On Line Secret Watermark Generation for Audio Files

Vimal Bibhu

Abstract—This paper presents an on line dynamic robust and efficient approach of audio watermarking for copyright protection. In this paper I am using on line secret watermark generation to generate additional information (watermark) automatically during embedding process. The Direct Sequence Spread Spectrum (DSSS) technique is taken to spread the watermark bits over the entire spectrum of audio signals imperceptibly by creating chip sequences using the bits of watermark. The watermark is shaped in audio signals without the violation of psycho acoustic properties of Human Auditory System (HAS) in frequency domain. The generated watermark is unique for every audio file. The size of watermark depends upon the size and numbers of audio file samples.

Index Terms—DSSS- Direct Sequence Spread Spectrum, HAS – Human Auditory System, HVS – Human Visual System.
