METHOD FOR ESTABLISHING A USER DATABASE.

FR 3 054 350 - A1 (£ /) The invention relates to a method of constituting a database (100) of users of mobile telecommunications terminals. It includes the following steps:

- first user data are transmitted by means of a first program of an email intended for the user;

- transmitting first data (23) from the terminal, the terminal data (23) forming a first set (23);

- Each first user data item (22) is associated with the first set (23);

- transmitting second user data (71) by means of a second program of an application consulted by the user;

- transmitting second terminal data (72), the terminal data (72) forming a second set (72);

- each second user data (71) is associated with the second set (72)

- A comparator (98) compares the first and second sets (23, 72).

-1 The invention relates to the dissemination of advertisements on mobile terminals.

It is known to collect remote data relating to Internet users in order to subsequently send them advertising or commercial messages. So, when a user uses a PC-type desktop computer, we know how to associate this user with a consumer profile and their email address. When the user browses a website via his PC, all his actions can be recorded via the site, for example using protocols using "cookies", so as to create and then enrich his user profile. Thus, the affinities of the Internet user and their consumption habits are known. In this way, the user can be restarted at any time by email, with a message designed according to their user profile. It can be a customer who has left a site without validating the purchase of a product for which he has shown interest, which we relaunch by praising the merits of this product. It can also be to make visible to the user on the site advertisements in connection with his past actions, when he visits the site again.

Targeting a particular consumer based on their past habits, particularly a customer who left without consuming, is called "retargeting". If “retargeting” on PC, using web browsers, is a known process, retargeting in the context of mobile applications poses much more difficulties.

Indeed, to broadcast targeted advertising on a user's mobile terminal via a mobile application (and not via a web browser), it is necessary to know the advertising identifier of the terminal, i.e. its "Advertise ID". In order for the advertising content to be relevant, it is necessary to know the past actions of the terminal user and to link them to the Advertise ID. But it can also be very interesting to know his email address, as well as his geographic position so that he can send him the right message at the right time, through the right channel. However, today, in the context of mobile applications, there is no solution allowing to simply trace such data by associating them with each other. In other words, the only solution to associate the Advertise ID, email address and consumption habits with the same user profile is to manually search for data from different databases. It is a long and complicated job, while it can often be interesting to restart a hot user, that is to say shortly after his visit.

An object of the invention is to allow the feedback of relevant data from a user of a mobile terminal in order to target him. The invention thus aims to allow the constitution of a database of this type of user.

To this end, there is provided according to the invention a method of constituting a database of users of mobile telecommunications terminals, characterized in that

- 2 that it includes the following stages:

- when a user consults an email by means of a mobile telecommunications terminal, a first program of the email commands the terminal to send at least one first user data item relating to the user on a telecommunications network;

a processing device external to the terminal obtains at least one first terminal data item relating to the terminal, the terminal data or data forming a first set;

- the or each first user data item is associated with the first set;

- when the user accesses by means of the terminal an application associated with the email, a second program of the application commands the terminal to send at least one second user data item relating to the user on a network of telecommunications;

the processing device obtains at least a second terminal data item relating to the terminal, the second terminal data or items forming a second set;

- the or each second user data item is associated with the second set;

- a comparator compares the first and second sets; and

- if the first set is identical to the second set, a processing device associates the or each first user data item associated with the first set with the or each second user data item associated with the second set, within a profile of user.

The first user data, in particular the email address, are known to user databases, but unknown to the publisher of the application or site. This is why when the email, which is preferably informative, is sent to the user, the program present on the email, which can be called "tag >> or" pixel ", sends this or these first data of user, which it contains, to a processing device. On the other hand, the program cannot of course access certain data: it does not make it possible to know the user's "AD ID", it does not make it possible to retrieve user consumption information. This is why a processing device requests to obtain the first terminal data or data which will make it possible to characterize the terminal. This first set of first terminal data thus forms a signature, or even a fingerprint, of the terminal. In other words, the device calculates a fingerprint of the terminal.

