Description

  The present invention relates to an image forming system and a user manager server device.

  In recent years, directory services such as an active directory and an e directory have been introduced to manage users and devices in a network system. Some image forming apparatuses such as printers, copiers, and multifunction machines have a network function, and currently users and groups (departments) can be managed using such a directory service. When performing user management with a directory service, user authentication of a user who has performed a login operation on an image forming apparatus is usually performed by a server apparatus of the directory service.

  On the other hand, in the image forming apparatus, an authorization process may be performed in which only a function permitted to the login user among various functions can be used. Normally, in the authorization process, for each user, authorization information that designates a function that is permitted to be used (or a function that is prohibited to be used) is preset in the image forming apparatus, and is used by the login user in accordance with the authorization information. Function to be limited. In addition, there is also a system that provides the login user authorization information to the image forming apparatus using an intermediate server device having authorization information for each user (see, for example, Patent Document 1).

  Further, in a system in which a plurality of image processing apparatuses and server apparatuses are connected to a network, there is a technique for performing user authentication and collective management of charging information for each user in the server apparatus (see, for example, Patent Document 2).

  In the authorization policy data 51 shown in FIG. 4, the domain group A includes domain users A, B, C, and D, and the local group A includes local users A and B and domain users B and D. An authorization policy # 1 (policy data including authorization information) is set for the domain group A, an authorization policy # 2 is set for the domain user A belonging to the domain group A, and an authorization policy # for the local group A 3 is set, the authorization policy # 4 is set for the local user A belonging to the local group A, the authorization policy # 5 is set for the domain user B belonging to the domain group A, and the authorization for the domain user E is set. Policy # 6 is set, and authorization policy # 7 is set for local user C.

  The local user data 52 is data including registration information (user ID and password) of the local user. The local user is a user registered in the user manager device 3 separately from the domain user registered in the directory server device 4.

  The local group data 53 is data including registration information (group ID and user ID of a user belonging to the group) of the local group. The local group is a group registered in the user manager device 3 separately from the domain user registered in the directory server device 4. Local groups can include local users and domain users. That is, a local group consisting only of local users, a local group consisting only of domain users, and a local group consisting of local users and domain users can be set.

  The network interface 42 can be connected to a wired or wireless computer network 2 and performs data communication with other devices (such as the multifunction devices 1A and 1B and the server device 4) connected to the network 2. Device.

  The arithmetic processing unit 43 is configured as a computer having a CPU, a ROM, a RAM, and the like, and loads various programs stored in the ROM or the storage device 41 into the RAM and executes them by the CPU, thereby realizing various processing units. . In the arithmetic processing device 43, a network communication unit 61, a user authentication processing unit 62, an authorization processing unit 63, and a job tracking processing unit 64 are realized.

  The network communication unit 61 is a processing unit that controls the network interface 42 and performs data communication with devices on the network 2 using various communication protocols. For example, the network communication unit 61 receives a user name (user ID) and a password from the multifunction device 1A, and transmits authorization information about the user to the multifunction device 1A. For example, the network communication unit 61 transmits a user authentication request to the directory server device 4 and receives the authentication result and user information from the directory server device 4.

  The user authentication processing unit 62 is a processing unit that uses the network interface 42 to authenticate the login users of the multifunction peripherals 1A and 1B with the directory server device 4.

  When the login user of the multifunction device 1A (or multifunction device 1B) who has succeeded in user authentication belongs to the local group, the authorization processing unit 63 extracts the authorization information for the local group from the authorization policy data 51 and logs in the login information. When the login user who has transmitted user authorization information to the MFP 1A (or MFP 1B) using the network interface 42 and succeeded in user authentication does not belong to the local group, the domain group to which the login user belongs or the Processing for extracting authorization information for a user (domain user or local user) from the authorization policy data 51 and transmitting it to the MFP 1A (or MFP 1B) using the network interface 42 as authorization information for the login user. In the department That.

