Abstract
A method for authentication by biometric data, including receiving a biometric data set; evaluating if the received biometric data set is within a reference region, wherein the reference region represents a region associated with a reference biometric data set; evaluating if the received biometric data set is within a blackout region, wherein the blackout region represents a region associated with at least one previously received and positively authenticated biometric data set; and issuing a positive authentication if the received biometric data set is within the reference region, but outside the blackout region.
Claims20
A method for authentication by means of biometric data, the method comprising the steps of:
- receiving a biometric data set;
- evaluating if the received biometric data set is within a reference region, wherein the reference region represents a region associated with a reference biometric data set;
- evaluating if the received biometric data set is within a blackout region, wherein the blackout region represents a region associated with at least one blackout biometric data set that was previously received and positively authenticated;
- and
- issuing a positive authentication if the received biometric data set is within the reference region, but outside the blackout region.
A system for authentication by means of biometric data, the system comprising:
- a biometric data receiver for receiving a biometric data set from a user;
- a memory device for storing reference biometric data sets corresponding to the users of the authentication system and for storing at least one blackout biometric data set for each user, wherein the blackout biometric data set is a data set of a previous and positively authenticated authentication attempt of the respective user;
- wherein the system is provided for
- evaluating if the received biometric data set is within a reference region, wherein the reference regions represent regions associated with the reference biometric data sets of the users;
- evaluating if the received biometric data set is within a blackout region, wherein the blackout regions represent regions associated with the previously received and positively authenticated blackout biometric data sets of the users;
- issuing a positive authentication if the received biometric data set is within one of the reference regions, but outside the corresponding blackout region.
A system for authentication by means of biometric data, the system comprising:
- a biometric data receiver for receiving a biometric data set from a user;
- an electronic token reader for reading from an electronic token a reference biometric data set and at least one blackout biometric data set of a previous and positively authenticated authentication attempt of the respective user;
- wherein the system is provided for
- evaluating if the received biometric data set is within a reference region, wherein the reference region represents a region associated with the reference biometric data set;
- evaluating if the received biometric data set is within a blackout region, wherein the blackout region represents a region associated with the blackout biometric data set;
- and
- issuing a positive authentication if the received biometric data set is within the reference region, but outside the blackout region.
An electronic token with biometric authentication function, comprising a memory for storing a reference biometric data set and for at least one blackout biometric data set of a previous authentication attempt that was positively authenticated.
An electronic token with biometric authentication function, comprising a memory for storing a reference biometric data set and for at least one blackout biometric data set of a previous authentication attempt that was positively authenticated, the electronic token comprising:
- an interface for receiving a biometric data set for authentication;
- a central processing unit for
- evaluating if the received biometric data set is within a reference region, wherein the reference region represents a region associated with the reference biometric data set;
- evaluating if the received biometric data set is within a blackout region, wherein the blackout region represents a region associated with the blackout biometric data set;
- and
- issuing a positive authentication if the received biometric data set is within the reference region, but outside the blackout region.
