays the execution response of the application including the process result of the process. It is transmitted to the browser 11 (step S912). Note that the processing executed here is processing unique to the development application 21, and is, for example, processing processing of image data generated by the scan function.

Thereby, on the display device 102 of the terminal device 10, the browser 11 displays, for example, a processing result by the development application 21. That is, the development application 21 provides the user of the terminal device 10 with services using various functions of the image forming apparatus 30.

Note that, although the case where the development application 21 uses various functions of the image forming apparatus 30 has been described with reference to FIG. 9, the present invention is not limited to this. For example, when the product application 22 uses various functions of the image forming apparatus 30. It can be applied similarly. That is, for example, the same can be applied to the case where the product application 22 installed in the image forming apparatus 30 or the terminal device 10 transmits the request API.

Here, the details of the token availability determination process in step S904 will be described below with reference to FIG. FIG. 10 is a flowchart showing an example of the token availability determination process.

First, the device identifying unit 51 of the determination processing unit 33 acquires the device information 42D from the device information storage unit 42 (step S1001).

Next, the device identifying unit 51 of the determination processing unit 33 identifies the type of the image forming apparatus 30 from the device information 42D acquired in step S1001 (step S1002).

Here, the device identifying unit 51 identifies the type of the image forming device 30 based on the serial number and the version included in the device information 42D (that is, the image forming device 30 is a "development version" or a "production version"). Specify which one).

That is, the device identifying unit 51 identifies the image forming device 30 as a “development version”, for example, when a value is not set for the serial number of the device information 42D or when a null value (NULL value) is set. .. On the other hand, for example, when a value other than a null value is set in the serial number of the device information 42D, the device identifying unit 51 identifies the image forming device 30 as a “product version”.

In addition, the device identifying unit 51 identifies whether the image forming apparatus 30 is the “development version” or the “production version”, for example, according to the value set in the serial number of the device information 42D. good. Specifically, when a predetermined character (for example, "Z") is designated as the most significant digit of the value set in the serial number of the device information 42D, the image forming apparatus 30 is set to "development version". Specify. On the other hand, when a character other than the predetermined character is specified in the most significant digit of the value set in the serial number of the device information 42D, the image forming apparatus 30 is identified as the "product version".

In addition, the device specifying unit 51 may specify whether the image forming apparatus 30 is a “development version” or a “production version”, for example, according to the value set in the version of the device information 42D. .. Specifically, when the value set for the version of the device information 42D is less than 1 (that is, "0.12", for example), the image forming apparatus 30 is specified as the "development version". On the other hand, when the value set in the version of the device information 42D is 1 or more (that is, "1.00", for example), the image forming apparatus 30 is specified as the "product version".

In this way, the device identification unit 51 identifies the type of the image forming apparatus 30 based on various information such as the serial number and version included in the device information 42D.

Next, the token identification unit 52 of the determination processing unit 33 identifies the type of the token 12D included in the request API received by the WebAPI 32 (step S1003). That is, for example, when the value set in the type flag of the token 12D is “1”, the token identification unit 52 identifies the token 12D as “for product”. On the other hand, for example, when the value set in the type flag of the token 12D is “0”, the token identification unit 52 identifies the token 12D as “for development”.

In addition, the token identification unit 52 may identify the type of the token 12D, for example, depending on whether or not the predetermined information included only in the product token 12D is included in the corresponding token 12D.

In this way, the token identification unit 52 identifies the type of the token 12D based on various information such as the type flag included in the token 12D.

Next, the validity determination unit 53 of the determination processing unit 33 acquires the information of the determination table 41D from the determination table storage unit 41 (step S1004).

Subsequently, the validity determination unit 53 of the determination processing unit 33, among the information of the determination table 41D acquired in step S1004, information (value) corresponding to the combination of the type of the image forming apparatus 30 and the type of the token 12D. Is acquired (step S1005).

That is, for example, the validity determination unit 53 corresponds to the combination of the type of the image forming apparatus 30 identified in step S1002 and the type of the token 12D identified in step S1003 in the information (value) of the determination table 41D. Obtaining Value (“Valid” or “Invalid”) Next, the validity determination unit 53 determines whether the token 12D is valid based on the value obtained in step S1005 (step S1006). That is, the validity determination unit 53 determines that the token 12D is valid when the value acquired in step S1005 is “valid”. On the other hand, the validity determining unit 53 determines that the token 12D is not valid (that is, invalid) when the value acquired in step S1005 is “invalid”.

In step S1006 described above, the validity determination unit 53 determines that the token 12D is invalid when the expiration date included in the token 12D has elapsed.

