The watermark embedding stage, based on a spread spectrum algorithm operating in the Modulated Complex Lapped Transform (MCLT) domain, inserts a watermark that is generated using a private key which modeled according to the Human Auditory System (HAS). The proposed blind detection approach is based on the Additive White Gaussian Noise (AWGN) channel theory; and to achieve this goal several whitening methods in the receptor side were evaluated. Evaluation results show that the proposed watermarking embedding scheme is robust to common attacks such like, D/A and A/D conversion, filtering, additive noise and high quality MPEG audio coding. 2007 artículo científico 1405-5546 https://www.redalyc.org/articulo.oa?id=61511106 en http://www.redalyc.org/revista.oa?id=615 Computación y Sistemas application/pdf Instituto Politécnico Nacional Computación y Sistemas (México) Num.1 Vol.11 |
