基于KMP的高效半脆弱音频水印算法
Efficient Semi-fragile Audio Watermark Algorithm Based on KMP
摘要
Abstract
An efficient semi-fragile audio watermark based on KMP is proposed in this paper, which can tolerate general signal processing, detect any spiteful tamper on marked multimedia data, and locate spatial regions within an altered image. Synchronous signals are employed to position the embedded watermark so as to improve the accuracy of watermark extraction. KMP calculation is adopted in searching the synchronous signals to increase efficiency. The algorithm can locate tampered regions without the help from the original watermark. Experimental results show that the proposed algorithm has the advantages such as simple computation complexity, good robustness against shearing attack, and accurate location for tamper.关键词
