Abstract
In this paper, we present a new robust digital watermarking method by applying a conventional fragile watermarking method. Since the candidate pixels for embedding are selected from among the smooth image area having a good tamper recovery rate, a good detection rate of watermarked information is provided. Our method also produces a high PSNR of the recovered image by improving the accuracy of the prediction value for the recovery against the tampered pixel. We demonstrate the experimental results concerning the quality of the watermarked image and the watermark detection rate in the case of embedding 8000 bits.
