本文介绍了一种简单的、基于软件的IBM PC键盘监视系统，用于连续分析用户的打字特征，以达到连续认证的目的。通过利用PC键盘接口的电气特性以及对内部系统计时器的修改，可以非常准确地测量触发间隔和持续时间，包括翻转测量。滚动模式，特别是在键入常见的双元音时，可以高度表征单个用户，并提供对用户身份的相当准确的指示。
This paper describes a simple, software based keyboard monitoring system for the IBM PC for the continuous analysis of the typing characteristics of the user for the purpose of continuous authentication. By exploiting the electrical characteristics of the PC keyboard interface together with modifications to the internal system timer, very accurate measurements can be made of keystroke interval and duration, including measurements of rollover. Rollover patterns, particularly when typing common diphthongs, can be highly characteristic of individual users and provide quite an accurate indication of the users identity.
