Definitions

  • the present invention relates generally to a method and apparatus for identification of a person and in particular to a method and apparatus for authenticating an identification.
  • Biometrics is the science of automatically identifying individuals based on their unique physiological and behavioral characteristics. Biometric information may be based on unique characteristics of a person's face, iris, voice, fingerprint, signature or DNA. These identification techniques can all be used to authenticate a person's identity from information stored in a database of held on a token as a two dimensional barcode, magnetic stripe, smart card, USB (Universal Serial Bus) device, memory stick or RFID (Radio Frequency Identification) format device.
  • USB Universal Serial Bus
  • RFID Radio Frequency Identification
  • the present invention provides a method and apparatus using a combination of two dimensional and three dimensional biometric template data to authenticate an identification.
  • Figure 1 is a schematic front view of a portable identification device having a fingerprint sensor
  • Figure 2 is a schematic review view of the portable identification device of

  • Figure 6 is a functional block diagram of hardware and software definition for the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • FIG. 1 is shown schematically an identification module 10 having a rugged housing and a touch pad fingerprint sensor 12.
  • the fingerprint sensor 12 is used to obtain fingerprint biometric data.
  • the module has two camera lenses 14 and imaging devices facing the same direction and spaced apart by a predetermined distance.
  • the imaging devices are electronic imaging devices, such as CCD or CMOS imaging devices. Other types of imaging chips may be provided as well. Both imaging devices are operated at the same time to take two images spaced by the predetermined distance. Thus, the imaging devices obtain a stereographic image that includes three dimensional information of the object being imaged.
  • the illumination is provided here by a ring shaped lighting system 16 surrounding each lens.
  • the ring shaped lighting system 16 of a preferred embodiment has a plurality of LEDs in each ring.
  • the LEDs are of two types. First, five visible light LEDs 18 are provided in the ring light system and, second, five IR (InfraRed) LEDs 20 are provided in each ring light system.
  • each ring light system includes ten LEDs to provide illumination to the subject being imaged.
  • the imaging chip either CCD or CMOS
  • Such IR filters are common in commercial imaging systems, such as digital cameras and will not be provided here.
  • the lighting system can use either the visible light, the infrared light or both in obtaining the stereographic images.
  • the stereographic images are input to software to generate two dimensional and three dimensional biometric information about a subject.
  • the biometric information is combined.
  • This information is stored on a data carrier that is provided to a person that has been identified.
  • the data carrier is any of a variety of data carriers, which are referred to as a token, card, or the like.
  • Combined 2D/3D facial biometric template data is read from a token, storage media or other data carrier and compared to live 3D images captured via a ruggedly built handheld computer identification device.
  • the computer identification device is shown in Figure 3. Simultaneous images are sent wirelessly to a central server where software stitching is performed to produce a single 3D image.
  • the 3D image is converted via software to a 3D biometric template.
  • the newly generated template is compared to 3D facial biometric data that is held in the storage media.
  • an extraction process is performed on the 3D image to extract 2D biometric data from the 3D image.
  • the extracted 2D data is compared to 2D biometric data extracted from the storage media.
  • the combination of these two methods results in an authentication (level of match) score being displayed on the handheld computer.
  • Authentication levels can be adjusted up or down depending on a level of security required.
  • the handheld computer operator has the facility to interrogate the score and review either the 2D or 3D results, or both, should there be a discrepancy in the overall results.
  • the operator can also call up and display the original photo image stored at the time of enrollment for additional visual confirmation.
  • an enrollment process proceeds as follows: The enrollment is achieved using either a ruggedly built handheld computer with a twin image capture apparatus or by a 3D (three dimensional) camera connected to a PC.
  • a wireless communication in the preferred embodiment, which communication can include communications according to the 802.1 lb standard, WLAN (Wireless Local Area Network), GPRS (General Packet Radio Service) or CDMA (Code Division Multiple Access).
  • 3D (three dimensional) software is resident on the server to receive the image data.
  • a 3D software process combines the incoming video feeds to produce a live 3D (three dimensional) image.
  • the 3D software then extracts a 3D template.
  • 2D (two dimensional) software extracts a 2D template from the same 3D image source.
  • an authentication process is carried out as follows.
  • the stored template (key) information is read from the card or token.
  • twin images are fed to the server.
  • Both 3D and 2D templates are then extracted from the live feed for comparison with the previously stored card information and the residual template information held on the server.
  • the two scores are then combined and transmitted back to the handheld computer and displayed as a level of confidence in the match.
  • the handheld computer operator can call up either the 3D or 2D information if required. Also at this time the original image taken at the time of enrollment is displayed. (See Figure 4).
  • the biometric information may be updated according to the follows process.
  • the stored template information can be updated seamlessly, if the authentication levels drop below a preset threshold.
  • Re-writable token media can be updated seamlessly whereas in the case of two dimensional barcode ID there would be a need to reprint.
  • a control apparatus is connected to the two cameras and a fingerprint sensor as inputs.
  • a control for the lighting is provided.
  • a display is connected to the control through a device controller.
  • Data input to the device is possible through a card reader or radio frequency device reader.
  • Image capture and processing software provides 2D and 3D processing, 3D capture and iris identification.
  • a communications port through a wireless TCP/IP connection, for example, provides data to and from a server or other network.
  • the identification accuracy can be increased.
  • the use of two separate facial biometric processes significantly increases the overall accuracy of the authentication when measured against either of the biometric methods used individually. Similar improvements in accuracy can be achieved by combing either the 2D/3D facial with fingerprint or other biometric data.
  • Facial biometrics includes more than just surface features of the face. It includes iris, wrinkling, scarring, wounds, tattoo (and tattoo removal) patterns and features including subdermatological patterns, pores and other dermato logical depth and variation, hair features such as thickness, baldness patterns as well as hair chemical composition, ears, teeth cavity and tooth growth patterns/dentures/gums and other features internal to the face including the mouth, nose and eyes, ears external and internal to the body, coloring, cranial and bone structure and pattern, internal anatomy, brain features, brain activity, pheromone (i.e., various odors of the person or object), salinity and chemical patterns, body temperature, motion patterns such as a specific tick or Parkinson's type shake, walking limp, nervous habit (such as scratching, tapping, knee-shaking), aura-type variations, and other features and characteristics. All of these features and characteristics can be detected and captured non- invasively as well. These are all included within the scope of the invention.
  • the identification and authentication method and system includes linked databases that might separately contain information on any one, or more than one, such feature named above.
  • the mobile device can include identification and authentication of bar coded or other stored information in more than one database.
  • These multiple databases might include iris identification in one database and other facial identification in a second, third or more databases.
  • the present system and method is designed not only to operate in normal (e.g., daylight, laboratory, good weather condition at sea level, at one atmosphere, etc) conditions.
  • the system is mobile so that it will be utilized in a wide range of environments. These include space programs, subterranean, underwater, sea water/fresh water/brine water, excessive heat and cold, and under compromised or chemical/radiological environments including bio hazardous environments that present imperfect conditions.
  • the ruggedly built housing and the components are selected and constructed to withstand these harsh environmental conditions and so permit operation of the device wherever needed.
  • the present device includes a system or method that can operate under the harsh/abnormal environment including wet (sea fresh/brine water), hot cold temperature conditions; chemically or radiologically- or biologically-tainted or compromised environment; excessive dust/dirt (including desert-type), wind, pressure and vibration environments.
