Definitions

  • the invention relates to a method which is supported by an informatics system, which allows an automated identification of a document by a matrix barcode (also known as 2D code).
  • the method further makes it possible to access files stored on a server corresponding to the matrix barcode on a paper document.
  • the invention allows a transmission of a copy of file stored on the server by obtaining its location from a single sheet of paper by matrix barcodes. This transmission is made possible by inserting into a document a matrix barcode, identifying the said document and the path to this document on the server. This insertion of the matrix barcode is done by a computerized automated tagging process.
  • a transitory exchange is a combination of the virtual and physical formats.
  • One example is the use of a fax for the transfer of information.
  • Information in the virtual form is delivered (the electronic file) in a physical form (the sheet of paper) by the fax.
  • One object of the present invention is to provide the transmission of an electronic file (or documents) via a physical support.
  • the creation of a file code type allows a user to send several files from a unique paper document to another user in an electronic format.
  • the file code provides supplementary information (represented by a set of files) attached to a single document.
  • the process allows a file to be sent from a distant server to a smart phone or tablet computer after the processing of the matrix barcode by the server.
  • the server where the file are stored (herein the “storage server”) may be a cloud storage service, or any other type of storage server accessible through Internet or other computer networks, private or public.
  • a barcode is attached in an automated manner to a file or document. This automated attachment is performed by a computerized application identified herein as the “process monitor”.
  • the method allows monitoring of the file requests through a management of passwords specific to each matrix barcode.
  • the use of a password allows control by the owner of the documents regarding the broadcasting of said document, levels of access to the document and extent of editing of the document.
  • the documents can be transferred to the e-mail address of the user requiring access of the document.
  • the web server can therefore create a database of users' e-mail addresses for users having requested access to the documents.
  • a method of tagging a document for future access is automated and does not require human intervention.
  • the method includes steps of: uploading of a file by the user on a web server (or internet hosting platform); hosting a file containing said document using said internet web server; downloading of said file by a process server once it has been detected by the process monitor; uploading of said file on a storage server; memorization of access path by the web server to said file in the form of an web link; memorization of parameters chosen by the user by the process monitor; associating tagging parameters to said file, wherein tagging parameters include access restriction parameters; downloading (transferring) said file and said associated tagging parameters from the said internet hosting platform (web server) to a storage server and replacing the temporary copy by said file containing the tagging parameters in the storage server.
  • Memorization steps are methods allowing safekeeping of the information such as the tagging parameters and access in a database.
  • the process monitor continuously searches in the web server to identify said file to be tagged which are stored on the storage server, and once the process monitor identifies said file to be tagged, the process monitor download said file to be tagged from said storage server to a process server, this way the process monitor is generating an access path to said file on said storage server using a web link.
  • the web server contains a database comprised of web pointers (a pointer that indicate the location on internet of the document) and tagging parameters set by the user.
  • the file pointer contains the access path to the file to be tagged.
  • the tagging parameters may include the page of the document on which the matrix barcode is to appear, the position of the matrix barcode on this page and other such tagging parameters.
  • the method also has steps of creating a matrix barcode tag referring to said access path; inserting the matrix barcode tag into the said file according with said tagging parameters, wherein said matrix barcode will appear on said document; uploading (transferring) said file with inserted matrix barcode tag to said storage server at the location corresponding to said access path.
  • Transferring, copying, downloading and uploading files from one server to another server, or from or to the user's device, can be in push or get mode. Such actions can be performed over diverse internet protocols. These terms are therefore interchangeable for the purpose of the present invention.
  • the method also comprises an access restriction parameters include a user-defined password; the step of providing access to said file located on said access path only to third party users providing said password.
  • the method uses the QRTM code (Quick Response) technology as matrix barcode.
  • QRTM are a type of matrix barcode that already exists and is well known in various commercial applications. QR codes are available in several versions, each able to represent a certain number of alphanumerical characters in the form of a 2D barcode. This technology utilizes a two-dimensional barcode able to store information.
  • QRTM code of version 1 can represent a string of up to 25 alphanumerical characters, while codes of version 40 can represent a string of up to 4 296 alphanumerical characters. QRTM barcodes are also able to store numerical, binaries and Kanji/Kana characters.
  • the QRTM code contains the alphanumerical string which constitutes the hyperlink location (also known herein as “access path”) of the document of the tagged document on the storage server.
