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.
