Zusammenfassung:	PROBLEM TO BE SOLVED: To detect unauthorized entries into an image processor in the image processor. SOLUTION: State transition data which define processing functions of a document processor 104 are enciphered and stored in a data storing device 108 as a state transition file. A log file of access operations to the document processor 104 is compared with the state transition file. If the state transition data in the log file has missing parts compared with the state transition file, the log file is abnormal and invasion is detected. COPYRIGHT: (C)2008,JPO&INPIT
