1. A method of identifying a person by fingerprint/toeprint recognition, consisting in: producing a digital photograph (at 11 ) giving a digitized image ( 13 ) of a fingerprint/toeprint or part of a fingerprint/toeprint (E) present on a surface ( 3 ) of an object ( 12 ); analyzing ( 15 ) said digitized image of the fingerprint/toeprint; detecting characteristic points therein; exchanging ( 16 ) the digital data of the detected characteristic points with a data bank ( 17 ) storing digital data of the characteristic points of a multiplicity of fingerprints/toeprints in its memory, said stored digital data corresponding to plane images of the multiplicity of fingerprints/toeprints; comparing ( 18 ) the digital data of the abovementioned detected characteristic points with the digital data stored in the memory of the data bank; and identifying a person possessing said fingerprint/toeprint as a result of the above comparison, characterized, when the fingerprint/toeprint (E) is on a curved surface ( 3 ), a pre-established model of a curved semicylindrical or semiconical surface of revolution having a shape corresponding or close to the shape of the curved surface or of a portion of the curved surface, to which the fingerprint/toeprint is fixed, is selected, information about the respective positions of the two diametrically opposed generatrices visible in the digitized image is sent to algorithm below a predetermined threshold, by projecting it onto a plane using said algorithm processing means, said corrected image showing the characteristic points of said fingerprint/toeprint in a plane, whereby said plane corrected image is used for detecting the characteristic points of the fingerprint/toeprint and for identifying the person.
