At present, the problem that exists in the gray image encryption is easy to be cracked. Aiming at it, this paper proposes a kind of encryption method based on BP neural network. This method uses the very strong nonlinear transform ability of neural network to improve the security of image information. This paper detailed describes the specific implementation process of encryption method based on BP neural network. Through the simulation experiment, good results have been achieved
