FR2917526A1 - Digital data or file processing method for e.g. audio-visual field, involves providing reception device, digital data or file storage medium and transmitting device, where medium stores digital data or files on non volatile memory - Google Patents

Abstract

The method involves providing three main devices such as reception device, digital data/file storage medium e.g. bank terminal, and transmitting device, where the medium stores digital data/files on an open/locked rewritable/non rewritable non volatile memory. The medium is provided with a microprocessor which is different from a storage chip, and the receiving device is used as interface for capturing files of the medium towards an unspecified data processing apparatus. The transmitting device is used as an interface for remote loading of files starting from a database towards the medium.

Description

to the fact that during reading, the user can physically access the

  storage core through the player mechanisms that intervene directly on the basis where the data is stored.

  Storage media comprising an electronic chip combined with a magnetic tape are vulnerable either by the possibility of copying and duplicating data contained on the magnetic tape engraved on their physical surface, or by the physical capture of the storage medium in a device ( for example a cash dispenser) for subsequent fraudulent exploitation of the medium after visual or constrained recovery, complementary identification (identification) and unlocking codes. The presence of identification numbers on the surface of media for banking use poses an additional risk of fraud by the fact that with these simple figures it is possible to fraudulently use the support (case of mail order). Some recent devices always use magnetic waves for data transfer for reading or storing data. These devices are developed in advance with readers of their own and operate on the principle of contactless. These contactless cards are used for applications limited to purse roles for limited amounts or a ticket or identification badge for remote opening of certain accesses. They include an electronic chip that contains limited data and defined for a specific use (identification of a product among others in a stock) and an antenna connected to this chip. Some of these contactless cards may be composed of one or more other non-contact devices connected to the same antenna and acting independently or not from one another according to the applications. These contactless technology cards therefore have limited functionalities by their destination applications for which they are developed. For example, a user could not have his public transport subscription card which would at the same time serve as a cinema subscription card and storage medium for his favorite artistic works and / or other applications such as banking on a computer. same memory base and readable by readers different from each other and each of which is specific to a present and accurate application on the map. Nevertheless, some new technologies offer multiple functions based on contactless communication (bluethooth), a principle that requires the presence of a master master device to which other slave devices are connected and totally dependent. These technologies are generally limited to use for non-extensible private applications. This is the case of domestic mobile devices connected and dependent on a main terminal that broadcasts.

  Contactless cards used for wallet applications have, in addition to their lack of versatility, a very limited security in terms of debits in case of theft or loss; this results in a limitation of the balances that can be contained on this type of card in order to limit financial losses that can be significant. Indeed, in case of loss of such a contactless wallet card, it is possible for an individual who finds it to debit fraudulently at a merchant with the appropriate reader for this type of card that does not have elements of owner authentication such as a code or other.

  The current method according to the invention overcomes these disadvantages of wear, lack of security, lack of ergonomics and versatility that are for contact media, mainly due to direct physical contact between the mechanisms of the treatment device of data (drive or burner) and the media storage base. To overcome the drawbacks of duplication or capture abusive and physical media, this method is based in particular on a principle of communication by magnetic waves between the main elements (reader, storage medium, burner).

  The disadvantages of security and lack of versatility presented by current contactless storage media are remedied by the principles presented in this invention. Indeed, according to the embodiments, the readers intended for electronic money applications have a personalized authentication device in addition to the identification codes programmed in the matrices of the readers. For example, the carrier of the storage medium developed in this invention can simultaneously have personal files downloaded to a video rental terminal, personal files on a support that serves as a bank card. And each function (depending on the type of files) is executable on each terminal or appropriate reader and intended for this function or application (a bank terminal only supports the data relating to the bank and nothing else) regardless of the rest of the files contained on the media.

  The method of this invention is therefore based on three complementary and independent elements of each other. 25 It comprises in fact according to a first characteristic:

  1. A device (apparatus) particularly developed for the capture (reading) of files contained on the storage medium developed, and the transfer of these data to the processing unit (broadcast screen, terminal or other).

