Description

Title: TRANSFER PROCESS OF A MEDIA ASSOCIATED WITH A

PHYSICAL MEDIA The field of the invention relates to the field of methods and systems aiming to transfer a medium from a first user of a service to a second user of the service, said medium being associated with a physical content itself to be transferred. The field of methods and systems of the invention relates in particular to solutions ensuring the security of a transfer operation while offering a simplified operation for each user.

When a user sends a physical medium, such as a letter, to another user and wants to associate digital content with it, there are different methods. The most common is electronic messaging. However, this solution requires special management of the association of the physical medium and the transferred media. A difficulty arises when a large number of users have to be addressed. Indeed, the number of operations of association of the media with physical media considerably increases the complexity of management to be implemented and the errors. An error can be extremely damaging when the medium does not correspond to the information written on the physical medium, for example when it concerns medical data.

There are alternatives when the physical medium can be digitized, in fact this makes it possible to digitally associate the content of the physical medium with the media transferred, for example by courier. In the latter cases, the information can be grouped together and therefore be transmitted together. However, this solution also imposes a more complicated operation since it is necessary to digitize the document, for example by scanning it.

However, for certain use cases, it is necessary to transmit a physical medium. Indeed, certain practices are very useful in many professions organized so as to involve different trades to carry out an operation or to provide expertise or advice. Typically, a medical specialist or a dentist may be required to send a physical letter to a laboratory, a service provider or even a colleague to indicate recommendations, an analysis or details of a diagnosis. It may also be a specification for making, for example, a prototype such as a crown for the dentist, a sole for the podiatrist or contact lenses for an ophthalmologist. The data recorded on the physical medium can be a sketch, a sentence, figures or any other information. This information is often combined with photos, a video or a sound file to substantiate the information. However, this information is most often in a digital format and is stored in a memory of equipment of a user such as a doctor.

Currently, digital data and physical media are sent separately. This leads to errors of association or to the implementation of a solution that is difficult to maintain in use.

In addition, there is the possibility of using a physical medium specially designed for the recipient comprising a code to be scanned, the latter of which makes it possible to integrate data specific to the recipient, an identifier specific to the patient or to a particular file. This code makes it possible, for example, to associate a reference to it in order to create a link with a medium. These solutions, however, require the design of a physical medium specially adapted to the use case. Typically, it is necessary to define patient data or that of the recipient of the medium or other information to generate an appropriate code and then print it. Thus, by scanning the information, the recipient can digitally associate the physical medium and the medium which must also include an encoding to certify that the medium is indeed linked to this medium.

This solution, if it offers a means of simplified management, is no less complicated to set up. Indeed, it is necessary to integrate a digital reference within the media and to transfer them to the recipient so that they are subsequently associated with the transferred physical medium.

There is therefore a need to define a solution which can respond to this problem of simplifying the procedure for transferring digital media associated with a physical medium such as a letter. Simplification sought should minimize the operations of exploitation of the exchanged content while offering security in the mode of transfer of information, whether physical or digital.

The present invention aims to resolve the aforementioned drawbacks. According to a first aspect, the invention relates to a method for transferring digital media from a first memory to a second memory, said first medium being associated with data recorded on a physical medium, characterized in that it comprises:

^■ Generation of a first set of graphic codes each comprising an encoding of a unique given digital address addressing a location of a given memory of a remote server, said remote server being connected to a data network;

^■ First selection of at least a first graphic code from the first set; ■ Printing of said at least a first graphic code on a first physical medium;

^■ Reading of the first graphic code from a first device comprising an optical reader;

^■ Identification of a first user with an access management server to make the memory accessible for writing to the first user;

^■ Second selection of a first medium recorded in a first memory and downloading of said first medium within the location of the given memory of the remote server; ■ Reading of the first graphic code from a second device comprising an optical reader;

^■ Identification of a second user with the access management server to make the memory readable to the second user; ■ Third selection of said first medium recorded in the given memory and reading and / or downloading of said first medium within a second memory.

According to one embodiment, the printing of at least a first graphic code on a first physical medium automatically results in the non-availability of the first graphic code for another use. According to one embodiment, the step of selecting a first graphic code comprises the selection of at least one graphic code not yet printed, each first graphic code of the first set comprising an availability status, said availability status being stored in a memory of the remote server.

