Abstract :
Error correction encoding combining with spread spectrum scrambling are adopted in fingerprint generation. We construct Trace ability Codes (TA codes) by Reed-Solomon codes which have significant burst-error-correcting capability, and then scramble the TA codes by spread spectrum code. The generated digital fingerprint is capable of resisting normal video attacks and realizing effective tracing of traitor users in illegally distributed versions. Embedding algorithm is mainly applied in MPEG-2 compressed video, it embeds fingerprint into each I-frame of the video by means of data repetition technique so as to ensure accurate extraction of fingerprint.
