Decomposition of an Image Cryptography Scheme That One Based On or Its Transformed Version to Be Watermarked

Abstract

Cryptography and watermarking are two key aspects for information hiding to communicate secure information from one source to other source over network. The communication over network is very secure due to these techniques. These two techniques are differing from each other for hiding information behind or in image. In this paper we present that if these two techniques are combined together than what good results can come out with effect. In the proposed method “Cryptography” is used to encrypt the plain text message in to the cipher text using the Hill Cipher Algorithm, and second technique is “Watermarking “for the image decomposition or its transformed version using self-fractional Fourier function (SFFFs). So this method is much effective than older ones.
