Abstract
Method for Checking the Integrity of a User Authentication Video for an Electronic Device. The present invention relates to a method for checking the integrity of a user authentication video for an electronic device (10), comprising: the random generation of a zoom control function, the acquisition, by a camera (14), of a video of the user's face, while automatically controlling the zoom according to the zoom control function, the detection of the user's face on the acquired video, the determination of a reconstructed zoom control function based on the evolution of the surface of the face detected on the video, and the correlation of the zoom control function with the reconstructed zoom control function so as to obtain a classification result indicating whether or not the video can be considered intact with the user physically present in front of the camera (14).
