Abstract :
This paper deals with a new digital audio watermarking scheme based on Code Division Multiple Access (CDMA) technique. In digital communication, CDMA allows several users to share the same communication channel without interference from each other. The present work proposes to embed multiple watermarks in the same audio channel in order to increase the embedded information. Our main objective is to emphasize the impact of spreading codes on the performance of CDMA based watermarking system. This performance will be evaluated in terms of transparency, detection reliability of the watermark and its robustness against various disturbances.