  For example, in the case of the authorization policy data 51 shown in FIG. 4, when the domain user A logs in to the multifunction device 1A, the authorization policy # 2 and the authorization policy # 1 are transmitted to the multifunction device 1A. When there are conflicting authorization settings in the user and group authorization policies (here, authorization policy # 2 and authorization policy # 1), the setting of a predetermined authorization policy of the group or user is applied. In this case, when the domain user B logs in to the multifunction device 1A, the authorization policy # 5, the authorization policy # 3, and the authorization policy # 1 are transmitted to the multifunction device 1A. If there are conflicting authorization settings in the domain group and local group authorization policies (here, authorization policy # 1 and authorization policy # 3), the setting of the predetermined authorization policy of the domain group or local user is applied. Is done. In this case, when the domain user C logs in to the multifunction device 1A, the authorization policy # 1 is transmitted to the multifunction device 1A. In this case, when the domain user D logs in to the multifunction device 1A, the authorization policy # 1 and the authorization policy # 3 are transmitted to the multifunction device 1A. In this case, when the domain user E logs in to the multifunction device 1A, the authorization policy # 6 is transmitted to the multifunction device 1A. In this case, when the local user A logs in to the multifunction device 1A, the authorization policy # 4 and the authorization policy # 3 are transmitted to the multifunction device 1A. In this case, when the local user B logs in to the multifunction device 1A, the authorization policy # 3 is transmitted to the multifunction device 1A. In this case, when the local user C logs in to the multifunction device 1A, the authorization policy # 7 is transmitted to the multifunction device 1A.

  When there are a plurality of authorization policies to be applied to a certain login user, the authorization processing unit 63 generates a single authorization policy by combining the authorization policies in the server device 3 and transmits the generated authorization policy. You may make it do. In that case, any setting policy selected according to a predetermined rule is applied to setting items that compete with each other in a plurality of approval policies.

  The job tracking processing unit 64 is a processing unit that receives job log information from the multifunction peripherals 1A and 1B using the network interface 42, and collects the job log information as a user job history for each domain user and local user. When no local user is set, the job log information is collected as a user job history for each domain user. The job log information is information generated when a job of a logged-in user who has succeeded in user authentication is executed in the multifunction peripherals 1A and 1B, and includes a user ID of the logged-in user, a job type (print, scan, copy, Facsimile transmission, etc.), and other accompanying information (such as a counter value of the number of pages of various attributes (color, monochrome, duplex printing, etc.)). For example, when there are users as shown in FIG. 4, job log information having the user ID of each user for each of the domain users A to E and the local users A to C is collected as a user job history. Therefore, by sending the user job history to a predetermined address by e-mail, file transfer protocol, etc. or making it viewable, it is possible to easily confirm what job the user has executed in the past.

  Thus, the user manager server device 3 is configured.

  FIG. 5 is a block diagram showing the configuration of the directory server device 4 in FIG. The directory server device 4 includes a storage device 71, a network interface 72, and an arithmetic processing device 73.

  The storage device 71 is a device that stores programs and data. As the storage device 71, a nonvolatile semiconductor memory, a hard disk drive, or the like is used. A directory service database 91 is constructed in the storage device 71, and the database 91 includes user data 91a and group data 91b. The user data 91a includes a user ID, a password, and user information (a telephone number, a facsimile number, an e-mail address, and other attribute information to be contacted). The group data 91b includes a group ID, a user ID list of users belonging to the group, and group information (contact information, responsible person, and other attribute information).

  The network interface 72 is a device that can be connected to a wired or wireless computer network 2 and performs data communication with other devices (such as the server device 3) connected to the network 2.

  The arithmetic processing unit 73 is configured as a computer having a CPU, a ROM, a RAM, and the like, and implements various processing units by loading a program stored in the ROM or the storage device 71 into the RAM and executing the program by the CPU. In this arithmetic processing unit 73, a network communication unit 81 and a directory service processing unit 82 are realized.

  The network communication unit 81 is a processing unit that controls the network interface 72 and performs data communication with devices on the network 2 using various communication protocols. For example, the network communication unit 81 receives a user authentication request and transmits the authentication result and user information.

  The directory service processing unit 82 is a processing unit that manages domain users and domain groups. The directory service processing unit 82 performs registration and deletion of domain users and domain groups, user authentication, provision of user information of domain users and group information of domain groups, and the like. For user authentication, LDAP (Lightweight Directory Access Protocol) authentication, Kerberos authentication, or the like is used. When the directory service is an active directory, the directory service processing unit 82 operates as a domain controller.