  2. A file or digital data storage medium operating with magnetic waves for transmitting this data to the reader and capturing them during a download. 3. A particular device (transmitting device) for sending files to the storage medium.

  All of these devices communicate exclusively by magnetic waves. There is thus no physical connection between these elements of the method which have antennas for the transmission and reception of data or files. The different devices (devices and storage media) have specific matrices coded and programmed into their microprocessors / microcontrollers. The operation by magnetic waves eliminates the friction traditionally due to repeated contacts between the elements that generally make up this type of assembly (readers + storage medium). This recourse to the use of magnetic waves then allows a better physical protection against theft (untimely capture of the support in a terminal), a logical protection against piracy and in short, a protection of the very base of storage against wear in that the mechanisms of the reading or engraving device no longer physically come into contact with the support. The transmission of data or files between the devices of the present method is therefore carried out without contacts. The use of magnetic waves has an additional advantage against reading or duplicating any magnetic tape appearing or printed generally on the surface of the media (bank card for example) or acting as a storage tape on media such as cassettes for example. A physical capture that can prove to be fraudulent and generates several disadvantages, a support in an apparatus is eliminated by this use of magnetic waves. The N which traditionally appear on current media (bank cards) and which are susceptible of fraudulent use, according to the method of the present invention they can be programmed in the matrix of the storage medium during the design thereof. We then eliminate their presence on the support therefore within the scope of fraud or improper use. These numbers or N which serve as identification of the supports are often used for the purchases by correspondence, a user having on his computer of the reader developed this will not need to compose these figures codes because it is enough to put his card near the reader so that during identification these code numbers are identified to authorize the transaction. For transactions for amounts greater than a threshold predefined by the owner of the card it will identify with the identification device present on the readers.

  According to the particular embodiments:

  - The device (device) for capturing (reading) files acts as a physical interface for catching magnetic waves of data contained on the storage medium, and then for transferring them to the monitor (terminal or screen or terminal of payment or diffuser sound) to which it is nested or connected by a cable provided for this purpose. This device is considered by default as a reader. It can have for banking applications an individual authentication device for securing debits or transfers of certain amounts whose threshold is predefined.

  - The transmitting device serves as the physical interface for downloading magnetic wave files from a database to which it is previously connected or nested, to the storage medium by magnetic waves. This device can be customizable according to the missions to which it can be intended. This personalization may comprise, for example, an additional security device (personalized identification of a user).

  - Non-nested transmission or capture devices (devices) in a display or data processing device have their own operating controls.

  > Transmitting or capturing devices nested in a device are themselves furthermore considered as peripherals of this main peripheral in which they are integrated, and use the standard commands of this main peripheral in addition to their respective respective commands. For example, a reader (data capture device) embedded in an automatic cash dispenser is considered peripheral of this dispenser and has the same start-up commands. > The functions of the capture device and the transmitting device can be combined into a single system which is considered a full-fledged device (apparatus). For example, a device combining the two functionalities (transmission, reception) can be intended for domestic or computer audio visual applications.

  - According to development, a versatile device for computer applications can perform all kinds of applications (monetary, entertainment or other) that would be present on a storage medium.

  > The interaction between the storage medium and the receiving or transmitting devices is exclusively by magnetic waves via their respective integrated antennas. - Digital files (data) can be stored on the media with their pre-established original formats regardless of their type (text, images, sounds or other). Storage media may differ depending on whether they are rewritable or non-rewritable and depending on the types of files or data supported. Files contained on a medium could not be modified if it was defined as a locked medium at design time. - The storage media and the reception and transmission devices have microprocessors or microcontrollers with coded matrices of their own and which allow them to interact only with each other and to secure the data. - The matrices of the devices and the storage medium can be supplemented by a programming that allows them to interoperate, according to development and destination applications. - The type of chip used as storage memory for the media may differ depending on the usage application of the media or the desired capacity. These memories used for storing data in the storage medium are nonvolatile memories. All the devices of this invention are only interactive with the magnetic wave protocol storage medium.

