Description

Method for requesting pairing of a first communicating object with a second communicating object, method for processing a pairing request, devices, communicating objects and associated computer programs. FIELD OF THE DISCLOSURE The field of the invention is that of telecommunications, and more particularly of wireless telecommunications. The present invention relates to a communicating object adapted to come into physical contact with a second communicating object and to request the establishment of a wireless communication with the second communicating object by emitting a predetermined vibratory signal. The invention applies particularly advantageously to mobile terminals, but also to any connected object belonging to the home or professional environment of a user. 2. Prior Art In recent years we have witnessed the explosion of uses around so-called communicating or connected objects. Communicating object means any object equipped with communication means, for example IP (for "Internet Protocol", in English) allowing it to exchange data with other communicating objects. It is a question of terminals of users like computer, tablet, smart mobile phone ("smartphone", in English), that of everyday objects which are not natively communicating, like a TV, a stereo, a refrigerator, a lamp or an oven, but which have been equipped with a suitable wireless communication module.

Communications between communicating objects of a user take an increasingly important place in the life of this user, especially because they can significantly enrich the services offered to him. For example, the user can establish a wireless communication between his phone and his computer, or between his tablet and his television to transfer multimedia content. For home use, the user can remotely control the opening or closing of its outer shutters, or adjust the sensitivity of its heating. The pairing between two communicating objects is therefore essential in this context. To signify means to link, to make dependent on one another, two complementary elements. In order to exchange data, communicating objects must be paired by activating the recognition of authorized communicating objects in their neighborhood. From a communicating object, the other communicating object is recognized by the exchange of a pairing code. In some cases, the code is free, and it is sufficient for the two communicating objects to enter the same code. In other cases, the code is fixed by one of the two objects (the one that does not have a keyboard, for example), and the other must know it to connect to it. Following a first pairing, the pairing code of the second communicating object can be stored by the first, which facilitates subsequent pairing. Conventional wireless communication techniques can be implemented with a short-range connection of Bluetooth, Zigbee or Wi-Fi type. It can also be an infrared connection. As for the pairing code, it can be a WEP key ("Wired Equivalent Privacy," in English) or WPA ("Wi-Fi Protected Access", for example). These wireless communication techniques therefore require a prior configuration of the two communicating objects which is not trivial for the end user. In addition, for the establishment of the wireless connection, the pairing code can be exchanged with enough distance to allow the connection of two communicating objects located in separate apartments, which is not necessarily desirable. Finally, entering the pairing code requires a keyboard and a control screen, which are not available on some communicating objects, such as a lamp or a refrigerator, for example. It is known from the US patent application published under the number US2011 / 0191237, a method of establishing a communication between a first and a second terminal, both equipped with an accelerometer. In relation to FIG. 1, when the two terminals UE1 and UE2 come into physical contact, they each generate interaction data DI1 and D12 by means of their respective accelerometers, which they transmit to a remote server RS via the intermediary of a RO operator network. If the RS server determines from the transmitted data DI1 and D12 that there has been physical contact between the two terminals, it allows the establishment of a wireless communication between them. 3. Disadvantages of the Prior Art One advantage of this solution is that it prevents users from entering a key. However, this solution has the disadvantage of requiring the intervention of a remote server to determine that there has been physical contact between the two terminals and allow the establishment of communication between them. The implementation of the invention is therefore based on a specific network architecture. It is also essential that, in a prior step, the terminals in question have previously registered with this server and identified as being connectable to one another.

