Abstract

In this paper, a new SVD-based digital watermarking scheme for ownership protection is proposed. The proposed algorithm solves the problem of false-positive detection. In addition, it enjoys all the advantages of SVD-based schemes. Instead of using a randomly generated Gaussian sequence, a meaningful text message is used. Thus, clarity of the extracted message determines the performance of the algorithm. Analytical and experimental developments show that the proposed algorithm is robust and secure. Comparisons with other algorithms indicate that the proposed algorithm is robust against most common attacks. In particular, the algorithm proved to be extremely robust against geometrical distortion attacks.
