creating (E 1 ) a user account containing identification data of said user ( 1 );
installing (E 2 ) in said mobile terminal ( 2 ) a software application for accessing said plurality of services;
creating (E 5 ), in the mobile terminal ( 2 ), by using said software application, an image ( 7 ) containing at least one software application identifier;
decoding (E 6 ), by using a secure management entity ( 3 ) of said software application, data contained in the image ( 7 ); and
enabling (E 8 ) or not enabling (E 9 ) the user ( 1 ) to access said plurality of services according to the decoded data.
2. Method according to claim 1 , characterized in that it also comprises a step consisting in activating (E 3 ), in the mobile terminal ( 2 ), said software application, by associating said software application identifier with said user account.
3. Method according to claim 1 , characterized in that it also comprises, prior to the step for creation (E 5 ) of the image, a step (E 4 ) consisting in entering into the mobile terminal ( 2 ) a user personal identification code.
4. Method according to claim 1 , characterized in that the step for creation (E 5 ) of the image includes an encryption step (E 51 ) consisting in encrypting at least the software application identifier.
5. Method according to claim 4 , characterized in that the encryption step (E 51 ) consists in also encrypting said user personal identification code.
6. Method according to claim 4 , characterized in that, during the encryption step (E 51 ), a public key encryption algorithm is used and in that the decoding step (E 6 ) includes a decryption step (E 61 ) consisting in decrypting the data contained in the image ( 7 ) by using a private key associated with said public key.
7. Method according to claim 1 , characterized in that the user identification data contained in the user account comprises at least one software application identifier.
8. Method according to claim 7 , characterized in that the user identification data comprises a single software application identifier, associated with said at least one mobile terminal ( 2 ).
9. Method according to claim 7 , characterized in that the user has a number of mobile terminals and in that the user identification data comprises a plurality of software application identifiers which are respectively associated with said mobile terminals.
10. Method according to claim 1 , characterized in that said image ( 7 ) created in said mobile terminal ( 2 ) has a predetermined validity period.
11. Method according to claim 1 , characterized in that the software application identifier comprises a series of alphanumeric characters.
12. Method according to claim 3 , characterized in that the user personal identification code comprises a series of alphanumeric characters.
13. Method according to claim 1 , characterized in that said installation step (E 2 ) is performed at least partially from the secure management entity ( 3 ).
14. Method according to claim 1 , characterized in that said image ( 7 ) is a one- or two-dimensional bar code.
15. Secure management device ( 3 ) of a software application enabling a user ( 1 ) of at least one mobile terminal ( 2 ) to access a plurality of services, characterized in that it comprises:
means ( 392 ) for decoding data contained in an image ( 7 ) containing at least one application identifier, said image having been created previously in the mobile terminal ( 2 ) by using said software application; and
means ( 393 ) for enabling or not enabling the user ( 1 ) to access said plurality of services according to the decoded data.
16. Device according to claim 15 , characterized in that it also comprises means ( 391 ) for at least partially activating said software application in the mobile terminal ( 2 ).
17. Device according to claim 15 , characterized in that it also comprises public key and private key cryptography means ( 394 ).
