These terminals prevent leakage of information with user authentication using input on touch-panel, especially using pattern lock over Android. However, this authentication method has a problem of leakage of pass-pattern easily with shoulder surfing. Against this problem, Higashikawa et al. proposed a pattern lock method against shoulder surfing with memorizing a random digit string temporarily and entering it. However, the above method has a problem of deterioration in convenience for a user because of increasing user's memory and complication of input pattern. In this paper, we propose a improved method with modification in the input pass-pattern because of improving convenience and more protection against shoulder surfing. Furthermore, we show evaluation of usability and safety in our method. By using our proposal, safer user authentication method than pattern lock can be realized on existing mobile terminals.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"188","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"179","bibliographicIssueDates":{"bibliographicIssueDate":"2018-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"59"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:52:29.837696+00:00","id":185367,"links":{}}
