Digital Audio Watermarking Techniques for MP3 Audio Files
نویسندگان
چکیده
Nowadays, a vast amount of information concerning all aspects of human activity is digitised with the goal of profit. One of the most prominent examples is the music industry that now markets audio data mainly in the form of MPEG Audio Layer 3 files rather than on CDs or DVDs. The MP3 audio files are distributed as digital files through various communication means and can easily be copied and retransmitted. In such an open environment, the issue of security and copyright AbstRAct

Random Sample Audio Watermarking Algorithm for Compressed Wave Files
In this research work, various audio watermarking techniques have been studied and investigated. A novel audio watermarking method is proposed in which watermark is added transparently after ADPCM (Adaptive Differential Pulse Code Modulation). In the proposed scheme we have used random sample instead of fixed or low frequency carriers to embed the watermark into the audio bit stream. Proposed t...
متن کاملRobust Audio Watermarking for Copyright Protection
This paper introduces an audio watermark encoding system that is robust to commonly used audio compression techniques such as MP3, AAC and OGG. The watermark is embedded by applying MPEG Layer 2 Model 2 psychoacoustic masking in an iterative way. The decoding is performed by using a correlation based blind decoding algorithm supported via a wavelet denoising module. Unlike most of the existing ...
متن کاملAn Authentication Method for Digital Audio Using a Discrete Wavelet Transform
Recently, several digital watermarking techniques have been proposed for hiding data in the frequency domain of audio files in order to protect their copyrights. In general, there is a tradeoff between the quality of watermarked audio and the tolerance of watermarks to signal processing methods, such as compression. In previous research, we simultaneously improved the performance of both by dev...
متن کاملA Watermarking Scheme for MP3 Audio Files
In this work, we present for the first time in our perception an efficient digital watermarking scheme for mpeg audio layer 3 files that operates directly in the compressed data domain, while manipulating the time and subband/channel domain. In addition, it does not need the original signal to detect the watermark. Our scheme was implemented taking special care for the efficient usage of the tw...
