Falsification preventing apparatus, falsification preventing method and recording medium therefor

摘要

A monitoring section detects a write instruction to an open directory of a recording section in a control section from a write and read control section. When a falsification detection signal is inputted from the monitoring section to a control section, the control section controls a copy control section to read and copy information stored in backup directories to the open directory. This can prevent the open directory from being falsified. Since falsification is detected by detecting the write instruction, a high storage recording device and a high CPU capability are not required to detect the falsification.