According to one embodiment, the graphic codes generated from the first set include by default an “available” status.

According to one embodiment, printing a graphic code automatically causes the availability status to be changed to "unavailable".

According to one embodiment, a graphic code with an "unavailable" status is not selectable from the first set.

According to one embodiment, the first selection step is automatically performed according to a predefined sequence within the set of graphic codes, taking into account the availability status of the graphic codes.

According to one embodiment, the method comprises a step of entering data on the physical medium by the first user.

According to one embodiment, the method comprises a step of generating a tracking number comprising an alphanumeric series printed on a border of the QRC code. Advantageously, this tracking number is unique. According to one embodiment, it is printed so that it is collocated with the QRC graphic code. According to one embodiment, it is printed in an area common to the QRC graphic code.

According to one embodiment, the graphic code does not include any information describing or associating a user.

According to one embodiment, the graphic code only comprises data describing links to a physical resource accessible in a data network and / or a software resource accessible within a terminal or a server.

According to one embodiment, each graphic code includes a link to a location of a single remote physical resource, two graphic codes taken two by two from among the set of codes generated from the first set not addressing the same location of one. remote physical resource. According to one embodiment, a medium recorded on a remote memory is automatically deleted after:

^■ Downloading of said media by a second user;

^■ A predefined time elapsed after a download performed either by the first user to save the media to the remote memory or by the second user to play or download the media from the remote memory,

^■ A predefined number of graphic codes generated.

According to another aspect, the invention relates to a computer program product comprising at least one memory and one computer, said program comprising program code instructions executed on a computer for implementing the steps of the method of the invention. .

According to one embodiment, the computer program product comprising a computer and a memory, a user interface and a communication interface.

According to another aspect, the invention relates to a terminal comprising a computer, a memory and a display for implementing the method of the invention.

According to another aspect, the invention relates to a system comprising a plurality of terminals of the invention, and at least one server configured to collect the media data sent by said terminals and to manage write and read accesses of users s' being identified or authenticated with an access management server.

Other characteristics and advantages of the invention will emerge on reading the following detailed description, with reference to the appended figures, which illustrate:

Fig. 1: an embodiment of the invention comprising a first set of steps allowing a first user to transfer a first medium to a second user, in particular via a remote server; Fig. 2: an embodiment of the invention comprising a second set of steps allowing a second user to download the first media; Fig. 3: an example of a system of the invention for carrying out the method of the invention.

Generation of QRC codes The method of the invention comprises a first step, denoted GEN (ENS-i) in FIG. 1, of generating a set ENSi of graphic codes, denoted QRC, each being intended to be printed only once on a physical medium. , denoted SP, such as a sheet of paper. According to another example, it may be a plurality of sheets, such as two sheets. In this case, the QRC code can be printed on each sheet. According to another alternative, the QRC code is displayed on the first sheet. QRC graphic codes are generated from a sequence of generated digital data encoding a graphic representation of said sequence of data.

One advantage is to secure the transmission of a medium via this QRC code by its unique imprint. By guaranteeing the uniqueness of the printing of the QRC code on a physical medium SP, the method of the invention assures a first user that only a second user receiving the physical medium SP comprising the unique QRC code will access a link to transferred media.

The QRC graphic code can be of different shapes, types or appearances. Depending on the case, the graphic code is a 2D code, such as a QR code, a Flash code, a Datamatrix, a Semacode, a Bee Taag or an Aztec code. Any other graphic code can be used within the scope of the invention. Any code of this type is denoted as QRC code in the present invention.

According to another embodiment, the code is a 1 D code, that is to say a one-dimensional code. It can then be a bar code or a sequence of linear signs encoding information. In order to simplify reading, in this case the code is also called a QRC code in the remainder of the description.

According to one embodiment of the invention, at least one QRC graphics code is generated. However, in a preferred mode, a generation of a plurality of QRC graphic codes is generated. Indeed, the invention is of particular interest when a large number of QRC codes are generated beforehand. In this case, each generated QRC code makes it possible to reserve a remote memory space MB which can be addressed by a link contained in the generated QRC code.

