Abstract: A method for accessing a service supplied on a mobile terminal by an application server contributing to supplying the service. The method is implemented by the mobile terminal and includes: transmitting a request having a subscriber identifier of a subscriber of a subscription with a mobile operator, the subscriber identifier being based on a piece of information supplied by a security module of the mobile terminal, and inserted in the request without intervention of the user; receiving a response including an identification code relating to the subscriber identifier; transmitting an authentication request Including the identification code, the request being transmitted to an authentication server of the mobile operator; receiving an authentication response including an authentication code relating to the identification code; and transmitting a service access request including the authentication code to the application server.

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.
