A Novel Watermark Algorithm Based on the Shamir Theory

摘要

Based on the research on wavelet-chaos watermark algorithm, a novel algorithm is proposed with the application of shamir sharing theory. In the new algorithm, some digital watermark information is embedded to the image by shamir sharing theory. The proposed method is feasible and efficient. The experimental result shows that the new algorithm has very good visual effect, more security and robustness than the traditional wavelet-chaos algorithm.