An advantage of the invention is to generate QRC codes independent of user data or of the nature or type of media. In this embodiment, the QRC graphic code does not include data encoding a user identifier or personal data such as a first name, last name, identifier, address, age, antecedent.

According to one embodiment, the QRC code comprises a number displayed within the graphic code, called the tracking number. The tracking number can be, for example, a 4, 5, 6, 7, 8, 9, 10, 11 or 12 digit number. According to other variations, it can be even longer. It can include any type of alphanumeric character and possibly symbols.

One advantage of superimposing a tracking number on the QRC code is to allow a user to quickly have a reference for the case being treated. The case may correspond to a treatment of a patient, an identified pathology, a particular intervention or any other event with which a medium is associated.

This tracking number may allow a user to annotate or archive the given case in transferred media management software or other software.

According to a first use, this tracking number can be used to reference the media in the management software. Alternatively, this tracking number can be used to verify the association by a second user receiving the SP physical media. Thus, it can be used to facilitate archiving or to verify an association between a physical medium and a transferred medium. When the Fi media is retrieved from the transfer server, corresponding to the remote memory, from the QRC code, the second user can quickly verify with the naked eye the correspondence between the reference of the media which is annotated with the tracking number. and the QRC code which is printed on the physical medium.

In a complementary embodiment, the QRC graphic code does not include any contextual information such as an address, a date, a user reference, a reference to a type of media, a reference to a pathology.

Thus, each QRC code has the advantage of designating a location in a predefined remote memory Mo to allow the transfer of a file from one person to another person. Each location is different from one code to another. Thus, it is impossible to assign the same remote memory location to two different physical media SPk and SPp. Each first user Ui is thus assured that the media transferred Fi via a remote memory Mo will not be accessible by means of another physical medium. In the remainder of the description, the terms “remote memory MB” or “location of a remote memory MB” should be understood for a given QRC code. Thus, this means that for a _{given QRC k} of a {QRCi} ien set _; N], a location of a Mo memory ^k is addressed. In order to simplify the reading of the description, the notation Mo is used in the remainder of the description to indicate a given memory space. This association between a physical medium SP and a QRC code makes it possible to reserve in advance for a later transfer a memory space MB thanks to the access link contained in the QRC code. This is particularly advantageous when a physical medium SP, must be exchanged between two users Ui, U2. The invention makes it possible to benefit from the existence of this physical medium SP, which is exchanged between two users Ui and U2 in order to define a link by which transmission of digital media F1 is made possible.

When a set of QRC codes is generated, the memory spaces are reserved and can be used later. The steps carried out from the terminal T1 of the second user Ui are described in FIG. 1. However, the generation of the QRC codes of the first set ENS1 can be carried out beforehand, for example from other equipment.

Selection of a QRC code subset for printing

The method then comprises a second step, denoted SEL-i (QRC) in FIG. 1, which comprises a selection of a subset of codes {QRCi} ie [i _; N] to print as many {SPi} ien physical media _; N] with a unique QRC code printed on each of them. This operation preferably comprises a selection of a number of QRC codes. This number can be determined, for example, from an editable field of a graphical interface. When the number of QRC codes is determined, a set of QRC graphic codes is extracted from the previously generated set ENS1. The selection can be a selection random set of generated QRC codes or a continuous sequence of QRC codes in a range of counted QRC codes.

Printing physical media

The invention aims to print a set of physical media {SPj}, e [ΐ _{; N]} with a unique QRC code dedicated to each print. The invention comprises a printing step, denoted IMPR (SP) in FIG. 1, of a set of physical media {SPj} ie [ΐ _; NOT]. In other words, on each physical medium SP, is printed a QRC code, different from the selection.

