Description

PROCEDE DE SAUVEGARDE DE DONNEES CONTENUES DANS UN  METHOD OF SAVING DATA CONTAINED IN A
TERMINAL COMMUNIQUANT PORTABLE  PORTABLE COMMUNICABLE TERMINAL
La présente invention est relative à un procédé de sauvegarde de données contenues dans un terminal communiquant portable, notamment un Smartphone®. Actuellement, les terminaux de téléphonie mobile proposent de nombreuses fonctions utilisant ou générant différents types de contenu. The present invention relates to a method for backing up data contained in a portable communicating terminal, in particular a Smartphone®. Currently, mobile phone terminals offer many functions using or generating different types of content.
Ainsi, les terminaux téléphoniques les plus récents sont équipés de moyens d'acquisition d'images de type appareil photographique ou caméra, servent de baladeur numérique, de navigateur GPS®, permettent de gérer un agenda, de naviguer et de consulter sa messagerie sur Internet, d'installer des applications téléchargées depuis une logithèque, etc. Thus, the most recent telephone terminals are equipped with camera or camera-type image acquisition means, serve as a digital music player, a GPS® navigator, make it possible to manage a calendar, to navigate and to consult his e-mail on the Internet. , install applications downloaded from a repository, etc.
Devant la multiplication de ces fonctions, la quantité de données enregistrées s'accroît et les constructeurs sont obligés d'augmenter la capacité des moyens de stockage. Faced with the multiplication of these functions, the amount of recorded data increases and the manufacturers are obliged to increase the capacity of the storage means.
Les données enregistrées correspondent à différents types d'informations : des répertoires de contacts stockés dans le téléphone et dans la carte SIM, des fichiers photo, vidéo, et audio, des fichiers stockés dans la mémoire interne de l'appareil ou dans un support amovible tel une carte mémoire, des fichiers correspondants à des événements d'un agenda, à des mails, et des données créées par les différents programmes installés.  The recorded data corresponds to different types of information: contact directories stored in the phone and in the SIM card, photo, video and audio files, files stored in the internal memory of the device or in a removable medium such as a memory card, files corresponding to calendar events, emails, and data created by the various installed programs.
Selon l'utilisation de l'appareil, par exemple personnelle ou professionnelle, l'importance des différentes données est variable.  Depending on the use of the device, for example personal or professional, the importance of different data is variable.
Ainsi, les données liées au système d'exploitation de l'appareil et à sa configuration sont souvent considérées comme les plus importantes, tandis que les données multimédias et les programmes peuvent parfois être considérés comme moins importants car pouvant être rechargés depuis un autre appareil ou un serveur. For example, data related to the device's operating system and its configuration are often considered the most important, while multimedia data and programs can sometimes be considered as less important because they can be reloaded from another device or server.
Etant donné les probabilités des risques de perte ou de vol attachées à ces terminaux, mais aussi des éventuelles défaillances matérielles ou des bugs logiciel, différentes méthodes sont mises à la disposition des utilisateurs pour transférer leurs données sur d'autres supports.  Given the probabilities of the risk of loss or theft attached to these terminals, but also possible hardware failures or software bugs, different methods are made available to users to transfer their data to other media.
Ainsi, on trouve des applications pouvant être installées sur l'appareil pour enregistrer une image des fichiers les plus importants sur un support amovible dédié tel une carte mémoire.  Thus, there are applications that can be installed on the device to record an image of the most important files on a dedicated removable media such as a memory card.
De manière plus spécifique, les opérateurs téléphoniques, ou d'autres sociétés, permettent une sauvegarde à distance des répertoires de contacts. More specifically, telephone operators, or other companies, allow remote backup of contact directories.
Ces premières méthodes ne sont pas satisfaisantes car elles visent uniquement un certain type de données ou sont limitées à une certaine quantité de données. These first methods are unsatisfactory because they only target a certain type of data or are limited to a certain amount of data.
D'autres solutions de l'art antérieur permettent à l'utilisateur de copier ses données sur un autre appareil, comme par exemple sur un autre terminal ou sur un disque dur externe. Other solutions of the prior art allow the user to copy his data to another device, such as for example on another terminal or on an external hard disk.
