Abstract
A system for authenticating items includes: a processing unit for generating indicia for imprints to be applied to items and authenticating imprints applied to items, each indicium including a cryptographically encoded component; at least one item printing station for printing imprints on items as generated by the processing unit; and at least one item presentation station to which items are presented in authenticating the same. The item presentation station is configured to transmit data relating to the indicium on an item presented thereto to the processing unit, and to receive an authentication message in dependence upon whether the indicium is determined to be valid or invalid.
