摘要

Disclosed are a system for providing an application by using a cloud virtual file, a cloud server, a method for providing an application, a service server, a service method, a mobile communication terminal, and a method for executing an application. The system for providing an application by using a cloud virtual file according to the present invention comprises: a cloud server which stores files adapted to be movable to an external memory of a mobile communication terminal and adapted to be selected among files constituting at least one application, in a common service region of a cloud storage; and a service server which receives device identification information from the mobile communication terminal, which encrypts at least one of the files stored in the common service region of the cloud server based on the received device identification information, which generates a disk image file based on the encrypted file, and which copies the generated disk image file onto a personal cloud storage region of the cloud server corresponding to the mobile communication terminal. In this case, the mobile communication terminal mounts the file encrypted by the service server, and directly accesses the personal cloud storage region of the cloud server based on the device identification information.;COPYRIGHT KIPO 2017
