摘要
文章依据MP3音频文件的压缩原理及特点,提出了一种能够用于MP3音乐文件版权保护的数字水印算法.该算法通过与MP3编码与解码过程相结合,能够实现水印信息的实时提取,具有良好的感知透明性、较好的实时性和相对较低的计算复杂度.
Proposes a copyright protection for large-capacity MP3 audio watermarking algorithm based on MP3 audio file principles and compression characteristics.The algorithm with MP3 encoding and decoding process achieves the extraction of the watermark information in real time,and has a good perception of transparency,excellent imperceptibility and lower computational complexity.
