摘要：The interest in data hiding has raised with the recent activity in digital copyright protection schemes. One way to protect the ownership of a digital image is to secretly embed data in the content of the image identifying the owner. In particular we will describe how one can use watermarking to hide information in a digital image. Multiple watermarking is used for embedding multiple watermarks into the host single to provide authentication without bearing on the optical quality of the image. Some digital watermarking techniques ensure the host-signal noise while associating the watermark in chronological sequence on experienced image data. Our aim is to embed an watermark which contains information into an edge image and find out that if there will be any attack on images such as .jpeg then the information embedded in an image will not be change that is the attack will survive on such images
