A new secure video watermarking for copyright protection

In application of copyright protection, two problems must be considered. One is that an adversary edits a watermark to be embedded, and claims he is owner of the work. The other is he finds a legal watermark and embeds it to his work (copy attack). To solve the two problems, a secure and robust video watermarking method for copyright protection is proposed. The proposed algorithm is used in the proof of ownership of video chunks and resisting the copy attack. Some analyses and experimental results show that the proposed video watermarking has a good security and robustness for copyright protection.