Ces solutions ne sont pas optimales car elles nécessitent la manipulation d'un autre dispositif ainsi qu'une intervention de la part de l'utilisateur.  These solutions are not optimal because they require the manipulation of another device as well as an intervention on the part of the user.
Ensuite, la plupart de ces terminaux mobiles peuvent être synchronisés avec un micro-ordinateur, notamment via un câble et l'installation d'un logiciel spécifique sur le micro-ordinateur. Then, most of these mobile terminals can be synchronized with a microcomputer, including via a cable and the installation of specific software on the microcomputer.
De la même manière que précédemment, la restauration des données n'est possible que depuis le dispositif, dans ce cas un micro-ordinateur, avec lequel la synchronisation a été effectuée.  In the same way as before, the restoration of the data is only possible from the device, in this case a microcomputer, with which synchronization has been performed.
Enfin, diverses solutions permettent à l'utilisateur de synchroniser certaines de ses données avec un espace de stockage distant. Finally, various solutions allow the user to synchronize some of his data with a remote storage space.
Ces dernières solutions présentent aussi des inconvénients. D'une part, les données synchronisées sont rattachées à un appareil unique et il n'est généralement pas prévu de pouvoir les transférer facilement depuis l 'espace de stockage vers un autre appareil. These latter solutions also have disadvantages. On the one hand, the synchronized data is attached to a single device and it is not generally expected to be able to easily transfer from the storage space to another device.
De plus, la taille de l 'espace de stockage alloué à chaque appareil est limité, et l 'utilisateur doit prendre en charge l 'organisation et la gestion des données transférées sur l 'espace de stockage.  In addition, the size of the storage space allocated to each device is limited, and the user must support the organization and management of the data transferred to the storage space.
D'autre part, la plupart de ces solutions de stockage à distance ne prévoient volontairement pas de transfert sécurisé et n'assurent aucune confidentialité, ce qui permet aux sociétés offrant ce service d'éviter toute responsabilité en cas de perte ou de vol des données contenues dans l 'espace de stockage, parfois même dans le cas d'une défaillance de leurs propres moyens de stockage.  On the other hand, most of these remote storage solutions do not voluntarily provide secure transfer and do not provide confidentiality, which allows companies offering this service to avoid any liability in case of loss or theft of data. contained in the storage space, sometimes even in the event of a failure of their own storage facilities.
En conclusion, aucune des solutions existantes ne s'apparente à un procédé permettant une sauvegarde automatique, c'est à dire sans déclenchement par l 'utilisateur ou par une action de l' utilisateur visant à relier l 'appareil à un autre dispositif, de l ' intégralité des données contenues dans l 'appareil ainsi qu' une restauration desdites données sur un autre appareil en cas de perte ou de vol. Aussi, c'est un objectif de la présente invention de pallier les inconvénients de ces diverses méthodes de l'art antérieur en proposant un procédé de sauvegarde de données contenues dans un terminal communiquant portable, tel un Smartphone®, permettant d'assurer un transfert sécurisé, un stockage confidentiel, et une gestion optimisée et automatisée de l ' intégralité desdites données sur un espace de stockage distant, tout en ne nécessitant pas la manipulation d'un autre dispositif extérieur ou un déclenchement par une action de l' utilisateur. In conclusion, none of the existing solutions is similar to a method allowing automatic backup, ie without triggering by the user or by an action of the user to connect the device to another device, from all the data contained in the device as well as a restoration of said data on another device in case of loss or theft. Also, it is an object of the present invention to overcome the disadvantages of these various methods of the prior art by providing a method of saving data contained in a portable communicating terminal, such as a Smartphone®, to ensure a transfer secure, confidential storage, and optimized and automated management of all of said data on a remote storage space, while not requiring manipulation of another external device or triggering by a user action.
Un autre objectif de la présente invention est de fournir un procédé permettant la sauvegarde de données partagées entre plusieurs terminaux. Another object of the present invention is to provide a method for saving data shared between several terminals.
