Abstract: This paper proposes an unusual method for perceptible watermarking algorithm based on the commercial requirements. An audio file is hosted in the website for commercial purpose with a removable watermarking on a portion of it. The objective of this watermark is contrary to that of conventional watermarking. The watermark degrades the quality of the audio file such that it becomes annoyingly perceptible to human auditory system. Chaos theory is used to generate millions of audibly similar but numerically different versions of the watermarked signal. On the removal of this perceptible watermark, a new imperceptible watermark is inserted in the audio as per the conventional requirements. This perceptible method of watermarking is termed as ink marking, and it provides a novel method for digital right management control. The subjective quality tests and robustness tests indicate that the audio quality is excellent. The algorithm is also robust to signal processing attacks.
