Abstract: the invention provides a composition having laser engraving properties, comprising a host material and a laser enhancing additive. The host material comprises a material, such as a polymer, modified by a first process, whereby the host material as modified by the first process has increased thermal conductivity as compared to the host material before the first process. The laser enhancing additive comprises a first quantity of at least one of copper potassium iodide (CuKI3), Copper Iodide (CuI), potassium iodide (KI), sodium iodide (NaI), and aluminum iodide (AlI), and a second quantity of at least one substance selected from the group consisting of zinc sulfide (ZnS), barium sulfide (BaS), alkyl sulfonate, and thioester.

Abstract: The invention relates to identification documents, and in particular to providing optically variable personalized data to identification documents. In one implementation, we provide an identification document comprising a document layer and a first indicium. The document layer comprises a material capable of being printed by a thermally transferable optically variable ink. The first indicium is printed on the document layer and comprises personalized data and printed to the document layer by a thermally transferred optically variable ink. The first indicium may be printed to the document layer by disposing a thermally transferable optically variable ink in a mass transfer panel of a printer ribbon adapted for use in a dye diffusion thermal transfer printer, and printing the first indicium as part of a mass transfer printing process.

Abstract: The present invention relates generally to monitoring and providing information regarding usage or presentment of a driver's license, passport, or other government-issued identification documents. One claim recites: a method of operating a data repository including storing data relating to use or presentment of a person's identification credential in first and second different contexts; analyzing the data for evidence of fraudulent usage based on at least predetermined criteria; and if there is evidence of fraudulent usage, notifying the person to the fraudulent usage. Another claim recites: obtaining information from a government-issued identification document for a person, the information initially gathered from the government-issued identification document during presentation at a first location; providing the information to a data center or data repository; and providing a notification to the person concerning said presentation, the notification including data identifying the first location.

Abstract: According to one aspect, an air travel agent who reviews photo IDs of prospective travelers is advised by an expert system that directs the agent to give certain travelers more or less (or different) scrutiny, depending on the type of photo ID they present (e.g., depending on the jurisdiction from which their driver's license was issued). The system relies on a database in which historical incidents of fraud associated with different types of identification documents are logged, thereby serving as a resource by which future frauds might be better identified. Events that may signal increases in fraud beyond historical norms for particular types of ID documents, such as reported thefts of security laminates or other consumables used in their production, can also (or alternatively) be tracked in the database, and considered by the expert system. Such techniques allow security personnel to focus their efforts where they will do the most good.