I. THE TRANSMITTER RECEIVER

  The transmitter receiver or recorder serves as a physical interface between the storage medium and the broadcast or display file processing apparatus to which it is connected or in which it is nested. This device is said to be versatile because it provides the functions of receiving and issuing files regardless of their type (text or audio or currency or other). It has integrated antennas in its circuit and is powered with the energy of the device to which it is connected or nested. After powering up, these antennas emit low frequency magnetic waves with a range of between 0mm and 100mm and when a storage medium is nearby, the waves emitted by the transmitter receiver awaken by micro vibrations the passive antennas of the support storage and provide it with the energy necessary for its operation (remote power supply). Through these magnetic waves, the transmitter receiver sends a digital interrogation signal for generic identification of any storage medium. This signal is a common piece of code programmed in the matrices of all the devices (transmitters and receivers) intended to interact with the storage medium developed here. It prevents them from interfering with other possible devices or media using magnetic waves such as those that currently exist.

  This signal makes it possible, among other things, to identify by default any storage medium whatever its category (exclusively monetary storage medium, or for computer or multipurpose use). The matrices programmed in the microprocessors of the devices (receiving and transmitting apparatus) comprise other code elements which make it possible to identify the category of the medium (electronic payment, entertainment, or other) and of its nature which defines two types of rewritable media and non-rewritable media. This programming of the codes in the matrices of the devices, differs according to the destination of use of each device (device) which is defined during its design and its development with the desired configuration. In fact the programming of the matrix of a multi-role device intended for use with applications on a computer tool will not be the same as that of a device intended for use for strictly audiovisual or electronic applications. The code element for the general identification of the storage media vis-à-vis the reading and transmission devices, remains unique in all matrices thereof.

  There are then two types of devices capable of performing the functions of transmitting receivers according to whether they will support a certain category of storage media (for example strictly banking support and support for strictly domestic applications) and not another and depending on whether the device (device) has been developed for a type of application (computer, audio visual or monetary). The definition of the applications of use and the programming of the matrices of these devices is done during their design. 10. The versatile transmitter receiver that is virtually developed for computer tool applications: Depending on the development, this device can support all applications that can be programmed on a storage medium. That is, in the programming of its matrix, all codes corresponding to the support of any application have been considered and programmed as such. Thus it can support the monetized applications contained on a support as much as the applications of leisures.

  In the programming of its matrix, there are code elements defined by a series of letters or numbers or signals that correspond to the code elements defined in the same manner in the storage medium matrix. When there is a storage medium near the device (device), at first the emitter receiver matrix generically identifies the storage medium by comparing storage category category definition code elements and then the type (open or closed) by performing a comparison between the sequence of the code elements of its matrix and those of the matrix of the storage medium simultaneously. Depending on whether code elements are equivalent or similar, the reader will support storage media and scheduled applications equivalent to one or more pieces of code.

  For example if there is in the matrices of the device and that of the medium, a code element which defines the electronic money application the device, after comparison and identification of this code element which defines the electronic money function, it will then be ready for the execution of this function in case of request from the user who carries the storage medium for electronic payment. As another illustrative and non-limiting example; in the matrix of a capture and broadcast (versatile) device in use on a computer tool and capable of supporting all categories of magnetic wave storage media and performing all possible applications; if a piece of code given and programmed in this matrix is equivalent to an application for reading a certain type of file present on the storage medium, a code equivalent (to the code programmed in the matrix of the apparatus) will be programmed in the storage medium matrix so that it is identified as such by the transmitting receiver device and as carrier of said type of files only or in addition to other types of files corresponding to the predefined application. In this case, the sending receiver will automatically support the type of file thus identified. With this type of device (transmitter receiver) installed on a home computer tool, the user can make several applications on his storage media (those of this invention) such as storage for download or reading works on a rewritable medium or non-rewritable contactless, or online purchase with a contactless wallet while using a single reader, that of his computer. These applications can be joined independently of each other on a single medium.

