Method of Digital-audio Watermarking Based on Cochlear Delay Characteristics
This paper proposes a state-of-the-art method of digital-audio watermarking, based on the properties of the human cochlear. It is based on the concept of embedding inaudible watermarks (e.g., copyright data) into an original sound by controlling the phase characteristics of the sound in relation to the characteristics of cochlear delay. The method involves two processes, i.e., embedding and det...
متن کاملSpread-spectrum watermarking of audio signals
Watermarking has become a technology of choice for a broad range of multimedia copyright protection applications. Watermarks have also been used to embed formatindependent metadata in audio/video signals, in a way that is robust to common editing. In this paper, we present several novel mechanisms for effective encoding and detection of directsequence spread-spectrum watermarks in audio signals...
متن کاملDWT-based audio watermarking
Many effective watermarking algorithms have been proposed and implemented for digital images and digital video, however, few algorithms have been proposed for audio watermarking. This is due to the fact that, the human audio system is far more complex and sensitive than the human visual system. In this paper, we describe an imperceptible and robust audio watermarking algorithm based on the disc...
متن کاملAn Audio Blind Watermarking Scheme Based on DWT-SVD
In order to protect the digital audio and video products copyright in the network, an improved audio blind watermarking algorithm scheme based on discrete wavelet transform (DWT) and singular value decomposition (SVD) is proposed. In the algorithm, an original audio is split as blocks and each block is decomposed on discrete wavelet transform for two degree, then first quarter audio approximate...
متن کاملAudio Watermarking Based on Compression-expansion Technique
A novel robust audio watermarking scheme is proposed in this paper. In the proposed scheme, the host audio signals are segmented into frames. Two consecutive frames are assessed if they are suitable to represent a watermark bit. If so, frequency transform is performed on these two frames. The compressionexpansion technique is adopted to generate distortion over the two frames. The distortion is...
