Reversiblee Image Authentication Based on Watermarking
2006
2006 IEEE International Conference on Multimedia and Expo
In this paper, we propose a new reversible image authentication technique based on watermarking where if the image is authentic, the distortion due to embedding can be completely removed from the watermarked image after the hidden data has been extracted. This technique utilizes histogram characteristics of the difference image and modifies pixel values slightly to embed more data than other lossless data hiding algorithm. We show that the lower bound of the PSNR (peaksignal-to-noise-ratio)
