Abstract: Some embodiments are directed to a system for the traceability of a job string performed by multiple actors, including a database for storing the information generated for each job of the string, wherein each actor can, after having obtained a right of access to the database, add a first information element signed by a certificate obtained from a secured hardware device associated with the actor; and a second information element signed by a temporary certificate supplied by a security server, the first and second elements being associated with a timestamp in the database.
