Title: Personal authentication deviceApplicant: Raytheon Co (US); Ehlers Gerald L (US); Lepple Charles F (US); Watts Aaron D (US)Patent number: WO2005096214Publication date: 13 October 2005

An identification card includes a fingerprint sensor, an antenna, a dual- mode radio frequency modulator connected to the antenna and digital circuitry having memory to store a digital word, the digital word including a representation of a fingerprint initially scanned by the fingerprint sensor to identify an individual associated with the identification card. The identification card further includes a control processor connected to the digital circuitry and the radio frequency modulator to communicate a signal to the antenna indicative of a successful match between the fingerprint initially scanned by the fingerprint sensor and newly scanned fingerprint. With such an arrangement, a technique is provided biometrically authenticating the identity of an individual passing through a checkpoint without requiring the individual to stop or exit a vehicle and eliminates the need for a central database of biometric data on individuals.

Title: Intelligent identification cardApplicant: IVI Smart Technologies Inc. (US)Patent number: MD20050099Publication date: 30 September 2005

The invention relates to a personal identification card possessing high security degree. The identification card includes an on-board memory for stored reference data, an on-board sensor for capturing live biometric data, an on- board microprocessor for comparing the captured biometric data with corresponding stored reference data and for generating a verification message only if there is a match within a predetermined threshold; and means for communicating the verification message to an includes data driven multi- processor chip on the card to provide a hardware fire wall that both encrypts and isolates the biometric data stored on the card, thereby providing substantially greater protection against unauthorized alteration of the stored data.

Title: Multi-biometric finger sensor using different biometrics having different selectivities and associated methodsApplicant: Authentec Inc. (US); SetlakDale R (US)Patent number: WO2005078636Publication date: 25 August 2005

A multi-biometric finger sensor may sense different biometric characteristics that have different matching selectivities and that have at least a known spatial relationship. The sensor may include an integrated circuit substrate for receiving a user’s finger adjacent thereto, and a first set of biometric sensing pixels on the substrate for sensing a first finger biometric characteristic to generate first finger biometric characteristic data having a first matching selectivity. The sensor may also include a second set of biometric sensing pixels on the integrated circuit substrate for sensing a second finger biometric characteristic different than the first finger biometric characteristic to generate second finger biometric characteristic data with a known spatial relationship to the first fingerprint characteristic data. The second finger biometric characteristic data may have a second matching selectivity less than the first matching selectivity.

Title: Identity verification system with self- authentificating cardApplicant: Simon Rudy (US)Patent number: WO2005083532Publication date: 9 September 2005

An identity verification system that includes a self-authenticating identity card and a card reader. The self- authenticating card has a programmable microchip with data pertaining to the authorized card bearer, including data for a stored biometric feature, such as a fingerprint, a retinal scan, a voice print, a DNA sequence, etc. The card also includes a biometric sensor that senses an applied biometric feature and a data lock that releases data upon determination of a match between the stored and the applied biometric features. In order to self-authenticate the card, the card bearer must provide the applied biometric feature. For example, the card bearer applies a finger tip to the sensor, if the applied biometric feature is a fingerprint. If the data match, the data lock transmits data stored on the card to the card reader for processing.

Title: Finger biometric sensor with sensor electronics distributed over thin film and monocrystalline substrates and related methodsApplicant: Authentec Inc. (US)Patent number: US2005110103Publication date: 26 May 2005

A finger biometric sensor may include a thin film substrate, a thin film transistor (TFT) layer on the thin film substrate, and an array of electric field sensing electrodes adjacent the TFT layer for receiving a finger adjacent thereto. The TFT layer may include a plurality of TFTs defining a respective TFT amplifier stage for each electric field sensing electrode. The sensor may further include a finger excitation electrode adjacent the array of electric field sensing electrodes, and at least one integrated circuit adjacent the thin film substrate. The integrated circuit may include a monocrystalline substrate and processing circuitry adjacent the monocrystalline substrate and connected to the TFT amplifier stages.

Title: Multi-biometric finger sensor including electric field sensing pixels and associated methodsApplicant: Authentec Inc. (US)Patent number: US2005089202Publication date: 28 April 2005

A multi-biometric finger sensor includes a plurality of electric field fingerprint sensing pixels on an integrated circuit substrate for sensing an image of the user’s finger, and at least one other finger biometric characteristic sensor on the integrated circuit substrate for sensing a finger biometric characteristic different than the image of the user’s finger. Each of the electric field fingerprint sensing pixels may include an electric field sensing electrode, a guard shield surrounding the electric field sensing electrode, and an amplifier connected between the electric field sensing electrode and the guard shield. The sensor may also include a finger drive electrode adjacent the plurality of electric field sensing pixels, and a processor connected to the electric field fingerprint sensing pixels and the at least one other finger biometric characteristic sensor.
