Abstract: Digital watermarking is a developing technology which ensures and facilitates security, authentication and copyright protection of digital data. Digital watermarking is the method of hiding digital data in any form of multimedia data such as image, audio, video, etc. This paper performs a comparative analysis of different hybrid image watermarking techniques. The watermarking techniques based on a combination of DCT and DWT is implemented. These methods use Singular Value Decomposition (SVD) of the cover image and watermark for embedding the watermark. Different attacks are applied on the watermarked image in order to analyze the robustness of each algorithm.
