Audio watermarking in wavelet domain using Fibonacci numbers

摘要

In recent times audio watermark has become the centre of attention due to rapid growth of data transmission rates on internet, which has often allowed the unauthorized usage of digital audio files. This paper proposes a Discrete Wavelet Transform (DWT) based blind audio watermarking system. The initial audio undergoes wavelet based approach and later we divide it into frames. Here Fibonacci numbers is used to embed the watermark. SNR values along with error rate are the parameters calculated for execution of this technique. This method provides robust character to various data processing operations like echo, smoothness and reverberation. Greater contents with high imperceptibility is attained by the mechanism as can be interpreted by the simulation outcomes.
