Combined the image encryption and hiding technique, this paper proposed a method of color image protective transmission based on Logistic map and LSB hiding algorithm. Firstly, Logistic map produced three chaotic sequences by one secret-key. Secondly, the image pixel matrixs of R,G,B were permuted by the chaotic sequences and digital image encryption was realized in the space domain. Finally, the encrypted image was embedded in the carrier image by LSB hiding algorithm to transmission. This paper also made qualitative and quantitative analysis of the effects of the project from aspects of operation speed, key sensitivity, anti-attack capability. Experimental results show that the method has advantages of good secrecy, high security and fast operation speed.
