Definitions

  • the present invention relates to the field of commercialization for business transactions. More particularly, the present invention relates to the problem of securely and efficiently using a telephone calling card as a credit card for business transactions.
  • eCash is a software-based payment system that allows users to make electronic payments from any computer to any other computer over any computer network including the Internet.
  • An eCash purchase requires three participants - a buyer, a seller, and a bank. Initially, the buyer withdraws digital coins, or eCash, from her bank account. The digital coins are in fact messages having strings of digits with each digital string corresponding to a
  • Patent No. 4,949,380 entitled "Returned-Value Blind Signature Systems”.
  • One drawback of this system is that in order to make a purchase both the buyer and the seller must have accounts on the eCash system. This drawback may be particularly chilling in that the impulse to buy an item or service may not survive the time it takes for a consumer to sign up with such a system.
  • Another drawback is that each purchase requires processing by an intermediary, e.g., a bank, before the purchase is deemed completed.
  • MilliCent is another software based payment system primarily designed for content-based Internet commerce.
  • the MilliCent system is based on the use of "scrip".
  • Scrip is a pre-paid electronic coupon that essentially replaces cash for purchases.
  • Scrip is issued by brokers, that act as intermediaries between consumers and vendors, or by vendors. Basically, a consumer, by way of a credit card, for example, buys vendor specific scrip, i.e., that scrip can only be used to purchase content from a particular vendor, either from a broker or vendor, and then uses the scrip to make purchases.
  • the MilliCent system does not require user accounts it also has drawbacks. For one, each user must subscribe and use MilliCent software.
  • scrip is vendor specific thereby limiting the flexibility of the shopping consumer.
  • eCash MilliCent may have a negative impact on the spur of the moment purchase.
  • the low transactional costs associated with systems such as eCash or MilliCent make them particularly attractive for purchasing items or services that cost as little as 10 cents.
  • a consumer using a credit card to make an electronic purchase first requests the purchase from the merchant. The merchant then contacts the institution that issued the consumer's credit card for authorization. If the purchase is authorized, the merchant is eventually given a token which the merchant transfers into its bank account and the consumer is forwarded a bill from the institution.
  • Using a credit card to make an electronic purchase has it own set of problems. First, although encryption is used in credit card transactions to protect information such as credit card numbers, credit card security is poor.
  • Any merchant can take the information given by the user and purchase additional goods from other merchants; even if the fraud is detected, there is little hope of tracing it back to the dishonest merchant.
  • the danger of eavesdropping or snooping by an outsider to the transaction also poses a significant risk. More significant is the risk associated with break-ins at a host where credit card numbers may be stored. Second, and probably more importantly, credit card overheads are typically high ($0.20 + 2% of transaction cost is typical). This makes credit card payment inappropriate for payments under $1.00.
  • Our invention is a method and system that uses a telephone card to make payments as part of an electronic commercial transaction.
  • our system includes an eCard server connected to a public network through which a consumer and a merchant can communicate and transact business.

  • the server authenticates the signature, verifies that the user has sufficient funds for the purchase, and sends a confirmation to the merchant. After receiving confirmation the merchant then informs the user of the successful purchase. The user is later billed for the item on his phone bill, and the invoice is preserved at the eCard server for auditing and to guarantee non-repudiation of the transaction. In accordance with our invention no private information is passed on to the merchant (even the customer name can be hidden). As such, the risk of fraud is reduced.

It should be noted that although we illustratively separate the merchant 105 from the service provider 112 the merchant and service provider might be the same entity. For example, some telephone companies already have their own on-line shopping networks. In general, after service provider 112 connects the user 101 to merchant 105, the user 101 initiates operation of the system by selecting an item or service offered by merchant.

  • Calling cards are issued by all major telephone companies. These cards have proven to be an effective and convenient way for customers to make toll calls when away from home. Typically, the user dials a toll-free number and types his calling card number and a secret code (PIN). The service provider checks the validity of the number and correctness of the PIN and allows the user to place toll calls. Charges for the calls appear on the user's telephone bill. As such, calling cards already provide a secure method of connecting users over the PSTN. Our invention leverages the security already present in the PSTN and enhances this security on computer networks, e.g., Internet, by using cryptographic techniques.

  • the user 101 appends the secret key to the document and computes a cryptographic checksum, using a standard cryptographic hash function such as MD5 or SHA.

  • Private key encryption is also better suited for our invention because here there is no arbitrary person to whom consumers must identify themselves. More importantly, private key encryption is cheaper to implement and takes advantage of the fact that the service provider issues calling cards and serves as the trusted third party. Nonetheless, public key cryptographic techniques may also be used to authenticate the signature of the customer.
  • FIG. 2 shows the process begins when a consumer or customer 101 places a telephone call 202 to a merchant 105 from either the consumer's home, or by using a calling card, or through some other mechanism identifies himself to the PSTN.

Abstract

L'invention concerne un procédé d'utilisation d'une carte téléphonique pour effectuer des transactions commerciales électroniques. Dans un mode de réalisation, un utilisateur initie un appel téléphonique vers un commerçant avec une carte téléphonique fournie par le fournisseur de services. Le fournisseur de services vérifie d'abord l'identité de l'utilisateur grâce à un code PIN (numéro d'identification personnel) (1). Après validation de l'identité de l'utilisateur, l'appel de l'utilisateur au commerçant est établi. L'utilisateur et le commerçant se mettent alors d'accord sur la vente d'une article et une facture est envoyée au fournisseur de services par le commerçant. La facture est approuvée par l'utilisateur et le commerçant est déconnecté de l'appel. Dans un autre mode de réalisation, l'utilisateur est connecté au commerçant via Internet, l'identité de l'utilisateur ayant été validée auparavant par un fournisseur de services Internet. L'utilisateur tire une copie de la facture pour une application se trouvant sur une page Web. L'application joint la signature numérique de l'utilisateur à la facture et l'envoie par la poste au commerçant. Le commerçant présente alors la facture signée à un serveur qui authentifie la signature du client avant d'approuver la vente.
