JIP_V3_N4_RP3 V. Belmer Gladson Y. Sam Josuva R. Balasubramanian Journal on Image Processing 2349-6827 3 4 19 25 Reversible Watermarking, Least Significant Bit (LSB), Difference Expansion (DE), Reversible Contrast Mapping (RCM), Wavelet-Fuzzy (WF) The Reversible watermarking is a field of hiding the information, which hides the crucial information in different forms like an image, song, video for protection of illegal duplication and distribution of multimedia data. This research work is to embed data in encrypted images and decrypt the image to rebuild the original image by removing the hidden data without any distortion. There are many researches in this field and various techniques were proposed. So in order to choose which one is the best technique, a definite need arises to compare with the techniques like Least Significant Bit (LSB), Difference Expansion (DE), Reversible Contrast Mapping (RCM), Wavelet-Fuzzy (WF) and these reversible watermarking methods are analyzed with the help of metrics PSNR, MSE, Processing Time and Correlation. From the experimental results and performance evaluation, LSB is better, but based on correlation and after applying a median filter, Wavelet- Fuzzy (WF) provides better results.