The method of the invention is particularly interesting when the physical media are loose sheets. No physical link exists between two physical media. They are therefore independent of each other. Thus, an SP physical medium can be chosen for one transfer case and another physical medium can be chosen for another transfer case without these two cases needing to be linked to each other. According to one embodiment, the selection of a set of codes

QRC automatically prints as many documents on which the QRC codes are printed. Thus, the actions of selections and printing can be combined in a single step. According to one embodiment, each printing medium comprises a unique QRC code of the set of generated QRC codes. To achieve this, printing software can be configured so that selecting a number of QRC codes is used to select a corresponding number of physical media. This operation can be carried out by a conventional direct mail operation. For example, if 200 QRC codes are automatically selected, this action results, according to the method of the invention, to the printing of 200 A4 size sheets on which a unique QRC code is printed from the list of generated codes.

The invention finds its main interest in a use where a first user Ui has several sheets {SP}, e [i _; NOT]. In the latter case, he just has to choose one for a given case, it doesn't matter which one. This can be, for example, for a consultation of a patient. In this case, the first user Ui is a doctor or a dentist and he can decide to associate this physical medium SP with images or videos stored in a memory. of electronic equipment, such as a Smartphone after having downloaded them to the single location of the remote memory MB.

One advantage of this solution is to pre-print physical media which will be used, for example, by a doctor, a dentist or any other profession using an SP physical medium to transmit data, for example, to a service provider, a partner or a laboratory. . This solution allows the data to be transmitted recorded on the physical medium SP to be associated with digital multimedia content.

According to one embodiment, once these prints have been made, the QRC codes are no longer available to be subsequently generated and / or used. This can be achieved through the use and exploitation of a QRC code availability status. In the latter case, management software allows each QRC code to be associated with a status so that it cannot be reused subsequently. According to another embodiment, the QRC codes are made unavailable by their removal from the set of previously generated QRC codes. This action implies that no selection can be made of a QRC code that has been deleted. According to another embodiment, a function making it possible to restrict their access by a user of the application is implemented.

According to one embodiment, these actions making it possible to make a QRC code unavailable are implemented at least for a predefined period of time or beyond a given number of generated QRC codes.

Encoding of URLs within QRC codes

Each QRC code encodes a link to the location of a remote MB memory within a NET data network, such as the Internet. This MB memory can be a physical memory if it is a memory of a server type device or a virtual memory if it is for example distributed among several physical devices.

According to one embodiment, this link is a uniform resource locator, better known in the English literature by “Uniform Resource Locator”, designated under the name URL.

The link encoded in the QRC graphic code can be decoded by electronic terminal means comprising an optical sensor. The decoding can be carried out using optical character recognition software, of the OCR type and dedicated to the QRC graphic code used. Any other type of software making it possible to decode a link encoded in a QRC graphic code can be used within the framework of the invention.

According to one embodiment, the QRC code also encodes a link making it possible to automatically open an application installed in the terminal comprising the optical reader. The application is, for example, a software allowing to exploit the link URL and the media to download them to a remote memory MB located by the URL.

According to one embodiment, the QRC graphic code encodes only at least one access link. This could be a link to a physical resource, such as memory, or a link to a software resource, such as an application, or both.

The use of an access to an application, is to allow a photo taking with a photography application and to automatically recognize that this photo must be exploited by an application whose link is contained in said QRC graphic code. Thus, this possibility makes the use of the Ti terminal more convenient so that it is not necessary to open a dedicated application before capturing the QRC code for its operation.

Reading the QRC code on the physical medium

According to one embodiment, the method comprises a step of reading the QRC code, denoted LEC1 (QRC) in FIG. 1, on one of the physical media SP which has been previously printed. Reading the QRC code and decoding it by the application of the first Ti terminal extracts the URL and automatically opens the link in a browser. This can be a browser for accessing NET data network resources, such as a web browser. Preferably, the first terminal Ti has a graphical interface making it possible to view the browser and the content stored at the location of the remote MB memory designated by the URL. If the memory space designated by the URL is not yet occupied by a medium, a first user is given the possibility of downloading a medium Fi to the remote memory, denoted MB. This memory MB is preferably that of a data server, denoted SERVo.

The terminal Ti is therefore provided with a communication interface for accessing at least one remote server SERVo of the data network NET. This communication interface can be provided by an antenna and a WIFI, 3G, 4G 5G type data transmission protocol, or any other type of data transmission protocol. Finally, all the electronic components making it possible to send and receive data are present in the terminal Ti.

