20160377418 | System for Identifying and Duplicating Master Keys - A system for duplicating a master key includes a mechanism for receiving and positioning a master key. The master key defines a major key axis and an intermediate key axis along which a key blade variably extends, and a minor key axis along a key thickness. Optical path components direct a light beam along the minor key axis. The light beam impinges upon the key blade. A portion of the light beam traverses the key blade. A detector receives the portion of the light beam that traverses the key blade. An apparatus imparts relative motion along the major key axis between the light beam and the master key. The light beam scans along the major key axis of the master key. A processor receives a signal from the detector as the beam scans along the major key axis and generates information usable for defining the machining of a duplicate key. | 12-29-2016 |
20160377423 | SPATIAL-LIGHT-MODULATOR-BASED SIGNATURES OF INTRINSIC AND EXTRINSIC SCATTERING SURFACE MARKERS FOR SECURE AUTHENTICATION - Unique methods and systems are introduced herein for the determination of unique spatial light modulator based optical signatures of intrinsic and extrinsic scattering surface markers. These techniques can be used to authenticate semiconductor components and systems at various stages during the manufacturing process by measuring and cross correlating the surface marker's unique optical signature. In addition, these techniques can be used with extrinsic surface markers which are added to existing hardware (e.g. containers, locks, doors, etc.). These markers can then be measured for their unique optical signatures, which can be stored and used at a later time for cross-correlation to authenticate the surface marker and verify the hardware's provenance. | 12-29-2016 |
