• the present invention relates to a method for providing a target application on a terminal.
• Native applications are known, running through the operating system of the terminal, forming a link between such applications and the hardware elements of the terminal, such an operating system being for example Windows Vista or Linux.
• a method of providing such applications may include a step of downloading the native application from a server followed by a step of installing this application on the user's terminal. During this step, the various files constituting the application are notably stored in the memory of the terminal and a path to the application is created.
• Internet applications are also known that run using an internet browser, such as Internet Explorer, Mozilla Firefox or Google Chrome, for example, and a virtual machine, such as Java, Javascript or Flash, which allows the user to access the Internet. execution of the internet application while the elements constituting it are not stored on the terminal. The elements constituting this one are stored largely on an external server to which the terminal can access by means of an Internet network. To use this application, the terminal must always communicate with the server storing these elements.
• the method of providing such an application therefore generally comprises a step of accessing the server, accompanied by user authentication.
• the invention makes it possible to provide an alternative to the above-mentioned internet applications, by providing a user-friendly method of provisioning, and this method being applicable for all types of already existing applications, without substantially modifying them. .
• the subject of the invention is a method for making a target application available on a terminal, comprising the following steps: transfer from a server to the terminal of a deployment application, this application being an internet application,
• the deployment application allows the execution of all the steps for the use of the target application without any user intervention, including its transfer. This therefore decreases the number of operations to be performed by the user, or "number of clicks" to obtain access to the target application and therefore increases its interest for the target application.
• the target application on the terminal between two uses is not always justified, the provision of it being very simple.
• This can therefore be stored on the terminal in the memory location of the terminal corresponding to the cache of the browser, and, therefore, be deleted automatically after a predetermined period of time.
• This makes it possible to minimize data transfers during the reuse of the target application, but it is not necessary to perform a specific uninstall operation when the user no longer wishes to use the target application.
• the target application does not unnecessarily occupy the storage space in the terminal.
• the deployment application is an internet application, ie an application that runs through a virtual machine, such as Java, and an internet browser, which allows the user to obtain the application- target without having to download and install previously another application forming the deployment application.
• a deployment application formed by an internet application is also compatible with all operating systems and all browsers and can therefore be universally used. It is also not necessary to update such an application which is updated automatically online.
• the method according to the invention also makes it possible to make available to the user, in a non-binding manner, numerous already existing target applications without needing to modify them in a significant way, or even without having to modify them at all. beforehand.
• the tools to make these available are indeed independent of the target application chosen by the user. These tools also make available many target applications.
• the method may also include one or more of the features of the following list:
• the method comprises a step of execution of an interceptor, triggered by the deployment application, this interceptor being able to intercept at least one request from the target application, the execution of the intercepting interceptor preference in turn that of the target application.
• an interceptor forming a computer program separate from the deployment application, which performs the interceptions in the target application, such an interceptor can then be separate from an internet application and be a native application directly interact with the operating system of the terminal, making it possible to intercepts requests more easily using known techniques
• the method comprises a step of transferring the interceptor from a server, triggered by the deployment application.
• the interceptor is thus transferred to the terminal without the user needing to perform an additional action,
• the method comprises a preliminary step of actuation by a user of the terminal of a link located on a web page,
• the transfer of at least one module of the target application and / or the interceptor is preceded by a verification step performed by the deployment application with the terminal and / or a server.
• the verification step may comprise a step of verifying the access rights of the terminal to the module of the target application.
• the user can have access to the target application only if he has registered with an authority and / or paid for access rights.
• the deployment application allows free access only to a portion of the target application, to enable the user to test the target application.
• This verification step may also include a step of comparing the module to be downloaded and the module possibly stored on the terminal or a comparison of a file name with the file names transferred to the terminal.
• the method comprises at least one step of redirecting the or at least one request to an operating system of the terminal, and / or to the deployment application. These redirection operations are notably performed by the interceptor.
• the method comprises a step of intercepting a query for displaying the target application and modifying this request so that the target application is displayed in a web page, in particular the web page comprising the link.
• the modified query is redirected to the operating system. This avoids opening multiple windows to get the user to get the target application. The user thus benefits from a better comfort of use of the target application. It also makes it possible to integrate the target application with a particular environment, adapted to the user and his needs, for example to improve the aesthetics of the environment presented to the user or to disseminate to the user offers related to his needs while using the target application,
• the method comprises a step of intercepting a request to open a file that does not belong to the base module of the target application and a step of transferring the file from a server to the terminal, this transfer being controlled by the deployment application.
• Some files are transferred to the terminal only when they are requested by the user. For example, if the latter uses a word processor, the drawing module may not be transferred to the terminal during an initial transfer step and then transferred to the terminal only if this module is requested by the user. This optimizes the storage space reserved for the application on the terminal and minimizes the transfer time required for the user to start using the target application,
• the method may also comprise a step in which the action of the target application is controlled according to a link activated on a web page. This allows communication of the target application with its environment.
