Paper Abstract

In this paper, we present a novel technique for automated remote optical ID tag recognition and verification. The design of distortion-invariant ID tags aims to achieve a correct object authentication even if the ID tag is detected and captured at different distances (i.e. scale variance) or from different views (i.e. rotation variance). Information included in the ID tag is encrypted in order to increase security. We use a fully phase encoded primary pattern and keys by spatial phase multiplexing. This encryption technique is compared with the amplitude-based encoding used in previous works. Experimental results and analysis are presented.
