Recently, a novel nonlinear encryption system based on joint transform correlator (JTC) in the Gyrator domain (GD) was proposed. The encryption system uses a fully nonlinear nonzero order JTC and Gyrator transform (GT). The decryption system is based

In this work, we present the integration of the photon counting technique (PhCT) with an encryption system in the Gyrator domain (GD) for secure image authentication. The encryption system uses two random phase masks (RPMs), one RPM is defined at the
