Hardware Software Co-simulation of Watermarking algorithm for Image Processing Applications

In recent days, the unauthorized replication problem causes many copyright ownership disputes regarding the originality of the digital contents. Digital watermarking is the best solution for this problem. The main challenges in designing a digital watermarking are robustness, speed and tradeoffs involved. A watermark inclusion and extraction system is designed without affecting the quality of the image considering the security. To overcome the unaccepted delays a speedy embedding technique is required. A novel water marking algorithm for images using Discrete Wavelet Transform (DWT) is proposed which minimizes the complexity, robustness, resource utilization and security for data processing. The proposed watermark embedding and extraction algorithm is implemented using Xilinx System Generator.
