In recent time protection of intellectual properties is a concern. To protect the image and video from the unauthenticated access or tampering, watermarking is adopted as a solution. Real-time implementation of various watermarking techniques has been utilized in broadcasting. In this paper we have 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.
