Optical image encryption and security using random phase encoding techniques have been proposed recently. We present optical experimental results for image encryption and security. The results show that for the image encryption, the image can be well encrypted using random phase masks with a limited number of pixels. We also tested the performance of the optical system for security verification in the presence of different types of input noise and distortions such as scratches, fingerprint marks, and bending of the phase mask. The experimental results indicate that for the severity of the noise and the degree of distortion tested here, the system provides good performance in verifying the phase code.
