Abstract

This disclosure relates generally to document validation system. More specifically, this disclosure relates to a phosphorescent decay imaging implementation within a fraudulent detection or other system. Commercially available fraudulent document detection systems often include sensors (optical/magnetic/capacitive/inductive) that detect response of the document to applied optical/magnetic/capacitive/inductive pulses. These types of fraudulent document detection systems can be used in a variety of ways, such as in passport and monetary banknote handling systems. A system comprising: a delay/pulse generator configured to selectively delay initiation of imaging after excitation of light source to image phosphorescent decay; and at least one imaging sensor taking images of the document at either predetermined or arbitrary delay; at least one light source to excite the phosphorescent ink in the document wherein the at least one computer/tablet/phone/processor/controller compares the phosphorescent decayed images with reference phosphorescent decayed images to determine validity of the document.

[3]
This disclosure provides a phosphorescent decay imaging implementation within a fraudulent document detection system or other system.

[4]Before undertaking the DETAILED DESCRIPTION below, it may be advantageous to set forth definitions of certain words and phrases used throughout this patent document. The term "couple" and its derivatives refer to any direct or indirect communication between two or more elements, whether or not those elements are in physical contact with one another. The terms "transmit," "receive," and "communicate," as well as derivatives thereof, encompass both direct and indirect communication. The terms "include" and "comprise," as well as derivatives thereof, mean inclusion without limitation. The term "or" is inclusive, meaning and/or. The phrase "associated with," as well as derivatives thereof, means to include, be included within, interconnect with, contain, be contained within, connect to or with, couple to or with, be communicable with, cooperate with, interleave, juxtapose, be proximate to, be bound to or with, have, have a property of, have a relationship to or with, or the like. The term "controller" means any device, system or part thereof that controls at least one operation. Such a controller may be implemented in hardware or a combination of hardware and software and/or firmware. The functionality associated with any particular controller may be centralized or distributed, whether locally or remotely. The phrase "at least one of," when used with a list of items, means that different combinations of one or more of the listed items may be used, and only one item in the list may be needed. For example, "at least one of: A, B, and C" includes any of the following combinations: A, B, C, A and B, A and C, B and C, and A and B and C.

[5]Those of ordinary skill in the art should understand that in many if not most instances, such definitions apply to prior as well as future uses of such defined words and phrases.
