Abstract
A method, an apparatus, and a computer program product for biometric verification are disclosed. The method comprises: obtaining a first biosignal indicative of a heart rate of a subject, wherein the first biosignal has been measured by a first sensor; obtaining a second biosignal indicative of the heart rate of the subject, wherein the second biosignal has been measured by a second sensor that is different from the first sensor, and wherein the first and second biosignals have been measured at the same time; determining a delay between the first and second biosignals; and verifying liveness of the subject based on the determined delay.
Claims24
A method for biometric verification, the method comprising:
- Obtaining a first biosignal indicative of a heart rate of a subject, wherein the first biosignal has been measured by a first sensor;
- Obtaining a second biosignal indicative of the heart rate of the subject, wherein the second biosignal has been measured by a second sensor that is different from the first sensor, and wherein the first and second biosignals have been measured at the same time;
- determining a delay between the first and second biosignals;
- and
- verifying liveness of the subject based on the determined delay.

An apparatus comprising at least one processor, at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform:
- obtaining a first biosignal indicative of a heart rate of a subject, wherein the first biosignal has been measured by a first sensor;
- obtaining a second biosignal indicative of the heart rate of the subject, wherein the second biosignal has been measured by a second sensor that is different from the first sensor, and wherein the first and second biosignals have been measured at the same time;
- determining a delay between the first and second biosignals;
- and
- verifying liveness of the subject based on the determined delay
23-25. (canceled)
A non-transitory computer-readable medium comprising computer program code configured to, when executed by at least one processor, cause an apparatus to perform:
- obtaining a first biosignal indicative of a heart rate of a subject, wherein the first biosignal has been measured by a first sensor;
- obtaining a second biosignal indicative of the heart rate of the subject, wherein the second biosignal has been measured by a second sensor that is different from the first sensor, and wherein the first and second biosignals have been measured at the same time;
- determining a delay between the first and second biosignals;
- and
- verifying liveness of the subject based on the determined delay.
