초록 ▼

A check or other document verification method in which a data encryption algorithm is applied to personal identification number (PIN) and selected other information particular to each document such as check number or amount of check. The resulting derivation is printed on the face of the document at the time the document is originated, in human readable form and possibly in machine readable form. The recipient of the document is issued a proprietary card, preferably an integrated circuit or “smart card”, which contains an identical algorithm to that used when the document was originated. When the document holder presents a check for cashing or otherwise presents a document for verification, the cardholder is first identified with the card by inserting the card in a terminal and manually entering a PIN as is a common practice. Then the person who was given the document for validation, such as a check cashier, enters the selected information from the face of the document, which is processed utilizing the previously entered PIN and the algorithm from the card to derive a number. The number thus derived may be compared to the derivation which was printed on the document, visually or automatically by incorporating the capability within the terminal for reading the derived number from the face of the document. The proposed method thus validates the cardholder as the legitimate holder of the card, the cardholder as the legitimate holder of the document, and the document as having been legitimately produced for the specific cardholder.

대표청구항 ▼

A method in which the holder of a document is identified by a personal identifier represented in numerical form and is issued a dam-beating card, comprising the steps of: recording a personal-identifier-related card derivation number on said data-beating card; applying a data encryption algorithm to said personal identifier and to a further number together to produce a document derivation number; recording said document derivation number on said document, said further number also being recorded on said document; reading said card derivation number from a data-bearing card presented when said document is being negotiated; ascertaining a personal identifier from a bearer of said document; using said personal identifier as ascertained from said bearer, producing a personal-identifier-related card derivation number and comparing the same with said card derivation number read from said data beating card; and applying a data encryption algorithm to said personal identifier as ascertained from said bearer and to said further number together to produce a document derivation number and comparing the same with said document derivation number recorded on said document.
