Abstract

A novel full-phase digital holographic encryption scheme with double random key masks, which are performed by electrically addressed liquid-crystal spatial light modulators for optical processing, is demonstrated. Phase-shifting digital holography is employed to generate the key holograms derived from the double key masks for implementing the encryption and decryption. The experimental results show the feasibility of the full-phase encryption scheme with computer-programmable key masks for securing data via online processing.
