Definitions

  • This invention relates to an apparatus and method for verifying transactions conducted over an electronic communication link to determine that the individual conducting the transaction is authorized.
  • a great many transactions are now conducted over the telephone or other electronic communication link. For example, it is common practice to make purchases over a telephone using a credit card. The individual conducting the transaction identifies him or herself and gives the person taking the order the credit card number. The individual placing the order, however, may not be authorized and the transaction may be fraudulent. Nevertheless, it is very desirable to conduct transactions of many different types by telephone, provided there is a reliable way to verify that the person conducting the transaction is authorized. For example, consumers could pay bills electronically over a telephonic communication network, thus avoiding the time and costs associated with writing cheques and waiting for mail delivery. This would also eliminate costs incurred by producers and banking institutions. Such costs include those associated with the depositing and clearing of cheques, including the cost of microfilming and returning cancelled cheques to consumers.
  • a further benefit is instant verification of the availability of funds to cover the transaction, thus saving the expense of resubmitting for payment of a cheque that was rejected for insufficient funds.
  • various establishments have began offering consumers the option of having their bill automatically paid via automatic funds transfer. This has been proven to be useful for paying bills that are for the same monthly amount, but has been found to be undesirable for bills that vary based upon customer usage, or from period to period due to the consumer not being aware of the billing amount prior to the automatic payment thereof. In these situations, the consumer has no opportunity to review and approve the charges prior to the payment being made.
  • These bill payment options are generally restrictive in that the consumer typically has no flexibility to pay the bill on a date other than that pre-specified at the time the automatic funds transfer is established.
  • the transaction verification apparatus and method of this invention has several features, no single one of which is solely responsible for its desirable attributes. Without limiting the scope of this invention as expressed by the claims which follow, its more prominent features will now be discussed briefly. After considering this discussion, and particularly after reading the section entitled, "DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS," one will understand how the features of this invention provide its benefits, which include preventing unauthorized use of credit information and personal and confidential information, convenience and simplicity in conducting transactions involving transfer of sensitive or confidential data via conventional telephone equipment or other communications links such as computers and point of sale devices.
  • the first feature of this invention is that the transaction is conducted over an electronic communication link, including, but not limited to, telephone networks, both wire and wireless, cordless, digital or voice, carried by means of wire, fiber optics, radio link, network, satellite, optical link, inductive transfer, encoded or modulated.
  • the second feature is that it encompasses a variety of transactional situations, especially situations that require proof of identity when dealing with banks, governmental agencies, and other institutions.
  • it may involve paying bills, transferring of funds between accounts, purchasing by phone, off-site wagering, arming and disarming security systems, 900 telephone number user verification, bulletin board access, voting electronically with voter verification, and verifying house arrest, stock trading, telephone and on-line computer usage and software exchanging, purchasing a gun, or obtaining a license, calling card verification, and deployment.

  • a plurality of fingerprint images may be used to form a fingerprint code by arranging the fingerprints in a predetermined sequence. Thus, the authorized person conducting the transaction will enter his or her fingerprints in this sequence. Otherwise the transaction will not be authorized.
  • the fourth feature is a fingerprint reader which scans a finger/fingers of the person conducting the transaction to form electronic data signals corresponding to an image of the fingerprint or fingerprints of this finger or fingers.
  • the fingerprint reader is employed with any instrument that can interface with the electronic communications link. Examples of such instruments are telephone devices, including radio and cellular telephones, modems, computers and peripherals, point of sale devices, like cash registers, gas pumps and credit card authorization reader mechanisms.
  • the telephone instrument includes a credit card reader mechanism that reads data on the credit card off the magnetic strip or microchip.
  • the fingerprint reader includes a platen on which the finger or fingers of the person conducting the transaction is placed, a frame grabber which captures a high resolution image or images of the fingerprint or fingerprints of this finger or fingers, and a digitizer device which converts this image or images into digitized electronic data signals corresponding to the fingerprint or fingerprints of the person conducting the transaction.
  • the fifth feature is a transmitter which transmits to comparator device, either remote or local, the electronic data signals or authorization signals corresponding to the image or images of the fingerprint or fingerprints of the person conducting the transaction.
  • the transaction is only completed if the electronic data signals corresponding to the image or images of the fingerprint or fingerprints of the person conducting the transaction substantially correlate with the stored electronic image or images of the fingerprint or fingerprints of the individual authorized to conduct the transaction.
  • the transmitter is preferably, and not limited to a telephone instrument or computer, and is adapted to transmit and receive voice signals, and to transmit the electronic data signals corresponding to the image or images of the fingerprint or fingerprints of the person conducting the transaction.
  • the sixth feature is that the invention preferably includes an encoder device which is capable of encrypting the electronic data signals corresponding to the image or images of the fingerprint or fingerprints of the person conducting the transaction, or the amount of funds being transferred, or the identification of the authorized person, or authorization signal. There would also be a decoder employed to decrypt the message at the point of authorization.
  • the seventh feature is that the invention preferably includes a thermal test device which determines that the fingerprint reader is scanning a finger or fingers that are scanned one at a time of a living person.
  • the eighth feature is that apparatus is provided for authorizing the payment of bills electronically.
  • the apparatus includes a transaction data input device having a first selector, such as, for example, a keyboard, for selecting a creditor to whom a payment is to be made, a second selector, such as, for example, a keyboard, for selecting a payment source, and a numeric selector, such as, for example, a keyboard, for specifying a payment amount to the creditor.

Abstract

L'invention a pour objet un dispositif de mémorisation dans lequel est mémorisée une image électronique d'une empreinte digitale d'un individu autorisé à effectuer une transaction (34). Un doigt, d'une personne effectuant une transaction, est scanné (18 et 24) pour former des signaux (28) de données électroniques correspondant à une représentation électronique de l'empreinte digitale. L'image électronique mémorisée est comparée (32) aux signaux de données électroniques correspondant à l'empreinte digitale de la personne réalisant la transaction. La transaction n'est autorisée que lorsque les signaux de données électroniques représentant l'empreinte digitale formant image de la personne effectuant la transaction correspondent sensiblement à l'image électronique mémorisée de l'empreinte digitale de l'individu autorisé à réaliser la transaction. Dans un mode de réalisation, les signaux de données électroniques correspondant à l'image de l'empreinte digitale de la personne réalisant la transaction sont transmis par la liaison de communication codée à un comparateur à distance qui compare l'image électronique mémorisée aux signaux de données électroniques correspondant à l'image de l'empreinte digitale de la personne réalisant la transaction.