Bien entendu, le procédé de sauvegarde selon l ' invention prévoit aussi la possibilité de restaurer lesdites données sur un ou plusieurs autres terminaux. A cet effet, l ' invention a pour objet un procédé de sauvegarde de données contenues dans un terminal communiquant portable, ledit terminal comprenant au moins des moyens de traitement desdites données, des moyens d'alimentation, des moyens de mémorisation des différents types de données, des moyens d'affichage, une interface utilisateur, et des moyens de connexion permettant de relier directement ou indirectement ledit le terminal à un réseau public tel qu'Internet, un programme de sauvegarde étant installé et exécuté par ledit terminal, lesdites données mémorisées dans le terminal prenant la forme de différents fichiers sous différents formats, ledit procédé étant caractérisé en ce qu'il prévoit une sauvegarde en ligne d'au moins un fichier sélectionné par l'utilisateur dudit terminal.

The operation of said hardware elements is coordinated by an operating system to which can be added, simultaneously or later, various applications or programs.
Aussi, pour sa mise en oeuvre, le procédé de sauvegarde selon l'invention prévoit l'installation et l'exécution d'un programme de sauvegarde adapté, notamment grâce à la présentation de son interface, à chaque système d'exploitation, par exemple Windows Mobile®, Linux®, Symbian®, Android®, Palm OS®, de chaque type de terminal, notamment Windows Phone®, iPhone®, Gphone®, PDA ou autre. Avantageusement, le cœur dudit programme de sauvegarde peut être sensiblement commun à tous les types de terminal et à tous les types de système d'exploitation.  Also, for its implementation, the backup method according to the invention provides for the installation and execution of a suitable backup program, in particular by the presentation of its interface, to each operating system, for example Windows Mobile®, Linux®, Symbian®, Android®, Palm OS®, each type of terminal, including Windows Phone®, iPhone®, Gphone®, PDA or other. Advantageously, the heart of said backup program can be substantially common to all types of terminal and all types of operating system.
L'ensemble de ces différents éléments, matériel et logiciel, créent et utilisent différents types de données mémorisées dans le terminal 10 sous la forme de différents fichiers F sous différents formats, les formats desdits fichiers F variant notamment d'une application à une autre ou d'un système d'exploitation à un autre.  All of these different elements, hardware and software, create and use different types of data stored in the terminal 10 in the form of different files F in different formats, the formats of said files F varying in particular from one application to another or from one operating system to another.
Ainsi, et de manière non exhaustive, il peut être intéressant de sauvegarder des fichiers système, notamment ceux du registre, des fichiers relatifs à la configuration du terminal choisie par son utilisateur, des fichiers contact, notamment en format vCard, sous la forme de cartes de visite électroniques rassemblant différents renseignements relatifs à une personne, ou sous la forme de carnets d'adresses regroupant des informations relatives à plusieurs personnes, des fichiers calendrier, notamment en format vCal, correspondant à un ou plusieurs événements notés dans un agenda électronique, des fichiers tâche de format généralement propre à chaque système d'exploitation, divers fichiers multimédias prenant de multiples formats, etc. Le procédé selon l'invention prévoit la possibilité d'effectuer une sauvegarde en ligne d'au moins un fichier F, ou de l'intégralité de ces différents fichiers de différents formats contenus dans chaque type de terminal. Thus, and in a non-exhaustive manner, it may be advantageous to save system files, in particular those of the register, files relating to the configuration of the terminal chosen by its user, contact files, especially in vCard format, in the form of cards. electronic information gathering information relating to a person, or in the form of address books containing information relating to several people, calendar files, especially in vCal format, corresponding to one or more events noted in an electronic calendar, task files in a format that is generally specific to each operating system, various multimedia files taking multiple formats, etc. The method according to the invention provides the possibility of performing an online backup of at least one file F, or all of these different files of different formats contained in each type of terminal.
A cet effet, le procédé de sauvegarde selon l'invention prévoit que les programmes de sauvegarde adaptés à chaque type de terminal, ou de système d'exploitation, utilisent un protocole de communication commun avec au moins un premier centre d'hébergement 50 via le réseau public Internet 38. For this purpose, the backup method according to the invention provides that the backup programs adapted to each type of terminal, or operating system, use a common communication protocol with at least a first hosting center 50 via the public Internet network 38.
