A method for identifying an individual equipped with a mobile terminal in a system comprising one or more items of control equipment EQ, characterised in that it comprises at least the following steps: - the individual granting their consent to an item of control equipment EQ and self-authenticating; - establishing a logical association between the item of equipment and the mobile terminal of an individual when the distance between the individual and the item of equipment EQ is below a threshold value; - the item of equipment EQ launching a biometric data acquisition sequence; - the mobile terminal transmitting a characteristic element to a storage server S 2 in order to retrieve biometric/biographic data; - the storage server S 2 checking the existence of a session token with an authentication server S 4 and consulting a table of correspondence containing the link to encrypted data characteristic of the individual; - the storage server transmitting encrypted data E" to the mobile terminal, which uses a private key of the individual to decrypt the data E"; - transmitting the decrypted data E' to the authentication server, which executes the following steps: - requesting, from an authority S 3, to decrypt the encrypted data E' with a private key of the authority S 3, in order to obtain the specific data E of the individual and at the same time request to check the signature of the data E in order to guarantee its authenticity; - transmitting the data E and the identifier of the item of equipment EQ to a biometric server S 1; - the biometric server S 1 retrieving the data acquired by the item of equipment EQ and comparing this data with the twice-decrypted data E in order to authenticate the individual; - transmitting the result of the authentication to the server S 4, which notifies the item of equipment EQ. - the individual granting their consent to an item of control equipment EQ and self-authenticating; - establishing a logical association between the item of equipment and the mobile terminal of an individual when the distance between the individual and the item of equipment EQ is below a threshold value; - the item of equipment EQ launching a biometric data acquisition sequence; - the mobile terminal transmitting a characteristic element to a storage server S 2 in order to retrieve biometric/biographic data; - the storage server S 2 checking the existence of a session token with an authentication server S 4 and consulting a table of correspondence containing the link to encrypted data characteristic of the individual; - the storage server transmitting encrypted data E" to the mobile terminal, which uses a private key of the individual to decrypt the data E"; - transmitting the decrypted data E' to the authentication server, which executes the following steps: - requesting, from an authority S 3, to decrypt the encrypted data E' with a private key of the authority S 3, in order to obtain the specific data E of the individual and at the same time request to check the signature of the data E in order to guarantee its authenticity; - transmitting the data E and the identifier of the item of equipment EQ to a biometric server S 1; - the biometric server S 1 retrieving the data acquired by the item of equipment EQ and comparing this data with the twice-decrypted data E in order to authenticate the individual; - transmitting the result of the authentication to the server S 4, which notifies the item of equipment EQ.
