[PROBLEMS] To prevent information leak from a server device without lowering user-friendliness. [MEANS FOR SOLVING PROBLEMS] Provided is a system including a server device operating an application program and a client device communicating with a server device for enabling a user to use the application program. The server device includes: an output detection unit for detecting an output process as a process for outputting data from an application program to a shared region; and an output control device for storing in the shared region the instruction information indicating the acquisition method for an authorized client device to acquire the output data instead of the output data outputted from the application program according to detection of the output process. The client device includes: a read detection unit for detecting a read process as a process for reading data from the shared region and a read control unit for acquiring output data by the acquisition method specified by the instruction information.

L~objet de l~invention est d~empêcher la fuite d~informations d~un dispositif serveur sans diminuer l~ergonomie. L~invention concerne un système incluant un dispositif serveur exécutant un programme d~application et un dispositif client communiquant avec le dispositif serveur pour permettre à l~utilisateur d~utiliser le programme d~application. Le dispositif serveur comprend : une unité de détection de sortie pour détecter un processus de sortie en tant que processus de sortie de données d~un programme d~application vers une zone partagée ; et un dispositif de commande de sortie pour stocker dans la zone partagée les informations d~instruction indiquant la méthode d~acquisition pour qu~un dispositif client autorisé acquière les données de sortie au lieu des données de sortie fournies par le programme d~application selon la détection du processus de sortie. Le dispositif client comprend : une unité de détection de lecture pour détecter un processus de lecture en tant que processus de lecture de données de la zone partagée et une unité de commande de lecture pour acquérir des données de sortie par la méthode d~acquisition spécifiée par les informations d~instruction.
