Abstract:
Color image encryption algorithm based on ptychography technology is researched in this paper. In order to encrypt the color image,we use sinusoidal combinational grating to encode color image into gray image,and then the gray image is encrypted by ptychography and double random phase encoding. The encryption system not only enlarges the key spaces and enhances system security,but also the resistance of shear and noise performance are strong. The encryption system is simpler and more practical. The simulation proves the validity of the encryption system.