  Thus, the directory server device 4 is configured.

  Next, the operation of each device when the user logs in to the multifunction device 1A in the above system will be described. FIG. 6 is a sequence diagram for explaining the operation of each device when a user logs in to the multifunction peripheral 1A in the system shown in FIG. Each device operates in the same manner when a user logs in to the multifunction machine 1B.

Use to transmit to the user manager server device 3 (step S2).

  In the user manager server device 3, the user authentication processing unit 62 receives the user name and password using the network communication unit 61 and the network interface 42, and sends the user name, password, and authentication request to a predetermined protocol (LDAP LDAP). Etc.) to the directory server device 4 (step S3).

  In the directory server device 4, the directory service processing unit 82 uses the network communication unit 81 and the network interface 72 to receive the user name, password, and authentication request using a predetermined protocol, and refers to the directory database 91. It is determined whether or not the user name and password are those of a valid user (step S4).

  Then, the directory service processing unit 82 uses the network communication unit 81 and the network interface 72 to display the determination result (that is, the authentication result) and the user information of the user when the authentication is successful. As a response, it transmits to the user manager server apparatus 3 (step S5).

  In the user manager server device 3, the user authentication processing unit 62 uses the network communication unit 61 and the network interface 42 to receive the authentication result as a response to the authentication request. Receive information. When the authentication is successful, the authorization processing unit 63 refers to the authorization policy data 51, specifies the authorization information of the user (that is, the authorization policy applied to the user) (step S6), and the network Using the communication unit 61 and the network interface 42, a response indicating successful authentication is transmitted to the multi function device 1A together with the authorization information and user information (step S7).

  In the MFP 1A, the control unit 33 receives the authorization information and user information using the network communication unit 32 and the network interface 23, and provides the authorization information to the determination unit 34 (step S8). Based on the authorization information, the determination unit 34 sets, on the RAM, data indicating whether or not the use of the user is permitted for each of the predetermined functions of the multifunction peripheral 1A.

  Thereafter, the user is permitted to use the multifunction device 1A in a state where the function is restricted according to the authorization information (step S9). In the MFP 1A, the control unit 33 refers to the above-described data set by the determination unit 34 and accepts and executes only jobs that use functions permitted for the user.

  When user authentication fails, only a response indicating authentication failure is transmitted from the user manager server apparatus 3 to the multifunction device 1A. When the multifunction device 1A receives a response indicating authentication failure, the message indicating authentication failure is transmitted. Is displayed on the operation panel 21 and the use of the multifunction device 1A by the user is prohibited.

Thereafter, in the MFP 1A, the control unit 33 generates job log information each time a job of a logged-in user who has succeeded in user authentication is generated, and uses the network communication unit 32 and the network interface 23 to generate a user manager server device. 3 (step 10).

  The job tracking processing unit 64 receives job log information using the network communication unit 61 and the network interface 42 and stores the job log information in the RAM or the storage device 41. The job tracking processing unit 64 collects job log information for each domain user and local user in response to a request from a host device (not shown), the multifunction peripheral 1A, 1B, or the like (step S11). For example, when a logged-in user performs a predetermined operation on the multifunction device 1A, the control unit 33 of the multifunction device 1A transmits a job log information aggregation request to the server device 3 together with the user ID of the user. Upon receipt of the request, the job tracking processing unit 64 of the server device 3 extracts and combines job log information about the user with the user ID received together with the request, and collects the job log information as a user job history. As a response to the request, it is transmitted to the multifunction device 1A, and when the control unit 33 of the multifunction device 1A receives the job log information, it displays it on the operation panel 21 or the like. Further, the job tracking processing unit 64 may classify each user and collect the job log information when receiving the job log information.

  As described above, according to the first embodiment, each of the plurality of multifunction peripherals 1A and 1B generates job log information when a job of a login user who has succeeded in user authentication is generated, and associates the job with the login user. The blog information is transmitted to the user manager server device 3, and the user manager server device 3 performs user authentication of the login user with the directory server device 4, receives job log information from the plurality of multifunction devices 1A and 1B, Blog information is collected as a user job history for each domain user (and local user).
