A method of authenticating products or packaging by analyzing key ingredients on products or on product packaging is disclosed. Light-sensitive compounds can be used to identify the product or product packaging. The product or product package may include visible or invisible ink containing a particular light-sensitive compound. One or more light-sensitive compounds and ink, if used, may be printed in one or more locations on the product or product packaging to produce an authentication mark to inhibit inadvertent or intentional removal of the mark, thereby rendering the mark tamper-resistant. The mark is sealed to isolate the mark from the environment. A device may be used to irradiate the mark and read light absorption or emission. A controller determines the authenticity of the mark by comparing the emitted or absorbed properties to a standard.
本发明公开了一种通过分析产品或产品包装上的关键成分来鉴定产品或包装的方法。光敏化合物可用于识别产品或产品包装。产品或产品包装可包括含有特定光敏化合物的可见或不可见油墨。可以在产品或产品包装上的一个或多个位置印上一种或多种光敏化合物和墨水(如果使用),以产生验证标记,防止无意或有意去除标记,从而使标记具有防篡改功能。标记被密封起来,使标记与环境隔离。可使用一个装置照射标记并读取光吸收或发射。控制器通过将发射或吸收特性与标准进行比较来确定标记的真伪。