Another disadvantage of this solution is that it is based on simultaneous energy transfer from the two terminals to each other. As a result, it is not enough simply to physically contact the two terminals to trigger the pairing request. To cause simultaneous energy transfer from one to the other expected by the remote server, the user will be tempted to clash. This solution is not suitable for fragile communicating objects, such as a lamp or a stereo, which could be damaged by such manipulation. Note also that it is not easy for the user or users on the one hand to measure the force of the shock to be applied between the two communicating objects and on the other hand to realize if the shock created has been enough to trigger the desired pairing process. The user may therefore have to renew the shock several times unnecessarily, as long as he does not have a return from the terminals indicating that the pairing is being established. Conversely, a synchronized movement of each of the two terminals in the direction of the other could also be interpreted by the server as a physical contact triggering a pairing procedure, which is not necessarily desirable. As a result, this step of contacting the two terminals, remotely controlled by a server and initiating the pairing procedure, is not obvious to master for a user, moreover if he suffers from a disability. , in particular visual. 4. OBJECTIVES OF THE INVENTION The invention particularly aims to overcome these disadvantages of the prior art. More specifically, an object of the invention is to provide a simple and nevertheless secure solution, allowing one or more users to trigger the pairing of any two communicating objects, without having to enter any pairing code during the pairing procedure itself. Another object of the invention is to provide a solution for triggering a pairing of any two communicating objects on the basis of simple handling and accessible to any user, even if he is disabled.

Another object of the invention is to allow the pairing of two communicating objects without requiring communication resources of an operator network. Yet another object of the invention is to provide the user with a quick feedback on the actual triggering of the pairing procedure. . DISCLOSURE OF THE INVENTION These objectives, as well as others which will appear subsequently, are achieved by means of a method for requesting the pairing of a first object communicating with a second communicating object. invention is remarkable in that it comprises, following the physical contact by a user of the first object with the second object, a transmitting step by the first communicating object of a pairing request with the second object communicating in the form of a vibratory signal whose inertial signature is representative of a predetermined pairing code, intended to be recognized by the second communicating object. With the invention, the first communicating object, once placed in physical contact with the second communicating object by a user, transmits as a pairing request a vibratory signal whose inertial signature is representative of a predetermined pairing code. , intended to be recognized by the second communicating object.

Unlike the prior art, the triggering event of a pairing is not the fact of clashing the two communicating objects, but the transfer of a vibratory signal between two communicating objects placed in physical contact. In addition, the vibratory signal in question does not constitute a simple transfer of energy from the first communicating object to the second communicating object. On the contrary, it is representative of relevant information. Its inertial signature is unique and representative of a predetermined pairing code. For pairing to succeed, this predetermined pairing code must correspond precisely to that expected by the second communicating object. The pairing procedure according to the invention is therefore completely secure. This vibratory signal is easily perceptible by the user, either because he kept a physical contact with the first communicating object, or because he hears the noise caused by the vibration of the first object on the second object. Once he has placed the first communicating object on the second and he has perceived the vibration, the user knows that the attempt to pair is initiated. The invention therefore proposes an entirely new and inventive approach to the pairing of two communicating objects, by transfer of vibrations representative of a pairing code between the two communicating objects placed in physical contact. According to a first aspect, the vibratory signal comprises at least one waveform of predetermined frequency. One advantage is that the vibratory signal, although of very simple form, nevertheless generates a unique inertial signature, which can be previously associated with a predetermined pairing code. Another advantage is that the predetermined pairing code can not be deduced from the received vibratory signal, the vibratory signal and the predetermined pairing code being not linked by any mathematical relationship, making it possible to obtain one from the other.

In another aspect, the predetermined pairing code comprises a sequence of alphanumeric characters and the vibratory signal comprises at least one predetermined frequency waveform sequence, a unit waveform being representative of an alphanumeric character of said code. . In this embodiment of the invention, a pairing code consisting of a sequence of hexadecimal characters is considered and each hexadecimal character used in the pairing code of the second object is associated with a specific waveform. The sequence of hexadecimal characters forming the pairing code is then represented by the concatenation of specific vibratory waveforms, such as a word formed from the letters of the alphabet.

A first advantage is to allow a new form of coding of a pairing code. Another advantage is that one can, as with a dictionary, represent a large number of pairing codes using a vibratory signal. The various aspects of the process which have just been described can of course be implemented independently or in combination.

