Abstract: PURPOSE: A method for securing document file using a process ID and a storage space ID is provided to protect a certain file from an outside invader by implementing a software security technique which is easily applicable to a personal computer without using an additional device. CONSTITUTION: A file system manager determines whether file handling occurs in an application program(S410). An FSH(file system hook) interrupts a vector of the file-related operation applied from the file system manager to execute it, and then checks whether security is set on the file-related operation or not(S420). It is checked whether the file-related operation is related to a registered file or not(S430). It is checked whether the file-related operation is related to a registered process or not(S440). It is checked whether the file-related operation is generated in a registered hard disk or not(S450). It is checked whether the file-related operation is registered handling or not(S460). If the file-related operation is not contrary to security, a corresponding file system is connected so that the file handling can be processed(S470). If the file-related operation is contrary to the security, a handling error message is output(S480).
