Abstract
Disclosed is a checking device that is intended to check the authenticity of a fingerprint of a finger and which includes, among other things, a capture system for capturing an image of the finger and of the fingerprint, and acquisition means for acquiring a three-dimensional model of the finger. The checking device also includes means for determining the core on the image of the fingerprint, for locating the crown of the three-dimensional model, for determining the orientation and position of the end of the finger and for determining the relative positions of the end, the crown and the core. From these elements, the checking device can decide whether the fingerprint is real or false.
