| 摘 要： | 结合用户击键特征与单点登录系统中身份认证方案,提出了一种基于击键特征匹配的单点登录系统。该系统提取用户登录时的击键特征作为用户的生物特征,并将其作为登录用户身份信息合法性和有效性验证的重要判定依据。根据击键统计数据的正态分布特性和区间估计原理,计算出设定置信度下用户的平均按键持续时间、击键速度的特征值区间。最后利用统计学模型对用户击键特征进行匹配。

| Abstract: | Combining the characteristics of keystroke and user authentication schemes, a single signn system based on matching keystroke characteristics is proposed. In the system, the keystroke features are extracted as the biometric when user logins, which is used as an important criterion for legitimacy and effectiveness of the identity information. According to the characteristic of normal distribution and the theory of interval estimation, the interval of characteristic value for average keystroke time and keystroke speed is calculated with the given confidence level. Finally, the user＇ s keystroke characteristics are matched in accordance with the statistical model. |