  • This two-dimensional code must be read by a QRTM code reader, which is often included in devices such as a smart phone.
  • the QR code does not need to be specific to the present invention.
  • the method then includes an automatic attachment of a QRTM code to an electronic document (for example, documents in the following format: WordTM 97-2003, WordTM 2007, bitmap, tiff, jpg, png, pdf, PowerPointTM 97-2003, PowerPointTM 2007, ExcelTM 97-2003, ExcelTM 2007 and other documents in digital format). This automatic attaching is performed by the process monitor.
  • any other type of matrix barcode which is able to contain alphanumerical strings adequate for the purpose of indicating the location of a the tagged file or folders on the storage server could be use for the present invention.
  • the invention's internet hosting platform hosts the documents at a unique location on a storage server which allows the identification of the document by the user. While the storage server is hosting the document, the web server continuously searches the database to identify a new file to tag. When a file is identified as being a file to be tagged, the process monitor retrieves the file by downloading it from the storage server (as on FIG. 1 ) to the server of the process monitor (the process server). The process monitor allows the retrieving of the initial file from the user and allows the tagging parameters to be seen by the user. Furthermore, the process monitor creates the matrix barcode by converting the hyperlink directing to the anticipated location of the tagged document on the storage server into a matrix barcode, which is generated by a sub-process of the invention.
  • the matrix barcode is inserted by the process monitor into the file. Finally, the process monitor returns the said file now containing the matrix barcode to the storage server (on FIG. 1 ). Once the file is tagged and returned to the hosting server by the process monitor, the monitor resumes the search in the database for files to be tagged and remains available to the user for downloading.

  • a sub-process may send a notice of availability to users having accessed said tagged file previously to let them know of the availability of a new document or a new version. For example, in cases where the query for document has led to a document being transferred by e-mail ( 412 ), each e-mail address can copied in a database on the web server, or alternatively on the process monitor. Once a new document or a new version is made available from the same selection webpage ( 410 ), either the web server or the process monitor may send a notice of availability to each of these e-mail addresses.
  • the process monitor continually or periodically search the database ( 500 ) to verify if a document needs be tagged ( 501 ). If no document is identified, the process monitor initiates a new search ( 500 ) for a document to be tagged. Therefore, the process monitor will perform periodical searches, and not other actions will occur until a document to be tagged is found.
  • the monitor downloads the initial file with its tagging parameters on the process server, for example, WindowsTM server ( 502 ), then the document is retrieved by the “monitor”, it also retrieves the tagging parameters.
  • the monitor retrieves the unique identifier which is an internet link (access path of the document) for the generation of the matrix barcode ( 503 ).
  • the monitor saves the image representing the matrix barcode on the server ( 504 ).
  • the monitor analyses the file type of file which has to be tagged. This process is done using the file name extension ( 505 ). For example: if the file extension is .doc or .docx ( 506 ), the monitor may open the Microsoft.Office.Interop.Word library ( 507 ) or any of such library allowing similar operations for the purpose of the invention.
  • the monitor may open the Microsoft.Office.Interop.PowerPoint library ( 509 ). If the file name extension is .pdf ( 510 ), the web server may open its PDF library or the monitor's own library for PDF files ( 511 ). If the file name extension is .jpg, .jpeg, .png or .tif ( 512 ), the image-processing web server will use its image processing library or the monitor will call System.drawing ( 513 ) and for each document in other formats corresponding editing processor would be used.
  • the process monitor verifies the tagging parameters as a function of the said file type ( 514 ) storing the information on tagging parameters and the opened library for further processing ( 515 ).
  • any library adapted to processing the file type of the document may be used, and specific libraries may be programmed as a function of specific file types or integrated within the process monitor.
  • the monitor opens the file of the document and affixes the matrix barcode at a specific location following the tagging parameters ( 616 ).
  • the process monitor determines the coordinates for affixing the matrix barcode on the page of the document ( 618 , 620 , 622 or 624 ).
  • a review of the code request page is done ( 625 ). If the number of the page is higher than one ( 626 ), the system will find the precise page ( 627 ). If it is not higher than one, the barcode will be applied on the first page only ( 628 ).
  • the matrix barcode is applied on the document having as content the unique identifying Internet link ( 630 ).
