Unique Key Based Authentication of Song Signal through DCT Transform (UKASDT)

Abstract

Authentication of song signal is one of the assessments to detect the originality in ease of alteration of its content. In this paper, DCT transform has been applied to song signal to extract a unique key for a particular song and which itself represents the characteristics of whole song signal. Comparing song signal with computed and extracted unique keyword unauthorized ownership can be verified. A comparative study has been made with similar existing techniques to compare its characteristics which show better performances. Computed characteristics are also supported through mathematical formula based on Microsoft WAVE (".wav") stereo sound file. © Springer International Publishing Switzerland 2014.
