| Abstract(in English) | Because of the problems lately highlighted in password authentication, the picture-authentication system (using pictures of individuals for identification) has been suggested. This system requires low cognitive load compared with conventional person authentication systems and has potential for introducing the "the human-friendly authentication," required in the modem society. However, some issues that arise in constructing a safe and easy-to-use picture-authentication system are yet to be resolved. For example, effects of repetition on recognition tests, i. e., use of the same pictures repeatedly as dummies, and differences between autobiographical and non-personal pictures. Long-term recognition experiments were conducted using two types of pictures : autobiographical (AB, those brought by the participants) and self-selected (SS, those chosen from a given set of pictures by the participants). Results of two recognition tests (three or six-week delay from learning) showed that when AB was used, recognition performance was slightly higher and confidence rates were much better than when SS was used. In the second test, both AB and SS showed large improvements in performance. However, recognition performance decreased when the same dummies from previous tests were used compared to when the new dummies were used. |
