针对MP3压缩域比例因子的音频水印算法
Watermarking algorithm based on scalefactors in MP3 compression domain
摘要
Abstract
Scalefactor related information in MP3 bitstream and its function in decoding process are analysed. This paper proposes a digital audio watermarking algorithm for MP3 compression domain. Since the algorithm chooses proper scalefactors, it can effectively control the influence of embedded watermark on original audio media, and the watermark is inaudible, while utilizing chosen conditions the algorithm achieves self-adaptation and implicit synchronization. Simulation experiments show that the proposed algorithm not only has good hearing transparency and robustness, but also embeds and extracts fast enough to meet real-time needs.关键词
