Ownership Identification and Signaling of Multimedia Content Components

Multimedia content protection is conventionally applied at file level, which cannot cope with the case when the ownership of each media content component is different from each other. And different operations could be expected by different owners when their content components are subjected to unauthorized access. To address these issues, a new method for ownership identification and signaling of content components is proposed for smart media streaming. Prior to streaming, ownership of each media content component is first identified using watermarking or media fingerprinting, then signaled in media presentation description with possible operation list previously decided by its owner. At presentation, each content component will be handled according to the signaling information. Experiments on large datasets demonstrate the efficacy and efficiency of the proposed method.
