This paper presents a comparative study between the watermark encryption algorithms that are applied for audio signals. The chaotic Baker map and DES with its four modes are used as watermark encryption algorithms. Encrypted watermark is embedded in audio signal using both SVD and block based SVD methods. Experimental results show that the OFB mode is the least sensitive to attacks compared with the chaotic Baker map.

Abstract


This paper presents a comparative study between the watermark encryption algorithms that are applied for audio signals. The chaotic Baker map and DES with its four modes are used as watermark encryption algorithms. Encrypted watermark is embedded in audio signal using both SVD and block based SVD methods. Experimental results show that the OFB mode is the least sensitive to attacks compared with the chaotic Baker map.
