In order to overcome the shortcomings of standard compressive sensing (CS) encryption framework, a novel fusion application scheme CS and optical transformation technology is proposed. The proposed scheme, making full use feature achieve compression simultaneously, compresses encrypts two images into one image, which not only reduces storage space transmission bandwidth, but also improves secur...

Biometric authentication is a rapidly growing trend that gaining increasing attention in the last decades. It achieves safe access to systems using biometrics instead of traditional passwords. The utilization biometric its original format makes it usable only once. Therefore, cancelable template should be used, so can replaced when attacked. Cancelable aims enhance security and privacy authenti...

In this paper, we discuss optical encryption and decryption considering wireless communication channels. In wireless communication systems, the wireless channel causes noise and fading effects of the transmitted information. Optical encryption technique such as double-random-phase encryption (DRPE) is used for encrypting transmitted data. When the encrypted data is transmitted, the information ...
