摘要:

为减小身份伪冒给企业和组织带来的内部威胁,提出了一种全场景下动态实时身份认证方法。利用伪造的鼠标异常构建动态身份认证场景;当出现连续的动态认证异常时,系统引导用户进行了由记忆游戏构建的固定场景身份认证。对15位用户进行了身份认证实验,得到了3.0%的拒真率、1.8%的容错率以及8.12 s的认证时间。实验表明,动态场景和固定场景身份认证的有效配合,不仅克服了固定场景无法实时身份认证的弊端,而且保证了用户的体验,同时提高了身份认证的准确率。

Abstract:

To solve the problem organization’s insider threats which was brought by internal staff through identity spoofing. A method of dynamic real-time authentication was presented. By faking exceptions of mouse to build dynamic authentication, when continuously consecutive authentication were abnormal, user was forced into fixed scene certification which was building of memory game. An identity verification experiment, in which 15 participants were involved, showed that the performance of proposed method was encouraging with FAR of 1.8% and FRR of 3.0% and authentication time of 8.12 s for authentication. The experiment shows that the method is not only real-time but also has a better user experience and accuracy.

Key words: insider threat, identity authentication, identity monitoring, SVM, mouse dynamics
