Paper Abstract

The robustness and security of random phase encoding technique are analyzed. We study the tolerance to data loss of the decrypting key for binary text and a grayscale image. To enhance the security, an improved phase coding scheme based on the chaos theory is proposed. The proposed optical setups for image decryption are depicted. The analyses show that the improved scheme can effectively improved the security.
