Secure Communication of Images with Bandwidth Conservation Scheme

Abstract

We proposed a novel approach for highly secure, stable and simplified communication system. — In this paper we use 2 level DWT and DCT watermarking to bring a complex and secure system. Other main aim of the paper is to implement watermarking of several images under single cover. The paper also review the advantages of using proposed system in particular watermarking of several (4) images under single cover reduces the bandwidth required to transmit the data. This paper describes the proposed algorithm, implementation and results. Four images and single cover is used to test the system and the results are much efficient than existing systems.
