Abstract

A robust watermarking scheme for images is proposed. The proposed method can be also be easily extended to other signals like audio and video. In the proposed method an optimal solution is obtained for maximizing the detection statistic (which is an indication of the degree of certainty with which the signature or the watermark is detected), for a given permitted distortion of the host signal, and additive noise variance. Other issues for improving the security of the watermarking scheme, like key based transforms, are also addressed.