The invention also relates to a device for requesting pairing of a first communicating object. The device according to the invention is remarkable in that it comprises a unit for transmitting a pairing request in the form of a vibratory signal whose inertial signature is representative of a predetermined pairing code intended to to be recognized by the second communicating object. Such a device is able to implement the pairing request method according to the invention, which has just been described. Advantageously, this device can be integrated with the first communicating object. The invention therefore also relates to a communicating object capable of implementing the pairing request device which has just been described. Alternatively, the pairing request device according to the invention can be integrated with a pairing module independent of the first communicating object, but which is connected to this object. The invention therefore also relates to a pairing request module adapted to implement the pairing request device which has just been described. The invention also relates to a method of processing a request for pairing a first communicating object in physical contact with a second communicating object. Such a method is remarkable in that it comprises, after receiving a pairing request transmitted by the first communicating object in the form of a predetermined vibratory signal, intended to be recognized by the second communicating object, said The method comprises the following steps: determining an inertial signature of the vibratory signal; comparing the determined inertial signature with a reference inertial signature representative of a predetermined pairing code; - In case of correspondence between the determined inertial signature and the reference inertial signature, activation of the pairing requested by said first communicating object. With the invention, the second object, in physical contact with the first, receives the vibratory signal representative of a predetermined pairing code. The vibratory signal is analyzed using an inertial navigation module, for example present natively in the second communicating object, to determine an inertial signature of the vibratory signal received. The signature obtained is compared with the reference signature of the pairing code of the second communicating object. The pairing procedure is allowed by the second communicating object, if a match is found between the two inertial signatures.

Thus, with the invention, pairing is only allowed when the first communicating object vibrates the correct pairing code to the second communicating object.

It can be two communicating objects belonging to the same user. It can also be envisaged that the first and second objects belong to distinct users, but who know each other and have previously exchanged a pairing code. The invention imposing both a real physical contact and the transmission of a pairing code in the form of a vibratory signal between the two objects, thus offers a completely secure and simple pairing solution. to implement. Indeed, this security is not obtained at the cost of a complex network architecture and expensive in terms of resources, since the pairing according to the invention does not require the intervention of a remote server connected to an operator network during the pairing procedure, or the use of a short-range wireless link for the exchange of the pairing code. In addition, the manipulations requested from the user are simple and accessible to persons with disabilities, for example visually impaired. According to one aspect of the invention, the step of determining an inertial signature comprises the calculation of an inertial vector, the components of which are characteristic of the acceleration experienced by the second communicating object along the axes of a reference frame. the object and a step of analyzing said characteristics on at least one of said axes. The inertial navigation module is able to calculate a vector of characteristics of the acceleration experienced by the second communicating object during the reception of the vibratory signal, for example in three dimensions. If the inertial navigation module comprises an accelerometer, the vector will comprise characteristics of the linear acceleration experienced by the second communicating object along the three axes of the reference frame considered. If the inertial navigation module comprises a gyroscope, the vector will include characteristics of the angular acceleration experienced by the second communicating object along the three axes of the reference frame considered. If they include both, the inertial signature of the vibratory signal received will be determined from the two characteristic vectors obtained.

Of course, the various aspects of the method for processing a pairing request according to the invention that have just been presented can be implemented independently or in combination. The invention also relates to a device for processing a pairing request able to implement the method just described. Advantageously, this device can be integrated with the second communicating object or with a processing module of an independent pairing request, but connected to the second communicating object, by wired or short-range radio. The invention therefore also relates to a communicating object comprising an inertial navigation module and a device for processing a pairing request according to the invention. Alternatively, the device for processing a pairing request according to the invention can be integrated into a processing module of a pairing request that is independent of the second communicating object, but which is connected to this object. The invention therefore also relates to a module for processing a request for pairing a first communicating object with a second communicating object, characterized in that it comprises means of connection to said second communicating object, inertial navigation means and a device for processing a pairing request according to the invention. According to one embodiment of the invention, certain steps of the method of processing a pairing request according to the invention can also be implemented by third-party equipment connected to the second communicating object. For example, the comparison step and the decision step may advantageously be implemented by the residential gateway of the home network of a user, which makes it possible to take advantage of his memory and computing capacities, which are generally greater than that of the home network. a communicating object type furnace or lamp.

