Abstract
Disclosed herein is a field of biometric authentication, in particular the field of anti-spoofing. Further disclosed herein are methods, apparatuses, devices, material information and computer elements for generating biometric authentication information.
Claims31
A device for generating biometric authentication information, the device with instructions, which when executed on one or more processor(s), are configured to carry out the steps:
- providing one or more pattern light image(s), wherein the pattern light image comprises an image of the user under illumination with at least one infrared pattern illuminator of the device;
- generating one or more material properties from the one or more pattern light image(s);
- and
- generating biometric authentication information by providing the generated one or more material properties to at least one layer of a neural network.
1 more element
(canceled)
A method for generating biometric authentication information, the method comprising:
- providing one or more pattern light image(s), wherein the pattern light image comprises an image of the user under illumination with at least one infrared pattern illuminator of the device;
- generating one or more material properties from the one or more pattern light image(s);
- and
- generating biometric authentication information by providing the generated one or more material properties to at least one layer of a neural network.
1 more element
An apparatus for generating biometric authentication information, the apparatus comprising:
- image providing interface configured to provide one or more pattern light image(s), wherein the pattern light image comprises an image of the user under illumination with at least one infrared pattern illuminator of the device;
- a material generator configured to generate one or more material properties from the one or more pattern light image(s);
- and
- a material property provider configured to generate biometric authentication information by providing the generated one or more material properties to at least one layer of a neural network.
