Abstract—This paper proposes an efficient watermark generation method for audio copyright protection and digital right management. It proposes a method of generating pseudorandom sequences based on iris image templates. These biometric generated sequences (bio-keys) are found to be unique for distinct identification purposes. These bio-keys are used as the watermark for audio signals. The correlation of the extracted bio-key with a database of 150 bio-keys reveals that the best correlation is 1 while the next best correlation is less than 0.4 under no attack condition. Even under serious signal processing attacks, the bio-keys have distinctly been identified and mapped in a database. Experimental results of listening evaluation and robustness tests have confirmed that the use of bio-keys maintains good perceptual property and offers strong resistance to the typical signal processing attacks.
