Speckle-based optical cryptosystem and its application for human face recognition via deep learning. (arXiv:2201.11844v1 [cs.CR])

Face recognition has recently become ubiquitous in many scenes for
authentication or security purposes. Meanwhile, there are increasing concerns
about the privacy of face images, which are sensitive biometric data that
should be carefully protected. Software-based cryptosystems are widely adopted
nowadays to encrypt face images, but the security level is limited by
insufficient digital secret key length or computing power. Hardware-based
optical cryptosystems can generate enormously longer secret keys and enable
encryption at light speed, but most reported optical methods, …
