PROBLEM TO BE SOLVED: To construct an unauthorized approach prevention type computer system for preliminarily preventing any damage due to all unauthorized programs including virus by checking any unregistered program in a collation process in the preceding stage of execution. SOLUTION: Instead of monitoring and disinfection of any conventional virus or unauthorized program by the registration of a virus pattern, the registration of the pattern data of a file whose access is permitted in a collation server and establishment of an automatic collation system to registration data by a collation client in performing access to the file make it possible to secure propriety of the file by the collation with the preliminarily registered pattern data each time the file is accessed, and to prevent the approach of any virus or unauthorized program without making it necessary to recognize the type or feature of the virus or unauthorized program, and to secure safety of a computer system.
