Method for identifying a person among a population by sensing his fingerprints

摘要

The invention concerns a method for identifying a person among a population by sensing the fingerprints of at least one finger of his hand and comparing said fingerprints with fingerprint data of all the persons of the population previously stored in a file (1); it consists in sensing in the first place the shape of at least one hand of all the persons and in storing hand shape data in the file (1) in correlation with respective fingerprint data; then during the process identifying a person, in detecting (in 3) the shape of his hand and (in 2) the fingerprints of at least one finger; comparing (5) the data concerning the shape of his hand with the data concerning the hand shapes stored in the file (1) for the whole population; selecting (6) in the file a group consisting of hand shapes substantially identical with the sensed shape of the hand of the person to be identified; and comparing (8) the sensed fingerprints of the person to be identified with the data stored in the file in correlation with respectively the hand shapes of only the persons of the selected group.