Of course, a communicating object according to the invention equipped with vibratory means and inertial navigation means can very well integrate both the pairing request device and the device for processing a pairing request which come from to be described. Advantageously, the first communicating object is a user terminal, such as an intelligent terminal terminal. Such a terminal generally integrates natively vibration means. The invention therefore also relates to a user terminal comprising a vibration module. The user terminal according to the invention is particular in that it comprises the pairing request device according to the invention, which has just been described. According to an advantageous aspect of the invention, such a terminal further comprises an inertial navigation module and the device for processing a pairing request which has just been described, according to the invention. It can therefore play both the role of first and second communicating object. The invention also relates to a pairing system comprising the first communicating object and the second communicating object that have just been described. The invention also relates to a computer program comprising instructions for carrying out the steps of a pairing request method of a first object communicating with a second communicating object as described above, when this program is executed. by a processor. Such a program can use any programming language. It can be downloaded from a communication network and / or saved on a computer-readable medium.

The invention also relates to a storage medium, readable by a processor, integrated or not to the pairing request device according to the invention, possibly removable, storing a computer program implementing a request method of pairing as described above. The invention also relates to a computer program comprising instructions for implementing a method of processing a pairing request as described above, when this program is executed by a processor. Such a program can use any programming language. It can be downloaded from a communication network and / or saved on a computer-readable medium. The invention finally relates to a storage medium, readable by a processor, integrated or not to the device for processing a pairing request according to the invention, possibly removable, storing a computer program implementing a method processing a pairing request as described above. 6.

DESCRIPTION OF A PARTICULAR EMBODIMENT OF THE INVENTION In relation to FIG. 2, two communicating objects 001 and 002 are considered. By communicant is meant that the object can establish a communication link with another communicating object, via any communication channel, for example IP type or wireless, for example by short-range radio. In the example of Figure 2, the first communicating object 001 is portable, that is to say small enough and lightweight to be moved by a user. It is preferably a mobile user terminal, intelligent terminal type or tablet or laptop. It is also considered a second communicating object, which is not necessary portable. It can also be a user terminal, mobile or not. The invention is of course not limited to terminals of this type and can be applied to any object in the home or business environment of the user, such as a connected television, a stereo, a refrigerator, a lamp or an oven. Such objects of everyday life are not natively communicating, but become so by adding a suitable communication module, preferably wireless. When the user of the first communicating object 001 wishes to pair it with the communicating object 002, he places the first communicating object 001 in physical contact with 003, for example by placing 001 on a surface of 002. The first communicating object 001 begins to emit a vibratory signal SV.

This vibratory signal is not arbitrary. It is, on the contrary, identifiable by a unique inertial signature, representative of a predetermined pairing code, intended to be recognized by the second communicating object. Note that the invention will be described below in more detail, can be implemented by means of software and / or hardware components. In this context, the terms "module" and "entity", used in this document, may correspond either to a software component, or to a hardware component, or to a set of hardware and / or software components, capable of implementing perform the function (s) described for the module or entity concerned.

In relation to FIG. 3, the steps of the pairing request method according to an exemplary embodiment of the invention are now presented. In this example, the pairing request method according to the invention is implemented in software by an application loaded into a memory of the first communicating object 1.

