What are the advantages of using a chip card for biometric authentication?
In biometrics, possession of a chip card combined with biometric methods further increases security in a verification. Not only are reference features saved on the chip card, but also identity data of the user. For authentication, the card plus entry of the biometric feature is necessary. The following advantages result: • entry of a user ID via keypad is unnecessary • no central data base storing reference features is necessary • compromisation of the biometric feature without the possession of the card is not critical • when using a chip card with an integrated crypto processor and feature matching device, systems allowing possible compromisation by decoding a readout are rendered impossible. • if a normal chip card is stolen, it must be blocked and a new card issued. With a crypto card on the other hand, only the saved, non displayed secret key must be changed. Still high er security is achieved when using a crypto card which integrates biometric sensors in the card. This offers mor
