US 2012/0072971 A1 · DATA SHARING SYSTEM, SHARED DATA MANAGEMENT APARATUS, AND CONTROL METHOD OF SHARED DATA MANAGEMENT APPARATUS

Abstract

The traffic amount of the radio communication is reduced and the load applied to the management side of the system is reduced, thereby making the data shared with only prescribed users in an efficient manner. There is provided a shared data management apparatus, for managing sharing of data stored in a plurality of data storage units, is provided with: a profile group management unit 201 for managing attribution information of users; a group processing unit 202 for creating a user group based upon the attribute information; a sharing policy management unit 203 for managing an authority information permitting a user included in the user group to share the data stored in the data storage unit, so that the profile group management unit 201 identifies the user group permitted to share the data stored based upon the authority information. The shared data management apparatus is further provided with a data sharing process unit 204 for storing the stored data in a data storage unit owned by the user included in the identified user group.
