일부 예에서, 광학 활성 물품은 재귀반사성 기재; 재귀반사성 기재에 배치된 적어도 하나의 보안 요소; 재귀반사성 기재에 배치된 물품 메시지를 포함하며, 적어도 하나의 보안 요소는 가시광 스펙트럼 밖에서 검출 가능한 유효성 검사 정보를 포함하고, 물품 메시지와 적어도 하나의 보안 요소의 유효성 검사 정보의 조합은 광학 활성 물품이 위조품인지를 나타낸다.

    The present invention relates to a method comprising receiving, by a computing device (116) and from an image capture device (102), an image (109) of an optically active article (108) that is based on light captured under a particular lighting condition, wherein the optically active article (108) includes at least one security element (132) and an article message (126), in response to receiving the image (109), determining, by the computing device (116), validation information that is detectable under the particular lighting condition from the at least one security element (132), determining, by the computing device (116), whether the optically active article (108) is counterfeit based on whether a combination of the article message (126) and the validation information of the at least one security element (132) is valid, and performing, by the computing device (116) and based on whether the optically active article (108) is counterfeit, one or more operations, wherein the article message (126) includes one or more encoding units (600) embedded within one or more symbols that comprise the article message (126), the method further comprising determining one or more values represented by the encoding units (600) embedded within the one or more symbols, and wherein determining whether the optically active article (108) is counterfeit based on whether the article message (126) and the combination of the validation information of the at least one security element (132) is valid comprises determining whether a combination of the one or more values represented by the encoding units (600) embedded within the one or more symbols and the validation information of the at least one security element (132) is valid.