In the second step, another program, tag or pixel, present on the application, allows it to retrieve the Advertise ID. However, this second program does not allow to know the email address of the mobile user. That is why

The device again requests to obtain terminal data, called second terminal data, forming the second set. So it's a matter of calculating a footprint of the terminal, again.

To associate the first user data, returned by the first email program, with the second user data, returned by the second program, the two sets of terminal data are compared. If they are identical, this means that the terminal used is the same. We can then associate, for example, the email address with the user's Advertise ID. It is then possible to target this user by sending him emails and by making advertisements appear on the application.

Thus, the invention makes it possible to simply gather relevant data relating to a user in order to be able to restart it.

Preferably, the first user data (s) include an email address of the user, in particular in encrypted form.

Advantageously, the second user data or data comprise an identifier of the terminal associated with advertising functions.

This identifier is generally called “Advertise ID”, each terminal manufacturer however having its own name.

Preferably, the terminal data or data comprise at least one of the following terminal data:

- a version of the terminal operating system;

- a terminal geolocation address;

- an IP address of the terminal;

- a mark of manufacturer or seller of the terminal;

- a screen resolution of the terminal; and

- a terminal serial identifier.

These data form the first and second sets which are sent in two stages from the terminal. They form "fingerprints" or "signatures" of the terminal. These data thus make it possible to characterize a terminal, and therefore, when a first set is identical to a second set, to associate all the data which are already associated with these respective sets, such as the email address on the one hand and the Advertise ID on the other hand.

Advantageously:

- After the implementation of the preceding steps, when the user consults the application by means of the terminal, software for tracing the application obtains at least a third user data item relating to the user;

- the software controls the sending by the terminal of the or each third data

-4 user on a telecommunications network; and

- the processing device associates the or each third user data item with the user profile.

Thus, each time the user browses the application again, his actions are known and recorded. They allow you to enrich your user profile and therefore to get to know the user better in order, for example, to present him with future advertisements in line with his profile. The more his profile is known and enriched, the more relevant the messages that will be sent to him or that will be made visible to him.

Preferably, the third user data includes at least one of the following data:

- user geolocation data;

- data relating to a user action on the application;

- data relating to a history of the user's journey on the application;

- data relating to the user's purchase history on the application;

- data relating to the user's intention to purchase; and

- data relating to user affinities.

Advantageously, a second email is prepared taking into account at least one of the user data and the second email is sent to the user.

So the second email is relevant because it targets the user based on what is known to them. It is therefore intended to be more effective than an impersonal document. It is specified here that if this second email is prepared taking into account at least one of the second user data, it is not necessary that it incorporate such data. Indeed, it can understand information resulting from this data and not understand the data itself.

Preferably, the second email includes at least one of the user data obtained during the previous steps.

For example, it may be to address the user using their first and last name.

Preferably, when a device detects that the user is performing a predetermined action, the display, broadcasting or sending of a message on the terminal is controlled via a telecommunications network.

Advantageously, the predetermined action includes the arrival of the terminal in a predetermined geographic area, in particular an area associated with a datum of the user's profile, for example relating to a point of sale.

For example, if it is known, in view of its actions on the application, that the user likes a certain type of product, it may be worth sending him an email

-5when approaching a point of sale for this type of product.

Preferably:

a processing device obtains at least a fourth user data item by means of a terminal via a local telecommunication network, for example of the "Bluetooth" type, and orders its sending over a telecommunication network; and

- the processing device associates the or each fourth user data item with the user profile.

Thus, for example in a store, when a user has switched on the "bluetooth" mode of his terminal and that he is configured to send information, his passage near a terminal can allow the latter to recover one or more user data and enrich the user profile.

Advantageously:

- a processing device determines at least a fifth user data relating to the user from the user data already obtained; and

- the processing device associates this or every fifth data item with the user profile.

For example, some of the known user data may relate to the sex, age, profession and affinities of the user. It is then possible to determine other data which would relate to the user's propensity to be interested in a future product, or in a product which he has not hitherto considered. This data would depend on the aforementioned data, and therefore would not have been reassembled, but would be deduced by the processing device from user data already known. It would then be relevant to advertise this product to this user.

