  • the user When ordering a service of interest, the user now typically sends the to the supplier, together with confidential bank information, such as the credit card number, to the supplier, in order in this way to initiate a cashless payment for the desired services. It is also possible that the customer has a current account with the supplier, from which a charge is made when a service is ordered, specifying a secret number relating to the account.
  • the present invention is therefore based on the object of providing a method for requesting data from a bidder computer by a customer computer and for delivering the data over a network to the customer computer after approval by a test center, in which an undesired access is provided Stranger to the data supplied is excluded.
  • this object is achieved by a method for requesting data from a bidder computer by a customer computer and for delivering the data over a network to the customer computer after approval by a customer computer Test center, with the following steps:
  • connection-oriented network Establishing a connection between the test center and the customer computer via a connection-oriented network and a connection between the test center and the bidder computer via a connection-oriented network
  • this object is achieved by a method for requesting data from a bidder computer by a customer computer and for delivering the data over a network to the customer computer after approval by a test center, with the following steps:
  • a customer requests certain data from a bidder computer by means of his personal computer or customer computer which is connected to the Internet.
  • the data can be programs, multimedia data, texts, images, pieces of music stored in data form and the like.
  • the customer computer transmits to the bidder computer his name and / or his ISDN telephone number, a description of the desired data and a reference to his bank, which also functions as a clearing bank or clearing house or Internet bank can be designed.
  • this data transmission takes place via the Internet.
  • Other, non-connection-oriented data networks can be considered for this connection, as can transmission via a connection-oriented data network, such as the ISDN network.
  • the bidder computer After receipt of this request, the bidder computer establishes a connection to the bank computer via a connection-oriented network, which in the exemplary embodiment considered here is preferably the ISDN network.
  • a connection-oriented network which in the exemplary embodiment considered here is preferably the ISDN network.
  • the bidder computer transmits its number to the bank computer in the signaling channel, which, by comparing the number with a list of ISDN numbers from bidders with whom the bank computer works, determines whether the owner of the bidder computer is with the bank partners heard. If this is not the case, the bank computer terminates the connection. Otherwise a connection is established.
  • the bidder computer transmits the customer name, its ISDN number and the amount of money due for the requested data to the bank computer.
  • the bank computer then checks whether the customer name and the customer telephone number are contained in a list of bank customer names and their telephone numbers and are stored there in accordance. If this is not the case, the bank computer gives the bidder computer the non-approval for the data delivery to the customer computer. The bank computer also notifies the bidder computer of the non-approval if the requested amount of money is not covered by the customer's account. Otherwise, the bank computer communicates an encryption key to the bidder computer. Since the encryption key is transmitted to the bidder computer via the connection-oriented network, the encryption key cannot be misdirected. Furthermore, the bank computer establishes a connection to the customer computer via a connection-oriented network, preferably the ISDN network, and transmits a decryption key that matches the encryption key to the customer computer. Here too, misdirection is impossible due to the connection-oriented network over which the decryption key is transmitted.
  • a connection-oriented network preferably the ISDN network
  • the bidder computer now encrypts the data requested by the customer computer using the key received from the bank computer and transmits the encrypted data to the customer computer via the Internet or another network which is not necessarily protected from third-party access. As soon as the customer computer has received all the data, it acknowledges receipt of the data and transmits a corresponding confirmation to the bidder computer.

  • a second exemplary embodiment of the method according to the invention corresponds to the first exemplary embodiment described above with regard to the following initial steps: establishing the Internet connection between the customer computer and the bidder computer; Requesting the data by the customer computer from the bidder computer; Establishing the ISDN connection between the bidder computer and the bank computer; Transmission of the request relating to the customer from the bidder computer to the bank computer and checking by the bank computer whether the customer computer fulfills the requirements for the delivery of data by the bidder computer, namely whether the customer name and its ISDN telephone number are included in the customer list at the bank computer and whether the amount of money due for the data requested by the customer computer is covered by the customer account. If this customer requirement for the delivery of data is not met, the corresponding non-approval is also communicated to the bidder computer again. Otherwise, the method continues in the following manner, modified from the first exemplary embodiment:
  • the bank computer transmits the encryption key to the bidder computer via the ISDN network, which then encrypts the data requested by the customer computer and transmits the encrypted data to the customer computer via the Internet.
  • the customer computer After complete receipt of the encrypted, requested data, the customer computer establishes a connection via the ISDN network to the bank computer and transmits to the bank computer a confirmation of receipt of the requested data, which then attaches a key for decrypting the data via the ISDN network retransmits the customer computer, which matches the encryption key previously sent to the bidder computer.
  • the customer computer now decrypts the received, encrypted data using the decryption key.
  • the customer's account is debited from the bank computer in the amount of the amount due.

  • the method can be transferred to any type of test center that checks the customer's authorization to receive the data offered by the bidder computer and, if authorized, transmits an encryption key to the bidder computer on the one hand via a connection-oriented network and on the other hand to the bidder computer via a connection-oriented network
  • Customer computer transmits a decryption key, which ensures that the encrypted data transmitted by the bidder computer over a non-secure network, such as the Internet, can only be decrypted by the authorized customer.
  • the encryption key and the decryption key will only be used for the one data transfer requested by the customer computer, so that future transfers of data are associated with different encryption key / decryption key combinations.
  • the data telegrams to be exchanged by the inspection body which can be the bank computer in the example, on the one hand with the bidder computer and on the other hand with the customer computer are very short and typically have a content of less than 131 bytes. Therefore, a maximum of a single unit is incurred for each ISDN connection, so that the costs for handling the checked data request and delivery method according to the invention remain low.
  • the inspection body can also be designed as a clearing house for credit card information.
  • the customer computer also transmits to the bidder computer the credit card information, which the bidder computer transmits to the clearing house together with the request relating to the customer, which, by means of an additional connection, asks the authorization from the credit card organization for the amount charged on a customer account and if the credit card organization is approved, the bidder computer provides the key for the encryption of the data desired by the customer computer and the decryption key for the customer computer.

Abstract

L'invention concerne un procédé de livraison de données par un ordinateur prestataire à un ordinateur client sur demande de ce dernier, livraison qui n'a lieu que si une autorisation est délivrée par un poste de contrôle. Une fois que l'ordinateur client a demandé les données désirées à l'ordinateur prestataire, ce dernier transmet une demande d'information concernant le client au poste de contrôle qui vérifie si ce client satisfait à des conditions requises précises. Si c'est le cas, une connexion est établie via un réseau orienté connexion d'une part entre le poste de contrôle et l'ordinateur client et d'autre part entre le poste de contrôle et l'ordinateur prestataire, des clés étant transmises du poste de contrôle à l'ordinateur prestataire et à l'ordinateur client grâce auxquelles l'ordinateur prestataire code les données qui sont transmises sous forme codée à l'ordinateur client qui les décode alors.
