Abstract :
The research and application of semi-fragile digital watermark is being paid more and more attention now, especially for content authentification. We proposes a novel design for image content authentification based on semi-fragile digital watermark using side information, which combines the modern RSA public key encryption technique with communication principle just like spread spectrum technology. The advantage of our scheme is more robust, secure, and simply implemented to some extent.