Afin de sécuriser les transferts de données, ledit protocole commun est spécifique au procédé selon l ' invention. In order to secure data transfers, said common protocol is specific to the method according to the invention.
Avantageusement, au moins un deuxième centre d'hébergement redondant 52 peut être prévu pour parer aux éventuelles défaillances dudit premier centre 50, ledit deuxième centre redondant 52 étant de préférence situé dans un autre lieu géographique. Advantageously, at least a second redundant hosting center 52 may be provided to counter any failures of said first center 50, said second redundant center 52 being preferably located in another geographical location.
De plus, lesdits centres d'hébergement peuvent aussi être reliés par une double connexion audit réseau public Internet 38, et, dans chacun desdits centres 50 et In addition, said hosting centers may also be connected by a dual connection to said public Internet network 38, and in each of said centers 50 and
52, les serveurs d'hébergement sont protégés physiquement et électriquement.52, the hosting servers are physically and electrically protected.
Afin de pouvoir accéder à la sauvegarde du contenu d'au moins un terminal 10 autrement que depuis ledit terminal, par exemple en cas de perte, de vol ou de destruction, l'invention prévoit un dispositif de supervision 54, notamment un micro-ordinateur, permettant à l'utilisateur d'accéder aux données sauvegardées dans le centre d'hébergement (50,52) par l'intermédiaire du réseau publicIn order to be able to access the backup of the content of at least one terminal 10 other than from said terminal, for example in the event of loss, theft or destruction, the invention provides a supervision device 54, in particular a microcomputer , allowing the user to access the data saved in the hosting center (50,52) via the public network
Internet 38. Internet 38.
Bien entendu, le micro-ordinateur 28 de l'utilisateur peut aussi être utilisé comme dispositif de supervision 54.  Of course, the microcomputer 28 of the user can also be used as a supervision device 54.
Le procédé de sauvegarde, ses différentes étapes, et son utilisation vont maintenant être décrits. The backup method, its different steps, and its use will now be described.
Tout d'abord, la première étape suivie par l'utilisateur est d'installer le programme de sauvegarde sur au moins un terminal 10. Par la suite, grâce à l'interface dudit programme de sauvegarde, l'utilisateur sélectionne une partie du contenu, soit au moins un fichier F, dudit terminal qu'il souhaite sauvegarder. First, the first step followed by the user is to install the backup program on at least one terminal 10. Subsequently, through the interface of said backup program, the user selects a part of the content, at least one F file, said terminal he wants to save.
Plus précisément, l'utilisateur sélectionne au moins un fichier F enregistré dans les moyens de mémorisation 16 d'au moins un terminal 10 dans lequel est installé le programme de sauvegarde.  More precisely, the user selects at least one file F recorded in the storage means 16 of at least one terminal 10 in which the backup program is installed.
Ensuite, le procédé selon l'invention prévoit un déclenchement de la sauvegarde manuellement par l'utilisateur, ou automatiquement par une programmation selon une fréquence donnée : par exemple plusieurs fois par jour à intervalles réguliers.  Then, the method according to the invention provides a triggering of the backup manually by the user, or automatically by programming at a given frequency: for example several times a day at regular intervals.
Bien entendu, dans le cas où le terminal 10 était éteint ou en veille au moment prévu pour effectuer la sauvegarde, le programme de sauvegarde déclenche une sauvegarde dès la mise en marche ou la sortie de veille dudit terminal 10.  Of course, in the case where the terminal 10 was off or on standby at the scheduled time to perform the backup, the backup program triggers a backup from the start or wakeful output of said terminal 10.
Qu'elle soit déclenchée manuellement ou automatiquement, la réalisation d'une sauvegarde est dépendante de la connexion du terminal 10 au réseau public Internet 38. Whether triggered manually or automatically, performing a backup is dependent on the connection of the terminal 10 to the public Internet network 38.
