In this paper, we present optical image encryption based on 3-D sphere and phase retrieval in gyrator transform domain. The plaintext is divided into a series of small quadratic blocks, and each block is treated as a particle. The series of particles is distributed in 3-D spheres, and is encrypted into one phase-only mask based on an iterative phase retrieval algorithm. During image decryption, the extracted phase-only mask is rotated and illuminated to sequentially extract a series of focused particles. Subsequently, a decrypted image can be obtained by incorporating all the decoded particles in the transverse domain. Numerical experiment is conducted to demonstrate feasibility and effectiveness of the presented method. © 2013 IEEE. | Source Title: | IEEE Region 10 Annual International Conference, Proceedings/TENCON | URI: | http://scholarbank.nus.edu.sg/handle/10635/84046 | ISBN: | 9781479928262 | ISSN: | 21593442 | DOI: | 10.1109/TENCON.2013.6718955 |
