Embedding data in edge boundaries with high PSNR

Data hiding is one of the most significant aspects in information security. Generally data embedding is achieved in communication, image, text, voice, or multimedia content for copyright, military communication, authentication and many other purposes. Currently available data hiding techniques do not pay much attention on stego-object (hidden information in original object) with respect to its originality with cover (original) object. Both cover and stego-objects are drifted in context of (quality measure in image, like) Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) aspects. This paper proposes a data hiding method around the edge boundary of an object with high PSNR. The stego-image can be utilized for further processing aspects (segmentation etc). The experimental results show very high rate of PSNR. Proposed scheme is targeted for low rate of hidden data capacity with high PSNR.
