MPEG 비디오를 위한 하이브리드 워터마킹 알고리즘
Hybrid Watermarking Algorithm for MPEG Video
초록
In this paper, we propose a hybrid watermarking algorithm for MPEG bitstream. Hybrid watermarking technique uses Spread Spectrum technique for I-frame and Motion Vector technique for P, B-frame. Thus, it enables all MPEG frame to be watermarked. By applying above technique, it is possible not only to protect intellectual property right but also to be robust to all kinds of attacks. And this scheme requires partial decoding of MPEG bitstream, so it can be applied to real time watermarking applications.
