Abstract
Introduced here are approaches to authenticating unknown persons based on variations in the spatial properties and directionality of blood flow through vessels over time. At a high level, these approaches rely on monitoring vascular dynamics to recognize unknown persons. For example, an authentication platform may examine digital images of an anatomical region to establish how a property of the vasculature within the anatomical region changed as a result of deformation. Examples of properties include the position, size, volume, and pressure of vessels included in the vasculature, as well as the velocity and acceleration of blood flowing through the vasculature.
Claims8
A method for producing a machine learning model that is able to predict blood flow through vasculature of an anatomical region, the method comprising:
- receiving input that is indicative of a request to produce the machine learning model;
- and
- in response to said receiving,
- obtaining
- (i) a first vascular pattern that provides spatial information regarding one or more vessels in the anatomical region while the anatomical region is in an undeformed state,
- (ii) a second vascular pattern that provides spatial information regarding the one or more vessels while the anatomical region is in a deformed state,
- (iii) a first flow pattern that indicates, for the first vascular pattern, how blood flows through the one or more vessels when the anatomical region is in the undeformed state, and
- (iv) a second flow pattern that indicates, for the second vascular pattern, how blood flows through the one or more vessels when the anatomical region is in the deformed state;
- providing the first vascular pattern, the second vascular pattern, the first flow pattern, and the second flow pattern to a machine learning algorithm that produces, as output, the machine learning model;
- and
- storing the machine learning model in a database.