According to one embodiment, when these QRC codes are selected, they become unavailable within QRC code management software. The unavailable status ensures, for example, that a subsequently selected code is identical to a QRC code already used for printing SP, physical media.

Use of the physical medium by a first user

A first user Ui of a physical medium Fi can use the latter to write data on the physical medium.

Identification of the first user

When the application of the first terminal Ti is used to access a remote memory space MB, the first user Ui is invited to identify himself. The method of the invention comprises an identification and / or authentication step with an identification and / or authentication service, this step is denoted IDENi (Ui) in Figure 1. The identification and / or authentication service can be hosted on the SERVo server or on another SERVi remote server.

The first user Ui identifies himself with an access management server SERVi to access the remote memory location Mo. For this, an application of the terminal Ti, called the client, makes it possible to acquire the identification data of the first user, such as login and password. These identification data are then sent to the SERVi access management server so that the first user Ui can access the memory space with write access rights.

Thus, the invention includes an identification step so that access to a MB memory space is reserved for a user of a service. This feature helps ensure that a third party accessing physical media with a QRC code printed on it will not be able to access the content at the remote MB memory location.

Thus, the identification of the users makes it possible to ensure that the digital media Fi are transferred between identified users of the same service. The invention finds its full potential in the combination of a means simple file transfer between two users and a means ensuring the security of the latter transfer by identifying users on a platform centralizing data exchanges. Thus, the method of the invention makes it possible to offer a trusted service insofar as a first user knows that a second user must connect to the service in order to retrieve the transferred media. Thus, the invention benefits from these two aspects offering the best compromise between ease of use and security with respect to the information exchanged.

When the first Ui user scans the QRC code printed on a given SP medium, the QRC code management application opens automatically. When the first user Ui has already indicated a username and password, identification and / or authentication can be performed automatically from the identification and / or authentication data pre-recorded in the terminal Ti.

Media transfer

From a Ti terminal, the first user Ui accesses a remote MB memory space. It is then able to transfer Fi media such as a photo, video or audio file or even a text file. This operation is performed by selecting a media Fi, for example, stored in a memory Mi of the terminal Ti and sent to the remote memory Mo. The media selection step Fi is denoted SEL2 (FI) in FIG. 1 Initially, the file Fi can be stored on a local memory Mi of an item of equipment of the first user Ui, preferably on the terminal Ti.

The step of transferring the file Fi, or in other words of downloading it, within a remote memory Mo, is denoted TELEi (F1) in FIG. 1.

Different protocols can be used to transfer the media Fi within the remote memory Mo. Among the protocols, there is for example the HTTP, FTP or any other type of file transfer protocols.

The transferred Fi media can correspond, for example, to an X-ray, a scanner, a photo of a dentition, a video of a patient, an audio file in which a doctor transcribes a diagnosis orally, etc.

Fi media is transferred and stored on remote MB memory at a given location. According to one example, a plurality of media Fi is selected and transferred by the first user Ui to the location of the memory Mo.

According to one embodiment, the media (s) Fi is / are stored for a predetermined duration on the remote memory Mo. According to one embodiment, the duration is calculated from the downloading of the media to the memory. by the first user. According to another example, the duration is calculated from the consultation by the second user U ₂ of the medium on the remote memory. According to another example, the F ₁ media is stored in the remote memory MB until a given number of codes to be generated QRC. When the predetermined duration or the number of generated QRC codes have exceeded a predefined threshold in duration or in number, then the media F ₁ is automatically deleted from the memory Mo so that the memory location can be reused.

According to one embodiment, a first user can archive all the media transferred within the remote memory Mo. According to one embodiment, this memory is organized by means of a database. According to one embodiment, the remote memory MB is provided with a file management system making it possible to optimize the archiving and to facilitate access to the archived media. According to one embodiment, a function making it possible to define an archiving field is configured within the memory Mo. This archiving field can be used to enter, for example, the tracking number, a type of event, an identifier or any other type of information used to archive the media. The first user Ui can also use a combination of these fields.

Reading of the physical medium by the second user

The steps carried out from the terminal T ₂ of the second user U ₂ are described in FIG. 2.

