This paper presents a high-rate information hiding algorithm using digital audio cover.The digital audio has been divided into several sections including the same samples,amplitude of the first two sample points of each section has been compared,according to secret message bit and amplitude comparison,combining the masking effect of HAS(Human Auditory System),and adopting the way of not changing or reducing amplitude of the sample point,the secret message has been embedded into the digital audio.The result demonstrates that the algorithm is robust,invisibility,high-rate hid-data and self-comeback extraction secret message.It is against common signal processing manipulations and attacks,such as resample,append Gaussian noise,low pass filter,and so on.
