  A description will now be given, with reference to FIG. 1, of the system and the method for downloading a sound signal according to the present invention.

  As can be seen in FIG. 1, the system according to the present invention comprises: - a first telecommunications equipment 1, - a second telecommunications equipment 2, - and a data transmission means 3 which is, in the example shown, a mobile telecommunications network, for example of the GSM type, comprising an SMS message center ("Short Message") 3a which is intended, in a manner known per se, to manage the reception and sending of SMS messages. The first telecommunications equipment 1 is, in the example shown, a conventional mobile telephone, for example of the GSM type, which comprises in a known manner as such: At a memory 4, * a communication interface 5 with the second equipment 25 of telecommunications 2, via the GSM network 3, said interface being, in the example shown, of SMS type, * a bus 6 connecting the memory 4 to the communication interface 5, * a digital analog converter 7a connected to the bus 6, * a speaker 8a connected to the digital analog converter 30 7, * an analog digital converter 7b connected to the bus 6, * a microphone 8b connected to the analog to digital converter 7b, * a keyboard 9 connected to the bus 6,

  * and a screen 10 connected to bus 6.

  The server 2, to which the holder A of the mobile telephone 1 has previously subscribed, comprises: * an SMS interface 11 with the operator of the GSM network 3, ò an application server 12 connected to the interface 11 and intended to process SMS requests from the mobile phone 1, 10 e a database 13 connected to the server 12 and containing a directory of confidential data relating in particular to the holder A of the mobile phone 1, * a digital analog converter 14 connected to the server 12 ,

  * and a loudspeaker 15 connected to the converter 14. 15 As mentioned above in the description, the

  confidential data define the right of holder A of mobile phone 1 to acquire goods or use a service. As mentioned above, this is data from an "electronic ticket".

  In the example shown, holder A can assert his right 20 only once (for example, purchase of a cinema seat) or over a period of

  predetermined time (for example, access to a parking space).

  The holder A of the mobile phone 1, who wishes to acquire an electronic ticket from the server 2, dials on the keyboard 9 of the mobile phone 1

  the server access number 08 xx xx xx 2.

  Once the server 2 has been contacted, the holder A sends towards the server 2, via the SMS interface 5, a request requesting the server 2 to download, to the mobile phone 1, an audible signal containing the

  confidential data relating to holder A of the mobile telephone 1.

  In the example shown, said request is in the form of a short SMS message, 16, entitled for example: "sending electronic electronic ticket?>". Such a request 16 contains, in a manner known as such, the

  MSISDN identification number of holder A of the mobile phone 1.

  The request 16 is received by the SMS interface 11 after having passed through

  in the SMS message center 3a.

  The SMS interface 11 transmits the request 16 to the application server 5 12 which includes a program designed to allow, following the reception of the request 16, the verification that the holder A of the mobile telephone 1 is authorized to receive the electronic ticket audio containing confidential data

  relating to holder A of the mobile telephone 1.

  In a manner known as such, such a verification consists in comparing whether the identification number MSISDN assigned to the message 16 is the same as the identification number MSISDN previously recorded in the database 13 of the server 2 at time of holder A's subscription

mobile phone 1.

  If the verification proves to be correct, the application server 12 sends to the database 13 a request, for example of the SQL type, according to which the confidential data of the corresponding electronic ticket are requested.

  to the MSISDN identification number contained in message 16.

  If such a correspondence exists, the database 13 sends in

  response to the application server 12 said confidential data.

  The application server 12 then transmits this data to the

  digital to analog converter 14.

  The analog signal produced by the converter 14 is then broadcast

through the speaker 15.

  In the example shown, which is in no way limiting, this sound signal is of the DTMF (Dual Tone Multi Frequency) type. It contains in particular an identification number of the considered electronic ticket download service, the MSISDN identification number of holder A of the telephone.

  mobile 1, as well as an electronic signature.

  The DTMF signal is picked up by the microphone 8b of the mobile phone 30 1, then converted by the analog to digital converter 7b into a sequence

  of samples which are transmitted to memory 4, via bus 6.

  We will now describe, with reference to FIG. 2, the system and the method for controlling confidential data relating to holder A of the

mobile phone 1.

  As can be seen in FIG. 2, the system according to the present invention comprises: - telecommunications equipment which is the mobile telephone 1 of FIG. 1,

  - And control means 17 for confidential data relating to: 10 holder A of the mobile telephone 1.

  In the example shown, the control means 17 comprise a terminal which comprises: ò a microphone 18, to an analog digital converter 19 connected to the microphone 15, * a bus 20 connected to the analog digital converter 19, * a microprocessor 21 connected on the bus 20, * a comparator 22 connected to the microprocessor 21, * and a database 23 connected to the comparator 22. 20 The database 23 comprises a plurality of data files

  confidential corresponding to users of the system.

  As mentioned above in the description, such data

  confidential define the right of a system user to acquire property

or to use a service.

  Holder A of mobile phone 1, who wishes to acquire a property

  or use a service, go to terminal 17.

  He then selects from a drop-down menu that appears on screen 10,

  the operation entitled "broadcasting of electronic sound tickets". Such an operation has been programmed beforehand in data processing means 30 (not shown) of the mobile telephone 1.

  Following this selection, the holder A presses a predetermined key on the keyboard 9, which has the effect of causing the confidential data to be read from the memory 4 by said processing means.

  relating to holder A of the mobile telephone 1.

  The processing means submit this data to the digital analog converter 7a via the bus 6. The analog signal produced by the converter 7a is then broadcast by the loudspeaker 8a, for example in the form of a DTMF signal, and picked up by

the microphone 18 of terminal 17.

  The analog signal is then converted by the analog to digital converter 19 into a plurality of data which are transmitted to the

  microprocessor 21, via bus 20.

  The microprocessor 21 then transmits this data to the comparator 22. The comparator 22 checks whether this confidential data 15 corresponds to the confidential data contained in the database 23, which have been previously recorded by the holder A of the telephone

mobile 1.

  If the result of this verification is positive, terminal 17 allows the

  holder A of mobile telephone 1 to acquire a good supplied by the service provider or to use a service offered by said provider.

  It goes without saying that the embodiment which has been described above has been

  given purely by way of indication and in no way limiting, and that numerous modifications can be easily made by those skilled in the art without departing from the scope of the invention.

  This is how the verification of confidential data could be carried out, not in terminal 17, but in equipment remote from the latter. he
