A complete system for the purchasing of goods or information over a computer network is presented. Merchant computers on the network maintain databases of digital advertisements that are accessed by buyer computers. In response to user inquiries, buyer computers retrieve and display digital advertisements from merchant computers. A digital advertisement can further include a program that is interpreted by a buyer's computer. The buyer computers include a means for a user to purchase the product described by a digital advertisement. If a user has not specified a means of payment at the time of purchase, it can be requested after a purchase transaction is initiated. A network payment system performs payment order authorization in a network with untrusted switching, transmission, and host components. Payment orders are backed by accounts in an external financial system network, and the payment system obtains account authorizations from this external network in real-time. Payment orders are signed with authenticators that can be based on any combination of a secret function of the payment order parameters, a single-use transaction identifier, or a specified network address.

[ What is claimed is:] [1.] An open network sales system providing for real-time authorization of purchase transactions, comprising:a plurality of buyer computers; anda plurality of merchant computers;said plurality of buyer computers and said plurality of merchant computers being interconnected by a public packet switched communications network;at least one of said plurality of merchant computers being programmed to store digital advertisements in a database;each one of said buyer computers being programmed to receive a user inquiry and, in response to said user inquiry, to select at least one of said merchant computers and to transmit a network request thereto over said public packet switched communications network;at least one of said merchant computers being programmed to cause one of said digital advertisements to be communicated to said one of said buyer computers over said public packet switched communications network in response to said network request from said buyer computer;said one of said buyer computers being programmed to display said one of said digital advertisements, and, in response to a user request, to transmit over said public packet switched communications network to at least one of said merchant computers a purchase message and to cause a payment request, comprising a payment amount, to be transmitted over said public packet switched communications network into a payment system comprising a financial authorization network external to said public packet switched communications network, in order to initiate authorization of purchase of a product having real monetary value advertised in said one of said digital advertisements and in order to initiate recordation of information pertaining to said payment request and an authorization in a settlement database;at least one of said merchant computers being programmed to receive said purchase message, and to cause said product to be sent to a party conditioned on said purchase transaction having been authorized in real time by said financial authorization network external to said public packet switched communications network, based on an external credit card account or an external demand deposit account having sufficient credit or funds of real monetary value available to a principal making said payment, and conditioned on at least one message transmitted over said public packet switched communications network in connection with purchase of said product not being a replay attack of a message previously transmitted over said public packet switched communications network;said payment request comprising at least one digital signature of components that include components derived from said payment request, at least one of which digital signatures protects said payment request from forgery, including authenticating an identity of one of a plurality of principals as an originator of said payment request, at least one of which digital signatures protects said payment request from replay attack, and at least one of which digital signatures is computed based on a principal-specific secret key.