  2. The versatile transmitter receiver for home and leisure applications developed differently than the device usable on computer tools. This device is able to send files and receive them. Only the programming of its matrix is not the same as that of a device that supports one or more applications. Indeed it is not interesting to develop this support for home audiovisual use with a possibility of electronic payment. If several types of files or applications are contained on a storage medium and the user has a transmitting receiver device (device) intended for audio and / or visual applications only (device for home entertainment applications), the matrix of device, for this type of application will have in its programming, only the code elements that allow the support of all types of storage media carrying files applicable in home entertainment and entertainment applications.

  Access to the functions of a transmitting receiver device integrated in a computer or audiovisual device is done by the commands of the host device of the device by acting either on the virtual interface that starts when the transmitter receiver locates the proximity of the storage medium and identifies it as such, either by accessing the support by the menu or the workstation function in the case of an application on computer station through the icon which then represents the storage medium. This type of device (device) is powered by the energy of the host device (a computer, a payment terminal or other) via the shared connections.

  The transmitting receivers may be independent, that is, not nested in another device and have their own controls. These independent transmitter receivers (not nested in a device but connected to it by a suitable cable) for computer applications, have their own controls with a power supply that is via the connection cable to the device (computer or visual audio or other). This configuration may also be applicable to a device intended for audiovisual applications where the transmitter receiver is then considered as a separate independent storage medium reader with clean displays (same functions as a conventional VCR tape recorder or player player). 30 drive recorder for optical media), and according to development, remote controls (remote control).

II.The Simple Receiver

  The single receiving device or specific reader is devoid of the transmission function to the storage media and provides only the function of capturing or reading files contained on the storage medium and the transfer to the recording device. data processing. Unlike the multi-purpose transmitter receiver intended for computer applications, this type of receiver has a programming of its matrix strictly limited to the applications for which it is intended or to the types of supports it intended to support. It can then be broken down into several models according to all current current applications that can be substituted for the storage medium described above. There can therefore be devices (storage media reading devices) for public money applications such as bank distributors, payment terminals, leisure readers, gaming or other. Depending on the development and destination application, it can be compatible with all types of storage media, rewritable or non-rewritable but can not perform the transmission function that would be equivalent to loading files on said storage media. This type of receiver is therefore by definition intended for applications that currently do not need to issue information on storage media (bank terminals, payment terminals). Such as entertainment applications such as virtual games, portable entertainment audio devices or vehicles, banking applications and others. The readers intended or supporting banking or monetary applications such as payment terminals operating with the storage medium developed here, have additional specificity in addition to those described. The main specificity allows the securitization of data rates on contactless monetary applications by a physical authentication system of the carrier. This prevents a user from fraudulently debiting any medium that does not belong to him.

  This security is materialized by a carrier identification device by elements of his fingerprints which are stored in the payment medium (payment card) during its design before delivery to the future carrier. When paying with contactless support at a merchant, if the amount is greater than a predefined threshold (by the bearer and his bank) that does not require authentication, the bearer identifies himself by affixing his finger on the present device. on the terminal of payment or withdrawal. By identifying the storage medium, the reader matrix takes into consideration the code elements preprogrammed on the medium and equivalent to the digital data of the wearer.

  And when the amount to be paid is greater than that preprogrammed on the payment medium, the reader (payment terminal or terminal or other) having identified the type of media and furthermore taken into consideration the parameters corresponding to the maximum amount authorized and defined as debitable on the medium without authentication of the carrier, asks the user to identify himself by affixing his finger on the identification scanner, the elements of this finger are then scanned and compared to those issued by the support during its identification.

