Abstract

According to the renewable and the noise-like characteristic of chaotic signal, the effective frequency band and the energy band of image information are used to carry out the chaotic masking transmission, so as to achieve the security transmission of image information. Chen chaos is selected as the carrier to carry out the chaotic masking transmission for the image information of the two time-frequency aliasing under the positive definite transmission model, and the blind extraction algorithm is used to restore it in the receiver. The influence of additive noise source on the extraction effect is analyzed, and a secure transmission method of image information under chaotic masking is proposed in this paper.
