Optimized Audio Watermarking Based On Discrete Transformation for Secure Transmission
Publication Date : 16/03/2016
Many effective watermarking algorithms have been suggest and implemented for digital images and digital video. However, a few algorithms have been suggest for audio watermarking. This is due to the fact that, human auditory system (HAS) is far more complicated and sensitive than human vision system (HVS). In this research work, a new method of embedding image information into the audio signal and pertaining audio watermarking algorithm based on Discrete Cosine Transformation (DCT) and Discrete Wavelet Transformation(DWT) domain is proposed. The process of embedding a watermark image on an audio signal in such a way that there are no audible changes in the audio and it seems exactly like the original audio.
