Audio watermarking , Wavelet Packet Tree, Singular Value Decomposition, Advanced Encryption Standard


In this paper, an adaptive audio watermarking scheme using a Randomly generated Wavelet Packet Tree (RWPT) and Singular Value Decomposition is proposed. The audio signal is first decomposed using RWPT and then the watermark image is embedded into certain sub bands by taking care of the psychoacoustic properties of the human ear. RWPT structure is further encrypted using AES (Advanced Encryption Standard) algorithm.
