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.
An open network sales system providing for real-time authorization of purchase transactions, comprising:
An open network payment system for transferring funds having real monetary value from a sender to a beneficiary and providing for real-time authorization of payment transactions by a financial authorization network external to said network payment system, comprising:
A method of effecting sales over a network sales system comprising a plurality of buyer computers and a plurality of merchant computers interconnected by a public packet switched communications network, said method providing for real-time authorization of purchase transactions and comprising the steps of:
A method of transferring funds having real monetary value from a sender to a beneficiary using a network payment system comprising a plurality of client computers and at least one payment computer interconnected by a public packet switched communications network, said method providing for real-time authorization of purchase transactions by a financial authorization network external to said public packet switched communications network, and comprising the steps of:

An open network payment system for transferring funds having real monetary value from a sender to a beneficiary and providing for real-time authorization of payment transactions by a financial authorization network external to said network payment system, comprising:
A method of transferring funds having real monetary value from a sender to a beneficiary using a network payment system comprising a plurality of client computers and at least one payment computer interconnected by a public packet switched communications network, said method providing for real-time authorization of purchase transactions by a financial authorization network external to said public packet switched communications network, and comprising the steps of:
A payment computer for use in transferring funds having real monetary value from a sender to a beneficiary, said payment computer being programmed to receive, over a public packet switched communications network, a payment request specifying a payment amount to be transferred from said sender to said beneficiary, 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, said payment computer further being programmed to authenticate said payment request, to cause a message to be transmitted into a financial authorization network external to said network payment system, in order to verify that said sender has adequate funds or credit having real monetary value, to receive an authorization from said financial authorization network in response to said message, to transmit an authorization message over said public packet switched communications network, said authorization message comprising an authenticator proving that said payment computer originated said authorization message, to cause information pertaining to said payment request and authorization to be recorded in a settlement database, and to cause funds having real monetary value to be transferred from said sender to said beneficiary conditioned on said payment request 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 said sender, and conditioned on at least one message transmitted over said public packet switched communications network in connection with transfer of said funds not being a replay of a message previously transmitted over said public packet switched communications network.
A payment computer for use in transferring funds having real monetary value from a sender to a beneficiary, said payment computer being programmed to receive, over a public packet switched communications network, a payment request specifying a payment amount to be transferred from said sender to said beneficiary, 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, said payment computer further being programmed to authenticate said payment request, to cause a message to be transmitted into a financial authorization network external to said network payment system, in order to verify that said sender has adequate funds or credit having real monetary value, to receive an authorization from said financial authorization network in response to said message, to transmit an authorization message over said public packet switched communications network, said authorization message comprising an authenticator proving that said payment computer originated said authorization message and being capable of validation without use of a secret key, to cause information pertaining to said payment request and authorization to be recorded in a settlement database, and to cause funds having real monetary value to be transferred from said sender to said beneficiary conditioned on said payment request 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 said sender, and conditioned on at least one message transmitted over said public packet switched communications network in connection with transfer of said funds not being a replay of a message previously transmitted over said public packet switched communications network.
