  Encrypted markers that are not readily detectable can be revealed by treatment with a specific reagent used as a developer to reveal a readily detectable physical property of the marker, such as a characteristic fluorescence emission after excitation with a particular excitation wavelength, or to reveal a visible color. The encrypted marker can be developed in situ, or a sample can be removed by brushing, scraping, swabbing or scratching the marked object or item and developing the encrypted marker or a sample thereof with the appropriate developer to reveal an overt marker or optical signal. The encrypted marker may include a DNA taggant.

  不易检测的加密标记可以通过使用特定试剂处理来揭示，该试剂用作开发剂以揭示标记的易检测物理特性，例如在特定激发波长下激发后的特征荧光发射，或者揭示可见颜色。加密标记可以在原位中开发，或者可以通过刷、刮、拭或划痕标记的物体或物品来移除样品，并用适当的开发剂开发加密标记或其样品，以揭示明显的标记或光学信号。加密标记可能包括DNA标记剂。
