【Abstract】 According to the elliptic curve cryptography theory and digital watermarking technique, this paper presents the concepts of secret key and signature watermarking. By using these concepts, the paper proposes a digital watermarking hiding system based on elliptic curve cryptography theory and advances the algorithm of signature-authentication. It is proved that watermarking information signed with classification has strong security and robustness of the system. Besides, the experimental result and its application analysis have also been expounded in the paper.更多还原
