Embodiment approach 1

[0085] FIG. 1 is a diagram showing an overall configuration of a group information management system according to the first embodiment.

[0086] The group information management system 1 is used to license digital works such as music (hereinafter also referred to as "contents") or express rights to use digital works among terminal devices within a predetermined number (for example, 5) that can be registered in a group. A system for copying, moving, or reproducing content at the moving destination, as shown in FIG.

[0087] The group management server 20 is a computer device that holds group information 281 and a list 251 of group terminals belonging to each group, wherein the group information 281 is unique information for each group for judging whether it belongs to a group, and the list 251 of terminal belonging to each group indicates List of terminal devices belonging to each group. When the group management server 20 receives the deletion end notification message M3 for ...

Embodiment approach 2

[0128] Figure 9 It is a diagram showing the overall configuration of the group information management system 2 according to Embodiment 2 of the present invention. Parts corresponding to constituent parts of the group information management system 1 are assigned the same reference numerals, and detailed description thereof is omitted.

[0129] In order to distribute the load on the group management server 20 in Embodiment 1, the group information management system 2 divides the group management server 20 into a plurality of devices, such as Figure 9 As shown, the network 10, the public group management server 30 connected to the network 10, a plurality of individual group management servers 40a-40j connected to the network 10, and the terminal list management of the public group management server 30 and the individual group management server 40 are managed in a unified manner. The device 50 and terminal devices 70a to 70n connected to the network 10 are configured.

Abstract

A group management server (20) in a group information management system (1) includes: a group member terminal list storage unit (25) for storing a group member terminal list (251); and a secure communication unit (21) for establishing a secure communication channel with a plurality of terminal apparatuses (60) and communicating with each of the terminal apparatuses (60) via the communication channel. Each terminal apparatus (60) includes a tamper-resistant module (68), and the tamper-resistant module (68) includes: a group information storage unit (65) for storing group information securely; a deletion unit (67) for securely executing deletion, which is processing that affects the group member terminal list (251), on the group information stored in the group information storage unit (65); and a secure communication unit (64) for establishing a secure communication channel with the secure communication unit (21) and transmitting a complete deletion notification message (M3) via the communication channel.

Description

technical field [0001] The present invention relates to an information management system that connects a plurality of terminal devices that store data and an information management server that manages management information related to the data via a network, and particularly relates to performing processing on data that affects management information in each terminal device , the executed technique is confirmed by the information management server. Background technique [0002] In recent years, digital works (hereinafter also referred to as "contents") such as music, images, and games have become easy to obtain through the distribution of packaged media in addition to the Internet or digital broadcasting. Furthermore, regarding the use of these digital works, from the viewpoint of copyright protection, etc., studies have been conducted on rights management and use control methods for digital works that limit the number of reproductions of digital works, movement, copying, et...
