Image Encryption Technique Based on Partial Differential Equation

摘要：

A new image encryption technique is proposed here by solving reversible partial differential equation (PDE). If an original image was selected as corresponding initial condition of the PDE, the original image would be distorted as time goes on. Hence, the original image is encrypted to prevent unauthorized access. To resume the original image, the flow field in the reversible PDE should be reversed until the same time goes on. Numerical experiments were successfully solved to verify the desired efficiency of method.
