Abstract
This document describes systems and techniques directed at spatially-configurable localized illumination for biometric authentication systems. In aspects, during biometric authentication, a biometric authentication system having a biometric authentication manager is configured to receive user input at a touch-sensitive display. Responsive to and based on the user input, the biometric authentication manager determines a shape of a contact area of the user input at the touch-sensitive display. Based on the determined shape, the biometric authentication manager alters a brightness of a region of the display to increase a reflection of light from the user input, effective to facilitate biometric authentication.
