METHOD FOR PREVENTING INFORMATION LEAKAGE OF HOST APPARATUS

摘要

PURPOSE: A method for blocking information leakage through a synchronizing program of a host device is provided to control data transmission by blocking a virtual port of a synchronizing program. CONSTITUTION: A portable storage medium is connected to a host device(210). The hooking of a system call operates(230). The system call is delivered from an application of the host device to a kernel. It is determined whether the system call is transmitted to the portable storage medium through a virtual port. The transmission of the system call is blocked according to a determination result(270).
