摘要：In this paper a fragile watermarking scheme based on adaptive embedding rules is proposed. The watermark embedding and detection rules are applied according to the characteristics of image blocks. In our algorithm we have used gray level variance of image blocks to distinguish it as smooth and unsmooth block. The discrete embedding rules are applied for smooth and unsmooth blocks to improve authentication of the image. In order to access the performance of the proposed scheme copy and paste attack has been applied to the watermarked images. Experimental results have been compared with Hsu and Tu’s [9] method and found significant increase in PSNR of the watermarked images and decrease in False negative rate and False positive rate.
