摘要

传统的文本密码认证被广泛用于计算资源的访问。年龄较大的用户发现，使用强文本密码所需要的认知努力和手动灵巧技能具有挑战性。我们设计并评估了基于触摸屏选择的图形密码系统，该系统将熟悉的面部图像随机嵌入不熟悉但相似的图像中。在我们的可用性研究中，老年用户的召回率为97%，密码熵优于短pin，认证时间与短文本密码相当。

Graphical passwords for older computer users

Traditional text password authentication is widely used to gain access to computing resources. Older users find the cognitive effort, and manual dexterity skills needed to use strong text passwords challenging. We designed and evaluated our Graphical Password system based on touchscreen selection of familiar facial images embedded randomly among unfamiliar, yet similar images. In our usability study, older users demonstrated a recall rate of 97%, password entropy superior to short PINs, and authentication time comparable to short text passwords.
