ACCESS CONTROL FOR ACCESS RESTRICTED DOMAINS USING FIRST AND SECOND BIOMETRIC DATA

摘要

A method for granting access for a user to a domain which is subject to an access restriction, wherein the user belongs to a group of one or more user shaving an access privilege in relation to the domain. The method comprises acquiring a first set of biometric data associated with the user. A first identification is successful if a comparison of the first set of biometric data to previously acquired data relating to the user, or to the group of users, indicates that the user belongs to the group. The method also comprises acquiring a second set of biometric data associated with the user responsive to the first identification being successful. A second identification is successful if a comparison of the second set of biometric data to previously acquired data relating to the user indicates that the user has the access privilege.