The invention also provides a method of constituting a database of users of mobile telecommunication terminals, in which, when a user accesses by means of a mobile telecommunication terminal and via e-mail an application associated with email:

- an application program obtains at least a first user data item relating to the user and at least a second user data item relating to the user;

- the program orders the sending by the terminal of or each first and second data on a telecommunications network, and

- a processing device associates the or each first datum with the or each second datum within a user profile.

This is actually the special case where the user already owns the application, or is redirected by email to the application. In this case, there is no need to

-6reassemble terminal data because there is no need to compare this data. Indeed, the program, or tag, or pixel, goes up by itself the first and second user data.

According to the invention, a method of digital prospecting of users of mobile telecommunications terminals is also provided, which comprises at least once all of the following steps:

- putting an application for a mobile terminal online on a telecommunications network, the application comprising tracking software capable of obtaining user data when it is used on a mobile terminal, and

- sending over an telecommunications network of an email associated with the application and comprising a program capable of containing user data when it is used on a mobile terminal.

According to the invention, a method is also provided for constituting a database of users of mobile telecommunication terminals, which comprises the following steps:

- when a user consults an email by means of a mobile telecommunications terminal, a first program of the email commands the sending of at least one first user data item on a telecommunications network;

- when the terminal receives a first request from a processing device external to the terminal in order to obtain first terminal data relating to the terminal, the terminal sends at least one first terminal data;

- when the user accesses by means of the terminal an application associated with the email, a second program of the application obtains at least a second user data and orders the sending of the or each second user data; and

- when the terminal receives a second request from the processing device external to the terminal in order to obtain second terminal data relating to the terminal, the terminal sends at least one second terminal data.

According to the invention, a mobile telecommunication terminal is also provided, making it possible to navigate on a mobile application and arranged to implement the above method.

Preferably, in all the aforementioned processes, the email is sent to the user before the steps set out.

It can be expected that this email is not prepared by the publisher but by a trusted third party who integrates the program containing the user's email address, unknown to the publisher, in the email.

There is also provided according to the invention a method for comparing sets of

-7data from mobile telecommunication terminals, in which automated means control the following steps:

- sending to a processing device a first set of terminal data relating to a mobile telecommunication terminal;

- sending a second set of terminal data relating to the terminal to a processing device;

- association of the data of the first set with each other so as to form a first character string;

- association of the data of the second set with each other so as to form a second character string;

- comparison of the first and second channels:

- if the strings are identical, execution of a predetermined action relating to a user profile.

Thus, if all the characters are identical, it is considered that the first and second sets of data relate to the same mobile terminal, otherwise it is considered that the first and second sets relate to different mobile terminals. If only one piece of data is different, the two sets of terminal data are considered to come from different terminals respectively.

Advantageously, the predetermined action comprises a step of association of the first and second sets and of user data associated respectively with the first and second sets, within a database so as to create or enrich a profile of user.

A computer program is also provided according to the invention, comprising code instructions capable of controlling the implementation of the steps of a method according to the invention when it is executed on a computer.

According to the invention, there is also provided a method of making the program according to the invention available for downloading on a telecommunications network.

According to the invention, a system is also provided for constituting a database of users of mobile telecommunications terminals, which comprises:

a device capable of generating an email arranged so that, when a user consults the email by means of a terminal, a first program of the email commands the terminal to send at least one first relative user data item to the user on a telecommunications network;

- a processing device capable of obtaining at least one first terminal data item relating to the terminal, the first terminal data or items forming a first set, as well as at least one second terminal data item relating to the

-8terminal, the second terminal data or data forming a second set;

- means capable of associating the or each first user data item with the first set;

an application associated with the e-mail and arranged so that, when the user accesses the application by means of the terminal, a second program of the application commands the sending of at least a second user data item relating to the 'user;

- means capable of associating the or each second user data item with the second set; and

a processing device arranged so that, if the first set is identical to the second set, the processing device associates the or each first user data item associated with the first set with the or each second user data item associated with the second set , within a user profile.

