摘要：In today’s world, a large number of data is available on the Internet. It is almost impossible to deal withnumerous challenges like copyright protection, content identification, verification and authentication of digital data.Watermarking is a technique that is used all over the world to solve the issue of copyright protection. Digitalwatermarking is used due to its wide range of applications from copyright protection, protection of digital data, digitalfingerprinting to author authentication to many more. This paper mainly deals with a different video watermarkingtechnique based on frequency domain and their comparison is evaluated on the basis of Peak-Signal-To-Noise (PSNR)Ratio. This comparison is done in the MATLAB/Simulink which is an interactive tool for simulation purposes.
