|Issue Date:||1-Sep-2012||Citation:||Chen, W., Chen, X. (2012-09-01). Interference-based optical image encryption using three-dimensional phase retrieval. Applied Optics 51 (25) : 6076-6083. ScholarBank@NUS Repository. https://doi.org/10.1364/AO.51.006076||Abstract:||In recent years, optical image encryption has attracted more and more attention in information security due to its unique advantages, such as parallel processing and multiple-parameter characteristics. In this paper, we propose a new method using three-dimensional (3D) processing strategy for interference-based optical image encryption. The plaintext is considered as a series of particles distributed in 3D space, and any one sectional extraction cannot render information about the plaintext during image decryption. In addition, the silhouette problem in the conventional interference-based optical encryption method is effectively suppressed, and the proposed optical cryptosystem can achieve higher security compared with the previous work. A numerical experiment is conducted to demonstrate the feasibility and effectiveness of the proposed method. © 2012 Optical Society of America.||Source Title:||Applied Optics||URI:||http://scholarbank.nus.edu.sg/handle/10635/56378||ISSN:||00036935||DOI:||10.1364/AO.51.006076|
