Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of billboards, and more particularly the billboards planning permission issued by local authorities. The invention will find for advantageous but non-limiting application the field of billboards for building permits, for prior declaration, for permits to demolish or for permission to develop.

STATE OF THE ART

Building owners who apply for planning permission to carry out their construction projects are generally obliged to inform third parties of the authorization issued to them (usually by the town hall), usually by way of a Billboard with codified regulatory features. In the case of France, this codification is the subject of Article R.424-15 of the French Town Planning Code and associated ministerial orders.

This kind of panel can be easily found in building material stores or be custom made by a printer. The display panel has the following mechanical characteristics in France: • Dimensions: 80cm x 80cm minimum, typically 80cm x 120cm, thickness 3 to 7mm • Material: Polypropylene or PVC extruded plate in plate • Technique for printing information: silkscreen (for large quantities) or ink jet (for small quantities) • Fixing method: typically through eyelets affixed to the four corners + free fixation by the applicant (ropes, wire, ankles ...) on any type of support (eg mesh fence, wall, dedicated plywood or medium support ...) • Customization of the mentions can be done in two ways: o most common case: free spaces are provided so that the applicant can enter by his care (eg indelible marker) the details of its own o rarer print personalized mentions by silkscreen or inkjet printing imeur

This type of panel has many disadvantages. They are for example generally very fragile, a gust of wind or acts of vandalism are enough to tear them off or degrade them.

Then, the display of the panel on the ground causes a delay, which is in France of two months, during which the thirds (for example the neighbors) can bring an action against the owner under their rights civil or against the administrative authority that issued the authorization.

Due to this two-month period of "purge third party recourse" it is desirable for the owner to be evidence of their good faith in the respect of this legal obligation to display.

Depending on the legislation and regulations mentioned above, the display must meet several conditions: • include certain mandatory information; • be visible from the public highway; • be displayed on the edge of the land on which the construction will be built; • remain posted for a continuous period of two months;

In order to address the last point above, it is common for the building owner, particularly with regard to building permit type authorizations, to draw up a report stating the display of the panel by a bailiff of justice. In this case, it is agreed that the bailiff will move instead of displaying the panel three times during these two months of panel display. After each passage, the bailiff drafts a report factually reporting the findings (characteristics of the panel, location, visibility from the public road, etc.). The report may include photographs.

The minutes are sent to the client by post in original paper format or electronically, typically in PDF format (unencrypted, not electronically signed) by e-mail.

However, this type of finding by a bailiff has many disadvantages, from the economic point of view for the client, but also for the legal security vis-à-vis third parties. Indeed, although accepted by the case law, the low number of passages from the bailiff (3 maximum) does not guarantee the continuity of posting on the appeal period of thirds of two months.

The present invention aims to solve at least in part the problems mentioned above.

We will now expose the present invention in various facets through different figures. Example of a Use Case According to an Embodiment of the Present Invention

According to one embodiment, the present invention is addressed to a user, a client for example, wishing to obtain proof of exposure of information to third parties at a lower cost than the report by bailiff for example and wishing to ensure the visibility of said information over time, or even in real time.

Figure 1 shows a scenario of the present invention according to one embodiment. This figure thus represents a house 1 for example being the subject of expansion work planned at the end of the appeal period of third parties and built on a terrain comprising a shaft 3 which is fixed a display panel 20 according to an embodiment of the present invention. The land includes house 1 and is bordered by a low wall 4 separating it from a public road 2.

Preferably, the display panel 20 is arranged in height so as to be visible beyond the wall from the public road 2.

This use case exposes for example a good example of problems that can occur during the exposure of the billboard. For example, it could fall out, fall to the ground upset by the wind, be vandalized or a branch of the tree could fall and obstruct the visibility of information on the billboard. As we will see later, the present invention allows the user to be informed of this type of event even when the user is not on site and thus allows him to intervene.

FIG. 2 represents a display panel 20 according to an embodiment of the present invention, and more particularly the front face of a billboard intended for the display of a building permit. This display panel 20 comprises a front face comprising a plurality of printed inscriptions 21, and a plurality of non-printed areas 22 intended to receive a printed and / or handwritten inscription specific to the user.

The display panel 20 according to one embodiment of the present invention is preferably pre-printed in accordance with the regulatory requirements.

In addition, this display panel 20 is advantageously configured to communicate with a satellite system 10 on the one hand and with at least one computer server 40 on the other hand. For this, and according to a preferred embodiment of the present invention, the display panel 20 comprises an electronic device 200 comprising at least one geolocation module 220, a radiofrequency communication module 230 and a power supply module 203.

Preferably, the power supply module 203 is configured to electrically power the electronic device 200 to advantageously a duration corresponding to the statutory display period, for example 2 months for a building permit.

Fig. 3 is a schematic representation of the data stream according to one embodiment of the present invention. In this figure, geolocation data, preferably encrypted, are transmitted from a satellite system 10 to the display panel 20. The display panel 20 communicates with a computer server 40 via at least one communication network 30 so that the computer server 40 can issue a certificate 50 to the user relative among others to the geographical position of the display panel 20.

According to a preferred embodiment, the display panel 20 is configured, via its geolocation module 220, to obtain geolocation coordinates from satellite systems 10 such as Global Positioning System, Glonass, Galileo for example.

Thus, the display panel 20 according to one embodiment reports its geographical position continuously to a computer server 40 automatically and without any other intervention of the user than to install it at the edge of the ground visibly from the track public 3, as for a traditional panel.

