Description
本出願は、2015年2月19日に出願された“Methods for Securing Invisible 2D Barcodes and Printed Images”と題する米国仮特許出願62/118,206、及び2015年3月12日に出願された“Methods for Securing Covert Barcodes and Printed Images”と題する米国仮特許出願62/132,297の利益を主張し、これら米国仮特許出願はいずれもその全体が本明細書に完全に含まれるかのように本出願に組み込まれるものとする。
本発明は、広義には、セキュアなバーコードを有する文書、及びそれら文書の作成システムおよび方法に関連する。本発明は、具体的には、蛍光バーコードを有する文書であって、当該蛍光バーコードの偽造からの保護が、その蛍光性に加えて、セキュリティ特徴によってさらに強化された文書に関連する。
バーコードは物体を分類、識別するため長年にわたって用いられてきた。バーコードは近年まで一次元のものであり、その幅及びお互いの間の間隔が可変的である垂直な線のみで構成されていた。長い間、このようなバーコードはバーコードリーダによってしか読み取りができず、したがって不正な読み取りや偽造に対してある程度のセキュア性を有していた。しかし、光学技術及びコンピュータ技術が進歩するにつれて、バーコードを読み取り、解釈する能力を有する装置(例えばスマートフォンやプリンタ/スキャナシステム)の数が増加した。
