This paper proposes a new fragile watermarking algorithm which is mainly applied to binary document image based on the wet paper code. In order to improve embedding capacity and locating tampered area, some work is done base on the prior research of fragile in this paper. First, we dynamically adjust the bits which are embedded into image according to the number of turnover pixels and make the turnover...
Some work is done to improve embedding capacity and locate tampered regions base on the prior research of fragile document watermark in this paper. And an effective fragile document watermarking algorithm is proposed. The wet paper code which adjusts the number of embedding watermark bits dynamically and takes full advantage of turnover pixels is used for embed watermark to improve embedding capacity...