There is also provision for a database resulting from the implementation of a method according to the invention and comprising an electronic recording medium comprising in recorded form at least one item of the following data:

- data relating to a user action on a mobile application;

- data relating to a history of a user's journey on a mobile application;

- data relating to a user's purchase history on an application;

- data relating to a user's purchase intention;

- data relating to a user's affinities;

- civility data of a user;

- a user's address;

- a screen size of a terminal; and

- data of socio-professional category of a user.

We will now present embodiments of the invention with the support of the appended figures, which are provided by way of examples and have no limiting character, in which:

- Figure 1 illustrates a method of constituting a database of users of mobile telecommunication terminals according to a first embodiment of the invention;

- Figure 2 illustrates a method of comparing sets of mobile terminal data according to an embodiment of the invention;

- Figures 3 to 5 illustrate the possibilities of collecting user data according to modes of implementation of the invention which can be combined; and

- Figure 6 illustrates a method of constituting a user database

-9mobile telecommunication terminals according to a second embodiment of the invention.

In the following, even if it is not specified, it is assumed that the different elements implementing the method of the invention (terminals, devices, database, etc.) communicate with each other when necessary on a or several wireless telecommunications networks such as a mobile telephone network, a Wi-fi network or even bluetooth. Furthermore, all of these elements are equipped with at least one processor and at least one memory and capable of controlling and / or implementing the operations which concern them in the following when a suitable computer program is implemented implemented in these elements. Provision is also made for making such programs available on a telecommunications network for downloading.

First embodiment

In the examples which follow, the invention is used by two types of actors.

First there are the publishers, that is to say the mobile application managers concerned with the invention. They want to be able to target consumers who have used their apps. They want to be able to relaunch them with relevant advertisements, because they are in line with the interests of each consumer.

The other players are the consumers. In the remainder of the request, they will be called users or mobile users (for mobile terminal users). Individuals download and use mobile apps from publishers. After browsing these applications, they will receive from publishers personalized information, advertisements, by email or via advertising spaces placed on these applications.

The invention works in two stages. The first is to collect user data. The next step is to use that data to send the right message in the right way at the right time through the right channel.

Collection of data

We will first describe, with reference to FIG. 1, a method of collecting data, that is to say of constituting a database of users of mobile telecommunications terminals.

In the following, we will speak of an editor as being responsible for the mobile application, and of a user as being the person who uses it, in accordance with

- 10 previous definitions.

Different elements are to be identified for a good understanding of the invention:

- the mobile application 2, illustrated in FIG. 1, designed by the publisher, is in the following example an m-commerce application, that is to say that it allows the user to obtain information on products and possibly buy them directly via the app.

- the mobile terminal 3 of the user 1 does not include at the start of the process the mobile application 2 of the publisher, and is a smartphone. It could be a tablet or another type of mobile communication terminal on a wireless telecommunication network such as a mobile phone network, a Wi-Fi network or even Bluetooth.

- the informative email 11 relates to the mobile application 2, that is to say that its content advertises this application or deals with a subject associated with the application. At the start of the process, it is present in a database 12 connected to a processing device 14, in the form of an email to be sent.

This collection process is itself divided into two stages. First of all, it involves bringing up the first user data, associated with a set of data characterizing the mobile terminal of each of them.

A first step 10 comprises sending the informative email 11 to a user, by a processing device such as a server 14. The sending is done via the internet, like all the exchanges described below between the mobile terminal and the various treatment devices. User 1 is not known to the publisher. This is an individual who has previously given his consent for his email address to be recorded in a database 12. In this database, users are classified according to different criteria, such as their socio-professional category, their age and their gender. Thus, the publisher can request that the email be sent to all mobile users who meet certain criteria. However, he does not know their personal data.

Email 11, which can also be called "newsletter", is written in html format and is "responsive design", that is to say that it is suitable for reading on a mobile telecommunications terminal, such as a smartphone or tablet and is designed to adapt its display to the format and dimensions of the terminal screen. It includes images, links and / or text, which may recall the graphic charter of the publisher, that is to say that of the mobile application.

