Abstract

We introduce a system for optical encryption of 2D page- oriented data. The system used is an anamorphic optical correlator. The data is scrambled by means of a code on a 1D hologram which is also used for descrambling the data. The principle is somewhat similar to a 2D Rubik cube or a 2D combination lock: the page is sliced first into horizontal slices which are shifted laterally with wraparound. The same process is then carried out vertically and repeated. Computer simulations and optical results are presented.
