Generation and fabrication of authenticated song signal through preserving balance ratio of song´s components (BRSAS)

In this paper, an algorithm has been proposed to provide security to digital songs through generating a correlation between amplitude and phase components of song signal without changing its audible quality. Generating interrelationship between amplitude and phase signals with the help of wavelet transform (symmetrization mode) is the first phase of proposed technique followed by fabrication of authenticating ratio of amplitude and phase components throughout the song using a constant ratio. The interrelationship as well as authenticating code will use to detect and identify the original song from similar available songs. A comparative study has been made with similar existing techniques and experimental results are also supported with mathematical formula based on Microsoft WAVE (".wav") stereo sound file.
