Definitions
- the invention relates to portable unidirectional pager receivers, comprising reception means for receiving radio messages, a memory for storing these messages, a screen, a keyboard, a transmitter of sound signals and an electronic central unit, these receivers being provided. to display on their screen at least some of the messages they receive, the sound signal transmitter being designed to transmit sound signals in several frequencies, and the central unit being provided for: - recognizing, among the messages received, by minus a fraction of a specific message, known as a "primary code", intended to cause the emission of a sound signal coded by the transmitter of sound signals,
- the sound signal transmitter transmits a coded sound signal which comprises a series of elementary sound signals and which is determined by the central unit by at least as a function of the primary code, this coded sound signal being variable as a function of the primary code.
- a portable paging receiver of the kind in question is essentially characterized in that the central unit is further provided for: - recognizing at least one primary code known as "certification" and displaying by the screen a message asking the user of said receiver to dial a secondary code using the keyboard,
- the additional code is an internal code contained in the memory
- the receiver also includes an interface enabling dialogue with an external microprocessor card, and the central unit is further provided for:
- the invention also relates to a first method of identifying people at a distance using a portable paging receiver as defined above which receives radio messages from at least one transmitting station, this method comprising the following steps :
- step (b) consists in causing the transmitter of the receiver's sound signals to transmit a series of elementary sound signals representative of the identification code, the signal transmitter then being placed in the vicinity of a microphone belonging to the telephone set.
- the invention also relates to a second method for identifying people at a distance using a portable paging receiver which receives radio messages from at least one transmitting station, this process comprising the following stages:
- the identification code is stored in the microprocessor card, and step (b ') consists in having the identification code of the microprocessor card read by the central unit via the interface, and to cause the transmitter of sound signals to transmit a series of elementary sound signals which is representative of the identification code, the transmitter of sound signals being then placed in the vicinity of a microphone belonging to the telephone set.
- the above remote identification methods can advantageously include a subsequent step which consists in authorizing a remote payment operation only if the existence of the predetermined relationship between the identification code, the primary code has been verified. certification, and the coded audio signal.
- FIG. 1 is a view of an example of a portable paging receiver according to the invention
- FIG. 2 is an example of a functional diagram of the receiver of Figure 1, in its environment.
- the unidirectional paging receiver consists of a portable box 1 such as that shown in FIG. 1, which is designed to receive coded radio messages transmitted by a remote transmitting station (FIG. 2), the coding of the radio messages that can be produced, for example, in accordance with the ERMES standard (EEC Directives 85/374 and 92 / 59- ETS standard 300.133-1 to -7 published by the European Telecommunication Standard Institute).
- ERMES EEC Directives 85/374 and 92 / 59- ETS standard 300.133-1 to -7 published by the European Telecommunication Standard Institute
- This case has a reduced size, for example of the order of a few centimeters in its largest dimension, so that it can be held in one hand.
- the box 1 has a screen 2 for displaying all or part of the messages received over the air which are intended for said box, and a keyboard 3 with a few keys which makes it possible in particular to control the display of these messages, their erasure, etc.
- the keyboard 3 can comprise for example four keys, know:
- FIG. 2 shows in particular a functional diagram of the receiver unit 1 which conventionally comprises:
- an amplifier 5 connected to the antenna 4 to amplify the signals received by the antenna 4, a demodulator 6 connected to the output of the amplifier 5 to demodulate the amplified signals coming from this amplifier,
- an electronic central unit 7 generally constituted by a microprocessor, connected to the output of the demodulator 6 to receive, decode and process the demodulated signals coming from the demodulator 6, the central unit 7 being connected to the screen 2 and to the keyboard 3,
- the receiver unit 1 can also comprise a reader 41 of microprocessor card, which opens outside the receiver unit by a slot (not shown) in which one can insert a microprocessor card 40 (see FIG. 1) .
- the reader 41 is then connected to the central unit 7, and this central unit is programmed to communicate with the microprocessor of the card 40, as will be explained in more detail below.
- the receiver unit 1 can be used to identify a person at a distance, which in particular, but not exclusively, makes it possible to secure remote payment operations, in particular by bank card.
- this remote person identification mode can be implemented in a receiver unit 1 not comprising a microprocessor card reader 41, or also to secure a remote payment transaction other than by bank card, or to secure a remote payment transaction by bank card when the bank card does not include a microprocessor or is not compatible with the reader 41.
