As one of living characteristic identifies ,it has been applied in many kinds of safe system:Simple Lockfast System;Complicated Controlled Gate System;Fingerprint and Intelligence Card combination application;Network Safety depending on the fingerprint identifies etc.

作为生物特征识别的一种，由于它具有其它特征识别所不可比拟的优点，使得自动指纹识别被广泛地应用于各种安全系统中：简单保险柜/箱系统；较复杂的门禁系统；指纹与智能卡结合应用；基于指纹识别系统的网络安全等。

It is well known that fingerprints of an individual are unique and are normally unchanged during the whole life.depends on this kind of unique and stability,we can get up a person together with his fingerprint, and can verify his identity by comparing his fingerprint with the fingerprint keeped in advance.this is the fingerprint-identify technique.as one of living characteristic identifies ,it has been applied in many kinds of safe system:simple lockfast system;complicated controlled gate system;fingerprint and intelligence card combination application;network safety depending on the fingerprint identifies etc.

摘要众所周知：每个人的指纹是唯一的并且终生不变的。依靠这种唯一性和稳定性，我们就可以把一个人同他的指纹对应起来，通过比较他的指纹和预先保存的指纹进行比较，就可以验证他的真实身份。这就是指纹识别技术。作为生物特征识别的一种，由于它具有其它特征识别所不可比拟的优点，使得自动指纹识别被广泛地应用于各种安全系统中：简单保险柜/箱系统；较复杂的门禁系统；指纹与智能卡结合应用；基于指纹识别系统的网络安全等。
