摘要
To solve the problem of efficiently and securely transmitting perceptual hash values in speech perceptual hashing authentication systems, a transparent and robust audio reversible watermarking algorithm is proposed in this paper. This algorithm, which is based on phase coding improved by bipolar quantization, guarantees its security by Logistic mapping. Experimental results show that the proposed algorithm has good reversibility, transparency, robustness and security, and has better comprehensive properties.
