US Patent 11157606

• Title: Facial recognition authentication system including path parameters
• Assignee: Facetec Inc.
• Inventors: Kevin Alan Tussy
• Filing Date: 2020-03-12
• Issue Date: 2021-10-26
• Abstract: The patent describes a facial recognition authentication system that uses a user's computing device, which has a camera and, optionally, movement-detecting sensors (like an accelerometer, magnetometer, and gyroscope). Users enroll by providing images of their face taken as they move the device relative to their head. The system records biometric information from these images and the movement path ("enrollment movement"). For authentication, users provide new images while performing a similar movement ("authentication movement"). The system compares the authentication biometrics and movement with the stored enrollment information. Additional security features include feedback displays, rewards for successful use, banding/glare/screen edge detection, analysis of user attributes (gender, age, ethnicity), gradual access, display modifications (e.g., small video feedback, warped edges, white background), infrared imaging, reflection of displayed patterns off eyes, eye tracking, and analysis of perspective distortion. The system can be implemented on the mobile device, a remote server, or both.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a method for a computer-implemented facial recognition authentication. It involves:

  1. Receiving multiple enrollment images of a user's face, captured by a camera on a computing device while the device is moved to different positions relative to the user's head.
  2. Receiving enrollment movement data from the computing device's movement sensors (e.g., accelerometer, magnetometer, gyroscope) that describes the path of the device during the capture of the enrollment images.
  3. Storing this enrollment information (images and movement data) linked to the user.
  4. Later, receiving multiple authentication images of a user's face, captured by a camera on a computing device while the device is moved to different positions relative to the user's head.
  5. Receiving authentication movement data from the computing device's movement sensors that describes the path of the device during the capture of the authentication images.
  6. Comparing the authentication information (images and movement data) with the stored enrollment information.
  7. Authenticating the user if the comparison meets a predetermined correspondence level.
  8. If authentication fails, transmitting an email to an email address associated with the user.

• Claim 11: This claim describes a system for secure authentication of a user. It includes:

  1. A mobile computing device with a camera and movement sensors (e.g., accelerometer, magnetometer, gyroscope).
  2. A server configured to communicate with the mobile device over a network.
  3. The server is designed to:
     • Receive enrollment images and enrollment movement data (from the device's camera and sensors) representing a user's face and the device's movement during image capture.
     • Store this enrollment information linked to the user.
     • Receive authentication images and authentication movement data (from the device's camera and sensors) during a later authentication attempt.
     • Compare the authentication images with the enrollment images, and the authentication movement with the enrollment movement.
     • Authenticate the user if the comparison meets a predefined correspondence level.

• Claim 12: This claim specifies a non-transitory computer-readable medium containing instructions which, when executed by a processor, perform a method comprising:

  1. Receiving multiple enrollment images of a user's face, captured by a camera on a computing device while the device is moved to different positions relative to the user's head.
  2. Receiving enrollment movement data from the computing device's movement sensors (e.g., accelerometer, magnetometer, gyroscope) that describes the path of the device during the capture of the enrollment images.
  3. Storing this enrollment information (images and movement data) linked to the user.
  4. Later, receiving multiple authentication images of a user's face, captured by a camera on a computing device while the device is moved to different positions relative to the user's head.
  5. Receiving authentication movement data from the computing device's movement sensors that describes the path of the device during the capture of the authentication images.
  6. Comparing the authentication information (images and movement data) with the stored enrollment information.
  7. Authenticating the user if the comparison meets a predetermined correspondence level.
