New layout for the access control system based on joint transform correlator (JTC) is presented. The carrier-key should consist of several tested holograms. Each of the hologram stores a part of entire image, stored in the reference hologram. Image domain JTC is used to match the images retrieved from the holograms. Being recorded and retrieved, and images provides correlation peaks with special positions, with a strict dependence on the tested and reference holograms mutual shifts. The optical signal transforming is considered by means of mathematical analysis. The experimental results corresponded with computer simulations are presented.
