基于数字水印和加密技术的Internet音乐保护

Internet Music Protection Based on Digital Watermarking and Encryption

提出了一种基于数字水印和加密技术的Internet音乐保护方法,并针对两种适用于Internet在线传输的音乐格式:压缩音乐和MIDI,提出了两种快速和鲁棒性强的数字水印加入方法,以保护Internet在线音乐的知识产权。对于压缩音乐,采用部分解压来加入水印且加入方法与音乐内容紧密相关;对于MIDI,水印被加在一些虚拟音符中,这些虚拟音符随机地隐藏在MIDI音符中。

In order to protect the intellectual property of Internet music, this paper proposes a music protection method based on digital watermarking and encryption technologies, and presents two fast and robust digital watermarking schemes for compressed music format and MIDI format, which are suitable for on-line distribution through Internet. For compressed music, the watermark is embedded in partialy uncompressed domain and the embedding scheme is highly related to music content. For MIDI. the watermark is embedded in virtual notes that are generated and randomly hidden among the MIDI notes.
