Embodiment 1

[0074] FIG. 4 is a sequence diagram showing processing performed by the address book management system 1 according to Embodiment 1 of the present invention. The sequence diagram shows an example of transferring a key when transferring address book information. Here, it is assumed that the image forming apparatus 10 and the image forming apparatus 20 use the same encryption system and decryption system.

[0075] In step S1 , the user operates the operation panel 161 of the image forming apparatus 10 to instruct editing of user information contained in the address book 15 . In response to the guidance, the Web service execution unit 12 edits the user information contained in the address book 15 through the UCS 14 .

[0076] Next in step S2, the Web service execution unit 12 determines the encryption range, that is, whether to encrypt all address book information, or only encrypts the password; and uses the key A to perform encryption within a predetermined range.

Embodiment 2

[0087] FIG. 6 is a sequence diagram showing processing executed by the address book management system 1 according to Embodiment 2 of the present invention. This sequence diagram shows an example in which the key C of the distribution server 40 is used as a public key (hereinafter referred to as a public key). Here, the distributed server 40 may be provided by (included in) the image forming apparatus 20 .

[0088] In step S20, the distributed server 40 executes administrator authentication processing and device capability acquisition processing. FIG. 7 is a sequence diagram of an example of administrator authentication processing and device capability acquisition processing.

[0089] Proceeding to step S31 , the distribution module 42 of the distribution server 40 transmits a manager authentication request to the image forming apparatus 10 through the network I / F 41 and the network 60 . Manager authentication information is included in the manager authentication request in s...

Embodiment 3

[0102] FIG. 8 is a sequence diagram showing processing executed by the address book management system 1 according to Embodiment 3 of the present invention. The sequence diagram shows an example in which the key C of the image forming apparatus 10 is used as the common key. Here, the distributed server 40 may be provided by the image forming apparatus 20 .

[0103] In step S40, the distributed server 40 executes the administrator authentication process and the device capability acquisition process as shown in the flowchart of FIG. 7 . Proceeding to step S41 , the distributed module 42 of the distributed server 40 issues a key acquisition request to the image forming apparatus 10 through the network I / F 41 and the network 60 .

[0104] Proceeding to step S42 , the Web service execution unit 12 of the image forming apparatus 10 transmits a response to the key acquisition request issued at step S41 to the distribution server 40 through the network I / F 11 and the network 60 . The...

Abstract

The invention discloses an information management system (1), information processors (10), (20), and an information management method. The information management system includes an information processor and an information management device (30) connected through a network (60). When storing information into the information management device, one of the information processors adjusts the encryption level of the information, the information including two or more items having different security levels, according to a predetermined degree of reliability.

Description

technical field [0001] The present invention relates to an information management system, an information processor, and an information management method; and more particularly, to an information management system, an information processor, and an information management method that manages two or more items having different security levels. Background technique [0002] An information processor such as a personal computer manages user information such as mail addresses as address book information. In addition, image forming apparatuses such as printers, copying apparatuses (copiers), facsimile apparatuses (FAX), and scanners include information processors that manage user information as address book information to manage destinations. Patent Reference 1 discloses an example of such an image forming apparatus. [0003] Recently and in the future, an image forming apparatus is generally connected to a network such as a LAN (Local Area Network), and shares address book informat...
