DETECTING SPOOF IMAGES USING PATTERNED LIGHT - A simplified explanation of the abstract

This abstract first appeared for US patent application 17804293 titled 'DETECTING SPOOF IMAGES USING PATTERNED LIGHT

Simplified Explanation

The patent application is about determining whether an imaged subject is real or fake.

• The invention is a computing system that includes a camera and a light pattern source.
• The system captures an image of a subject illuminated by the light pattern.
• It determines whether the subject is real or a spoof based on the contrast of the light pattern in the image.
• If the subject is determined to be real, the system performs an action.
• If the subject is determined to be a spoof, the system does not perform the action.

Original Abstract Submitted

Examples are disclosed herein that relate to determining whether an imaged subject is real or spoofed. One example provides a computing system, comprising, a camera, a light pattern source configured to output a light pattern, a logic subsystem, a storage subsystem storing instructions executable by the logic subsystem to capture, via the camera, an image of a subject illuminated by the light pattern emitted by the light pattern source, determine, based at least upon a contrast of the light pattern in the image, whether the subject is real or a spoof, based at least upon determining that the subject is real, perform an action on the computing system, and based at least up on determining that the subject is a spoof, not perform the action on the computing system.
