信息越来越多地采用数字格式，我们现在所做的几乎所有事情都依赖于数字身份进行身份验证和授权。无论身份验证系统多么强大，在身份验证阶段之后，都无法持续验证用户是否仍然是成功登录的同一个人，从而使系统不受保护。本文通过使用基于击键动力学的生物识别技术，提出了一种可用的突破性方法，用于自由输入文本的连续认证。我们的主要目的是通过调整和改进击键动力学算法的参数来减少所需的样本量，同时提高（或至少不降低）精度性能。
Information is increasingly in a digital-only format and almost everything we do nowadays depends on a digital identity for authentication and authorization. No matter how strong the authentication system is, after the authentication phase, there is no continuous verification that user is still the same human being that successfully logged in, thus leaving the system unprotected. This paper presents a usable breakthrough approach for continuous authentication with free typed text through the use of biometric techniques based on keystroke dynamics. Our main purpose is to achieve a reduction of the required sample size, while improving (or at least not worsen) precision performance, by adapting and improving parameters on a keystroke dynamics algorithm.
