TRACEABILITY OF A CHAIN OF BLOCKS OF MULTI-ACTORS PROCESSES, ALLOWING AT LEAST TWO LEVELS OF CONFIDENCE TO STOCKEY INFORMATION

摘要

The invention relates to a system for traceability of a chain of processes carried out by several actors (201, 202, 203), comprising a database (100) for storing the information generated for each processing of said chain, and in which each actor can, after obtaining a right of access to said database, add a first piece of information (101, 103) signed by means of a certificate obtained from a secure hardware device (301, 302, 303) associated with said actor; and a second piece of information (102, 104) signed by a temporary certificate provided by a security server (400), said first and second items being associated with a timestamp within said database.