  • the file is then returned to the cloud storage server by the monitor ( 631 ).
  • the document appears as tagged ( 104 -B) in the database ( 104 ).
  • the invention provides an automated method to identify documents needing to be tagged, and documents that have been tagged.
  • the document remains available when the matrix barcode linked to the document is scanned and also when the owner of the document accesses it, using its web server user account ( 103 -B).
  • the tagging process is also used within third party applications such as Microsoft WordTM, Microsoft PowerpointTM or ODT file editors on the computer used to create and edit the document ( 700 ).
  • third party applications such as Microsoft WordTM, Microsoft PowerpointTM or ODT file editors on the computer used to create and edit the document ( 700 ).
  • the user of the document can tag directly the document using an add-on feature represented as an icon in the third party application.
  • the method can comprise the additional feature of installing the add-on feature on the edition software used, said add-on feature comprising a native monitor ( 701 ).
  • the native monitor is therefore on the same computer ( 700 ) used for editing the file ( 702 ).
  • native monitor sends a query ( 704 ) to the web server, which sends back the information on the location where the tagged document will be on the storage server.
  • the native monitor ( 701 ) then creates a matrix barcode corresponding the this information, and affix the QR code to the document, thus creating a tagged document ( 706 -A) on the user's computer ( 700 ).
  • the native monitor continues by downloading ( 707 ) a copy of the tagged document on the web server ( 706 -B).
  • the web server in turn downloads ( 708 ) its copy of the tagged document on the storage server ( 709 ), thus creating yet another copy of the tagged document on this storage server ( 706 -C) at the previously determined hyperlink location. It is this copy on the storage server ( 706 -C) that will be available for other users to access using the matrix barcode on printed versions of the document.
  • the copy of the tagged document on the web server ( 706 -B) may be deleted once the download is complete.
  • the native monitor generates a QR code and a hyperlink to access the tag document on the storage server through the use of said QR code.
  • an electronic version is created containing the tag.
  • This tagged document is then downloaded and saved on the storage server through the web server and the native monitor creates a temporary copy which will be saved on the local computer used for further editing the document.
  • the storage servers and monitors of the document marking system in any of the listed above arrangement or in a combination of those arrangement.
  • Each part of said system can be locally or remotely positioned, depending on the security level, economical considerations and practical decisions understandable by a person skilled in the relevant art.
  • the marked document can be stored on the overseas server to reduce the cost of the document storage.
  • the present invention could be used, for example, for educational application.
  • a teacher could bring a printed tagged document to his students. Only students interested to said information would then use a QR code reader to obtain a copy of the document, which can then be consulted by the students using any preferred device.
  • the QR code could point to a selection webpage from which students would be able to download several other documents related to the printed document they saw.
  • a teacher could also provide multiple or updated versions of his courses to his students, by updating the document associated with the QR code or by making available a plurality of updated versions, including, for example, recent news events related to the taught subject.
  • a lecturer at a conference would show the QR code of his conference presentation to the audience, which would then be able to download a copy of the presentation.
  • the QR code tag could be displayed on the presentation screen at different moment during the presentation. Alternatively, it could be printed on a separate sheet from the rest of the document, and therefore the QR code tag could be circulated amongst the viewers, or alternatively displayed on a computer or on any physical display made available for viewers to scan QR codes corresponding to the desired presentation. It would also be possible for the presenter to add new material associated to the QR code in real-time during his presentation.
  • the Web server or the Process monitor could automatically generate a display of a plurality of QR code corresponding to a plurality of presentations, for example for a plurality of presentations on related topics or given at a same event. Afterward, if one of the members of the audience wants to share this presentation with another person, this member of the audience would only need to show the QR code of his own printed version to this other person for that person to obtain the presentation. Finally, all these persons would be able to access, using the same QR code, updated versions of the same presentation and other related documents made available by the lecturer on a selection webpage.
  • documents which are prepared by police officers can be tagged with a QR code, with a plurality of security levels attached to a plurality of documents which are partially masked as a function of security level.
  • a user with no or limited security access level will enter, when requested by the system, the low level security password. This user will then have only access to the heading of the document, the rest of the document being masked and blanked out.
  • a user with intermediate security access level will enter a medium security password, providing him access to documents partially masked or blanked out, as a function of his level of security.
  • a user with the highest security access level will have to enter a password that provides access to the complete document.
