一种身份验证法的提议

Proposal of an Authentication Method

到目前为止,多种类型的身份验证方式已经被研究出来进行网上的身份确认。以密码和PIN码为基础的字符数字型身份验证方式自身有很大问题,仍然依赖人类有限的记忆。最近,有人提出一种诉诸视觉信息的验证方式——图形口令,即用照片来验证身份。这种方法在安全性上还有待于提高。在本文中,针对图形口令目前所存在的问题,我们推出社团身份验证系统,不采用照片而采用肖像为口令,并且该系统还可以为某个社团进行社团成员身份验证。本方法的有效性是通过一组主体实验来证明的。

Recently, various types of personal authentication methods have been studied to confirm a persons＇ identity in the on-line system. However, the alphanumeric characters and authentication methods based on passwords and PINs hold severe problems, and still must rely on the limitation of human＇s capacity of recollection. Recently, ＂graphical password＂ , using visual information for authentication methods that utilize photographic image for authentication, has been proposed. However this method holds some problem on security. In this paper, Community Portrait Authentication System that uses a portrait as the authentication image is proposed to solve the issues of the previous graphical passwords. Moreover, It has the idea of the ＂community authentication＂ that a member of a certain community consisting of a party of human can be authenticated. The validity of the proposed method is confirmed by a set of subject experiments.
