“…In 1995, Refregier et al, proposed a famous image encryption technology based on Dual Random Phase Encoding (DRPE) [ 3 ]. Subsequently, various improved DRPE-based optical encryption schemes were proposed [ 4 , 5 , 6 , 7 , 8 ]. However, there are still many important issues that need to be resolved, such as speckle noise, real-time encryption, data storage density, and transmission security [ 9 ].…”

An optical encryption method based on computer generated holograms printing of photopolymer is presented. Fraunhofer diffraction is performed based on the Gerchberg-Saxton algorithm, and a hologram of the Advanced Encryption Standard encrypted Quick Response code is generated to record the ciphertext. The holograms of the key and the three-dimensional image are generated by the angular spectrum diffraction algorithm. The experimental results show that large-size encrypted Quick Response (QR) code and miniature keys can be printed in photopolymers, which has good application prospects in optical encryption. This method has the advantages of high-density storage, high speed, large fault tolerance, and anti-peeping.

This paper investigates and presents a block-based opto-color cipher using double random phase encoding (DRPE) with different block sizes. The color plainimage is divided into equal-sized blocks and then converted to an optical signal by an optical emitter. The obtained optical signal is encrypted by employing the DRPE technique, which applies two types of phase modulation, time, and Fourier domains. Finally, the optical color cipherimage is, upon detection, converted to digital format by a charge-coupled device digital camera. Experiments and security analysis show that the proposed block-based optical color image cipher using DRPE with increased block size is secure, effective, and including a good immunity to channel noise. INDEX TERMS DRPE, Fourier domain, optical color image, time domain, and image encryption.