Ainsi, une sauvegarde n'ayant pu être effectuée au moment prévu en raison de l ' impossibilité d'accéder audit réseau 38 sera déclenchée automatiquement dès le retour de ladite connexion.  Thus, a backup could not be performed at the scheduled time due to the inability to access said network 38 will be triggered automatically upon return of said connection.
Lorsque la communication avec un centre d'hébergement (50,52) est possible et qu'une sauvegarde a été déclenchée, le programme de sauvegarde cherche à se connecter audit centre (50,52). When communication with a hosting center (50,52) is possible and a backup has been triggered, the backup program seeks to connect to said center (50,52).
A cet effet, et en plus du protocole de communication commun et particulier utilisé par l'invention, pour autoriser cette connexion, le procédé de sauvegarde prévoit l'authentif ication d'un terminal 10 auprès d'un centre (50,52) par au moins un nom d'identifiant, ou « Login », et un mot de passe reliés à la licence d'utilisation du programme de sauvegarde, ainsi que par le numéro de série unique, aussi appelé IMEI, du terminal 10. Ensuite, une fois le terminal 10 reconnu par le centre d'hébergement (50,52), le procédé selon l'invention prévoit de seulement transmettre des informations d'identification de chaque fichier sélectionné du terminal 10 audit centre (50,52). For this purpose, and in addition to the common and particular communication protocol used by the invention, to authorize this connection, the backup method provides the authentication of a terminal 10 to a center (50, 52) by at least one username, or "Login", and a password related to the license to use the backup program, as well as the unique serial number, also called IMEI, of the terminal 10. Then, once the terminal 10 recognized by the hosting center (50,52), the method according to the invention provides only to transmit identification information of each selected file from the terminal 10 to said center (50,52).
Lesdites informations d'identification sont au moins relatives au nom, à la taille, au type dudit fichier, c'est-à-dire à son format, à sa date de création ou de modification, et/ou à sa signature, de préférence obtenue par un encryptage, ou chiffrement, à l'aide d'une fonction dite SHA1. Said identification information is at least relative to the name, size, type of said file, that is to say, its format, the date of creation or modification, and / or its signature, preferably obtained by encryption, or encryption, using a function called SHA1.
Au moins une information d'identification, notamment sa signature, est utilisée par le centre d'hébergement pour contrôler l'intégrité du fichier et vérifier si il contient déjà un fichier identique, ledit fichier ayant pu être modifié alors qu'il a déjà été enregistré dans une version précédente lors d'une sauvegarde antérieure.  At least one identifying information, including its signature, is used by the hosting center to check the integrity of the file and to check if it already contains an identical file, said file having been modified while it has already been saved in a previous version during a previous backup.
Ainsi, les transferts inutiles et la duplication des fichiers sont évités, et un gain d'espace de stockage est obtenu dans les serveurs du centre d'hébergement. Thus, unnecessary transfers and duplication of files are avoided, and a gain of storage space is obtained in the servers of the hosting center.
D'une manière générale, le procédé de sauvegarde selon l'invention prévoit l'encryptage de tous les fichiers F transmis entre un terminal 10 et un centre d'hébergement (50,52), seul l'utilisateur dudit terminal 10 disposant de la clé pour visualiser les données contenues dans lesdits fichiers encryptés. In general, the backup method according to the invention provides for the encryption of all the files F transmitted between a terminal 10 and a hosting center (50,52), only the user of said terminal 10 having the key to view the data contained in said encrypted files.
Ainsi, en encryptant les fichiers directement dans le terminal 10, le programme de sauvegarde permet des transferts sécurisés du contenu du terminal. Thus, by encrypting the files directly in the terminal 10, the backup program allows secure transfers of the contents of the terminal.
Avantageusement, cela permet aussi de supprimer la responsabilité de l'hébergeur vis-à-vis des contenus des terminaux de ses clients hébergés sur ses serveurs. Advantageously, this also eliminates the responsibility of the host vis-à-vis the content of the terminals of its customers hosted on its servers.
De préférence, le procédé selon l' invention prévoit d'effectuer une sauvegarde incrémentale desdits fichiers F. A titre indicatif, ladite sauvegarde incrémentale des fichiers F peut être réalisée comme indiqué dans la demande européenne de brevet du même demandeur et publiée sous la référence EP-2.110.747. Preferably, the method according to the invention provides for an incremental backup of said files F. As an indication, said incremental backup F files can be performed as indicated in the European patent application of the same applicant and published under the reference EP-2.110.747.
