Due to the characteristics of medical image:huge data and high continuity of same color pixels,a medical imageencryption algorithm based on chaos theory was proposed.The algorithm generates encryption array by randomly switching among multiple one-dimensional chaos systems,introduces duplex feedback to the image data while encryp-ting,which lengthens the sequence period and improves the security of algorithm.Experiment results show that the algorithm has good running efficiency and encryption effect.
