一种心理声学模型的自同步音频水印方案
摘要
Abstract
This paper introduces a robust digital audio watermarking scheme. The features of the scheme are as below:(1)using dual-scrambling mechanisms to ensure the security of the watermark;(2)using psychoacoustic models to determine the watermark embedding strength;(3)using synchronization mechanisms to achieve watermark self-synchronize detection;(4)using DWT domain watermarking to improve anti-attack capability;(5)using efficient embedding algorithm to improve the efficiency of wa-termark detection. Simulating experimental results show that the scheme not only has excellent imperceptible feature, but also can stably withstand various attaches such as re-sampling, re-quantifying, noise adding, low pass filtering and MP3 compressing.关键词