During a step DO, the application is first launched by a voluntary approach of the user of the first communicating object 001. During a step D1, the user of the first communicating object 001 puts it in contact with a surface of the second communicating object 002.In D2, the first communicating object 001 starts to vibrate. According to a first embodiment of the invention, launching the application triggers the emission of a vibratory signal SV. The user therefore places the first communicating object 001 in vibration on the second communicating object 002. The vibratory signal SV is in this case repeated a certain number of times, so that the second communicating object 003 can receive it in its entirety. According to one variant, the first communicating object 001 does not begin to vibrate until it has actually been placed in physical contact with the second communicating object 2. In this case, it is necessary for the first communicating object 001 to integrate a communication detection unit. this putting in contact. For example, it may be an inertial navigation module capable of providing a vector of acceleration characteristics experienced by the first communicating object when it comes into contact with the second communicating object.

This vibratory signal comprises at least one waveform emitted at at least one predetermined frequency. Examples of waveforms will be presented in the following description, in connection with FIGS. 6 and 7.

With reference to FIG. 4, the steps of the method for processing a pairing request according to an exemplary embodiment of the invention are now presented. In this example, the method of processing a pairing request according to the invention is implemented in software by an application loaded into a memory of the second communicating object 002.

During a first step TO, an application is launched by a user via a user interface of the second communicating object or a module connected to this object. Note that the user in question may be the same as that of the first communicating object 002, or another user. In the first case, it is a user in his home or professional environment, who wishes to pair two communicating objects belonging to him. In the second case, the communicating objects belong to two different users. For example, a first user of a mobile terminal is visiting a second user of a home gateway. To access the Internet, the first user wants to connect his terminal to the home gateway of the second user.

During a step T1, an inertial navigation module of the second communicating object or an independent module connected thereto, are activated to determine an inertial signature IF of the vibratory signal received by physical contact between the two communicating objects. Advantageously, such an inertial signature is obtained from vector acceleration characteristics calculated on at least one axis of a reference frame (x, y, z) of the inertial navigation module. For example, consider the z-axis perpendicular to the surface of the second object 002 in contact with the first object 001. The vibratory signal propagating from the first object to the second object along this axis, it is understood that the analysis of the characteristics the z component of the acceleration vector is particularly relevant for determining the inertial signature of the vibratory signal.

During a step T2, the determined inertial signature SI is compared with at least one SR reference signature stored by the second communicating object or an associated module. This reference signature SR is representative of the pairing code expected by the second communicating object or its associated module to allow a pairing request issued by vibration from a first communicating object. Advantageously, this comparison uses a technique for mapping the inertial signature SI with at least one reference signature. For example, a distance evaluation based on a dynamic time warping algorithm ("Distance Time Warping") makes it possible to calculate an alignment error between two time signals and to make a decision based on the value of the calculated error with respect to a predetermined error threshold. Such a technique is for example described in the document entitled "A comparative study of several dynamic time-warping algorithms for connected word recognition", written by CS Myers and L. R Rabiner and published in The Bell System Technical Journal, Volume 60 (7). ), pages 1389-1409, in September 1981.

In T3, a decision relating to the correspondence between the inertial signature SI and at least one reference signature is taken. If positive, the pairing request is allowed in T4. If it is negative, the pairing request is rejected in T5. Following the pairing authorization issued in T4, a short-range wireless communication link, for example of WI-FI or Zigbee type can be established between the first and the second communicating objects. With the invention, access to the second communicating object is therefore both simplified and secure. In relation to FIG. 5, the simplified structures of a pairing request device 100 of a first communicating object OC1 with a second communicating object OC2 and a device 200 for processing such a request are now considered. pairing according to an exemplary embodiment of the invention. The pairing request device 100 implements the pairing request method according to the invention as described above. The device for processing a pairing request 200 implements the method for processing a pairing request according to the invention as described above. For example, the device 100 comprises a processing unit 110. equipped, for example, with a processor P1, and driven by a computer program Pg, 120, stored in a memory 130 and implementing the pairing request method according to the invention. At initialization, the code instructions of the computer program Pg, 120 are for example loaded into a RAM before being executed by the processor of the processing unit 110. The processor of the processing unit 110 implements the steps of the pairing request method described above, according to the instructions of the computer program 120. The device 100 comprises a SND unit for transmitting a pairing request in the form of a vibratory signal MV predetermined. According to the invention, the pairing request device 100 is thus arranged to cooperate with a vibratory module MV, and in particular the unit SND is able to control the transmission of the vibratory signal SV. These units are driven by the processor P1 of the processing unit 110.

