  • a user when a user seeks to verify their identity they swipe their swipe card through the contact card reader 112.
  • the data read by the contact card reader 112 from the swipe card is then simultaneously transmitted to both the existing access control system 110 and the biometric identity variation system 10 where each system then processes the data to determine whether access should be granted. Only if both systems authorise the user's entry is the user then able to enter the access controlled area.

  • Types of cameras and LEDs other than those described, can be used. Additionally, substitute arrangements may be used, such as implementing an analogue camera arrangement with means to digitally image the resulting picture or including fluorescent or incandescent light bulbs in place of the LEDs.
  • the biometric access control systems may implement a further level of access control through the inclusion of access privilege information as part of the identifying information. In such arrangements, if the user does not have the required access privilege to access the area beyond the door, that area will remain closed to the user even in a situation where the user can properly verify their identity.
  • External interface connector 38 can be used to connect to a mobile computer for purposes of modification of the biometric database 36 contained within the biometric identity verification system 10.

Abstract

L'invention porte sur un système d'identification biométrique constitué des éléments suivants : moyen de traitement ; moyen d'identification d'utilisateur permettant de recueillir des données d'identification utilisateur ; au moins un lecteur biométrique ; et une base de données biométriques. Chaque entrée de la base de données biométriques contient des relevés biométriques de référence pouvant être effectués par au moins un lecteur biométrique, ainsi que des données d'identification utilisateur. En cours d'utilisation, le dispositif d'identification d'utilisateur fait l'acquisition des données d'identification utilisateur qu'il achemine au dispositif de traitement. Le dispositif de traitement effectue alors la comparaison des données d'identification utilisateur prélevées avec celles contenues dans chaque entrée de la base de données biométriques jusqu'à ce qu'il trouve une entrée dont les données d'identification utilisateur correspondent aux données prélevées. Ensuite, le dispositif de traitement transmet une commande de lecture à la pluralité de lecteurs biométriques pour la prise de relevés biométriques de l'utilisateur puis effectue une comparaison de chaque relevé effectué avec les valeurs biométriques de référence contenues dans l'entrée correspondante. Si la comparaison atteint un niveau de confiance précis et prédéterminé, selon le type de relevé biométrique faisant l'objet de la comparaison, l'identité de l'utilisateur est alors considérée comme étant vérifiée.
