Anti-counterfeit edible integral lens array for pharmaceuticals

描述（由申请人提供）：我们建议证明使用UV激光标记技术和可食用的整体透镜阵列图像编码药物片剂作为防伪设备的可行性，其中单个片剂可以使用类似全息图的标记进行唯一编码，该标记具有匹配的，不可食用的，类似全息图的标记放置在瓶子外面或作为盖子周围的安全密封。用于食用透镜阵列的材料被列入FDA公认的安全（GRAS）清单。所述整体透镜阵列提供了一种读取标记的方法，但不能轻易地用于改变所述标记。这提供了可追溯性以及类似于公钥加密的安全性。除了对公共安全有利之外，这种能力还可以被FDA用作药品库存的标准化方法。

DESCRIPTION (provided by applicant): We propose to demonstrate the feasibility of encoding pharmaceutical tablets using UV laser marking technology and edible integral lens array imagery as an anti-counterfeit device where individual tablets can each be uniquely coded with a hologram-like marker with a matching, non-edible, hologram-like marker placed on the outside of the bottle or as a security seal around the cap. Materials to be considered for the edible lens array are listed on the FDA's generally recognized as safe (GRAS) inventory. The integral lens array provides a means to read the markings but cannot readily be used to alter the markings. This provides traceability as well as security analogous to public key encryption. In addition to the benefit to public safety, such capability could be used by the FDA as a standardized method for pharmaceutical inventory. PUBLIC HEALTH RELEVANCE: The successful demonstration of the feasibility of the pharmaceutical laser marking method proposed here will, on further development, provide a means to fight pharmaceutical counterfeiting and thereby safeguard public health.
