<p>The system has a trusted data processing system that can be interconnected using an auxiliary tool on the seller's terminal via a second data line to the buyer's terminal and via a third data line to the seller's terminal for further data exchanges to compete the transaction between the seller's and buyer's terminals initiated via a direct connection, e.g. the Internet. The system has at least one seller's data terminal (2), at least one buyer's terminal (3) and a first data line (D1,DD,D2) via which the seller's data terminal and the buyer's data terminal can be connected directly, for a first data exchange to initiate the business. A trusted data processing system (1A) can be interconnected optionally with the aid of an auxiliary tool on the seller's terminal via a second data line (D1,DT1,D3) to the buyer's terminal and via a third data line (D1,DT2,D3) to the seller's terminal for further data exchanges to compete the transaction between the seller's and buyer's terminals. Independent claims are also included for the following: (a) a trusted data processing system for an electronic data processing system; and (b) a method of conducting business over data lines, especially Internet business.</p> |
