The anonymization of data is achieved by making independent, thanks to the use of a blockchain, the identifiers of the data sources and the users on the one hand, and the personal data on the other hand. The personal data are stored at addresses indexed by their hashed values in a first database and the identifiers are stored with their corresponding access profiles in a second database. The link between these two independent databases is ensured by cryptographic elements recorded in the ledger of the blockchain.”
