STUDY OF THE EFFECTED GENETIC WATERMARKING ROBUSTNESS UNDER DCT AND DWT DOMAINS

Watermarking becomes the suitable technology to protect multimedia in digital world. Watermarking using genetic algorithm for the optimization of the tread- off between the watermarking requirements has attracted the attention of researchers; amongst the watermarking requirements, the robustness is an important one. Watermarking embedded in frequency domain using DWT or DCT can affect the robustness of watermarking, this paper studies the effect of embedding domain on the robustness in genetic watermarking. Results of attacks based on numerical correlation (NC) is analyzed through the paper sections, the DWT results showed more robustness than DCT in watermarking based on GA
