Abstract
A reversible and fragile watermarking algorithm based on DCT is proposed for the authentication of digital products. According to the characteristics of high-frequency coefficients of DCT, when the watermarking bit 1 is embedded in an image block, fixed values of some high-frequency coefficients of DCT in the block are modified. However, no modifications will be made when the watermarking bit 0 is embedded in an image block. Mapping for pixel values is used to prevent the overflow of pixel values in this algorithm. The original image is not needed in the extraction of the watermark. The embedded watermark is both reversible and fragile. The experimental results show that the proposed algorithm is practical and effective.
