Reversible data hiding which can recover the original image without any distortion after extraction of the hidden data has drawn considerable attention in recent years. However, the problems of underflow and overflow have occurred occasionally in watermarked image. To overcome these problems, we propose a new reversible data hiding algorithm based on histogram modification of block image. In addition,...
In this paper, we propose a new reversible data hiding algorithm using the histogram modification of difference images. The histogram modification method has been used for reversible data hiding remarkably. However, this method has the underflow/overflow problems. To overcome these problems, we embed the compressed location map to identify the points of underflow and overflow. Therefore, the proposed...
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...
