Abstract
A number of method have been recently proposed
in the literature for the encryption of 2-D information
using optical systems based on the fractional Fourier fransform,
FRT. In this paper a brief review of the methods proposed
to date is presented. A measure of the strength/robustness
of the level of encryption of the various techniques
is proposed and a comparison is carried out between the
methods. Optical implementations are discussed. Robustness
of system with respect to misalignment and blind decryption
are also discussed.