When a second user U ₂ receives a physical medium SP ₁ sent by the first user Ui, he accesses a data item written on the physical medium SP ₁ . From a second terminal T ₂ , provided with an optical reader, the second user U ₂ accesses the memory location Mo onto which the medium F ₁ has been downloaded by the first user Ui. The reading step is denoted LEC ₂ (QRC) in FIG. 2.

Identification of the second user Identically to the first user Ui, the second user U ₂ identifies with an access management server to access the remote memory location Mo. This step is denoted IDEIS C1h) in FIG. 2.

This step can be implemented by means of an application of the terminal T ₂ , called a client, which makes it possible to acquire the identification or authentication data of the second user U ₂ . These identification or authentication data are then sent to an access management server so that the second user U _{2 can} access the memory space Mo with read access rights. For this, the second terminal T ₂ is for example provided with a communication interface within the data network NET.

According to one embodiment, the second user U ₂ also has a write access right to the location of the remote memory Mo. This function allows him, for example, to in turn re-send multimedia files to the remote memory. Mo.

According to one embodiment, when a new user registers on the application offering the file transfer service F ₁ from a reading of a QRC code, a rights administration function makes it possible to manage user rights according to the function of said user. According to a first case, a user only has write rights, for example, if he is intended to send data to another user. According to a second case, this same user can be assigned write and read rights. According to another case, the user intended to receive files from another user can only have read rights. In another case, this same user has write and read rights.

Selection of media to download.

The method of the invention comprises a step of selecting a file F ₁ visible from the interface of the second terminal T ₂ of the second user U ₂ . This step is denoted SEL ₃ (FI) in FIG. 2. The selection of one or more files F ₁ allows the second user U ₂ to access and therefore read the file F ₁ stored in the remote memory Mo. According to a preferred mode, the second user U ₂ downloads the media to a local memory M ₂ of his second terminal T ₂ . This step is denoted TELE ₂ (FI) in Figure 2.

Thus, the second user U ₂ recovers the multimedia files F ₁ from the QRC code printed on the physical medium SP ₁ that he received from the first user Ui. Beforehand, this second user must identify himself or himself with a service common to that used by the first user Ui.

Management of several users

According to one embodiment, the invention makes it possible to connect several first users Ui with several second users U ₂ . For example, a dentist can work with different prosthetists and conversely a prosthetist can work with different dentists. It is assumed that these different users Ui, U ₂ use for example the application allowing access to the remote memory spaces Mo. It will be recalled that this application has the following minimum functions: an identification and / or authentication function of a user, a function making it possible to select a file and transfer it to a remote memory and a function making it possible to download a file stored in the memory Mo to an electronic terminal.

Among other functions, the invention allows a user to configure a directory comprising identifiers of other users. This function allows to manage download history and know for example if a second user retrieves a file _F1 that has been transferred to him.

Management of memory spaces

According to one embodiment, the files are automatically stored for a predefined duration on the remote memory MB. Thus the memory spaces MB are freed and can be reused subsequently when a large number of QRC codes have been generated.

According to one embodiment, when a number of QRC codes exceeds a predefined threshold, the memory locations already used are reassigned to other codes to be generated.

The invention is of great interest in the possibility of using the physical media SP to address different users U ₂ . In fact, the first user Ui does not have to worry about managing the second users U ₂ when he communicates to him a medium which is associated with a physical medium.

System of the invention FIG. 3 represents a system according to the invention comprising a remote SERVo server making it possible to host the file transfer service. This service is preferably provided by software installed on the server. In this example, the remote memory Mo is that of the SERVo server. According to other cases, the memory may be accessible from a server other than the server providing the service.

A first terminal Ti of the first user Ui is shown. A second terminal T ₂ of a second user is also shown. The system of the invention comprises at least two terminals, but depending on the use cases each terminal allowing access to the service hosted on the server So is included in the system of the invention.

According to different embodiments, each terminal includes either an access to a SERVo server to operate the main steps of the invention there, or a local client making it possible to pre-identify and preload the media.

The invention addresses all the modes of implementation of the process steps, whether they are carried out wholly or partially locally on the user's terminal or on the SERVo server.

FIG. 3 further shows a NET data network such as the Internet network.
