Watermarking is very useful to secure multimedia and personal data. The protection of watermark image is an issue these days. There are various threats occurs which can change watermark image. This paper is proposing a security mechanism for watermark image using DWT-SVD and optimized chaotic based image encryption through genetic algorithm with high level of robustness and security. The proposed mechanism is implemented on MATLAB, and tested in presence of various attacks. The algorithm is very efficient with respect to other security mechanism. The results are discussed in the paper.
