Abstract
A method of authenticating the capture of an image of a three-dimensional entity is provided, including the steps of generating a series of images of the entity with the help of an optical sensor, associating each image with information representative of the position of the sensor at the moment at which it generated the image, and determining whether there is consistency between two images of the series by verifying whether there is consistency between an apparent movement of the optical sensor as determined by comparing characteristic points visible in the two images and an estimated real movement of the optical sensor as determined by comparing information representative of three-dimensional positions of the optical sensor at the moments when it generated the two images.
