We present a double image encryption scheme by using random pixel exchanging and phase encoding in gyrator domains. Two original images are regarded as the amplitude and …
We discuss the principle, and experimentally demonstrate an optical encryption system that uses the polarization of light to encrypt a binary image. The encryption is done by an …
