PROBLEM TO BE SOLVED: To promote prevention of data theft of an information processor by allowing the user of the information processor to recognize who tries unauthorized use and how often the trial is performed. SOLUTION: A password inputted in 13 is compared with a correct password in 14. When the password is the unauthorized one, it is determined that the password is used in an unauthorized manner. Then a date and an image by a camera at that time are preserved in 15, 16. When a normal user starts an operation afterward and inputs the correct password, it is determined whether the past trial of unauthorized use exists or not in 18, and information at that time is displayed in 19 if exists. Consequently, the normal user recognizes when the unauthorized use is tried, and who tries the unauthorized use. COPYRIGHT: (C)2004,JPO&NCIPI |
