A DWT and DCT based Hybrid Approach for Audio Watermarking?

To obtain the information security and information authentication one of effective approach is watermarking. In this approach, the data is hide behind some multimedia objects. One of such effective watermarking concept is provided by Audio watermarking. In this work, a hybrid approach is presented to perform audio watermarking by using DCT and DWT approaches. In this paper, the presented research model is presented along with proposed algorithm. The implementation results shows that the presented work has provided effective results. The work is analyzed in case of normal case as well as on noise and compression attacks.
