Abstract EN

User authentication is a process in which a user of a system proves his/her identity to acquire access permission.

An effective user authentication method should be both secure and usable.

In an attempt to achieve these two objectives, Bianchi et al.

recently proposed novel unimodal PIN-entry methods that use either audio or vibration cues.

This paper analyzes the security of their method, in particular, the vibration version of one of their proposals, Timelock.

A probabilistic analysis and real attack experiment reveal that the security level guaranteed by Timelock is lower than that claimed in Bianchi et al.’s paper.

As countermeasures to this problem, three PIN-entry methods are proposed and a usability study is performed.

According to the result of this study, a simple modification may improve the security significantly while retaining the design philosophy of unimodal systems.

In addition, the proposed methods address the PIN compatibility issue of Timelock and they can be used to enter a legacy numerical PIN without any change in the PIN.
