サーバ操作時のキーストローク情報による継続的個人認証

抄録

A general password authentication method can’t prevent unauthorized use by a third party if a system would be hacked (cracked) in some way even once. Therefore, we propose a continuous personal authentication method with keystroke data for server operation which is required at that situation. If server administrators would be requested to input their own password periodically again and again, the users will be too busy to operate system and the burden will increase absolutely. Therefore, it can be said that it is important to use a method of personal authentication that does not require user consciousness. So in this research, in order to alleviate the burden on users and solve security problems, we verify whether personal authentication by self-organizing map is possible using keystrokes during server operation and also evaluate the availability of our proposed method.