In addition, and in order to guarantee the validity of the data that the display panel 20 receives and transmits, the display panel 20, via its electronic device 200, is configured to secure said data via, for example, an encryption of these data. ci by an encryption key.

According to a preferred embodiment, the transmissions from the display panel 20, via the electronic device 200, to the computer server 40 can be encrypted and authenticated in such a way as to guarantee the confidentiality of the data and their correct and non-falsified attribution to a computer. user whose data associated with the display panel 20 are managed by the computer server 40.

Transmissions from the display panel 20 via the electronic device 200 to the computer server 40 are preferably conducted wirelessly by, for example, radio frequency technologies and communication protocols such as Low Power Wide Area Network (LPWAN). , LoRa, Sigfox, and / or digital cellular technologies and protocols of the SMS (Short Message Service) / GSM (Global System for Mobile) / HSCSD type. "High Speed Circuit Switched Data") / GPRS (English "General Packet Radio Service") / EDGE (English "Enhanced Data Rates for GSM Evolution") / WCDMA (Wideband Code Division Multiple Access ") / HSPA (High Speed Packet Access) / LTE (of the English" Long Term Evolution ") 4G / 5G, etc ..., or more generally any type of technologies and protocols of wireless communication; these technologies and communication protocols are well known to those skilled in the art.

According to an advantageous embodiment, the electronic device 200 tracks the position of the panel 20 continuously while alerting the user in case of anomalies, called "alerts" such as a defect of its physical integrity or events detected by the sensors.

Preferably, this electronic device 200 is designed to transmit data relating to said events and to the physical integrity of the display panel 20, via the use of an integrity module 210 comprising one or more sensors. This integrity module 210 thus allows the present invention, according to a preferred embodiment, to detect and transmit to the computer server 40 events that may compromise the legal validity of the display or the physical integrity of the panel. display 20, for example: laceration or rupture due to wind or vandalism, drop of the display panel or change of its orientation, or even drop of element in front of the display panel 20 reducing its visibility.

Physical integrity issues will be further discussed later.

Advantageously, the electronic device 200 allows the execution of a computer program stored in a non-transitory memory which realizes functions which will be described later, including in particular the regular and automatic transmission of the position of the display panel 20 to which is advantageously allocated a unique identifier to a computer server 40.

Thus, beyond the physical integrity of the display panel 20, the present invention also seeks to ensure the integrity of the execution of the computer program by electronic and software techniques such as "Secure Element" (SE ) or "Trusted Execution Environment" (TEE), well known to those skilled in the art, storing an encryption key for decrypting the computer program before its execution and preventing the execution of an unauthorized modified computer program. Those skilled in the art may refer to many works of the prior art relating to these well-known techniques, including for example: Swaminathan, S.,

Rawat, S., Coogan.G. and Vanderhoof.R., "Mobile / NFC Security Fundamentals -Secure Elements 101", Smart Card Alliance Webinar, March 28, 2013, or A. Vasudevan, E. Owusu, Z. Zhou, J. Newsome, and J.M. McCune. Trustworthy Execution on Mobile Devices: What security properties can my mobile platform give me? In Trust and Trustworthy Computing, vol. 7344 of LNCS, pp. 159-178. Springer, 2012.

The present invention also allows the detection of operating anomalies of the electronic device 200 such as software restarts, a low battery level or an interruption of the power supply, a loss of the geolocation satellite signal or the communication network 30. All of these measures, be it with respect to events that may affect the compliance of the display, physical integrity, software integrity, operating integrity or data encryption, allow the present invention to ensure the validity of the data received at the computer server 40, which generates a certificate 50 to the user.

Thus the present invention allows on the one hand the display of mandatory information in accordance with the law and regulations, pre-printed on the front panel according to conventional printing techniques. According to one embodiment, the display panel 20 may comprise one or more customizable fields displayed digitally, for example using OLED (Organic Light-Emitting Diode) screens, LEDs (of the English "Light-Emitting Diode"), LCD (of the English "Liquid Crystal Display") or e-ink (of the English "Electronic Ink"), etc ..., these digital display devices being well known to those skilled in the art.

On the other hand, the display panel 20, via the electronic device 200 that it comprises, benefits from a unique identifier, associated with a user at a computer server 40, allowing consultation and controlled dissemination. electronically, for example information associated with the display panel 20, and this in real time for example.

Thus, according to one embodiment, the present invention may require only one passage of a bailiff to assign a visual recognition of the information on the unique identifier of the display panel 20. Once this finding made, the report can be scanned and associated with the unique identifier of the display panel 20 at the computer server 40. The integrity of the positioning data and the physical integrity of the display panel 20 then avoid the need for another passage of the bailiff.

According to another embodiment, the passage of a bailiff can be avoided via the use of third parties by means of an internet platform in the form of a software application or a web page for example.

The present invention thus relates to a software platform, or even an internet observation platform that can be executed on a mobile device such as a smartphone, for example, and is designed to allow third parties to make a finding and observations when they are at home. near the display panel 20, this to clarify that the display panel 20 is clearly visible from the public road 3 for example and to mention the information it includes, or to transmit a photograph.

Thus, this platform can allow the taking of at least one picture of the display panel 20 and its encryption on the computer server 40 with which the platform is in communication to ensure the information exposed.

Thus, according to one embodiment, the unique identifier of the display panel 20 can be broadcast near the display panel 20 via technologies such as number, barcode and / or QR code printed on the front panel or else via an RFID transponder, a Bluetooth beacon or even a Bluetooth Low Energy beacon.