Ainsi, lors de la réalisation d' une sauvegarde, seuls les fichiers F non présents sur les serveurs du centre d' hébergement (50,52) ou ayant été modifiés depuis la dernière sauvegarde sont transférés et enregistrés sur lesdits serveurs.  Thus, when performing a backup, only F files not present on the servers of the hosting center (50,52) or having been modified since the last backup are transferred and stored on said servers.
Ladite sauvegarde incrémentale génère une base de données regroupant toutes les versions successives des différents fichiers F enregistrées lors de sauvegardes antérieures depuis une date donnée, de préférence depuis leur création, jusqu'à la dernière sauvegarde. Said incremental backup generates a database grouping all the successive versions of the different files F recorded during previous backups since a given date, preferably since their creation, until the last backup.
Avantageusement, ladite sauvegarde incrémentale limite la quantité de données transférées lors d'une sauvegarde.  Advantageously, said incremental backup limits the amount of data transferred during a backup.
Grâce à ladite base de données ainsi créée par la sauvegarde incrémentale, le procédé de sauvegarde selon l ' invention permet la restauration d'au moins un fichier F dans une version antérieure, ou même de l ' intégralité du contenu du terminal 10 à la date de toute sauvegarde ultérieure.  Thanks to said database thus created by the incremental backup, the backup method according to the invention allows the restoration of at least one file F in an earlier version, or even of all the contents of the terminal 10 at the date any subsequent backup.
Le procédé selon l ' invention prévoit la possibilité d'effectuer une restauration d'au moins un fichier F dans une version antérieure vers le terminal 10 utilisé, ou vers tout nouveau terminal 10 de remplacement, dans la limite de compatibilité du format dudit fichier, cette dernière possibilité étant particulièrement intéressante en cas de vol, de perte, ou de destruction du terminal 10 utilisé initialement.  The method according to the invention provides the possibility of performing a restoration of at least one file F in an earlier version to the terminal 10 used, or to any new replacement terminal 10, within the limit of compatibility of the format of said file, the latter possibility being particularly interesting in case of theft, loss, or destruction of the terminal 10 used initially.
Ladite restauration peut être menée depuis le terminal 10 utilisé, depuis tout nouveau terminal 10 de remplacement, ainsi que depuis le dispositif de supervision 54, dans la mesure où le programme de sauvegarde est installé sur ledit terminal.  Said restoration can be carried out from the terminal 10 used, from any new replacement terminal 10, as well as from the supervision device 54, insofar as the backup program is installed on said terminal.
Lors d'une restauration sur le terminal 10 utilisé, ou sur un terminal de remplacement, le procédé prévoit au préalable l'authentification dudit terminal, respectivement de l'ancien et du nouveau terminal, par le centre d' hébergement (50,52) à l 'aide d'au moins un nom d'identifiant et d'un mot de passe reliés à la licence d'utilisation du programme de sauvegarde, ainsi qu'à l 'aide du numéro de série unique, aussi appelé IMEI, du ou des terminaux. During a restoration on the terminal 10 used, or on a replacement terminal, the method provides for prior authentication of said terminal, of the old and the new terminal, respectively, by the hosting center (50,52) using at least one username and password related to the license to use the program. backup, as well as the unique serial number, also called IMEI, of the terminal (s).
Lors d'une demande de restauration d'au moins un fichier F, au moins une partie des informations d'identification dudit fichier sont transmises au centre d'hébergement pour lui permettre de retrouver la version dudit fichier à restaurer. During a request to restore at least one file F, at least a portion of the identification information of said file is transmitted to the hosting center to enable it to find the version of said file to be restored.
Ensuite, si la version dudit fichier est retrouvée dans la base de données correspondant audit terminal, une proposition de restauration d' une ou plusieurs versions dudit fichier est transmise à l 'utilisateur par l' intermédiaire de l'interface de son terminal 10, d'un nouveau terminal, ou du dispositif de supervision 54.  Then, if the version of said file is found in the database corresponding to said terminal, a proposal for restoring one or more versions of said file is transmitted to the user via the interface of his terminal 10, d. a new terminal, or supervisory device 54.
