%X Because there are large amounts of and varieties of images in digital museum,a blind watermark algorithm suitable for multiple types image is proposed.In order to track the use of image,user's ID is used as watermark.While embedding watermark,first the watermark is translated into corresponding ASCII code,and in order to resist against burst and random(error),the watermark is then interleaved and BCH coded.We then classify the image and get the carrier for embedding watermark.At last,we do DCT on center of the carrier and modify coefficients in DCT domain to embed watermark.On extracting,watermark is extracted in a contrary embedding procedure and we compute the similarity of the extracted watermark and each user ID to find the originally embedded ID.Preliminary experiment shows that our algorithm can resist against ordinary signal processing and special geometric translation.
