Abstract

Echo data hiding is an important approach of audio information hiding in the time domain. But it has serious disadvantages, such as low capacity, relatively low restoration rate and the possibility of malicious tampering, etc. In this paper, based on the simulation analysis of the relation between the detection performance (restoration rate) and the key parameters, we proposed a novel echo M-ary data hiding system using backward and forward echo kernel to improve the weak points of conventional echo data hiding. The subjective quality of the stego audio and the original audio has no evident difference and reach a good hiding effects. The capacity is increased from 50bit/s to 250 bit/s and the restoration rate reaches to 99% for speech in 8000Hz sample frequency, 16 bits quantization, i. e., M=32. And then, we also simulated the robustness performances, such as against adding white noise, resample, filtering, ADPCM compression, etc.