Si la proposition de restauration est acceptée, le centre d' hébergement (50,52) transmet la version choisie dudit fichier au terminal et met à jour la base de données de la sauvegarde.  If the restoration proposal is accepted, the hosting center (50,52) transmits the selected version of said file to the terminal and updates the backup database.
En cas de vol, de perte ou de destruction du terminal 10 utilisé, et avant toute restauration d'au moins un fichier sur un nouveau terminal, il est nécessaire que l 'utilisateur déclare au préalable ladite perte ou ledit vol auprès du cen re d' hébergement, ladite déclaration pouvant être effectuée depuis le nouveau terminal ou depuis le dispositif de supervision 54.  In case of theft, loss or destruction of the terminal 10 used, and before any restoration of at least one file on a new terminal, it is necessary for the user to declare said loss or theft beforehand to the central d accommodation, said declaration can be made from the new terminal or from the supervisory device 54.
Cette déclaration consiste de préférence à indiquer au centre d'hébergement le numéro de série unique, aussi appelé IMEI, du terminal volé ou perdu.  This declaration preferably consists of indicating to the hosting center the unique serial number, also called IMEI, of the stolen or lost terminal.
Toujours dans le cas de vol ou de perte du terminal 10 utilisé, le procédé selon l ' invention prévoit la possibilité de détruire les données qu' il contient. Also in the case of theft or loss of the terminal 10 used, the method according to the invention provides the possibility of destroying the data it contains.
De la même manière que pour une restauration, avant toute demande de destruction d'au moins un fichier, le procédé nécessite au préalable une déclaration de ladite perte ou dudit vol auprès du centre d' hébergement , de préférence en indiquant le numéro de série unique, aussi appelé IMEI, du terminal volé ou perdu. In the same way as for a restoration, before any request to destroy at least one file, the process first requires a declaration of said loss or theft at the accommodation center, the preferably by specifying the unique serial number, also called IMEI, of the stolen or lost terminal.
Suite à ladite déclaration, la demande de destruction d'au moins un fichier est acceptée seulement après authentif ication de l'ancien et du nouveau terminal par le centre d' hébergement (50,52) à l 'aide d'au moins un nom d'identifiant et d' un mot de passe reliés à la licence d'utilisation du programme de sauvegarde, ainsi qu'à l'aide du numéro de série unique, aussi appelé IMEI, desdits terminaux. Avantageusement, postérieurement à une déclaration de vol ou de perte du terminal utilisé auprès du centre d' hébergement (50,52) et lors du déclenchement d'une sauvegarde, le procédé prévoit une destruction automatique par le programme de sauvegarde des fichiers contenus dans ledit terminal si le ledit terminal est identifié comme volé ou perdu par le centre d' hébergement.  Following said declaration, the request to destroy at least one file is accepted only after authentication of the old and new terminal by the hosting center (50,52) using at least one name. identifier and password related to the license to use the backup program, and using the unique serial number, also called IMEI, said terminals. Advantageously, subsequent to a declaration of theft or loss of the terminal used at the hosting center (50,52) and when initiating a backup, the method provides for an automatic destruction by the backup program files contained in said terminal if said terminal is identified as stolen or lost by the hosting center.
Selon une autre caractéristique importante de l ' invention, le procédé prévoit la possibilité de partager la sauvegarde d'au moins un fichier F utilisé par plusieurs terminaux 10, et donc par plusieurs personnes.  According to another important feature of the invention, the method provides the possibility of sharing the backup of at least one file F used by several terminals 10, and therefore by several people.
Lors d'une telle sauvegarde partagée, le centre d' hébergement vérifie tout d'abord si la base de données ne comporte pas déjà une version dudit fichier F contenant des données identiques à l 'aide d'au moins une information d' identification, notamment la taille, dudit fichier F.  During such a shared backup, the hosting center first checks whether the database does not already include a version of said file F containing identical data using at least one identification information, especially the size, of said file F.