This informative email includes a link to Application 2, which redirects to a download page if Application 2 is not already registered on the device.

It also includes a program 13. We can call this program “tag”,

- 11 or "pixel". This program contains first data 22 concerning the user and code instructions, which, when the email is opened by the mobile terminal of the user, control in step 20 the sending of these first data 22 of the user by this terminal and via a telecommunications network to a processing device 21 accessible by the editor. This first user data 22 is in particular the user's email address in encrypted form. This is more specifically the so-called "md5" fingerprint of the user's email address. The data 22 also includes the address of the database, source of this md5, so that it can be found. They also include data on the user's civility, socio-professional category, age, and possibly other data, such as geolocation data. This can include all categories of data in the database.

So when the user reads the email, the md5 fingerprint of their email address becomes known to the publisher. By a conventional web service system well known to those skilled in the art, the e-mail address itself is found from the md5 of this address. However, it cannot be used until it is associated with a particular user, i.e. with a user profile. Indeed, it is relevant to send information to the email address of a user whose consumption habits are known, for example, and who is well identified. This is the main objective of the invention.

To do this, in step 30, the processing device 21 sends a request over the network in order to obtain data 23 relating to the user's terminal. It is a web request requesting easily accessible data.

This data 23 is sent to the device by the terminal in step 40 over the network. These data 23 must make it possible to characterize the mobile terminal, so that if the same data are found later, we know that they come from the same mobile terminal, and therefore from the same user. This data 23 therefore forms a set of terminal data. We can also say that it is a signature of the terminal or a fingerprint of the terminal. This data 23 is in particular the version of the operating system of the terminal, a geolocated address of the terminal, an IP address of the terminal, a brand of manufacturer or seller of the terminal, a screen resolution of the terminal, or even an identifier of terminal series. In other words, it can be said that during this step 40, the processing device 21 calculates a fingerprint of the terminal 3. In total, this fingerprint formed by first terminal data can be composed of about twenty data.

Then, during step 50, the device 21 associates this first data of terminal 23 with the first data 22 of the user, in particular the email address

- 12 now decrypted, within a database 24. From now on, what is known to the user by the editor are his first user data 22, notably his email address, and first terminal data 23 characterizing his mobile terminal, which can be called the terminal fingerprint.

If user 1 never downloads the mobile app 2 from the publisher, that data 22 and 23 is irrelevant. However, he is encouraged by the informative email 11, via the link for this purpose, to download the application 2, which he does in step 60. Thus, if in a second step the user downloads and browses mobile application 2, then the method according to the invention takes on its full meaning.

Indeed, the invention provides that a second program 62, or tag, or pixel, is located on the mobile application 2. Unlike the first program 13 present on the informative email, this program 62 does not contain the email address of the user. However, it makes it possible to obtain second user data 71, in particular the advertising identifier of the terminal, otherwise called “Advertise ID”, and to order its sending by the terminal to a processing device 73. It also contains other second user data, such as a geolocated location. In step 80, the processing device 73 sends a request over the network in order to obtain second terminal data 72 relating to the user's terminal. It is a web request requesting easily accessible data. This data 72 is sent to the device by the terminal in step 90 over the network. These data 72 must make it possible to characterize the mobile terminal. Again, this is a fingerprint of the terminal. These second terminal data 72 are therefore in this case the version of the operating system of the terminal, a geolocated address of the terminal, an IP address of the terminal, a mark of manufacturer or seller of the terminal, a screen resolution of the terminal, or a terminal serial identifier. In other words, it can be said that, during this step 90, the processing device 73 calculates a second imprint of the terminal 3.

The second user data 71 and the second terminal data 72 are associated with each other by the processing device 73 in the database 74 during step 95. In the database 74, the second set 72 terminal data is therefore associated with second user data 71, such as "the Adviseise ID". This “Advertise ID” is an important piece of information: this identifier makes it possible to send advertisements directly to the screen of the user's mobile terminal, in advertising spaces provided for this purpose on the publisher's mobile application, for example . However, in this database 74, we do not know his email address. We do not know his civility data, his socio-professional category or his age.

