In the example of FIG. 8, when there are three types of authentication methods of PIN code authentication, password authentication, and biometric authentication as authentication methods of the mobile terminal 2, guest authority, user authority, and administrator authority are assigned to each authentication method. It is assumed that three types of user authority are set so as to correspond to each other.

In the example of FIG. 8(A), if the user of the mobile terminal 2 has administrator authority as the upper limit of authority, the authentication methods of PIN code authentication, password authentication, and biometric authentication are guest authority. , corresponding to general user rights and administrator rights respectively.

In the example of FIG. 8(B), if the user of the mobile terminal 2 is a general employee whose upper limit of authority is user authority, the authentication methods of PIN code authentication and password authentication correspond to guest authority and general user authority, respectively. .

On the other hand, in the initial settings, biometric authentication corresponds to administrator authority, but if the user of mobile terminal 2 is a general employee, the upper limit of that authority is general user authority, so the corresponding user authority is , it becomes a general user privilege, not an administrator privilege.

In this way, even if the user authority based on the authentication status of the mobile terminal 2 exceeds the upper limit of the registered user authority, user authority within the upper limit of authority registered for each user can be obtained. is set.
Therefore, even if user authentication information is not registered in the main body of the login processing device 4 or the authentication server in advance, the digital composite provided with the login processing device 4 performs appropriate user authentication according to the security level than before. Machine 1 can be realized.

[Embodiment 3]
Next, an example of user authentication processing of the user authentication system 100 according to Embodiment 3 of the present invention will be described with reference to FIGS. 9 to 11. FIG.

FIG. 9 is an example of a flow chart showing user authentication processing of the user authentication system 100 according to Embodiment 2 of the present invention.

The processes of steps S31 to S33 and S35 to S40 in FIG. 9 correspond to the processes of steps S11 to S13 and S15 to S20 in FIG. 7 (embodiment 2), respectively, so description thereof will be omitted.
Here, the processes of steps S34, S41 and S42 in FIG. 9, which are not shown in FIG. 7, will be described.

In step S33, when the authentication function is disabled (when the determination in step S33 is No), the control unit 10 notifies the user of the mobile terminal 2 of a login error and prevents the user of the mobile terminal 2 from using the MFP. (step S33).

FIG. 10 is an explanatory diagram showing an example of a login error notification to the user of the mobile terminal 2 according to Embodiment 3 of the present invention.

In the example of FIG. 10, the display unit 251 of the mobile terminal 2 displays a message "Login error! Login to MFP 1 failed because authentication of this terminal cannot be confirmed."

Also, as "If you want to log in again, please select an authentication method." A proposal for a login method by authentication is displayed on the display unit 251 as well.

Therefore, the user can choose any re-login method to re-login.

In addition, as shown in the example of FIG. 10, the display unit 251 also displays a message "If an error occurs three times, you will not be able to log in for a certain period of time." Login from the mobile terminal 2 may not be accepted for a predetermined period of time.

Next, in step S40 of FIG. 9, after executing the login processing based on the user authority set in the login processing unit 19 (step S40), in step S41, the control unit 10 authenticates the user of the portable terminal 2. The result and user authority are notified, and a proposal for a login method based on other authentication of the portable terminal 2 is also notified (step S41).

FIG. 11 is an explanatory diagram showing an example of notification of the authentication result and user authority to the user of the mobile terminal 2 according to the third embodiment of the present invention.

In the example of FIG. 11, the display unit 251 of the mobile terminal 2 displays a message "You have logged into the MFP 1 based on the PIN code authentication of this terminal. User authority: Guest user."

Also, as "If you want to re-login with a different method, please select an authentication method." A proposal for a login method is displayed on the display unit 251 as well.

In this case, the user authority corresponding to each authentication method may also be displayed on the display unit 251. FIG.

(Modification)
As a modification of the third embodiment, the display unit 251 may display only authentication methods that allow login with user authority higher than the current time.

By doing so, the user can select a re-login method with higher user authority and re-login.

Next, after the process of step S34 or S41 in FIG. 9, in step S42, the control unit 10 determines whether or not the user of the portable terminal 2 has requested to log in again using the authentication method selected (step S42).

When there is a re-login request from the mobile terminal 2 (when the determination in step S42 is Yes), the control unit 10 returns the process to step S31.

On the other hand, when there is no re-login request from the mobile terminal 2 (when the determination in step S42 is No), the control unit 10 terminates the user authentication process.

In this way, the user of the mobile terminal 2 is proposed a re-login method by authenticating the mobile terminal 2 after login or after a login error.
Therefore, even if user authentication information is not registered in the main body of the login processing device 4 or the authentication server in advance, the digital composite provided with the login processing device 4 performs appropriate user authentication according to the security level than before. Machine 1 can be realized.
