Abstract: Safeguarding creative content and intellectual property in a digital form has become increasingly difficult as technologies, such as the internet, broadband availability and mobile access advance. It has grown to be progressively easier to copy, modify and redistribute digital media, resulting in great declines in business profits. Digital watermarking is a technique which has been proposed as a possible solution to this problem. Digital Watermarking is a technology which is used to identify the creator, owner, distributor of a given video or image by embedding copyright marks into the digital content, hence digital watermarking is a powerful tool used to check the copy right violation. A robust watermarking technique based on DWT (Discrete Wavelet Transform), DCT (Discrete Cosine Transform) and combined DWT-DCT is presented. In these techniques the insertion and extraction of the watermark in the gray scale image is found to be simpler than other transform techniques. All three methods are simulated using two watermarking algorithms. The performance of the two algorithms is evaluated by applying various attacks on the watermarked image and results tabulated. This paper describes SDRAM control which enhances the overall performance.
