Abstract
The proliferation of the digitized media (audio, image and video) introduces a challenging problem of security in data transmission In the network environment In this paper a novel algorithm that serves the purpose of covert image-in-image communication and its VLSI implementation using FPGA is proposed. Channel coding and spatial bi-phase modulation scheme are used to map gray-scale image information into a binary equivalent message that extracts message information from the noise less/noisy version of the cover data. Implementation of the proposed low cost algorithm may be speeded up significantly by hardware realization and can be used for real time applications of multimedia data transmission. VLSI implementation using field programmable gate array (FPGA) has been developed for the algorithms and circuit can be integrated into the existing digital still camera framework.