  That is to say that the reader (of the payment terminal) during his analysis of the matrix of the support (payment) he considers, on a determined scale, the code elements defined as corresponding to a flow rate up to one certain amount without taking into account the rest of the other elements of the scale; and when this amount is exceeded on this (coding) scale, the flowchart reader analysis process hangs until the code (string) scale is complemented by the preprinting elements. considered during the analysis and pre memorized by the reader (payment terminal).

  These elements (of physical identification) are thus analyzed in the same way and under the same protocol as the elements of code of the coded chain of identification of the support.

  The single receiver can be completely independent when it is not nested in another device by having its own operating commands and a clean power supply in particular in its leisure configuration. It is then considered as a separate storage medium reader with its own displays if it is not integrated into a data processing unit such as a terminal for monetary applications.

III. Storage support.

  Storage media are defined according to their purpose of use (exclusively leisure, monetary support, multi-purpose support or multi applications) and by type of supported files (text, audio, images) and by the fact that they are rewritable media with a possibility of multiple uses or non-rewritable with a limited use to one or more functions. They have nonvolatile memories open or locked according to the intended use that is defined during the design. The storage media have their own microcontrollers with matrices that contain code elements that define them with respect to the receiving devices and / or transmitters. These codes also define the type of support and functions applicable on the medium. In fact, a non-rewritable medium will be identified as such by the sending receiver and the file transmission function will not be activated. At the time of comparing the matrices at the transmitting receivers, only the code elements programmed in the support will be taken into account and applied as such according to their predestination function. By way of nonlimiting illustration, this process of comparing the matrix elements takes place on a principle of Si then and. As an example of a matrix: If open storage medium corresponds to open storage medium then open storage medium can be supported. Open memory storage media with the possibility of repeated uses have a coded matrix so as to allow the reception and deletion of contained files. Their identification code element differs from the identification code element of locked memory media to enable them to be recognized as such at the time of comparison by the matrix of any device. Storage media have built-in extra flat antennas for data transmission and reception. These antennas are powered by the waves emitted by the capture or emission devices. The micro vibrations produced by the magnetic waves emitted by the device allow the remote power supply of the storage medium and its memories. Locked memory storage media may have an additional combination in the coding of their arrays according to development at the time of design, for the protection of contained files against abusive copies at the time of reading. This additional protection is concretized by one or more code particles added to the matrix and then to the root of the files contained on the memories of the medium and at the time of identification of the medium by a reception device 35 capable of copying these files, these particles. codes are taken into account when comparing the matrix and when transferring files for reading. During a reading with an attempt to copy the protected work on a medium, the receiving device is programmed so as to perform all times X a comparison between the elements of its matrix and those of the storage medium matrix. and if at the time of this comparison the device no longer finds the complete combination of the code elements of the support matrix, the reading of the copied work fraudulently stops with a loss or a degradation thereof from the famous particle code that is programmed as such.

  III. The single transmitter or burner is the device that serves as the physical interface for a data holding apparatus or database that the user wishes to burn to the storage medium described therein. It can be nested to the device containing this database or connected to it with an appropriate cable. This device thus described, retrieves the data via the physical connection with the database and transfers thereafter by magnetic waves to the nearby storage medium in advance able to receive and support the transmitted files. This storage medium must first have a memory unlocked and coded as such.

  In addition to the matrix developed with this type of transmission device, a mini program is developed to allow it to be installed on certain types of machines that host databases (video rental terminals) and to promote synchronized interaction without requiring modifications. additional tool. The transmitter has antennas integrated in its circuit 35 for the transmission of files to the storage medium and these antennas feed with the energy supplied by the device to which the transmitter is connected. These antennas feed the antennas of the support and provide it with the necessary energy for receiving transmitted files.

  The entire device according to the invention is intended for all utility applications that are related to the storage, reading, burning and any other exploitation of files and / or data whether in the field of audiovisual leisure or professional, computer, electronic banking or other derivative multimedia applications such as video rental and others likely to be compatible with the devices described herein.
