Spoofing detection device, spoofing detection method, and spoofing detection program

摘要

The present invention provides a technique for more accurately detecting impersonation in face authentication without increasing the device configuration and the burden on the user. The impersonation detection device 1 includes a face image sequence acquisition unit 11, a line-of-sight change detection unit 12, a presentation information display unit 13, and an impersonation determination unit 14. The face image sequence acquisition unit 11 acquires a face image sequence representing the user's face. The line-of-sight change detection unit 12 detects information on temporal changes in the line of sight from the face image sequence. The presentation information display unit 13 displays the presentation information presented to the user as part of the authentication process. The impersonation determination unit 14 determines the possibility that the face represented by the face image sequence is impersonated based on the information on the temporal change of the line of sight with respect to the presentation information.
