Especially password guessing attack, such as dictionary attack, is a major methods in this type of attack. To counter this type of attack, we try to apply ``a personal difference in information recognition'' to a user authentication. This makes password guessing more hard because attackers have to guess a victim's secret more than one times. In this paper, we use a deformed portrait as a secret in a user authentication.  In this system, attackers have to succeed two guesses in order to impersonate a victim: 1) Whose face is a secret?, 2) How a face is illustrated to a portrait? We implemented a prototype authentication system and conducted a user study to evaluate memorability of a secret and security level to a guessing attack.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"872","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2012論文集"}],"bibliographicPageStart":"865","bibliographicIssueDates":{"bibliographicIssueDate":"2012-10-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2012"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