- 13Let's recap where we are. At this moment, the data of user 1 is distributed in two places:

- in the database 24 appear its data of civilities, its email address, its socio-professional category. These are the first user data 22. They are associated with a first set 23 of data from its terminal.

- in database 74 are its advertise ID, as well as other user data. They form second user data 71. They are associated with the second set 72 of terminal data.

Since the invention performs these steps for many users, two separate databases 24 and 74 are obtained comprising first user data associated with first sets for one, and second user data associated with second sets for each other. However, the objective is to be able to gather this data within user profiles, in order to determine for the same user his email address and his advertise ID, with other user data transmitted by the "pixels", or programs, 13 and 62.

To allow this regrouping, it is necessary to compare two by two the first and second sets of terminal data 23 and 72 of the respective databases 24 and 74.

Thus, if a first set is identical to a second set, we know that these sets come from the same terminal and that therefore the first and second user data to which these first and second sets are respectively associated correspond to the same user.

We will therefore describe, with reference to FIG. 2, a method of comparing sets of data from mobile terminals. This is an example showing terminal data different from the data 23 and 72 in FIG. 1, but with the same comparator 98 and the same databases 24 and 74.

The comparator 98 obtains from the database 24 one of the first sets 96, and from the database 74 one of the second sets 97.

These sets 96 and 97 are then written in the form of character strings. Thus, each character string includes all the data of the set in question joined end to end following each other in a predetermined order.

The comparator compares the two strings character by character. Thus, the first characters 93 and 94 respectively of each set are compared. If they are identical, the comparator compares the following characters, and so on.

If the comparator determines that certain respective characters of the two sets

- 14 are not identical, as is the case with characters 91 and 92 of FIG. 2, it stops the comparison and sends as a result to a processing device 99 that the terminals from which these sets 96 and 97 originate are not the same terminal. The comparator then proceeds to the next comparison, consisting in comparing the first set considered this time with the next second set in the base 74.

On the other hand, if, as in FIG. 1, the comparator 98 determines that the first and second sets 23 and 72 are identical, this means that the terminal data of each set comes from the same terminal 3.

The processing device 99 then associates the data associated with each set in step 130. In particular, the email address associated with the first set 23 is associated with the Advertise ID associated with the second set 72. The first and second data of the user 22 and 71 are therefore known, associated with one another and enrich a user profile 91 in a database 100.

The comparator thus performs a reconciliation of the two databases to determine which are the first and second sets which correspond to the same terminal and thus constitute exploitable user profiles. As a reminder, in these terminal footprints there is in particular a geolocation datum. A terminal which would have changed position between the sending of the first and second terminal fingerprints would therefore not allow the reconciliation between the first and second user data. This geolocation data is however necessary to limit the number of fingerprints to be compared, for example by comparing fingerprints whose geolocation data are identical, so as to obtain rapid positive results and to create user profiles quickly.

The first phase of the invention is therefore complete: the publisher knows relevant information about user 1 and has the means to contact him, by email via his email address or by broadcasting advertising via the Advertise ID. Subsequently, this profile 91 will therefore make it possible to recontact user 1, using the data recorded there. This profile will also be enriched thanks to tracking software 61 which is present on the mobile application 2 and which continues to obtain user data when the user 1 browses on the application 2.

Tracing software

Indeed, a tracking software 61 of the application makes it possible to carry out the following actions:

- record any activity by user 1 on the publisher's mobile application 2 and

- 15 order information to be sent via the terminal about this activity;

- obtain other user data such as the geographic position of the terminal, if the geolocation of this terminal is planned and granted by the user, and order its dispatch.

Software 61 can optionally perform other types of actions, obtain other data, and send it over the network.

Thus, each time the user navigates to the application 2, data can be deduced from his actions and sent by the terminal to a processing device.

Sending targeted messages

With reference to FIGS. 3 and 4, we will describe the second step of the invention, which consists in implementing “retargeting” or retargeting operations, that is to say relaunching the user so relevant by means of the invention.

FIG. 3 thus illustrates a relaunch by a new email 105, or newsletter. This is a method called "email retargeting".

