Definitions

  • the present invention relates to an electronic telephone device. Its generally flat and ordinarily round shape allows to qualify it as a "token”.
  • the invention finds a particular application in payment systems for telephone services, such as in the system which is the subject of patent application EP-A-0 451 057 filed by Alain BERNARD on the day of filing of this request and titled "Telephone Service Payment System”.
  • Acoustic coupler modems are known which are capable of emitting sounds through a small speaker. This, approached the microphone of a telephone handset, allows the transmission of these sounds over the telephone network.
  • Another modem located at the other end of the link, interprets the data it receives and establishes a connection, for example with a computer.
  • the CCITT International Telegraph and Telephone Consultative Committee
  • Q23 a set of tones corresponding to the twelve digits and signs of the telephone keypad
  • encryption devices are also known, which make it possible to add to a digital signal a series of pseudo-random data evolving over time, so that the initial digital signal can only be found with knowledge of the data sequence and its evolution over time.
  • identifying a person by a code number has drawbacks because the code can be stolen.
  • the other devices are complex and bulky, in particular because they require a keyboard.
  • the size is reduced to the size of a calculator.
  • they are unable to define a period of validity, or, if you like, an expiration date.
  • the object of the present invention is precisely to remedy these drawbacks. To this end, it offers a very simple device of structure and use, without keyboard, emitting a digital message evolving in time, this device being capable of determining itself the instant when it is out of date to put itself definitively out of order.
  • the device is characterized in that the means comprises a clock giving the date and determining the expiration time of the device, the message thus depending on the first and second codes and on the date indicated by the clock.
  • the device is characterized in that the means comprises a counter whose content is incremented with each use, the message thus depending on the first and second codes and on the content of the counter.
  • all of the means making up the device of the invention are sealed in a block of solid material, having the shape of a token.
  • the switch is located on one side of the token and the speaker on the other.
  • the material used to form the block is preferably a resin or plastic.
  • the device When the device includes a clock, all the clocks of the different tokens are synchronized and set to the time during the manufacture of the token relative to a reference clock.
  • the device J comprises: an acoustic transmitter 10 controlled by a generator 12 (which can be, for example, a 300 baud modem or a multifrequency tone generator according to the Q23 standard), a memory 14, which will preferably be a random access memory, losing its content in the event of power supply shutdown, an electronic and logic circuit 16 connected to memory 14 and controlling the circuit 12.
  • the device also includes a clock 20 giving the date H (for example in minutes), and a battery 22 permanently supplying the clock 20 and the memory 14 but supplying the generator 12 only if a switch 24 has been closed by the effect of a means such than a push button 26 (or any other equivalent means).
  • the clock 20 is a circuit which, on the one hand, gives the elapsed time, counted for example in minutes from the original date of the device and, on the other hand, determines the time remaining to run until the date of expiration.
  • the clock 20 can be constituted by a time base connected, on the one hand, to a minute counter, the content H of this counter appearing on an output 21, and connected, on the other hand, to a minute counter , the zero crossing of this down counter resulting in the appearance of a reset reset signal on an output 23.
  • a period of 10 years represents 5,256,000 minutes which requires 7 digits (from 0 to 9).
  • the lifetime of a token can be 6 months, or 262,800 minutes.
  • the memory 14 contains a first code which is a code for identifying the token. It is a number N introduced during the manufacture of the token by software or by masking of an integrated circuit or by programming.
  • the memory 14 also contains a second code or key C, which is specific to the global telephone system in which the token is used. Naturally, the memory 14 can be made up of two independent memories, one storing the first code, the other the second.
  • the electronic and logic circuit 16 thus has the date H delivered by the clock 20, the identification code N and the key C specific to the global system.
  • the circuit 16 then generates a digital message M which is a function of H, N and C.
  • Those skilled in the art know algorithms for forming such messages.
  • the document US-A-4,601,011 already cited and the Bibliographical references which it contains describe means capable of implementing such algorithms and, at the other end of the line, means capable of carrying out reverse algorithms. It is therefore not necessary to go into the details of these circuits.
  • N can comprise 8 digits (from 0 to 9), which represents 100 million possible tokens; key C can also include 8; you can also use 4 check digits (for example the sum of each of the numbers H, N and C and the sum of the set).
  • the sequence constituting the message can therefore be: 7 digits for the date H, 1 check digit for the sum of 9 of the previous 7 digits, 8 digits for the C key, 1 check digit for the sum at 9 of the previous 8 digits, 8 digits for the number N, 1 check digit for the sum at 9 of the previous 8 digits and 1 digit for the sum at 9 of the three check digits.
  • the generator 12 When the message M is formed, the generator 12 consequently controls the loudspeaker 10, which emits a sequence SQ formed of a series of tones.
  • the reset reset signal deactivates the memory 14 and / or the circuit 16. The token is then out of service.
  • circuits clock, memory, logic circuit
  • clock, memory, logic circuit which are shown separated from each other in the accompanying drawing - and this for clarity - can be integrated into a single circuit.
  • functions fulfilled by these circuits can be obtained by programming a more efficient circuit such as a microprocessor or a controller.
  • all of the means shown can be molded in a resin or a plastic material to present the appearance of a token.
  • the push button then appears on one of the faces of the token, the acoustic transmitter being arranged on the other.
  • the token J is placed on the microphone 40 of a telephone handset.
  • FIG. 2 shows the general appearance of the token J of the invention, seen from the front face where the loudspeaker 10 emitting the sound sequence SQ is arranged (the rear face, hidden, corresponds to the push button).