Ensuite, si il identifie un fichier F dont les données ont été modifiées et donc différent, le centre d' hébergement enregistre dans la base de données une nouvelle version dudit fichier, chaque version dudit fichier étant rattachée au terminal, et donc à la personne qui l'a modifié, par au moins une information d' identification, notamment sa signature de préférence obtenue par un encryptage, ou chiffrement, à l'aide d'une fonction dite SHA1.  Then, if it identifies an F file whose data have been modified and therefore different, the hosting center records in the database a new version of said file, each version of said file being attached to the terminal, and therefore to the person who has modified it, by at least one identification information, especially its signature preferably obtained by encryption or encryption, using a function called SHA1.
Selon un premier exemple de sauvegarde partagée, il peut s'agir d' un fichier tarif regroupant une liste de plusieurs produits et leurs tarifs respectifs, ledit fichier étant susceptible d'être modifié par une équipe de plusieurs commerciaux équipés de terminaux 10 sur chacun desquels est installé le programme de sauvegarde. According to a first example of shared backup, it may be a tariff file grouping a list of several products and their respective tariffs, said file being likely to be modified by a team of several commercial equipped with terminals 10 on each of which is installed the backup program.
Selon un deuxième exemple de sauvegarde partagée, il peut s'agir du partage entre plusieurs membres d'une entreprise d'une liste de contacts, notamment sous la forme de plusieurs cartes de visite électroniques sous format vCard. Ainsi, chaque fichier correspondant à une carte de visite peut comporter une signature différente, notamment obtenue à l 'aide d'une fonction dite SHA1. Ensuite, lors d'une sauvegarde, chaque terminal transmet la signature des différentes carte de visite de sa liste de contacts, et le serveur contrôle lesdites signatures pour identifier les cartes de visite que sa base de données ne répertorie pas et pour enregistrer les nouvelles cartes de visite.  According to a second example of shared backup, it can be sharing between several members of an enterprise of a contact list, especially in the form of several electronic business cards in vCard format. Thus, each file corresponding to a business card can have a different signature, in particular obtained using a function called SHA1. Then, during a backup, each terminal transmits the signature of the various business cards in its contact list, and the server checks the signatures to identify the business cards that its database does not list and to register the new cards visit.
De préférence, lors des transferts de données entre un terminal et un centre d' hébergement, lesdites données sont cryptées pour assurer la confidentialité. Dans le but d'accélérer les transferts de données, tant lors d'une sauvegarde que lors d'une restauration des fichiers, lesdites données sont compressées. De préférence, les algorithmes utilisés pour l'encryptage et la compression des fichiers sont exportables ou adaptables selon les pays d' utilisation du terminal. Pour finir, on constate que le procédé de sauvegarde selon l'invention permet effectivement d'assurer la sécurisation des transferts et la confidentialité du stockage du contenu d'un terminal grâce au chiffrement des données. Preferably, during data transfers between a terminal and a hosting center, said data is encrypted to ensure confidentiality. In order to accelerate data transfers, both during a backup and during a file restoration, said data is compressed. Preferably, the algorithms used for the encryption and the compression of the files are exportable or adaptable according to the countries of use of the terminal. Finally, it is noted that the backup method according to the invention makes it possible to ensure the secure transfer and confidentiality of the storage of the content of a terminal through the encryption of data.
De plus, la sauvegarde incrémentielle permet bien une gestion optimisée et automatisée de l'enregistrement des fichiers, notamment de l ' intégralité desdits fichiers, contenus dans un terminal de type Smartphone® ou PDA®. Moreover, the incremental backup makes it possible to optimize and automate the recording of the files, in particular all the said files, contained in a terminal of the Smartphone® or PDA® type.
Enfin, ladite sauvegarde incrémentielle associée à la signature desdits fichiers permet effectivement la sauvegarde dans une base de données distante d'au moins un fichier partagé entre plusieurs terminaux et modifié par plusieurs utilisateurs. Finally, said incremental backup associated with the signature of said files actually allows the backup in a remote database of at least one file shared between several terminals and modified by several users.
