Abstract VoIP (Voice over Internet Protocol) is based on voice stream, which has the advantages of large data transmission and wide application. But the VoIP system is confronted with the security threats of data security and privacy disclosure. Thus, according to nonergodicity and redundancy of the fixed codebook search, an information hiding algorithm based on fixed codebook search process is proposed. This information hiding algorithm is carried out by a functional relationship between the nonzero pulse positions and secret information. The idea of least significant pulse replacement is used in the search process and a distortion minimization criterion is proposed to control the distortion of speech quality caused by the embedding of secret information. The experimental results show that the hiding capacity of the proposed algorithm is up to 400 bit/s and the average PESQ score is 3.45 which indicate that the algorithm has good imperceptibility.
