Paper Abstract
A watermarking scheme is proposed based on optical asymmetric cryptography using double random phase encoding in
the gyrator transform domain. It is based on the phase and amplitude truncation during the encryption process. The
scheme is validated through computer simulations showing the scheme's sensitivity to decryption keys and orders of the
gyrator transform. The occlusion and noise attacks have also been analysed. The proposed scheme is significantly
resistant to both these attacks.
