一种基于离散小波变换的抗重录音鲁棒音频水印算法
A Discrete Wavelet Transform-based Anti-replay Audio Watermarking Algorithm
摘要
Abstract
In order to solve the problem of illegal transmission and use of audio content after rerecording,a robust audio watermarking algorithm was proposed.Based on discrete wavelet transform,Discrete Wavelet Transform-Coefficient Logarithmic Mean(DWT-CLM)was defined,the relationship between DWT-CLM and the approximate components of DWT was analyzed,and a watermark embedding method was proposed based on DWT-CLM.Experimental results showed that the proposed algorithm had the good inaudibility and anti-signal processing ability,especially in the signal processing to meet a certain robustness,and a certain tolerance for re-recording attacks.关键词
