Digital Audio Watermarking using Frequency Masking Technique
There is a need of an effective watermarking technique for copyright protection and authentication of intellectual Property [12]. In this work we propose a digital watermarking technique which makes use of simultaneous frequency masking to hide the watermark information into host. The algorithm is based on Psychoacoustic Auditory Model and Spread Spectrum theory [2]. It generates a watermark si...
متن کاملRobust audio watermarking using perceptual masking
We present a watermarking procedure to embed copyright protection into digital audio by directly mod ifying the audio samples Our audio dependent watermarking procedure directly exploits temporal and frequency perceptual masking to guarantee that the embedded watermark is inaudible and robust The wa termark is constructed by breaking each audio clip into smaller segments and adding a perceptual...
متن کاملA Source Reassignment Technique for Time-frequency Masking Audio Separation
A neighborhood-based source reassignment technique is proposed for being used on time-frequency masking audio source separation methods. This technique identifies all the time-frequency clusters that form the separation masks in the Short-Time Fourier Transform (STFT) domain, and labels each time-frequency bin with a value that denotes the size of their corresponding clusters. The bins correspo...
متن کاملDigital Audio Watermarking: Survey
Digital audio watermarking is a technique for embedding additional data along with audio signal. Embedded data is used for copyright owner identification. A number of audio watermarking techniques are proposed. These techniques exploit different ways in order to embed a robust watermark and to maintain the original audio signal fidelity. This paper makes a tutorial in general digital watermarki...
متن کاملDigital Blind Audio Watermarking
Digital audio watermarking techniques are widely applied to protect the ownership of digital audio media. This study presents an audio watermarking scheme for audio e-leaning contents. The proposed audio watermarking method can significantly reduce the bit error rates, so enhance the robustness against common attacks. The experimental results under common attacks demonstrate that our watermarki...
