Biometric techniques

• Biometric


  A physical characteristic such as fingerprints, facial images, irises, and voice
• Biometric scanners


  • Improvements in technology have made their use increasingly common
  • Recognition techniques have become more and more reliable
• Biometric spoofing


  A method of fooling biometric scanners
• Iris recognition


  • One of the most secure forms of authentication
  • The iris is well protected by the cornea
• Fingerprints


  • Can be damaged by cuts
  • Easier to spoof as it is fairly easy to obtain copies
• Uses of fingerprint recognition

  • Accessing phones and computers
  • Authorising small payments
• Uses of iris recognition

  • Major part of airport security systems
• Voice recognition


  • An emerging use of biometrics
  • Our voices have unique characteristics such as length of the vocal tract, pitch, and accent
• Users of voice recognition

  • Banks
  • Insurance companies
• With all biometric systems, it is important that users opt in and consent to the storage and processing of their personal data
