Title: Detection of counterfeit currency

Abstract

A method of detecting counterfeit currency by contacting the currency to be tested with near infrared beams in the spectrum below 1250 namometers, measuring reflectance of the near infrared beams and comparing the reflectance values with those from genuine currency.

Test circuits for integrated circuit counterfeit detection

Patent Helinski, Ryan; Pierson, Lyndon G.; Cole, Edward I.; ...

Described herein are various technologies pertaining to identifying counterfeit integrated circuits (ICs) by way of allowing the origin of fabrication to be verified. An IC comprises a main circuit and a test circuit that is independent of the main circuit. The test circuit comprises at least one ring oscillator (RO) signal that, when energized, is configured to output a signal that is indicative of a semiconductor fabrication facility where the IC was manufactured.

Detection of counterfeit and compromised devices using system and function call tracing techniques

Patent Babun, Leonardo; Aksu, Hidayet; Uluagac, A. Selcuk

Frameworks, methods, and systems for securing a smart grid are provided. A framework can include data collection, call tracing techniques, and preparing call lists to detect counterfeit or compromised devices. The call tracing techniques can include call tracing and compiling all system and function calls over a time interval. The framework can further include data processing, in which a genuine device is identified and compared to unknown devices. A first statistical correlation can be used for resource-rich systems, and a second statistical correlation can be used for resource-limited systems. Threats of information leakage, measurement poisoning and store-and-send-later can be considered.

Counterfeit-resistant materials and a method and apparatus for authenticating materials

Patent Ramsey, J Michael [Knoxville, TN]; Klatt, Leon N [Oak Ridge, TN]

Fluorescent dichroic fibers randomly incorporated within a media provide an improved method for authentication and counterfeiting protection. The dichroism is provided by an alignment of fluorescent molecules along the length of the fibers. The fluorescent fibers provide an authentication mechanism of varying levels of capability. The authentication signature depends on four parameters, the x,y position, the dichroism and the local environment. The availability of so many non-deterministic variables makes production of counterfeit articles (e.g., currency, credit cards, etc.) essentially impossible Counterfeit-resistant articles, an apparatus for authenticating articles, and a process for forming counterfeit-resistant media are also provided&
