An Accurate Image Juggling Authentication Algorithm

摘要：

A fragile watermarking algorithm used in accurate tamper authentication of image content is proposed. The algorithm can distinguish tampered pixel points accurately and tolerate transmission error of individual authentication information bits which take place in image transmission. This algorithm produces authentication information by expanding more pixels within four-left, right, up and down directions around the pixel, then the problem that single tampered pixel point cant be located accurately which cause by some algorithms based on image uncertainty by combining surrounding pixels to locate embedded watermarking bits. Authentication information is embedded after encryption to resolve security vulnerability problem appears in most pixellevel authentic algorithm.
