英文摘要	A new kind of hash algorithm of speech perception was proposed with the help of human auditory model in order to improve the robustness of speech perception hash algorithm and the ability to identify tampering with a small scale positioning. Firstly, the method controlled the number of filters of the MFCC (Mel frequency cepstral coefficients) algorithm based on human auditory characteristics, and obtained the Mel frequency cepstral parameters of each frame of speech. Secondly, it fused the AMFCC (adaptive Mel frequency cepstral coefficients) parameter and the LPCC (linear prediction cepstrum coefficients), and dealed with characteristic matrix using blocking. At the same time, it processed 2DNMF (two-dimensional nonnegative matrix factorization) decomposition algorithm to characteristic blocks, so the complexity of the characteristic matrix was reduced. Finally, coefficient matrixes after decomposition were hashed to get the hash string of speech perception. The voice authentication could be realized by hash matching. The results show that the algorithm is able to enhance the robustness of hash authentication and achieve tamper localization of small range. ©, 2015, Huazhong University of Science and Technology.
