Paper Abstract

The technological efficiency and growing research in digital networks, devices, and transmission has made digital multi-media an increasingly popular alternative to conventional analog media. With the recent advancements in internet and multi-media technologies, the need for secured multimedia has increased exponentially. In this paper, we present a logical subband based novel secured multimedia system for digital images that could be used for both data hiding and cryptographic applications. It decomposes the cover into various integer valued sub-images that also provides the location map of flippable subband coefficients. Moreover, this approach enhances the capacity of data hiding system by a significant amount of data and simultaneously reduces the visible distortions that could occur in the image. In addition, this technique could also be employed for cryptographic applications, as this framework offers lossless recovery of the scrambled data and effective scrambling. Simulation results show that the proposed technique limits the changes to boundary regions of the image. Further, this approach can retrieve the embedded information without prior knowledge of the original unmarked image.