In step 101, the user navigates to the mobile application and therefore performs actions which give rise to new user data 102 which are obtained by the tracking software 61. This is for example a looking for a particular product. These new user data 102 can be sent by the terminal to the processing device 99 on the network each time they are obtained, at predetermined time intervals, or even when specific actions have been performed by the user. 1, for example when it validates a shopping cart for products on the application 2.

At a predetermined time, the processing device 99 having received this new user data 102 prepares in step 111 a new informative email 105.

Unlike the first informative email 11, sent impersonally to user 1 in step 10, this new email 105 is designed by the processing device 99 to be personalized. To this end, the device 99 uses the user data collected and stored in the database 100 in the user profile 91: the first and second data 22 and 71 respectively, but also the new user data 102 which have been provided. For example, email 105 can be in the name of user 1 and deal with a product that he particularly appreciated since he had placed it in his shopping cart on the mobile application 2, before finally do not settle the payment and confirm the purchase. This email 105 can also inform the user that the product is visible in a

- 16 point of sale near him. Thus, all the user data which will have been obtained by the tracking software 61 then makes it possible to send the user 1 a relevant email 105.

The timing of sending this email 105 in step 121 is also important. As will be seen below, a set of parameters dealing with email 105 and its sending can be provided by the publisher. For example, it may be appropriate to send email 105 within one minute of the end of the user's visit to the application, or to wait a few hours. This sending is carried out automatically by the processing device 99, but it can of course be decided manually.

Finally, unlike the first informative email 11 which was sent to user 1 and to application 2, this email 105 does not have a program reporting the first user data. The first user data 22 is already known at this stage. Besides, there is no need to wait for user 1 to navigate several times to application 2 before relaunching it. As soon as its first and second user data 22 and 71 respectively have been associated with each other, it can be restarted.

Referring to Figure 4, we will describe another retargeting method: "display retargeting" or retargeting by display. This time, it's about using user data to display relevant advertising on the screen of their mobile terminal, at a relevant time. In the example illustrated, in step 201, the tracking software 61 sends by means of the terminal on the network the geolocated position 202 of the user 1 to the processing device 99. The latter determines that the user 1 is located near a point of sale in which there is a product for which the user has shown interest via the application. In response, the processing device 99 commands the sending at step 211 of an advertisement 212 on the mobile terminal 3 of the user 1, this advertisement 212 informing the user 1 that a point of sale for a product that interests him is close to him.

This detection of the user's geographic position could be triggered by the application itself, which then sends an alert to the processing device so that an advertisement is prepared and sent. Advertising can be disseminated by knowing the Advertise ID of user 1, which is always stored in user profile 91 in the database 100. This advertisement 212 is displayed on the application mobile 2, for example in a space provided for this purpose. It is also possible that, since the application 2 has not been closed by the user 1 while the latter is browsing another application, on the internet or simply on a menu on his terminal 3, the advertisement 212 is displayed on its screen, leaving for example the possibility for user 1 to close it after a predetermined duration. Advertisement 212 is a

- 17 picture. But it can be any other type of content, such as video, audio, or interactive content asking the user to act.

The user data 22, 71, 102, 202 thus make it possible to relaunch the user by means of relevant emails or advertisements, sent at key moments with information linked to the profile of the user 1. As a reminder, the first user data 22, in particular his e-mail address, were obtained before user 1 had the application 2, via the program 13 of the e-mail 11. The second user data 71, in particular the Advertise ID, were obtained via program 62 of application 2. Since his user profile 91 was created, each time user 1 browses application 2, new user data is retrieved and sent by the tracking software 61 to the device 99 and to the database 100.

But this data is not used only in a raw way. They can indeed be analyzed in order to determine other data. For example, when the user does not validate the purchase of a product, the data brought to the processing device will be linked to this product. The device can deduce from this data that the user could be interested in other similar products, such as those belonging to the same range. By crossing several data, he may be led to determine that a particular product, for which the user has not shown interest, could in fact interest him. Thus, the user data obtained makes it possible to deduce others, and thus to send e-mails or to broadcast relevant advertisements.

