In this paper, the color image authentication and recovery method using the moment-preserving method is proposed. The color image is partitioned into non-overlapping blocks for watermark embedding. The watermark for each block consists of its authentication data and the corresponding feature information that is composed of a bit map and two representative pixel values. The bit map and the two representative pixel values are computed by the moment-preserving technique. In the proofing process, the authors check authentication data to obtain the results of tamper proofing.
