Abstract
Introduced here are approaches to authenticating unknown persons based on variations in the properties of blood vessels over time. At a high level, these approaches rely on monitoring changes in a property of a blood vessel that occur over time. Examples of properties include the position, size, volume, and pressure of the blood vessel, as well as the velocity and acceleration of blood flowing through the blood vessel.
