Simulation & Analysis Image Authentication Using Xsg with Matlab: Simulation & Analysis of Image Processing Applications & Frequency Domain Image Authentication Using Xsg with Matlab Arvind Yadav

The Xilinx system generator, which provides a novel model based approach of carrying out various image processing applications. The model is prepared using Xilinx blockset that has a potential to be implemented on FPGA Devices. Multimedia authentication techniques are required in order to ensure trustworthiness of multimedia data. They are usually designed, based on two kinds of tools, Digital signature or Watermarking. Frequency domain based approach of watermarking is introduced in authentication system in order to get more feasibility in terms of better concealing and robustness of integrated information. This authentication system may be based on different transforms like DCT, DWT and LSB etc. and that can be implemented in the MATLAB SIMULINK tool, integration of Xilinx will allow the access of Xilinx block set, and by incorporating this block sets in model based design can help us to generate VHDL code for modelling by Xilinx System Generator. This code can be optimized manually to get fast execution time and high performance. Once the code is generated then it can be synthesized in Xilinx ISE and implemented on Hardware.
