較為全面的對身份認證系統做了分析比較，并著重研究分析了生物特征識別身份認
證和動態口令身份認證，在此基礎上提出了一種身份認證技術綜合的分類方法。從認證雙方享有的知識因子的角度出發，明確了共享因子的概念；從動態身份認證中的動態驅動因子不同，把其劃分為時間驅動型和事件驅動型。

From the point of view of the factors that both sides possess, the paper puts forward the concept of share-factor; in the light of the different drive-factor in dynamic identity authentication system, divides the authentication system into time-drive type and affair-drive type.
