A Robust True-Color Watermarking Scheme Based on Discrete Cosine Transform

Abstract:

A watermarking technique for true-color image based on double random phase encryption method and digital holography is proposed. Three different watermark images are encrypted into three holograms, respectively. Then, three holograms are hiding into a true-color image. Watermark extract method has also been described detailedly. Simulation Results indicate that our proposed watermarking technique can resist physical attack well and has a high security degree of hidden information.
