A Novel Audio Watermarking Algorithm for Copyright Protection of Digital Audio

A Novel Audio Watermarking Algorithm for Copyright Protection of Digital Audio

Jongwon Seok et al. 181 Digital watermark technology is now drawing attention as a new method of protecting digital content from unauthorized copying. This paper presents a novel audio watermarking algorithm to protect against unauthorized copying of digital audio. The proposed watermarking scheme includes a psychoacoustic model of MPEG audio coding to ensure that the watermarking does not affe...

Audio Digital Watermarking for Copyright Protection

When dealing with copyright protection for audio, watermarking can be considered to label the digital medium, by hiding information into the data. To make the watermark imperceptible and robust against some signal processing, we propose in this paper a new method based on frequential substitution, for which the bit error rate is lower than those obtained with existing methods. For such a purpos...

A Novel Audio Aggregation Watermarking Algorithm Based on Copyright Protection

A novel algorithm of audio aggregation watermarking was proposed in this paper for copyright protection. The algorithm not only protects copyright of a single audio in audio aggregation but also protects copyright of the whole audio aggregation. The experimental results showed the watermark of aggregate audio can resist to some attacks, for example, deleting audio, and substituting audio; at th...

Robust 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 ...
