Abstract

現在,銀行やクレジットカード等に用いられている4桁の暗証番号によるユーザ認証の脅威についてまとめ,これまで提案されてきた対策手法について長所,短所の考察を交えて紹介する.これらの対策手法の中から,利便性とセキュリティ強度の兼ね合いを考慮した上で,入力位置情報を付加したパスワード認証方式を実装し,その操作性について評価する.その結果,いくつか問題点が明らかになったため,その改善策を提案し,実装と評価を行い,利便性とセキュリティ強度が向上されることを示す.We summarize dangers on authentication system used at a bank or credit card, and introduce several measures against them. We implement and evaluate one of these measures, authentication system using input location information, in consideration of the balance between security intensity and usability. Consequently, some problems became clear. In this paper, we propose the authentication system that can improve these problem. By using our authentication system, it is possible to improve security intensity without spoiling usability.
