Research of MP3 Audio Digital Watermark Algorithm Based on Hash Values

Abstract:

This paper puts forwards large audio blind watermark algorithm based on MDCT and compression principles of MP3.Using Hash function, psychoacoustic model and MP3 coding/decoding to realize real-time distilling, and validating watermarking recessive, capability, real-timing and etc through experiment and analysis. Experiments show that the scheme can obtain be a higher embedded capacity to change the original audio signal smaller, has good stealth, integrity watermark extraction time is short, and can be completed synchronously during the audio play process.
