    摘要： A method and apparatus for testing the porosity of an object, such as a secure instrument having a substrate, visual data, and a security feature, is disclosed. The method and apparatus include a fluid source, a gasochromic material, an excitation source configured to excite the gasochromic material, and a detection device configured to sense changes in emissions from the gasochromic material after it is contacted with the fluid and excited by the excitation source. The object is configured to fit within a space between the fluid source and the gasochromic material such that when the fluid is emitted from the fluid source, at least a portion of the fluid is configured to flow through the object before contacting the gasochromic material.

    摘要： Systems and methods for document and product authentication using a variety of absorption and emission signatures are disclosed. Emission signatures in the form of florescent or phosphorescent coatings, inks and substrates are used for authentication and protection of items such as documents, currency, and secondary packaging for tobacco, luxury goods and pharmaceuticals. Spectrally overlapping absorption and emission materials are combined to provide a unique spectral fingerprint detectable by a scanner.

    摘要： Systems and methods of providing a covert security marking for items such as documents, packaging, credit cards, and other valuable goods to combat the steady increase in forgery, counterfeiting, and other fraudulent activities is presented. A spectrally narrow, near infrared ink system serves as the basis of a covert security feature for items of value. Alternatively, or in combination, metal oxides having a substantially narrow absorption band and a maximum absorption wavelength of electromagnetic radiation in the near infrared range are also utilized.

    摘要： Disclosed are methods and apparatus for at least one of authenticating, sorting or counting documents, as well as security structures (12) contained within documents and documents (10) containing security structures. A security device or structure (12) includes an optical gain medium and a structure having boundaries that impart an overall geometry to the structure that, in combination with at least one material property of the structure, supports an enhancement of electromagnetic radiation emitted from the gain medium for favoring, in one embodiment, the creation of at least one mode that enhances an emission of electromagnetic radiation within a narrow band of wavelengths. Suitable shapes for the structure (12) comprise elongated, generally cylindrical shapes such as filaments (12B), a sphere shape, a partial-sphere shape, a toroidal shape, a cubical or other polyhedral shape, and a disk shape (12A). The structure (12) preferably comprises at least one of a monolithic structure or a multi-layered structure (12C) or an ordered structure that may provide for distributed feedback. The security device (12) may be incorporated in currency, a passport, a lottery ticket, a negotiable security, a credit or debit card, or any substrate for which it is desired to authenticate, count, encode, sort, or verify.

    摘要： A system and method for authentication of secure products is disclosed. The security feature contains a first component in the form of an emitter (28,210;216) capable of emitting light in response to external pump light. The security feature also contains a second component in the form of a taggant (24; 218) that absorbs light in a spectrally narrow range compared to the broader excitation spectrum of the first material. In this manner the emitter ( 28,210; 216) and taggant (24; 218) work in combination with one another to create an emission response significantly dependent on the illumination wavelengths and unique to the specific combination of the components. The emitter ( 28,210; 216) and taggant (24;218) can be in the form of a mixture. Further the emitter ( 28,210; 216) and taggant (24;218) may be applied in close proximity to one another, such as within two separate coating layers on a suitable substrate (22).
