Recently, a collusion resilient video fingerprint method has been proposed utilizing desynchronization. But a question has not been considered for this method: secure transmission for multicast / broadcast. Because every copies using this method have different desynchronization, all the traditional fingerprint broadcasting techniques do not work. In this paper, we propose a method for securely broadcasting desynchronized video copies. The video is firstly lengthened and partially encrypted in the sender side and broadcasted to every user, and then on the receiver side, the video is desynchronized and embedded by fingerprint, and then decrypted. We give a method to implement this for MPEG-2 stream. Experiments indicate the effectiveness of the fingerprinted copies for collusion robustness and the efficiency of transportation. Security of the system is also analyzed with probable attacks and corresponding solution is proposed.
