Lossless Fragile Watermark Based on Directional Wavelet and Histogram Shift
摘要
Abstract
This paper designs a new lossless fragile watermark based on directional wavelet and histogram shift. It can be used at integrity verification and Iossless restoration. The watermark is generated by directional wavelet transformation and embedded by histogram shift and the embedding position can be decided by user's key. By comparing the extracted watermark and the one computed from the reconstructed image, it can be decided if the image has been tampered or not. The watermark can be totally excluded and the original picture can be obtained if the picture passes the integrity verification.关键词
