SYSTEM AND METHOD FOR MOBILE DATA LOSS PREVENTION WHICH USES FILE SYSTEM VIRTUALIZATION

摘要

Disclosed are a mobile data loss prevention system and a method thereof. The mobile data loss prevention system according to an embodiment of the present invention comprises a general storage place which is accessed in a general mode and a security mode; a virtual storage place which is not accessed in the general mode and is accessed in the security mode; a management program which designates the general storage place as a reading/writing area in the general mode and designates the general storage place and the virtual storage place as the reading/writing area in the security mode; a fuse which intercepts the file input/output of an application program comprising the management program in the security mode according to a command of the management program and which resets a path as the virtual storage place; and a VFS engine which performs a bridge function between the application program of an application system and the fuse of a kernel system.
