英文摘要	Aiming at the existing problems of audio authentication algorithms, such as problems that audio files are kept in a single format and algorithms are not generic and low efficiency, an audio perceptual hashing authentication algorithm for multi-format audio based on energy to zero ratio was proposed. Firstly, the audio signal was processed by applying preprocessing, framing, and adding window to calculate the short-time energy and the number of short-time zero-crossing of each audio frame and to obtain the ratio value of them. Secondly, the ratio value of short-time energy and the number of short-time zero-crossing was used as the perceptual feature value of audio signal. Finally, the feature values were used to conduct a hashing structure process to produce the perceptual hashing sequence. In order to improve the security of the algorithm, the perceptual hashing sequence was scrambled by a key which has the same length as the sequence. Experimental results show that the proposed algorithm has a high efficiency in terms of perceptual robustness, discrimination and time consumption for audio signal with five different formats in uncompressed domain and compressed domain. © 2017, Editorial Board of Journal of Huazhong University of Science and Technology.
