| Outline of Final Research Achievements |
Since a mobile terminal is always carried and used in various situations, assumed threats in a use of the mobile terminal are also changed depending on the context. Therefore, a user authentication in mobile terminals, as a basic security function of them, should be flexible according to the situations and threats.
In this research，We worked on developing user authentication systems that could contribute to the above goal. The research results are as follows.
1) Image-based user authentication system that can flexibly configure a providable security level without changing a user credential, 2) a user authentication method with a time-limited password that is defined using a "time-period based rule" for life-log based data, 3) credential input schemes that could make it hard to steal a credential data by a shoulder surfing attack by using vibration information and pressure input, 4) Proposal a scheme of an availability control of a user authentication by users themselves.
