Abstract
According to the most three important performance indicators of digital watermark, in the paper we put forward a new watermark algorithm which combines wavelet fractal with BSS (blind signal separation) to realize the embedding, detection and extraction of watermark, and it makes use of the character that the chaotic sequence is sensitive to initial value and random alike, by which the embedding point is selected randomly. The experiments prove that the algorithm is effective and robust to resist various attacks
