摘要： Disclosed are fibers which contain identification fibers. The identification fibers can contain a one or more of chemical markers and one or more distinct features, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The chemical markers and distinct features can be representative of specific supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer. The disclosed embodiments also relate to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and distinct features and correlating the chemical markers and distinct features to manufacturer-specific taggants to determine supply chain information.

摘要： 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.

摘要： The invention provides a method of marking an item with naturally-derived or synthetic non-natural polymeric marker molecules, such as a DNA or Peptide marker in conjunction with optional visible or rapid scan reporters for authenticating or tracking, in which the method includes providing an item for marking, and applying a medium including a DNA marker to the item. The invention further provides methods for stably binding and immobilizing activated deoxyribonucleic acid onto objects and substrates. The method includes exposing the deoxyribonucleic acid to alkaline conditions, and contacting the deoxyribonucleic acid to the object or substrate. Also provided are methods for increasing the recoverability of taggants from an object. The methods include the steps of incorporating a taggant into a solution; mixing the solution including the taggant with a perturbant to form a first perturbant taggant solution; mixing the first perturbant taggant solution with a polymer to form a second perturbant taggant polymer solution; and applying the second perturbant taggant polymer solution to at least a portion of the object to form a taggant-coated object. The invention also provides a method of marking an item with a DNA marker for authenticating or tracking, in which the method includes providing a medium including a DNA marker, and molding the medium including the DNA marker to provide all or part of the item. The DNA marker encodes information unique to the item and/or the model of the item as desired.

摘要： Paper notes used as a monetary currency are deuterated. The level of deuteration while not complete, is high. For U.S. currency the level of deuteration is at least 0.1 mg of deuterium for each one dollar in value of the currency note, and preferably at least 0.3 mg. Use of X-ray or gamma ray interrogation with a beam energy above 2 MeV produces a nuclear reaction releasing a neutron from the deuterium nucleus. If the currency is in large concentrations, e.g. $100,000 or more, the neutrons emitted by this reaction are reliably detectable. The deuteration occurs in the cellulose fibers forming the currency. To resist an exchange of hydrogen atoms for deterium atoms, the deuterium atoms can be used in the formation of synthetic cellulose where the deuterium is more deeply buried within the cellulose molecule than in naturally occurring cellulose. The deuterated synthetic fibers are blended with natural, non-deuterated fibers to form the paper. The currency can also include a mechanism, such as dye, to signal attempts to use solvents or otherwise facilitate any such hydrogen substitution.

摘要： An improved scratch card instant lottery ticket includes micro-encapsulated chemical reactants which, when released, irreversibly form one of a visual color change or a fluorescence signature at a location of the card. Both the visual color change and fluorescence signature indicate that the location has been played. Scratch cards are also marked to indicate that they have been read. Cards are marked by either automatically activating chemical reactants to form a visual color and a fluorescence signature, heating a thermofluorescent material to alter a fluorescence signature, or applying a heat-responsive material to the scratch card in such that when the identification code is read, an altered material is detected. Also taught are a method and apparatus for evaluating the scratch card to determine which locations on the card have been played. The evaluation method includes the steps of: (A) directing over at least two angles a beam of light emitted from a light source to impinge on a location of the card; (B) detecting for each of the at least two angles a component of the beam of light as it leaves the location; (C) measuring scattering angles for the location from the components detected leaving the location over the at least two angles; and (D) comparing the scattering angles of the location to a predetermined threshold, and when the angles exceed the threshold identifying the location as unplayed.

摘要： A pressure and heat-sensitive composition comprising chromogen-containing pressure-rupturable microcapsules and heat-sensitive color developer useful for verification of document authenticity system when applied as a localized coating on documents, such as checks and prescriptions. Quickly striking the chromogenic composition with a fingernail or blunt object to generate pressure and heat in the coating produces a colored image by friction. The chromogenic composition possesses a fugitive characteristic, whereby the colored image gradually disappears and can be made to reappear when the chromogenic coating is again subjected to external pressure and heat. This feature can be used for repeated verification of the authenticity of the document.
