摘要:
A method for achieving a secure recording and storing of a recorded activity is based on an extended Digital Rights Management (DRM) system. A recording and storing procedure is initiated, in response to recognizing one or more triggers at a device hosted by a user equipment. On the basis of the one or more triggers a Rights Issuer is located, and a Recording and Storing Instruction (RSI) is retrieved from the RI, using an existing DRM standard. Based on the RSI, a trusted storage for storing the recorded activity is located, and one or more recording procedures, involving one or more recording equipments, are activated and managed by the device. Before the recorded content is forwarded to the trusted storage, a protected content is generated from the recorded content, according to content of the RSI.
