一种鲁棒音频数字水印时域算法
A robust audio digital watermark time-domain algorithm
摘要
Abstract
A robust time-domain audio digital watermark algorithm based on energy difference comparison is proposed. The audio carrier is divided into several sections with equal length according to the watermark sequence being to be embedded,and each section is divided into several segments with equal length. The watermark sequence is embedded into the audio carrier by comparing and modifying the energy difference of the first two segments and the last two segments of each section,and combinating the time-domain masking effect of human auditory system and the watermark sequence being to be embedded. The simulation re-sults show that the algorithm has good transparency and good robustness against various audio attacks,and can realize blind de-tection.关键词
