当谈到一般的身份验证，特别是生物测定时，我们设想这样一种情况，即用户提供身份并提供该身份的证明，以获得对某些服务的访问。这种身份验证(称为静态身份验证)在首次访问服务时完成，并将在整个会话期间有效，直到用户从该会话登录为止。大多数身份验证方法非常适合这种(静态)身份验证，例如用于访问计算机或网站的众所周知的用户名/密码组合。在本文中，我们将讨论一种不同类型的身份验证，它将在会话开始后应用，并将监视当前用户是否与执行初始静态身份验证的用户相同。这种新型身份验证称为动态身份验证或连续身份验证。我们将特别关注计算机上的会话，在那里我们监控用户的键入行为以检测异常。生物识别中使用的常规技术不再适用。我们将解释两者之间的区别
When talking about authentication in general and biometrics in particular, we envisage a situation where a user provides an identity and gives proof of this identity, in order to get access to certain services. This kind of authentication (called static authentication) is done when rst accessing a service and will be valid throughout a full session, until the user logs o from that session. Most authentication methods are very well suited for this kind of (static) authentication, e.g. the well known username/password combination for access to computers or websites. In this article we will discuss a dierent kind of authentication, which will be applied after the start of a session, and will monitor if the current user is the same as the user who performed the initial static authentication. This new type of authentication is called dynamic authentication or continuous authentication. We will in particular look at sessions at a computer where we monitor the typing behavior of the user to detect anomalies. Normal techniques used in biometrics cannot be applied anymore. We will explain the dierences between
