英文摘要	In this paper, we present a novel time-frequency domain robust speech perceptual. hashing algorithm based on Ililbert transform for speech content authentication, and effectively solve a poor robustness problem of the speech content perceptual, authentication under the low-pass filter and white Gaussian noise, identify tamper detection and localization of small scale. Firstly, this algorithm for speech signal, pre-processing, evaluated short-time energy of each frame signal, as time domain perceptual, feature value. Secondly, each frame signal, for Ililbert, transform and two dimensional, discrete cosine transform (2D-DOT) constitute a frequency domain feature matrix and evaluate its Shannon entropy as the frequency domain perceptual, feature value. Finally, quantify the time domain and. frequency perceptual feature value to get the authentication perceptual, hashing sequences. The experiment results illustrate that when compared with the existing schemes, the proposed scheme has a good, robustness and. discrimination for content-preserving manipulations, the robustness is largely improved under the low-pass filter and white Gaussian noise operations, and lower computational, complexity, and can realize precision tamper detection and localization. © 2015 ICIC International.
