Abstract
Disclosed herein is a method for authenticating a user of a device. The method includes: a. projecting a plurality of light beams through a display onto the user by a projector, where the plurality of light beams includes a first light beam and a second light beam, and directing the first light beam and the second light beam to illuminate an at least partially overlapping area of the user by the display, b. generating a pattern image showing the projecting of the plurality of light beams onto the user, c. extracting liveness data from the pattern image, d. allowing the user to perform an operation on the device that requires authentication based on the liveness data.
Claims20
A method for authenticating a user of a device, the method comprising:
- a. projecting a plurality of light beams through a display onto the user by a projector, wherein the plurality of light beams comprises a first light beam and a second light beam, and directing the first light beam and the second light beam to illuminate an at least partially overlapping area of the user by the display,
- b. generating a pattern image showing the projecting of the plurality of light beams onto the user,
- c. extracting liveness data from the pattern image, and
- d. allowing the user to perform an operation on the device that requires authentication based on the liveness data.
A device for authenticating a user, the device comprising:
- at least one projector configured for projecting the plurality of light beams through at least one display onto the user, wherein the plurality of light beams comprises a first light beam and a second light beam, and directing the first light beam and the second light beam to illuminate an at least partially overlapping area of the user by the display,
- at least one image generation unit configured for generating a pattern image showing the projecting of the plurality of light beams onto the user, and
- at least one processor configured for extracting liveness data from the pattern image and allowing the user to perform an operation on the device that requires authentication based on the liveness data.
