Abstract

In this paper, we propose a fragile watermarking algorithm for image authentication and integrity. Existing fragile watermarking algorithms had to accept the image distortion in order to insert the watermark. To overcome this drawback, we propose a new fragile watermarking algorithm which can recover the original image after extracting the watermark. Experimental results are presented to demonstrate the validity of the proposed algorithm.
