SPOOFING DETECTION DEVICE, SPOOFING DETECTION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18212513 titled 'SPOOFING DETECTION DEVICE, SPOOFING DETECTION METHOD, AND RECORDING MEDIUM

Simplified Explanation

This patent application is about a technology that can accurately detect spoofing in face authentication without adding complexity to the device or burdening the user. Here are the key points:

  • The technology includes a device with various components to detect spoofing in face authentication.
  • The facial image sequence acquisition unit captures a sequence of images showing the user's face.
  • The line-of-sight change detection unit analyzes the temporal changes in the user's line-of-sight from the facial image sequence.
  • The presentation information display unit shows information to the user during the authentication process.
  • The spoofing determination unit uses the line-of-sight change information to determine the likelihood of the face in the image sequence being a spoof.
  • The technology aims to improve the accuracy of detecting spoofing without requiring significant changes to the device or adding extra burden on the user.


Original Abstract Submitted

To provide a technology of more accurately detecting spoofing in face authentication, without increasing a scale of a device configuration and a burden on a user. A spoofing detection device includes a facial image sequence acquisition unit, a line-of-sight change detection unit, a presentation information display unit, and a spoofing determination unit. The facial image sequence acquisition unit acquires a facial image sequence indicating the face of a user. The line-of-sight change detection unit detects information about a temporal change in the line-of-sight from the facial image sequence. The presentation information display unit displays presentation information presented to the user as part of an authentication process. The spoofing determination unit determines the likelihood of the face indicated by the facial image sequence being spoofing on the basis of the information about the temporal change in the line-of-sight with respect to the presentation information.
