Abstract
A method for capturing biometric data of a human and/or other animal, the method comprising: applying localised compression of biological tissue(s), so as to reduce blood volume in target biological tissue(s), and illuminating the target biological tissue(s); OR illuminating the target biological tissue(s) and applying localised compression of biological tissue(s), so as to reduce blood volume in target biological tissue(s); and detecting and analysing: one or more optical reflectance and/or transmission characteristics of the blood volume reduced target biological tissue(s); and/or one or more spectroscopy characteristics of the blood volume reduced target biological tissue(s).

A method for capturing biometric data of a human and/or other animal, the method comprising:
- (a) either (i) applying localized compression of biological tissue(s), so as to reduce blood volume in target biological tissue(s), and illuminating the target biological tissue(s);
- or (ii) illuminating the target biological tissue(s) and applying localized compression of biological tissue(s), so as to reduce blood volume in target biological tissue(s);
- and
- (b) detecting and analyzing:
- (i) one or more optical reflectance and/or transmission characteristics of the blood volume reduced target biological tissue(s);
- and/or
- (ii) one or more spectroscopy characteristics of the blood volume reduced target biological tissue(s).
An apparatus for capturing biometric data of a human and/or other animal, the apparatus comprising:
- a compression device for applying localized compression to biological tissue(s) of the human and/or other animal, so as to reduce blood volume in illuminated target biological tissue(s);
- a detector for detecting (i) optical reflectance and/or transmission characteristics of the blood volume reduced, illuminated target biological tissue(s), and/or (ii) spectroscopy characteristics of the blood volume reduced, illuminated target biological tissue(s);
- and
- a processor for analyzing biometric data of the detector.
A method for capturing biometric data of a human and/or other animal with an apparatus, the apparatus including (a) a compression device for applying localized compression to biological tissue(s) of the human and/or other animal, so as to reduce blood volume in illuminated target biological tissue(s);
- (b) a detector for detecting (i) optical reflectance and/or transmission characteristics of the blood volume reduced, illuminated target biological tissue(s), and/or (ii) spectroscopy characteristics of the blood volume reduced, illuminated target biological tissue(s);
- and (c) a processor for analyzing biometric data of the detector, the method comprising:
- (1) either (i) utilizing the compression device to apply localized compression to biological tissue(s) and reduce blood volume in target biological tissue(s), and illuminating the target biological tissue(s);
- or (ii) illuminating the target biological tissue(s), and utilizing the compression device to apply localized compression to the biological tissue(s) and reduce blood volume in target biological tissue(s);
- (2) utilizing the detector to detect:
- (i) optical reflectance and/or transmission characteristics of the blood volume reduced target biological tissue(s);
- and/or (ii) spectroscopy characteristics of the blood volume reduced target biological tissue(s);
- and
- (3) utilizing the processor to analyze biometric data received from the detector.
