[Overview]
In recent years, mobile terminals such as multifunctional mobile phones (hereinafter referred to as "smartphones") and tablet-type mobile terminals are rapidly becoming widespread. With the spread of mobile terminals, there are an increasing number of use cases in which a plurality of users share and use one mobile terminal. When multiple users share and use one mobile terminal, from the viewpoint of information security, granting access rights to image data stored in the mobile terminal and permitting / disallowing functions such as viewing / editing are determined for each user. It is desired to switch to.

The OS mounted on the mobile terminal supports a multi-user mode that is assumed to be used by a plurality of users in recent years. In the multi-user mode, an account is issued for each user in order to identify the user, and the mobile terminal gives an access right to the image data stored in the mobile terminal and allows or disallows functions such as viewing / editing. It is managed every time. In addition, the smartphone uses a SIM card ID (IMSI: international mobile subscriber identification number) as information for identifying the user. Conventionally, various functions of the mobile terminal have been enabled only when a SIM card having a specific SIM card ID is mounted. However, in recent years, this restriction has been lifted (SIM-free), and it has become possible to enable mobile terminals regardless of the type of SIM card. A SIM-free mobile terminal can be used as a mobile terminal in which a plurality of users can share and use one mobile terminal by replacing the SIM card.

As information for identifying a user who uses a smartphone, there is a UUID generated in a specific application on a mobile terminal. Although the UUID is limited to use within the application, the mobile terminal can generate a UUID uniquely determined for each user and manage the user information using the UUID as the user information. The mobile terminal switches the permission of the function such as granting the access right to the image data stored in the mobile terminal and viewing / editing according to the UUID. As a result, information security can be ensured even if one mobile terminal is shared and reused by a plurality of users.

In the present invention, the account information of the plurality of user modes (for example, a user ID that is not highly confidential), the SIM card ID information, the UUID information, and the like as described above are used to execute the authentication printing as the user information. As a result, even when a plurality of users share and use one mobile terminal, authentication can be easily performed for each user, and highly secure authentication printing can be realized.

As described above, in the prior art, the text management server is configured to perform authentication printing when only the terminal individual identifier of the mobile terminal is authenticated. In the present invention, assuming that a plurality of users share and use one mobile terminal, authentication printing is performed when user information is also authenticated in addition to the terminal individual identifier of the mobile terminal.

In the embodiment of the present invention, account information in a plurality of user modes, SIM card ID information, UUID information, and the like are exemplified as user information. These user information are not uniquely determined identification information in the world, and each of them may be duplicated. Therefore, it is not a desirable form from the viewpoint of information security to configure the authentication printing by authenticating only the user information instead of the terminal individual identifier.

[Embodiment 2]
In the authentication printing system 100 according to the first embodiment, an embodiment in which the image forming apparatus 200 executes the authentication printing process by using the terminal individual identifier of the mobile terminal 400 and the user information in order to execute the printing process has been described.

In the prior art, there is known a printing system in which an image forming apparatus 200 or an authentication server 300 manages a plurality of user information used in an authentication system in advance. In such a printing system, user information is received from a terminal in the printing system (hereinafter referred to as "print instruction terminal"), and when the received user information matches one of the plurality of user information, the image forming apparatus 200 Executes the printing process.

In the authentication printing system 100 according to the second embodiment, the technical idea of the present invention is applied by linking an existing printing system that manages a plurality of user information in advance with the authentication information which is a characteristic configuration of the present invention. An aspect of executing the authentication printing process will be described.

FIG. 21 is a schematic view showing the processing content of the authentication printing process in the present embodiment. First, the control unit of the print instruction terminal 500 transmits the print data to the authentication server 300. For example, it is assumed that the terminal individual identifier is "EE-FFFFFF-GGGGGG-D", the user information is "00000241", the print setting is "Xxxxxxx", and the content information is "AAAAAA.doc". At this time, the control unit of the print instruction terminal 500 transmits the print data composed of the terminal individual identifier, the user information, the print setting, and the content information to the authentication server 300 (A. print data transmission process). .. The print instruction terminal 500 is a terminal different from the mobile terminal 400 described later, and corresponds to the "first print instruction terminal" in the scope of claims.

The control unit 321 of the authentication server 300 receives print data including the terminal individual identifier "EE-FFFFFF-GGGGGG-D", the user information "00000241", the print setting "Xxxxxxx", and the content information "AAAAA.doc". The print data management unit 324 of the authentication server 300 stores the print data in the print data management table 330 (FIG. 12).

Next, the control unit 221 of the image forming apparatus 200 transmits the authentication information received from the mobile terminal 400 to the authentication server 300. For example, it is assumed that the terminal individual identifier is "AA-BBBBBB-CCCCCC-D" and the user information is "00000241". At this time, the control unit 221 of the image forming apparatus 200 transmits the authentication data composed of the terminal individual identifier and the user information to the authentication server 300 as the authentication information (B. Authentication printing process). The mobile terminal 400 is a terminal different from the above-mentioned print instruction terminal 500, and corresponds to a "second print instruction terminal" within the scope of the claims.

The print data extraction unit 323 of the authentication server 300 extracts print data that matches the terminal individual identifier of the authentication information from the print data management table 330. In the example shown in FIG. 21, the terminal individual identifier of the authentication information is "AA-BBBBBB-CCCCCC-D", while the terminal individual identifier of the print data management table 330 is "EE-FFFFFF-GGGGGG-D". Therefore, the print data extraction unit 323 cannot extract the print data (S403).

In the authentication printing process in the present embodiment, even when the print data matching the terminal individual identifier cannot be extracted, the process of extracting the print data matching the user information is executed (S405). In the example shown in FIG. 21, the user information of the authentication information is "00000241", and the user information of the print data management table 330 is also "00000241". In this case, the print data extraction unit 323 further determines whether the user information "00000241" of the authentication information matches one of the plurality of user information managed by the image forming apparatus 200 or the print server. The process of collating the user information of the above-mentioned authentication information with the user information of the print data management table 330 and the process of collating with the plurality of user information managed by the image forming apparatus 200 or the print server are performed in S405 of FIG. Is executed by.

When the print data extraction unit 323 determines that the user information "00000241" of the authentication information matches, the print data extraction unit 323 extracts the print data that matches the user information of the authentication information from the print data management table 330. In the example shown in FIG. 21, the print data that matches the user information "00000241" of the authentication information is stored in the print data management table 330.
