Patent ID: 8826369

Claim:
A communication system which comprises: a terminal of a user; and a server which processes a predetermined service on a basis of sensor data, wherein the terminal comprises: a sensor interface unit to acquire the sensor data including user's environment information and user's biological information; a management policy storing unit to store a policy table including a management policy which defines utilization form of the sensor data including concealment rules of a terminal identifier of a data source according to a combination of sensor data and a service using the sensor data; a sensing management unit to acquire the management policy corresponding to the combination of the sensor data and the service with reference to the policy table; and an application execution unit to process the sensor data only within the terminal when the utilization form of the sensor data defined by the management policy specifies to process the sensor data only within the terminal, and to send, at least, ID (IDentifier) information which identifies the terminal, the sensor data, and the management policy to the server when the utilization form of the sensor data defined by the management policy specifies to process the sensor data in the server, and wherein the server comprises: a policy management unit that carries out a concealing process which conceals the ID information corresponding to a data source of the sensor data on a basis of the concealment rules in the management policy; and a service processing unit that processes the predetermined service on a basis of the sensor data and the ID information to which the concealing process has been applied.