Advantageously, the characteristics of the vibratory signal SV are stored in a memory in association with a predetermined AC pairing code, for example the memory 130 of the pairing request device according to the invention. On command of the device 100, the vibratory module MV is able to emit the vibratory signal associated with the predetermined pairing code CA.

According to one embodiment of the invention, the first communicating object 001 is an intelligent end terminal user terminal UE1, which conventionally integrates such a vibratory module MV and which furthermore comprises the pairing request device 100. According to another embodiment, the vibratory module is included in an independent MDA pairing module, connected to the first communicating object 001. Such a module further comprises the pairing request device 100 according to the invention. The MDA module in question is placed in physical contact with at least a part of the surface of the second communicating object 002, in order to transmit to it by contact a vibratory signal SV representative of a predetermined CA pairing code. For example, the device 200 comprises a processing unit 210, equipped for example with a processor P2, and driven by a computer program Pg2 220, stored in a memory 230 and implementing the method of processing a request. pairing according to the invention. At initialization, the code instructions of the computer program Pg2 220 are for example loaded into a RAM before being executed by the processor of the processing unit 210. The processor P2 of the processing unit 210 implements the steps of the pairing request method described above, according to the instructions of the computer program 220.

According to the invention, the processing device 200 comprises a unit DET for determining an inertial signature of a vibratory signal SV detected by an inertial navigation module MNI, a comparison unit CMP of the signature determined with a reference signature. and, an activation ACT unit able to activate the requested pairing, in case of correspondence between the determined signature and the reference signature. These units are driven by the processor P2 of the processing unit 210. The unit DET is arranged to cooperate with an inertial navigation module MNI, and in particular to control it the determination of the inertial signature SI of a vibratory signal SV received from the first communicating object 001. The device 200 further comprises a unit for comparing the inertial signature SI determined with at least one SR reference inertial signature stored locally, for example in the memory 230. It also comprises a decision unit. to decide whether there is a match between the IF inertial signature and said at least one reference signature and finally a unit to allow the requested pairing or reject it depending on the decision. Advantageously, the characteristics of the reference signature are stored in a memory in association with a predetermined AC pairing code, for example the memory 130 of the pairing request device according to the invention. According to one embodiment of the invention, the second communicating object 002 is an intelligent end terminal user terminal UE1, which conventionally integrates an inertial navigation module MNI and which furthermore comprises a device 200 for processing a signal. a pairing request according to the invention. According to another embodiment of the invention, the MNI inertial navigation module is included in a processing module of an independent MTA pairing request connected to the second object. Such a module further comprises the device 200 for processing a pairing request according to the invention. Of course, according to this mode, it is the surface of the MTA processing module that must be placed in physical contact with the first communicating object 001 or its associated MDA pairing request module. In connection with FIGS. 6a, 6b, 7a and 7b, two examples of vibratory signals SV and their associated inertial signatures are now presented. In the example of FIG. 6a, the vibratory signal SV1 is a sinusoid of frequency 177 Hz. Its associated SI1 inertial signature is presented in FIG. 6b. If we now consider the example of FIG. 7a, the vibratory signal SV2 is a sinusoid of frequency 183 Hz. At first glance, SV2 looks very similar to SV1. In relation to FIG. 7b, however, it can be seen that its associated inertial signature is very different from the inertial signature SI1 associated with the vibratory signal SV1 of FIG. 6a. The illustrative examples that have just been presented are very simple and intended to highlight the fact that a vibration signal is associated with a unique inertial signature.

They correspond to a first embodiment of the invention, according to which the vibratory signal considered comprises a predetermined frequency waveform. Such a vibratory signal is therefore associated with a fixed pairing code. This association must be known in advance of the first and second communicating objects.

