We present a basic optical encryption architecture that admits several cryptography applications based on multiplexing Users can decrypt different private images from the same encrypted Image a superuser can have a key that decrypts all encrypted images and multiplexed images can be encrypted with different levels of security This system is presented in the context of a general framework of optical encryption application development We illustrate with a real-world three dimensional scene captured with digital holography and encrypted using the fractional Fourier transform where different users have access to different three-dimensional objects in the scene (C) 2010 Elsevier B V All rights reserved
