  • Method and system for managing access to personal data by means of a smart contract
    Patent number: 11314891
    Abstract: A method/a system for accessing personal data using an access token server, a data server and a blockchain. The access token server generates the access rights of different users in the form of access tokens. The access token server stores an access token by transmitting it via a first transaction, to a first smart contract of the blockchain. A user can request an access authorization by transmitting a second transaction to a second smart contract that can access the token by presenting cryptographic elements to authenticate the user. A granted authorization is recorded by the second contract in the blockchain. A user may access the personal data by transmitting an access request to the data server. This interrogates the second smart contract to verify the authorization and to obtain the access token. The data server next transmits the stored personal data to a URL specified in the token.
