Development of an audio watermarking with decentralization of the watermarks

In this paper, a digital watermarking technique for ensuring security to an audio signal is presented. The proposed technique is developed by using discrete wavelet transform (DWT) and singular value decomposition (SVD). The proposed technique is executed by incorporating multi-level DWT along with the use of multiple images with different sizes as watermarks. The proposed technique is developed by keeping in mind the distribution of watermark...
