Abstract (in Japanese) (See Japanese page) 
(in English) User accounts may be hijacked carelessly, and system administrators
should detect such hijacked user accounts as soon as possible to eliminate or minimize malicious accesses.
In this study, we propose a method to detect the use of the hijacked
user accounts by focusing on both the autonomous systems number of access source and the time interval of accesses.
We introduce an assumption that authentic users take relatively long time to change or transfer their network systems in access source.
In this paper, this assumption is verified by analyzing the actual
access logs in university information systems.
