Abstract
The invention concerns an identification process that makes it possible to confer traceability to manufactured products (PROD), from data of origin (C, D) initially brought together at a source point (P_SOURCE) and including a control identification number (C) and manufacturing data (D) common to these products (PROD). The process of the invention provides for the formation of two parallel information flows, (Φand Φ), each of which ensures a propagation of the data of origin (C, D) in time and space from the source point (P_SOURCE), and includes three tests (COMPAR, COMPAR, COMPAR) that makes it possible to verify the internal consistency and integrity of these data of origin in the form in which they are propagated.
