Abstract:
1. A tamper proof processing arrangement for connection to a communications system, comprising: a receiving agent arranged to receive user-related data and a usage rights object from the communications system; a data processor arranged to process the user-related data under the control of the usage rights object so as to derive elements usable in further processes from the user-related data and generate an output signal, the output signal identifying the elements and an identification of the further processes for which these elements may be used; and an output interface for output of the output signal; wherein the data processor is arranged not to retain the user-related data after the output signal has been generated; wherein the user-related data is encrypted using a content encryption key by a rights issuer agent of the communications system, and wherein the usage rights object is generated from usage rules using the same content encryption key.
