摘要: The present invention aims to overcome drawbacks of conventional content tracing methods requiring re-processing the before its broadcast with a significant side channel transmission i.e. extra processing, storage and/or bandwidth at distribution side, or alternately complex signal processing implementation receiver that has be protected against hackers attacks. An efficient system and method consists uniquely identifying decoders video stream wherein implement least one variant standard image decompression algorithm resulting decompressed approximation varies according decoders' identifier.