FIG. 5 illustrates a method of collecting data for a user 5 passing through a point of sale. Thus, by means of a terminal 311 communicating according to the "bluetooth" protocol, user data 302 can be collected by terminal 311 and sent over the network. If user 5 already corresponds to a user profile, this data 302 can thus complement it. In addition, this type of terminal allows brands to analyze and measure the frequency of consumer visits to the point of sale. By associating this data 302 with the user data returned by the tracking software, the user profiles are enriched. For this communication via Bluetooth to work, user 5 must not have deactivated it and must have given its consent to supply data 302.

On the publisher side, the invention provides a platform for setting up and configuring recovery campaigns. Thus, an editor can choose a geographic area, a start date and an end date for his campaign. The invention will therefore operate within the chosen interval and for mobile terminals located in the chosen geographical area. The platform also makes it possible to load the advertisements that the publisher wishes to broadcast, to adjust parameters concerning the emails of

- 18 reminders that will be sent, such as the time interval between the user's last visit to the application and sending an email, the type of subject that should be contained in emails, etc.

This platform could also be used by another type of actor: advertisers. Indeed, it is possible that publishers and advertisers may use the invention separately. In this way, the publisher would use user data to allow advertisers to send emails or broadcast relevant advertisements on the mobile application, without these advertisements being necessarily linked to the application. The publisher can thus sell user data and / or advertising space to advertisers to enable them to carry out relevant targeting. In this case it is possible that the process is not "retargeting", but "targeting", that is to say simply sending emails or advertisements to users who would not have previously contacted the advertiser . In this case, the first informative email received does not relate to the advertiser. It can be relative to the publisher.

Finally, the invention provides an "SDK". This is the acronym for "Software Development Kit". It is a set of computer programming aid tools. So this is a set for IT developers. This SDK makes it possible to implement the invention on mobile terminals, and to configure it directly by computer programming.

Second embodiment

With reference to FIG. 6, we will now describe a second embodiment of the invention allowing the constitution of a database of users of mobile telecommunication terminals. This embodiment is broadly identical to the first. We will describe in the following only the characteristics which differ from the first mode.

This mode is implemented when the user 6 already has the mobile application 2 before receiving the first informative email 11. It is indeed quite possible that he has already downloaded the application 2 on his own initiative. As a reminder, the informative email 11 includes a link to the application, which redirects to a download page if the application 2 is not already registered on the terminal 3. It also includes a program 13 capable of bringing up the first user data 22 such as the user's email address 6. Likewise, the application includes a program 62 capable of sending up second user data, including the advertise ID.

When he receives the informative email 11 in step 10bis, if the user 6 opens

- 19 the application 2 using the link to this located on the email 11, the program 62 is capable of obtaining itself the data 22 of the program 13 of the email 11. Thus, unlike the first mode of setting implemented, the terminal can send the first data 22 as well as the second user data 71 by means of the program 62. Since these first and second data are retrieved at the same time, they are automatically associated with each other. other. In particular, the AdvertiselD and the email address of the user 6 are associated with the user profile 106 by the device 99 within the base 100, in step 120bis. There is therefore no need to obtain and compare terminal data. Thus, no fingerprint calculation is necessary. However, it is still possible to request this terminal data in order to save a set of data from the terminal in the user profile. Even if this is only of limited interest at the time of registration, this set could subsequently be compared to other sets, for example in the case where the user deleted and then downloaded the application on his mobile terminal.

Of course, many modifications can be made to the invention without departing from the scope thereof.

Thus, the invention is applicable to any type of mobile application, and not only to those of m-commerce.

In addition, all the technical elements described above as being separate can of course be grouped together. Thus, a single processing device can perform the functions of the various processing devices described, just as a single database can gradually group together all the data obtained by means of the invention. Besides, one can imagine that a single database includes several data tables. The invention can work by any telecommunication network, and not only by internet. Part of the data or even all the data can also be stored locally and at least temporarily on the user's mobile terminal, for example in the event of an impossible connection with the telecommunications network.
