watermarking system on advanced encryption system

A lot of digital watermarking techniques have been proposed to resolve the issues of copyright protection. However, almost proposedwatermarking methods keep the watermarking algorithm private to ensure the embedded watermark secret. If the watermarking technique needs to be widespread applied to realistic multimedia environment, the algorithm used by watermarking techniques should be public. In this paper, a novelwatermarking scheme which can be public is presented.

The proposedwatermarking technique is developed based on the following criterions: (1) the watermarking algorithm is open; (2) the embedded watermark can be extracted and embedded by the people who own the secret key. Thewatermarking scheme employs the advance encryption standard (AES) and the Reed-Solomon code, to make the watermarking algorithm public. Simulation shows that the proposed algorithm can be very robust to resolve the ownership of the digital image.
