A biometric is a substantially stable physical or behavioral characteristics of a person which can be automatically measured and characterized for comparison. In accordance with the subject invention an identification card includes an encrypted representation of the biometric characteristic, which may be a finger print or a description of the manner in which the person signs his or her name, including the order and velocity in which strokes comprising a signature are written. The identification card is validated, and the person identified by an apparatus including a scanner which simultaneously scans two fields. The card is position in the first field and the biometric (e.g. a thumbprint) is simultaneously positioned in the second field and both are scanned at once, to produce a composite signal including both the code of representation and the scanned biometric. A microprocessor separates the composite signal, decodes the coded representation, and compares it to the stand biometric to validate the card. By simultaneously scanning both the coded representation and the biometric with a single scanner the cost of the apparatus is reduced as is the opportunity for a breach of security.

An apparatus for verifying an identification card and the identity of a person to be identified by said card, said card including scannable indicia representative of an encryption of a biometric derived from a selected metric of said person to be identified, said apparatus comprising: a) a scamper for scanning a field, said field comprising first and second sub-fields; b) first means for positioning said card so that said indicia lie within said first sub-field; c) second means for positioning a correspondingly selected biometric characteristic of a person presenting said card within said second sub-field; and d) data processing means for: d1) controlling said scanner to scan said field when said indicia and said correspondingly selected biometric are positioned within said first and second sub-fields respectively, d2) receiving a data image of said indicia and said correspondingly selected biometric from said scanner; d3) partitioning said data image into first and second sub-images corresponding to said first and second sub-fields respectively; d4) recovering said encryption from said first sub-image; d5) decrypting said encryption to recover said metric and verify said card; d6) comparing said second sub-image to said metric; mad d7) if said comparison is successful, outputting a sigmal indicating that said person presenting said card is said person to be identified by said card.
