Abstract :
A new digital image zero-watermarking algorithm based on CDMA technology has been proposed in this paper. Zero-watermarking is a new technique of watermarking and CDMA is a mature technology in communication. The new algorithm combines the characters of two techniques to create the image zero-watermark. The simulate experiments show that the new algorithm has good performance under multiple attacks.
