Abstract

One way for copyright protection is digital watermarking. Digital watermarking is the process of embedding information regarding the authenticity or the identity of the owners into a image or any piece of data. Digital watermarking has been classified into two types :Visible and Invisible Watermarking. In visible digital watermarking, the embedded information is visible. Typically, the information is text or a logo, which identifies the owner of the image. In invisible digital watermarking, information is added as digital data to audio, picture, or video, but it is not visible. Watermarking degrades the quality of an image. By the use of Reversible watermarking the embedded watermark can be removed and restore the original content. The lossless image recovery is a difficult task but; it is important in most of the applications where the quality of the image is concerned. There are many methods for visible watermarking with lossless image recovery. One to One compound mapping is one of the technique. The compound mapping is reversible and it allows lossless recovery of original images from the watermarked images. Security protection measures can be used to prevent illegal attackers.
