PROBLEM TO BE SOLVED: To provide an evidence screen storage program capable of rapidly storing an evidence screen at the time of occurrence of an invalid operation made to a computer. SOLUTION: When the computer accepts an operation, whether it is an invalid operation or not is determined in reference to a rule or the like. When the invalid operation is determined, display data displayed on a screen by this operation area acquired by a VRAM or a device context, and stored as evidence data with date or the like in an evidence data storage part. The report of such evidence data or invalidity may be transmitted to a manager through a network. A stopping processing such as stoppage of the operation or disconnection of the network is performed to the invalid operation. COPYRIGHT: (C)2005,JPO&NCIPI