When the validity determination unit 53 determines that the token 12D is invalid in step S1006, the registration determination unit 54 determines whether the device token 43D corresponding to the token 12D is registered in the image forming apparatus 30. The determination is made (step S1007). That is, the registration determination unit 54 determines whether or not the device token 43D having the same token value as the token value included in the token 12D is stored in the device token storage unit 43.

In step S1007, when the registration determination unit 54 determines that the device token 43D is not registered, the determination processing unit 33 determines that the token 12D is unavailable (step S1008). In this way, the determination processing unit 33 determines that the token 12D cannot be used when the token 12D is invalid and the device token 43D corresponding to the token 12D is not registered.

On the other hand, when the validity determination unit 53 determines that the token 12D is valid in step S1006, the determination processing unit 33 determines that the token 12D is available. Similarly, when the registration determination unit 54 determines that the device token 43D is registered in step S1007, the determination processing unit 33 determines that the token 12D is available (step S1009). In this way, the determination processing unit 33 can use the token 12D when the token 12D is valid and when the device token 43D corresponding to the token 12D is registered even if the token 12D is invalid. It is determined that In other words, when the device token 43D corresponding to the token 12D is registered in the image forming apparatus 30, the determination processing unit 33 determines that the token 12D can be used.

As described above, in the information processing system 1 according to the present embodiment, the validity of the token 12D is determined according to the combination of the type of the image forming apparatus 30 and the type of the token 12D. Then, in the information processing system 1 according to the present embodiment, when it is determined that the token 12D is valid, it is determined that the token 12D can be used.

Further, in the information processing system 1 according to the present embodiment, even when it is determined that the token 12D is invalid, if the device token 43D corresponding to the token 12D is registered in the image forming apparatus 30. , Determine that the token 12D is available.

In addition, the device token management unit 35 deletes the selected device token 43D when the deletion operation of the device token 43D is received.

As described above, the information processing system 1 according to the present embodiment can update the device token 43D registered in the image forming apparatus 30. Thereby, for example, the expiration date of the development token 12D has passed, while the expiration date of the device token 43D has not passed. Therefore, for example, in the operation test stage of the development application 21, the development application 21 prevents the development version of the image forming apparatus 30 from being used, while the production version of the image forming apparatus 30 is available. You can

In addition, the information processing system 1 according to the present embodiment can delete the device token 43D registered in the image forming apparatus 30. Thereby, for example, the device token 43D registered in the image forming apparatus 30 can be deleted when the operation test of the development application 21 is stopped or when the operation test ends earlier than planned. ..

Here, the development application 21 uses the product version of the image forming apparatus 30 by using the development token 12D even when the person in charge such as the manufacturer of the image forming apparatus 30 updates the information in the determination table 41D. Will be able to. Therefore, hereinafter, a case of updating the information of the determination table 41D stored in the determination table storage unit 41 will be described with reference to FIG. FIG. 16 is a diagram illustrating an example of a determination table update process.

First, the table updating unit 36 displays the edit screen G310 of the determination table shown in FIG. 17, for example (step S1601).

The determination table editing screen G310 shown in FIG. 17 is a screen for a person in charge such as the manufacturer of the image forming apparatus 30 to edit each information in the determination table 41D. The edit screen G310 of the determination table shown in FIG. 17 includes a table edit column G311 in which each information of the determination table 41D is displayed in an editable manner, and an expiration date column G313 for setting the expiration date of the updated determination table 41D. , OK button G314.

A person in charge of the manufacturer of the image forming apparatus 30 can edit each piece of information in the determination table 41D from the table edit column G311 in response to a request from a developer such as a third vendor who develops the development application 21. .. For example, when a person in charge such as a manufacturer vendor wants to edit the information in the determination table 41D when the type of the image forming apparatus 30 is “product version” and the type of the token 12D is “for product”, he/she wants from the pull-down G312. Select a value.

In this way, the person in charge such as the manufacturer vendor selects the information to be edited in the determination table 41D in the table edit column G311, and then selects the edited information (value) from the pull-down menu. Then, the person in charge such as the manufacturer vendor presses the OK button G314. Thereby, the person in charge such as the manufacturer vendor can perform the update operation of the determination table 41D.

The table updating unit 36 may display the edit screen G310 of the determination table shown in FIG. 17 on the operation panel 202 of the image forming apparatus 30, or information connected to the image forming apparatus 30 via the network. It may be displayed on a processing terminal or the like.

Here, the person in charge such as the manufacturer vendor may input the expiration date of the updated determination table 41D in the expiration date column G313. As a result, when the expiration date entered in the expiration date column G313 has passed, the information in the determination table 41D is updated by the table updating unit 36 to the state before the update. That is, the person in charge such as the manufacturer vendor can temporarily update each information in the determination table 41D by inputting the expiration date in the expiration date field G313.

