摘要
Abstract
This paper combines the characteristics of Moving Picture Experts Group Audio Layer 3(MP3) encoding, and presents a digital watermarking algorithm for MP3 audio files.It goes on watermark embedding and extraction directly in the compressed domain.The watermark is embedded in MP3 by slightly modifying the scale factors in bit stream, the method does not need encode the sound data into an MP3 file or decode the MP3 file.Experimental results show that the size of the audio file is not changed in the embedding process, and it does not need original audio file when watermark is extracted.The algorithm has advantages of higher real-time, lower computational complexity and excellent imperceptibility.关键词
