Data is transmitted between a client (202) and a server (204), such data can include billing and shipping information. A process (200) performs a request (202) from a client(buyer) to a server(merchant). The server (204) returns an order form to the client (202). If the transaction is the client's first order (206), then the client completes the order form (204) and submits the completed order form to the server (208). The server then performs the action of checking the client's credit (210), and generates a new encryption key pair (210). The server returns the encrypted cookie to the client (212), optionally together with an indentifier that associated the cookie with the client (212). The server retains the key (214), but deletes the encrypted cookie and any non- encrypted information from its database (214). If this is a subsequent order from the client, as determined in step (206), then the server decrypts the received cookie with the encryption key retained by the server, step (222), and then the client completes order form (204), and submits to server (224). The server returns the completed order form to client with new key/cookie (226), and the client verifies the order (228). The process (200) then returns to step (210), then step (212), then step (214), and then terminates with step (216).
L'invention porte sur un système et un procédé de sécurisation de transmission, stockage et extraction de données sur un réseau. Les données contenant, par exemple, des informations sensibles telles que des enregistrements de facturation et d'expédition dans une transaction commerciale, sont cryptées et placées sur un système, la clé de cryptage/décryptage étant placée sur un autre système. Le seul point commun entre les systèmes se limite à l'échange d'informations. Il est difficile de rentrer par effraction dans ce système, car il faut mettre en échec les deux systèmes si l'on veut accéder aux données cryptées.
