- FIG. 1 a schematic perspective view of the system and of the method according to the invention
- FIG. 4 in the form of a block diagram, the first variant embodiment, characterized in that the IT services of the service provider downloads conversion software into the multimedia terminal,
- FIG. 6 shows, in the form of a block diagram, the said third alternative embodiment, characterized in that the IT services of the service provider receive bits generated by the multimedia terminal by means of specific software.
- the system and the method according to the invention are now presented in relation to FIG. 1.
- the system and method according to the invention allow users 11 of the Internet type computer network 15 having multimedia terminals 16 comprising a microphone 17, to access the services 30 that the service provider 12 offers to the users in a safe and rapid manner.
- the multimedia terminal 16 located remotely from the computer services 18 of the service provider 12, is connected to the computer network of the Internet type 15.
- the system includes a card 10, in credit card format, personalized with specific identifiers for each card and for each subscriber 1 1.
- This card is made available to subscribed users 1 1 by the service provider 12 and its services 40
- the card 10 comprises transmission means, in particular a loudspeaker 13 emitting brief acoustic identification signals 20, of the DTMF type. These signals are emitted when the emission means 13 and the organs which control them are actuated by the client by means of a button 14 accessible from the outside of the card (not visible in FIG. 1 as located on the other side of the card).
- These transmission means 13 are excited by a DTMF signal generator 99, controlled by a microprocessor 104 supplied by a battery 106 and controlled by a resonator 107.
- the microprocessor 104 contained in the card comprises encryption means 103 making it possible to encrypt, at least in part, the acoustic signals 20, comprising an encryption algorithm 108 and identifiers 109 specific for each card 10 and for each subscriber 11, in particular the secret key 250 used by encryption algorithm 108.
- the acoustic signals 20 are received by the microphone 17 of the telephone handset, against which the customer attaches the card 10.
- the system also comprises means 19 for transmitting the acoustic signals 20, located in the multimedia terminal 16. These transmission means 19 transmit remotely the acoustic signals, after processing and conversion into electronic signals, via the computer network of the type Internet 15.
- the system also includes computer means 21, dependent on the computer services 18 of the service provider, connected to the computer network of the Internet type 15 and receiving the signals coming from the multimedia terminals 16.
- the computer means 21 include:
- a database 23 containing the references of the cards and subscribers and their identification data, processing means 24 and comparison means 25 of the electronic signals and of the identification data contained in the database 23,
- the microprocessor 104 and the encryption means 103 are designed so that the acoustic signal 20 varies with each operation. Indeed, encrypt an identification code that is transformed into a sequence information, incomprehensible to everyone, and that only the holder of the encryption key, will decrypt. But that absolutely does not prevent the copy of the encrypted identification code, either during its acoustic transmission (tape recorder), or by hacking of the telephone line. This copy, used unduly by a fraudster, will be treated by the receiving system as having all the characteristics of the original, then interpreted in order to verify the identifiers of the card. The problem is therefore the following: how to make any attempt at reproduction impossible?
- the computer means 21 are awaiting the encrypted result C (n). If they actually receive the message C (n), it validates the operation. But the computer means 21 can receive a different message, in fact the user of the card can have actuated the transmission means 13 of the card several times, by play, by mistake, so that the card is in the situation to transmit the encrypted result C (n + p) when it is next used with the computer means 21. If the computer means 21 receive a different message, they search forward, in the list of successive encrypted results, if there is a message C (n + p) identical to that received. To resolve the ambiguity "is this an authentic message sent by the sender?" or "is this a fraudulent message?", the solution is to request or wait for the next message to be sent.
- the microprocessor 104 on board the card 10 includes an incremental counter 105.
- the incremental counter 105 is incremented by one or more units. Obviously, like a ratchet wheel, it cannot go back, it can only advance with each use.
- the state C (p, n) 242 of the counter 105 enters into the calculation of the encrypted message 244 transmitted by the transmission means 13.
- the coded part S (p, n) 241 is calculated by the algorithm 108 (whose equivalent algorithm 247 is stored in the computer means 21) by means of the secret key 250 specific to each card and of the state C (p, n) 242 of the counter 105.
- the card 10 transmits, in addition to the identification number I (p) 240 of the card and the encrypted identification code S (p, n) 241, the state C (p, n) 242 of its incremental counter 105 at each program.
- the computer means 21 store 230, in the database 23, the state C (p, n) 242 of the incremental counter 105 during the last validated operation.
- the comparison means 25 of the computer means 21 can compare 245 the information received relating to the state C (p, n) 242 of the counter 105, to the previous information received C (p, m) 246 and kept in memory 230, 23. a) - If the state C (p, n) 242 of the counter 105 (fig. 2) expressed in the message 244 is strictly greater (n> m) than that C ( p, m) 246 previously received, then message 244 is accepted and analysis continues.
- the computer means 21 make it possible to read the fixed part I (p) 240 and to search in their own database 23, 230 for the corresponding secret key of the card.
- the calculation means 239 of the processing means 24 can then, by means of the algorithm 247, of the state of the counter C (p, n) 242 and the secret key Key (p) 250, proceed to the calculation of the encrypted code expected by the computer means 21.
- the encrypted code S '(p, n) 248 thus calculated is compared 249 to that actually received S (p, n ) 241, by the comparison means 25.
- This method and these means therefore make it possible to validate or invalidate the message 244, without it being necessary for the user of the card to actuate it several times, as this is the case in the embodiment described above.
- the frame 244 transmitted contains, for a given card (p),
- the computer means 21 allow, for a given card (p), to:
- the system further comprises second comparison means 26.
- These comparison means make it possible to compare a personal confidential code with the subscriber contained in the database with the confidential code issued by the subscriber.
- This code is transmitted by means of a keyboard 27 associated with the multimedia terminal 16 and / or the card 10 and transmitted to the IT means of the service provider, by the computer communication network 15.
- the service provider has the assurance that the caller 1 1 is indeed the person authorized to enter into contact with his services. A stolen card cannot be used by the thief for lack of knowing the confidential code.
- the computer means 21 include: - software validation means 21a of the orders given by the subscriber to the service provider, after detection of an encrypted acoustic signal emitted by the card actuated by the subscriber,
- FIGS. 4, 5 and 6 we will now describe three alternative embodiments which make it possible to transmit the acoustic identification signals 20 to the IT department 18 of the service provider 12.
- the same references have been used in these figures to designate the bodies and the means which have been described in connection with the figure 1.
- the computer means 21, dependent on the computer services 18 of the service provider comprise means for downloading 200 in the multimedia terminal 16, software for converting the sound file into bits. So that the signals from the multimedia terminal 16 are in the form of a sequence of bits.
- the multimedia terminal 16 comprises means for converting and transmitting 300 acoustic identification signals received by the microphone of the multimedia terminal, in the form of a sound file. This sound file is transmitted in particular after reception of a signal emitted by the IT services 18 of the service provider. This signal is issued after the telephone connection has been established between the terminal and the IT department.
- the processing of the sound file and its transformation into a sequence of bits are carried out by the computer means 21 of the computer services 8 of the service provider.
- the service provider provides the subscriber with conversion software (400) for the latter to enter his multimedia terminal 16.
- This conversion software transforms the acoustic signals received and transmitted by the microphone 17 of the multimedia terminal 16, in digital signals transmissible remotely by means of the computer network of the Internet type 15.
