Aiming at the problem of the interference of camouflage information to the carrier, this paper proposes an information hiding method based on audio technology, and forms a scheme of jointly shaping the camouflage information in the frequency domain and the time domain by the side information. In terms of limiting the interference of the carrier to the camouflaged information, this paper expands the embedding method of the improved spread spectrum modulation when the receiving and sending sequences do not match. The experimental results show that the proposed scheme has a good information hiding effect.
