Advanced optical correlation and digital methods for pattern matching—50th anniversary of Vander Lugt matched filter

TL;DR: The paper reviews some domains that appeared as emerging fields in the last years of the 20th century and have been developed later on in the 21st century, such as three-dimensional object recognition, biometric pattern matching, optical security and hybrid optical–digital processors.

Phase image encryption in the fractional Hartley domain using Arnold transform and singular value decomposition

TL;DR: A novel scheme for image encryption of phase images is proposed, using fractional Hartley transform followed by Arnold transform and singular value decomposition in the frequency domain, and the mask used in the spatial domain is a random amplitude mask.
Journal ArticleDOI

Photon-counting double-random-phase encoding for secure image verification and retrieval

TL;DR: This work shows that photon-limited encrypted distributions have sufficient information for successful decryption, authentication and signal retrieval of complex-valued encrypted data.
Journal ArticleDOI

Improved decryption quality and security of a joint transform correlator-based encryption system

TL;DR: It is shown that it is possible to significantly improve the quality of the decrypted image by introducing a simple nonlinear operation in the encrypted function that contains the joint power spectrum, which makes the system more resistant to chosen-plaintext attacks.

Optical image encryption based on input plane and Fourier plane random encoding.

TL;DR: A new optical encoding method of images for security applications is proposed and it is shown that the encoding converts the input signal to stationary white noise and that the reconstruction method is robust.

Optical encryption by double-random phase encoding in the fractional Fourier domain.

TL;DR: An optical architecture that encodes a primary image to stationary white noise by using two statistically independent random phase codes that has an enhanced security value compared with earlier methods is proposed.

Double random-phase encoding in the Fresnel domain

TL;DR: A lensless optical security system based on double random-phase encoding in the Fresnel domain is proposed, which can encrypt a primary image to random noise by use of two statistically independent random- phase masks in the input and transform planes, respectively.
Journal ArticleDOI

Comparing passwords, tokens, and biometrics for user authentication

TL;DR: This paper examines passwords, security tokens, and biometrics-which they collectively call authenticators-and compares their effectiveness against several attacks and suitability for particular security specifications such as compromise detection and nonrepudiation.
Journal ArticleDOI

Known-plaintext attack on optical encryption based on double random phase keys

TL;DR: A new approach to known-plaintext attack on an optical encryption scheme based on double random phase keys that can be accessed with the help of the phase retrieval technique is demonstrated.
