China (Received April 25 2019, accepted June 11 2019) In \u00a0this \u00a0paper, \u00a0we \u00a0investigate \u00a0the \u00a0color \u00a0image \u00a0encryption \u00a0based \u00a0on \u00a0fractional-order \u00a0memristive neuron \u00a0system \u00a0and \u00a0DNA \u00a0coding \u00a0technology. \u00a0The \u00a0proposed \u00a0encryption \u00a0method \u00a0consists \u00a0of \u00a0two \u00a0stages: permutation \u00a0and \u00a0diffusion. \u00a0Some \u00a0numerical \u00a0examples \u00a0are \u00a0exploited \u00a0to \u00a0demonstrate \u00a0the \u00a0feasibility \u00a0of \u00a0the encryption algorithm, and the security analysis shows that the algorithm has high security and good resistance to statistical attacks.