- this contact can verify the identity of the user of the receiver unit 1 as follows:
- the user of the receiver unit 1 gives his interlocutor 34 an identification code which will generally consist of the personal paging number of the user, this number making it possible to send radio messages to the receiver unit 1, then l 'contact 34 between this identification code in a computer system 36 (possibly, the identification code can be sent directly to computer system 36 after connection of this system to the switched telephone network 30, by sending from the top- speaker 9 a series of elementary sound signals corresponding, in the "voice frequency" numbering system specific to the telephone network, to the various digits making up the identification code), the computer system 36 is connected by via the switched telephone network 30 at the transmitting station 20, and transmits to the receiver unit 1 a message comprising a sequence of characters, called "primary certification code", - the central unit 7 is then programmed to cause the loudspeaker 9 to emit an audible alert signal, and to display on the screen 2 a message such as "dial your secret code",
- the user then dials his secret code on the receiver unit 1 by means of the keyboard 3, for example by successively selecting numbers and / or letters from a set of numbers and / or letters displayed on the screen 2, using the direction keys 3a and 3b and successively validating the different numbers or letters selected by means of the validation key 3c, or even using only the direction keys 3a and 3b, the secret code then being determined by a particular sequence successive presses on keys 3b and 3c (for example: two presses on key 3a, four presses on key 3b, one press on key 3a and one press on key 3b),
- the central unit 7 is programmed to determine a so-called "resulting" code which is a function of the primary certification code received by paging, of an internal code contained in the memory 8 and of the secret code entered by the user, and to cause this resulting code to be transmitted in the form of a coded sound signal composed of a series of elementary sound signals by the loudspeaker 9, this emission being triggered by a command from the user consisting for example of pressing the validation key 3c of the keyboard, after the user has approached the speaker 9 of the microphone 32b of the telephone set 32,
- the computer system 36 receives the resulting code by the switched telephone network 30, and checks whether there is a predetermined relationship between the code identification, the primary certification code and the resulting code,
- the computer system 36 authorizes remote payment if this predetermined relationship is verified.
- the voice frequency numbering system used will generally be the so-called “DTMF” system (Dual Tone Multifrequency), in which each sound signal comprises two superimposed frequencies.
- DTMF Double Tone Multifrequency
- remote person identification mode which has just been described is not limited to remote payment by bank card, but can be used in all applications where it is necessary to identify a person.
- the identity of the user of the receiver unit 1 can be verified as follows, in particular for making a remote payment to the aforementioned contact 34:
- the user of the receiver unit 1 plugs his microprocessor card 40 into the reader 41,
- the user of the receiver unit 1 gives his interlocutor 34 the number of his microprocessor card, which may possibly be a bank card or another payment card, and it also optionally gives the call partner 34 his personal paging number if the number of the microprocessor card 40 is not sufficient for the contact 34 to send a radio message to the receiver unit 1,
- the computer system 36 connects via the switched telephone network 30 to the transmission station 20, and transmits to the receiver unit 1 a message comprising a predetermined sequence of characters, called "primary certification code",
- this radio message is recognized by the receiver unit 1 as being intended for it, the recognition of this destination preferably taking place solely by virtue of the number of the microprocessor card 40, with which the central unit 7 communicates via the reader 41, in which case the user of the receiver unit 1 can content himself with giving only his microprocessor card number at the start of the procedure, as explained above,
- the central unit 7 is then programmed to transmit an "initial" code which is a function of the primary certification code (this initial code can simply be the primary certification code) to the microprocessor card 40 by means of the reader 41, and to cause the loudspeaker 9 to emit an audible alert signal and to display on the screen 2 a message such as: "dial your secret code", - the user then dials his secret code on the receiver unit 1 using the keyboard 3 as already explained above,
- the central unit 7 is programmed to transmit the secret code to the microprocessor card 40 by means of the reader 41, - the microprocessor card 40 determines a so-called "resulting" code which is function of the initial code, an internal code contained in the microprocessor card 40 and the secret code entered by the user,
- the resulting code is transmitted to the central unit 7 by means of the reader 41, and the central unit 7 determines a coded sound signal representative of the resulting code,
- the central unit 7 transmits the sound signal coded by the loudspeaker 9 on command of the user, for example when the user presses the validation key 3c of the keyboard, the loudspeaker 9 then being placed in the vicinity the microphone 32b of the telephone set 32,
- the computer system 36 receives the coded sound signal representative of the resulting code, it reconstitutes the resulting code, and it checks whether there is a predetermined relationship between the number of the microprocessor card, the primary certification code and the code resulting,
- the computer system 36 authorizes remote payment if this predetermined relationship is verified.
- the method of determining the resulting code and verifying said predetermined relationship are well known in the state of the art, as explained above.
