Abstract

A system (10) is provided for enabling biometric identification. The system (10) comprises at least two electrodes (12), a database (14) and a processor (13). The at least two electrodes (12) are to be applied to a face of a subject for capturing electrophysiological signals (51, 52, 53, 54) therefrom. The subject is one of the registered users. The database (14) comprises characteristic eye blink data of registered users. The processor (13) is operably coupled to the electrodes (12) and the database (14) and is operative to receive the electrophysiological signals (51, 52, 53, 54) from the at least two electrodes (12) during at least one eye blink of the subject, to derive eye blink characteristics from the obtained electrophysiological signals (51, 52, 53 54), to make a comparison of the derived eye blink characteristics with at least part of the characteristic eye blink data in the database (14) and to determine an identity of the subject, based on the comparison.

Claims

1. A system (10) for biometric identification, the system (10) comprising:

at least two electrodes (12) for being applied to a face of a subject for capturing electrophysiological signals (51, 52, 53, 54) therefrom,

a database (14) comprising characteristic eye blink data of registered users,

a processor (13) operably coupled to the electrodes (12) and the database (14), the processor (13) being operative to;

receive the electrophysiological signals (51, 52, 53, 54) from the at least two electrodes (12) during at least one eye blink of the subject, the subject being one of the registered users,

derive eye blink characteristics from the obtained electrophysiological signals (51, 52, 53 54),

make a comparison of the derived eye blink characteristics with at least part of the characteristic eye blink data in the database (14),

based on the comparison, determine an identity of the subject.

2. A system (10) for biometric identification as claimed in claim 1, wherein the comparison comprises a morphological comparison.

3. A system (10) for biometric identification as claimed in claim 1, wherein the at least two electrodes (12) are comprised in one measurement device (21, 31).

4. A system (10) for biometric identification as claimed in claim 3, wherein the measurement device is a headgear (31).

5. A system (10) for biometric identification as claimed in claim 4, wherein the headgear (31) is a pair of glasses or a headband.

6. A system (10) for biometric identification as claimed in claim 3, wherein the measurement device (21, 31) further comprises a transmitter (22) for sending the captured electrophysiological signals (51, 52, 53, 54) to a receiver (24), the receiver (24) being coupled to the processor (13).

7. A device (25) for performing biometric identification, the device (25) comprising a processor (13), the processor being operative to:

receive electrophysiological signals (51, 52, 53, 54) from at least two electrodes (12) being applied to a face of a subject during at least one eye blink of the subject,

derive eye blink characteristics from the obtained electrophysiological signals (51, 52, 53 54),

make a comparison of the derived eye blink characteristics with characteristic eye blink data in a database (14) comprising eye blink data of registered users,

based on the comparison, determine an identity of the subject.

8. A method for biometric identification, the method comprising the steps of:

receiving (72) electrophysiological signals (51, 52, 53, 54) from at least two electrodes (12) being applied to a face of a subject during at least one eye blink of the subject,

deriving (73) eye blink characteristics from the obtained electrophysiological signals (51, 52, 53, 54),

making (74) a comparison of the derived eye blink characteristics with characteristic eye blink data of registered users, the subject being one of the registered users, and

based on the comparison, determining (75) an identity of the subject.

9. A computer program product, which program is operative to cause a processor to perform a method as claimed in claim 8.
