Abstract

In this paper we propose a spatial domain Spread Spectrum (SS) watermarking scheme which effectively eliminates security problem while increasing robustness and enhancing perceptual quality of watermarked image. VLSI implementation using Field Programmable Gate Array (FPGA) has been developed for the algorithm.
