Fragile Watermarking Scheme for Image Tamper Detection

摘要

In this paper, a fragile watermarking scheme is proposed for Tamper Detection in images. Here, watermark is derived from the original host image, which is consists of reference-bits and check-bits and is embedded into the host image using a lossless data-hiding technique. On the receiver side, one can attempt to extract the watermark bits and recover the original image. By comparing the watermark data extracted from received image and calculated from recovered image, tamper blocks can be identified.
