Optical Encryption and Authentication Based on Phase Retrieval and Sparsity Constraints

Optical Encryption and Authentication Based on Phase Retrieval and Sparsity Constraints

Complex holographic schemes are usually required to obtain complex-valued encrypted images that are used for verification in previously proposed authentication approaches based on photon-counting imaging and double-random-phase encoding (DRPE). In this paper, we propose an optical information encryp...
