A SURVEY ON COPYRIGHT PROTECTION OF AUDIO SIGNALS AND STUDY ON THE ROBUSTNESS AND PERFORMANCE ASSESSMENT FACTORS

Abstract

When technology and the internet user’s growth increase exponentially, protecting multimedia data becomes a vital role for the owners. In order to protect the data, the signature is embedded into the host audio signal and can extract the signature to prove the ownership whenever needed. In this article, we survey the recent year’s researched audio watermarking schemes. When the signature is embedded into the host audio signal, the perceptual quality of the host audio should not be disturbed and the schemes should be robust against various attacks such as noise addition, resampling, compression, etc. In this paper, we have examined the different performance assessment factor such as SNR, ODG, and SDG also.
