MEDICAL DATA ACCESS SYSTEM

In order to access a user's medical data (DonM) saved within a mobile terminal (TM) of the user which has transmitted an emergency call to a call center (CA) over a telecommunications network (RT), the mobile terminal transmits an identifier (IdU) of the user to the call center, which assigns an authorized person to the user and transmits an identifier (IdP) of the authorized person and the users identifier (IdU) to a communication server (SC). The server generates a key (Ku) based on the authorized person's identifier and on the users identifier and transmits the key to the mobile terminal (TM) and to a terminal (TC) of the authorized person, in order to unlock access to the medical data (DonM) by way of the key (Ku).
