Abstract: A method for providing personal information of a user requested by a given online service. The method includes, by a security server of a mobile terminal operator of be user: (a) receiving a request for the personal information, including comprising a unique identifier of the user and an identifier of the online service; (b) sending, to the mobile terminal, a response authorisation request; (c) if a response authorisation confirmation is received, sending data, which is associated in a database with the unique identifier and the identifier of the online service. Each pair of a unique identifier and an online service identifier is also associated in the database with a parameter representative of a level of security required in order to confirm the response authorisation on the mobile terminal. The step (b) includes: determining the value of the parameter; and integrating the determined value in the response authorisation request.
