METHOD AND DIGITAL COMMUNICATION INFRASTRUCTURE SECURED AND CONTROLLED IN AN ASYNCHRONOUS MODE

摘要

The aim of the invention is to compensate for lack of continuity defects while enabling an industrially satisfactory interfacing using a method that is more secure and enables a better control of the subsequent processing than those currently known. For this purpose, the invention provides an infrastructure for asynchronous data communication between information systems with at least one server via a computer network, including: data extraction means (1) constituting a message to be transmitted from the origin information system; means (2) for time-stamping said message by means of an electronic signature of at least one intervener; encryption means (3); means (4) for encoding the result into an optical symbol; means for displaying and/or printing the symbol (5) on a sustainable medium; means for capturing the symbol by means for optical reading (6) and for symbol recognition (7); means for propagating the recognised data (8) in the computer network to one or more servers supplying the destination information systems; means for processing the message (10) in order to execute planned operations; and means for storing both the message and the processing results for traceability purposes (11).
