  • the method for authenticating a commercial transaction of the present invention comprises a customer approaching a point-of-sale terminal with goods to be purchased, the customer generating an electronic signature as an expression of intent to commit to the commercial transaction, capturing a digital signature of the customer when the electronic signature is being generated, comparing the captured digital signature of the customer against a reference digital signature, and approving the transaction whenever a predetermined threshold for the authentication has been met and the customer has sufficient funds to cover the transaction.
  • This identity authentication system is used in commercial transactions at a point-of-sale terminal.

  • the customer record already exists.
  • One primary advantage of having the reference data in the customer record is that the amount of memory available reference signature store is not a primary concern. When the reference signature data is to be stored within the transponder, the amount of memory within the transponder may not be sufficient to store such data.
  • the customer record is already in existence but a confirmation check is needed to confirm that the customer has authorized access to the account.
  • the method overcomes the inconvenience of having to re-register all existing customers, Existing customers can use a "dynamic registration" during a routine transaction.
  • Digital and electronic signatures are captured during a routine commercial transaction, using the stylus. Thereafter, during a commercial transaction, the sensed print is compared to the reference print as part of the identity verification process whenever the card is submitted through a cardreader. Similarly, if a transponder is used, perhaps to buy gasoline and other items in a convenience store affiliated with the gas station, the stylus captures the digital signature and uses it as a reference print.

  • the point-of-sale terminal indicates that the transaction will be paid through a transponder.
  • An interrogator disposed at the point-of-sale terminal collects data from the transponder. A light advises the customer that the payment has been accepted. Payment is made instantly from the customer's registered account.
  • the interrogator emits a low-frequency transmission, generally via its antenna.
  • the transponder is inactive until it's activated by the interrogator.
  • the transponder passes within range, the transponder is excited, causing the transponder to transmit its data in response to the inquiry.

  • One significant advantage is that since there is minimal information on the transponder device, if the transponder is lost or stolen it is of little use to thieves and hacks. While they can locate the customer's bank and account number (which they can learn from a personal check), they cannot gain access to such funds since the digital and/or electronic signatures don't match.

  • the method for document authentication exploits a temporally variable physical process to generate a reproducible effect that cannot be copied.
  • a document such as a credit card is provided with a spot or stripe that incorporates at least one, and preferably a large plurality of photo refractive crystals arrayed in a random manner.

  • the response of photo refractive crystals to the coherent illumination comprises a time-varying characteristic that is dependent upon the intensity and temporal nature of the illumination itself. Input to the laser illuminator may be varied to elicit differing responses from the photo refractive crystals, and this factor may be very difficult for a counterfeiter to ascertain. Also, for any given illumination intensity or temporal pattern, the image received by the photosensor varies with time. The time at which the photosensor signal is sampled to obtain an identifying image may also be varied, thereby further compounding the difficulty for a counterfeiter to overcome.

Abstract

L'invention concerne un système d'authentification d'identité utilisé dans des transactions commerciales à un terminal de point de vente. Le système comprend un dispositif de capture d'une signature client (tablette de signature ou stylo à puce), un capteur permettant de détecter une propriété biométrique lors de la transaction, un processeur local, un dispositif sans fil porté par le client, un lecteur de dispositif positionné au terminal de point de vente et un ordinateur hôte. Le client s'enregistre et avise le système à propos d'un compte client à utiliser pour le paiement. Le client soumet aussi une signature électronique (script écrit du nom) et une signature numérique, une empreinte digitale, dans un but de référence. Le client se voit alors attribuer un dispositif sans fil, ce dispositif possédant une mémoire. La mémoire peut être une carte d'identification, une carte de crédit, un transpondeur, un code à barres, ou une combinaison de ces mémoires. Un lecteur de dispositif d'identification (tel qu'un lecteur de carte, un interrogateur, un scanner) est disposé au terminal de point de vente, compatible avec le dispositif sans fil. Lorsque le client utilise un stylo afin de soumettre des données écrites, une signature électronique est générée. De la même manière, un capteur dans le stylo détecte les données utilisées pour la production d'un signature numérique. Une impression de référence peut être obtenue au moyen de la mémoire du dispositif sans fil porté par le client. Les signatures électronique et numérique sont alors comparées aux données de référence afin d'authentifier l'identité.
