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.

Traceability of a multi-actor job string by block chain, allowing at least two levels of confidence in the information stored

Computing systems and methods for the creation and management of authorizations of blockchain objects. Systems and methods managed by a controlled number of governing entities allow the management of access authorizations for an object connected to a varying group of services. Systems and methods therefore have numerous advantages including strong inter-operability, strong resilience, confidentiality, autonomy, ensured data integrity and traceability.
