Abstract :
A kind of image asymmetric digital watermarking algorithm based on eigenvector of symmetric matrix is proposed in this paper. The algorithm used correlation detection and the watermarking can be detected in a blinding way. The experimental results indicate the algorithm is robust to rotation, scaling, noise and some other attacks, especially to the combination of some attacks.
