Region Based Even Odd Watermarking Method With Fuzzy Wavelet

Authors: S.Maruthuperumal, G.Rosline Nesakumari, V.Vijayakumar

To overcome the weak robustness problem of embedding the watermark in the spatial domain and to provide high authentication, the present paper presents a novel watermarking scheme with two steps. In the step one, the proposed method modifies the original image in transform domain and identifies the pixel location to insert the watermark bits in the difference values between the original image and its reference image based on a novel fuzzy logic method. To provide high authentication and security in the step two, the watermark bits are embedded in the pixel location selected by step one using Region based Even Odd (REO) Method. The Fuzzy Wavelet (FW) scheme of step one eliminates the requirement of original image for the watermark extraction. The experimental result indicates the efficacy of the proposed method when compared with the various other methods.