With reference to FIG. 8, a pairing code consisting of a sequence of hexadecimal characters, such as for example a W EP or WPA key and a vibratory signal SV3 according to a second embodiment of the invention, is now considered. . The signal SV3 comprises a sequence of predetermined respective frequency waveforms, a predetermined frequency waveform being associated with a predetermined hexadecimal character. The vibratory signal can thus be constructed by simple concatenation of predetermined unitary waveforms, which is used as the letters of an alphabet to form a word. In the example of FIG. 8, the vibratory signal SV3 is composed of a concatenation of three unitary vibratory signals, the first sinusoidal waveform SV3.1, the second square waveform SV3, and the second one. third SV3,3 triangular waveform. As mentioned above, it is advantageous to associate a hexadecimal character with each unit vibratory signal, so as to form a vibratory signal carrying a sequence of hexadecimal characters. In view of what has just been described, the invention makes it possible to pair two communicating objects simply, just by contact. It therefore contributes to simplifying the use of communicating objects for users both in their home and professional environment. Some examples of exemplary uses cases will now be presented: Pairing a mobile terminal with a residential gateway for a visually impaired person: We consider a visually impaired user who has just purchased a new smart mobile terminal. This terminal includes wireless communication means, for example Wi-Fi. Back home, the user wants to connect the latter to its residential gateway via a wireless link. He launches a touch-peering application on his phone, which vibrates, then places it on a surface of his residential gateway. It is assumed that this application was installed at the time of purchase and that the mobile operator knows the communicating objects of his client and their respective pairing codes. Instead of pressing a pairing button on the residential gateway to activate the entry of a WEP key type pairing code, the user presses a new button on his home gateway to trigger the inertial analysis of the home gateway. specific vibratory signal emitted by the phone. The analysis of the vibration allows the identification of the user and activates the pairing between the two objects. For this visually impaired user, this pairing is simplified because it does not require code entry or clash of terminals.

Exchange of business cards: In this example, two users with their respective smart terminals want to exchange their business card. The first launches a pairing application according to the invention on its smart mobile terminal, which triggers the transmission by this terminal of a specific vibration. He immediately puts his smart mobile terminal on the second user's terminal. The second user launches an application for processing a pairing request on his smart mobile terminal, which triggers the analysis of the vibration received by the latter. If the pairing code received by vibration is recognized as compliant, the second terminal allows pairing and both terminals can establish a wireless communication link to exchange their business card. Payment Security Complement: To identify themselves on a cash dispenser, a user uses a 4-digit code. It is assumed that the user has previously associated with his 4-digit code a vibratory signal selected from a list of vibratory signals made available by his bank and that he has an intelligent mobile terminal equipped with a request device. pairing according to the invention.

An application of the invention consists in connecting a specific module for processing a pairing request to the distributor, so that the user can put his intelligent mobile terminal into physical contact, after having launched the application of vibration pairing application according to the invention.

This specific processing module according to the invention is able to allow the pairing of the distributor with the intelligent mobile terminal, if the vibration it receives corresponds to the pairing code that it expects for this user. In this case of use, the fact of obtaining a pairing authorization is a necessary and additional condition to this of entering a correct identifier code for the distributor to issue the amount of money requested by the user. The invention therefore provides an additional security step, because the user is the only one to know this association between the vibrations issued and the validation of his banking transactions. Similarly, the invention could provide an additional security step to contactless payment solutions based on the NFC (Near Field Communication) technology, the addition of a validation step before transaction by a contact of short duration and vibration exchange allowing the user to confirm his exchange of information.

Of course, other embodiments than the examples described can be envisaged. The invention, which has just been described, therefore potentially applies to numerous applications using all types of communicating objects, as well as mobile terminals of conventional users as connected home devices. It facilitates the pairing between two communicating objects of a user while preserving the aspects related to security.
