Patent ID: 8855380

Claim:
A device ( 100 ) for identifying or authenticating a person by means of his print, the identification or authentication device ( 100 ) comprising: bearing means ( 102 , 130 ) comprising a transparent base ( 130 ), a rigid frame ( 128 ) secured to the base ( 130 ) and consisting of lateral walls issued from the base ( 130 ) in a direction opposite to a means ( 106 , 126 ) of capturing and forming with the base ( 130 ) a receptacle which is closed except at a face of the receptacle opposite to the base ( 130 ), and a transparent block ( 102 ) supported by said base ( 130 ), filling said receptacle, constrained in the receptacle and on which a part of a body carrying the print is pressed through said face, a surface of the transparent block ( 102 ) on which the part of the body carrying the print is pressed having a test chart ( 132 ), the transparent block ( 102 ) consisting of a flexible material that deforms and fits the shape of the part of the body carrying the print when the latter is pressed thereon, the means ( 106 , 126 ) of capturing an image of said print and of the test chart ( 132 ) through said bearing means ( 102 , 130 ), means ( 108 ) of analyzing the image of the deformed test chart ( 132 ), means ( 110 ) of constructing a template of the print using the image of the test chart ( 132 ) thus analyzed, characterized in that the means ( 110 ) of constructing the template of the print comprise means of calculating a geometric transformation of the deformed test chart ( 132 ) into a non-deformed test chart ( 132 ), geometric transformation means provided for applying said geometric transformation thus calculated to the captured image of the print, and means of generating a template from the thus transformed image of the print, and means ( 114 ) of verifying the identity of the person or means ( 114 ) for authenticating the person from the template thus constructed.
