Audio Watermarking by using Image Comparison

Audio Watermarking is commonly used to establish the authenticity of original audio signals. In this Paper a new robust Audio Watermarking algorithm is proposed which is based on Image Comparison. To make such algorithm more robust we used a 2-D image matrix which gives good results in terms of performance, robustness, imperceptibility and speed. This Watermarking technique shows good performance against the various attacks such as Additive White Gaussian Noise (AWGN), cropping, echoing, low pass filtering, requantization, and Resampling. The proposed technique has been shown to be efficient and has stable performance against various attacks with additional advantage of being computationally faster.