Next, when the table updating unit 36 receives the update operation of the determination table 41D, the table updating unit 36 updates each information of the determination table 41D stored in the determination table storage unit 41 (step S1602).

As described above, the information processing system 1 according to the present embodiment can update each information in the determination table 41D. Thereby, for example, each information of the determination table 41D stored in the determination table storage unit 41 can be set to "valid" only during the operation test of the development application 21. Therefore, in an operation test or the like of the development application 21, the development application 21 can use the product version of the image forming apparatus 30 by using the development token 12D.

[Second embodiment]
Next, a second embodiment will be described. The second embodiment is different from the first embodiment in that the token 13D including information for determining whether or not the token is available is stored in the token storage unit 12 of the terminal device 10. In addition, in the second embodiment, the same reference numerals as those in the first embodiment are given to the parts having the same functional configurations and the parts performing the same processing as those in the first embodiment, and the description thereof will be omitted. ..

<Functional configuration>
First, the functional configuration of the information processing system 1 according to the second embodiment will be described with reference to FIG. FIG. 18 is a diagram showing a functional configuration of an example of the information processing system 1 according to the second embodiment.

As shown in FIG. 18, the token storage unit 12 of the terminal device 10 stores a token 13D.

Here, the token 13D stored in the token storage unit 12 will be described with reference to FIG. FIG. 19 is a diagram showing an example of a token.

As shown in FIG. 19, the token 13D further includes usage permission information. As the use permission information, for example, "true" indicating that the token 12D is available, "false" indicating that the token 12D is unavailable, and the like are set. The usage permission information may be, for example, the serial number of the image forming apparatus 30.

The token 13D is provided by the manufacturer vendor or the like in response to a request from the third vendor or the like. That is, for example, a developer such as a third vendor can receive the token 13D in which the usage permission information is added to the token 12D by sending the token 12D to the manufacturer vendor.

As illustrated in FIG. 18, the determination processing unit 33 of the image forming apparatus 30 includes a usage permission determination unit 55. When the validity determination unit 53 determines that the token 12D is invalid, the usage permission determination unit 55 determines whether the usage permission information included in the token 12D is “true”.

When the usage permission information is the serial number of the image forming apparatus 30, the usage permission determination unit 55 determines whether it matches the serial number included in the device information 42D stored in the device information storage unit 42. Just do it.

<Details of processing>
Next, details of the processing of the information processing system 1 according to the present embodiment will be described. Hereinafter, details of the token availability determination process in step S904 of FIG. 9 will be described with reference to FIG. FIG. 20 is a flowchart showing an example of the token availability determination process. It should be noted that the processing of steps S1001 to S1006 of FIG. 20 is the same as that of the first embodiment by replacing “token 12D” with “token 13D”, and therefore description thereof will be omitted.

In step S1006, when the validity determination unit 53 determines that the token 13D is invalid, the usage permission determination unit 55 determines whether the usage permission information included in the token 13D is “true”. (Step S2001).

When the usage permission information included in the token 13D is the serial number of the image forming apparatus 30, the usage permission determination unit 55 matches the serial number included in the device information 42D stored in the device information storage unit 42. It is determined whether to do.

In step S2001, when the usage permission determination unit 55 determines that the usage permission information is not “true” (or when the serial numbers do not match), the determination processing unit 33 cannot use the token 13D. (Step S2002). In this way, the determination processing unit 33 determines that the token 13D is unusable if the token 13D is invalid and the usage permission information included in the token 13D is not “true”.

On the other hand, when the validity determination unit 53 determines that the token 13D is valid in step S1006, the determination processing unit 33 determines that the token 13D is available. Similarly, in step S2001, when the usage permission determination unit 55 determines that the usage permission information is “true” (or when the serial numbers match each other), the determination processing unit 33 uses the token 13D. It is determined that it is possible (step S2003). As described above, the determination processing unit 33 determines whether the usage permission information included in the token 13D is “true” (or the serial number of the image forming apparatus 30 matches) even if the token 13D is invalid. It is determined that the token 12D can be used.

As described above, in the information processing system 1 according to the present embodiment, even when it is determined that the token 13D is invalid, predetermined information is set in the usage permission information included in the token 13D. In this case, it is determined that the token 13D can be used. Thereby, in the information processing system 1 according to the present embodiment, for example, when an operation test of the development application 21 is desired, a developer such as a third vendor may obtain the token 13D from the manufacturer vendor. ..

Although the embodiments of the present invention have been described above in detail, the present invention is not limited to such specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims. -Can be changed.
