Abstract

The present study derives a novel scheme to embed the watermark for high authentication, robustness, security and copyright protection based on Fuzzy Wavelet. So far no researcher has attempted to use fuzzy logic in the spatial domain. The present paper developed a new technique called Fuzzy Wavelet (FW) approach for selecting the pixel locations to insert the watermark. The main aim of the proposed method is embedding the watermark image fully and to extract the watermarked image in an efficient manner. The approach is called Fuzzy Wavelet Region based Even, Odd (FWREO) method. The watermark bits are embedded in the pixel location selected by the FW approach by using the novel approach called Region based Even Odd (REO) method. The proposed method mainly consists of two steps. In step one, identify the pixel locations where the watermark is embedded. In the second step, REO method is applied on the FW approach of the first step. To find the effectiveness of the proposed method, the present method is tested on 24 images with the size of 512×512. The proposed gives comparative results when compared with other existing methods.
