Identity checking system having card-bearer biometrical features-stored in codified form

Claim 1

A checking system comprising: a chip card for possession by a bearer, the chip card further comprising a chip card memory, the chip card memory having stored therein a small number of very simple codes representing biometrical feature data pertaining to features of the bearer, each feature being attributed a value, the value representing one of a limited number of different morphological possibilities for the feature, the value being further biometrically codified into a code which is an arbitrarily chosen binary representation of the value, the code thereby being one of the small number of very simple codes which is stored in the chip card memory, and the chip card memory storing exactly one code per feature, and a checking station comprising a card reader for reading the small number of very simple codes stored in the chip card memory, a visual comparison device, the visual comparison device being formed of a display for displaying a composite representation of the bearer's schematically drawn morphological features, the displayed composite representation being assembled based upon the small number of very simple codes stored in the chip card memory and read by the card reader, and the visual comparison device enabling a human operator to perform a visual comparison of (1) the displayed composite representation of the bearer's morphological features with (2) the bearer's actual morphological features.

Claim 14

A method of checking the identity of an individual using a chip card, the method comprising the steps of (A) storing identification data in the chip card on a feature-by-feature basis, the storing step including the steps of examining a morphological feature of the individual, setting a value for the morphological feature, the value being one of a limited number of possible values for the morphological feature, wherein the number of different morphological possibilities for each feature is limited to about ten possibilities, biometrically codifying the value into a code, the biometrically codifying step including the step of storing the code in the chip card, the code forming the identification data, and repeating the examining, setting and codifying steps for a small number of morphological features wherein for each feature only one code is stored, and wherein the one code for each feature is limited to about four bits, such that a small number of very simple codes are stored relating to the morphological features of the individual; and (B) checking the identity of the individual, the checking step including the steps of retrieving and decodifying the stored codes, assembling a composite representation of the plurality of schematically drawn morphological features of the individual, the composite representation being assembled on a feature-by-feature basis based upon the small number of very simple codes, displaying the composite representation of the plurality of schematically drawn morphological features of the individual, the composite representation being displayed to a human operator, and visually comparing (1) the composite representation of the plurality of schematically drawn morphological features with (2) the actual morphological features of the individual the visually comparing step being performed by the human operator.

Claim 15

A method of checking the identity of an individual using a chip card, the method comprising the steps of (A) storing identification data in the chip card on a feature-by-feature basis, the storing step including the steps of examining a morphological feature of the individual, setting a value for the morphological feature, the value being one of a limited number of possible values for the morphological feature, wherein the number of different morphological possibilities for each feature is limited to about ten possibilities, biometrically codifying the value into a code, the biometrically codifying step including the step of storing the code in the chip card, the code forming the identification data, and repeating the examining, setting and codifying steps for a small number of morphological features wherein for each feature only one code is stored, and wherein the one code for each feature is limited to about four bits, such that a small number of very simple codes are stored relating to the morphological features of the individual; and (B) checking the identity of the individual, the checking step including the steps of retrieving and decodifying the stored codes, assembling a composite representation of the plurality of schematically drawn morphological features of the individual, the composite representation being assembled on a feature-by-feature basis based upon the small number of very simple codes, displaying the composite representation of the plurality of schematically drawn morphological features of the individual, the composite representation being displayed to a human operator, and visually comparing (1) the composite representation of the plurality of schematically drawn morphological features with (2) the actual morphological features of the individual the visually comparing step being performed by the human operator.
