20090042191 | SYSTEM AND METHOD FOR SECURE DOCUMENT PRINTING AND DETECTION - A method for authenticating and verifying an item to be genuine is described. The method for authenticating the item comprises applying a particular nucleic acid material associated with a particular sequence of nucleic acid bases to ink within an ink cartridge or a toner compound within a toner housing. The method also comprises collecting a sample of either the ink or toner compound and verifying the ink or toner is genuine by detecting the particular nucleic acid material. | 02-12-2009 |
20090075261 | SYSTEM AND METHOD FOR AUTHENTICATING TABLETS - A method for authenticating and verifying a pharmaceutical item to be genuine is described. The method for authenticating a tablet comprises applying a particular nucleic acid material associated with a particular sequence of nucleic acid bases to a tablet or capsule. The method also comprises collecting a sample of the tablet and verifying the tablet is genuine by detecting the particular nucleic acid material. | 03-19-2009 |
20100285985 | Methods and Systems for the Generation of Plurality of Security Markers and the Detection Therof - This invention pertains to methods for generating large quantities of DNA security markers by combinatorial variation techniques using polymorphic fragment length DNA for unique identification security marker applications such as explosive ink used in dye/smoke pack and cash carrying boxes. | 11-11-2010 |
20140099643 | USE OF PERTURBANTS TO FACILITATE INCORPORATION AND RECOVERY OF TAGGANTS FROM POLYMERIZED COATINGS - The invention provides 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. Methods for authentication of a taggant marked object are also provided. | 04-10-2014 |
20140102899 | PLASMA TREATMENT FOR DNA BINDING - The invention provides a composition including DNA bonded to a plasma-treated surface, the plasma can be any suitable plasma, such as an argon plasma, a compressed air plasma, a flame-based plasma or a vacuum plasma. Surfaces treatable by the methods of the invention include ceramic, metal, fabric and organic polymer surfaces. The DNA can be any DNA, such as a marker DNA, which can be linear or circular, single-stranded or double stranded and from about 25 bases to about 10,000 bases in length. Also provided is a method of binding DNA to a surface, including the steps of exposing the surface to a plasma to produce a plasma-treated surface; and applying DNA to the plasma-treated surface to produce surface bound DNA on the treated surface. A system for binding DNA to a surface is also disclosed, the system includes a plasma generator adapted to treating a surface with a plasma to produce a plasma-treated surface; and an applicator containing DNA adapted to applying DNA to the plasma-treated surface to produce surface bound DNA on the plasma-treated surface. | 04-17-2014 |
20140272097 | DNA MARKING OF PREVIOUSLY UNDISTINGUISHED ITEMS FOR TRACEABILITY - The invention provides a method of marking an item with a 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 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. | 09-18-2014 |
20150083797 | VERIFICATION OF PHYSICAL ENCRYPTION TAGGANTS USING DIGITAL REPRESENTATIVES AND AUTHENTICATIONS THEREOF - A verifiably identifiable object that includes a primary taggant encoding a readable encrypted first identifier of the object encrypted by a first method and a secondary taggant encoding a readable encrypted second identifier of the object optionally encrypted by a second method. The primary taggant can be a physical identification taggant, such as DNA including an authentication sequence, and the secondary taggant can be a digital identification taggant. The digital identification taggant encodes information validating the physical identification taggant, such as by referencing information embodied in the physical taggant, e.g. the defined sequence within the DNA. Also included is a method and system for identification and/or authentication of an object that includes a primary taggant encoding a readable encrypted first identifier of the object encrypted by a first method and a secondary taggant encoding a readable encrypted second identifier of the object encrypted by a second method. | 03-26-2015 |
20150107475 | DNA MARKING OF PREVIOUSLY UNDISTINGUISHED ITEMS FOR TRACEABILITY - 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. | 04-23-2015 |
