Description

一种门禁系统及其控制方法 One kind of access system and control method

技术领域 FIELD

[0001] 本发明涉及本发明涉及安防技术领域,具体涉及一种门禁系统及其及控制方法。 [0001] The present invention relates to the field of the present invention relates to security technology, and particularly relates to an access control system and control method. 背景技术 Background technique

[0002] 现有的门禁系统的安全信息识别模式大体分为生物特征识别方式和输入验证方式,其中,常见的生物特征识别方式如通过采集人的声音、虹膜、面部或指纹等信息进行身份验证,常见的输入验证方式如密码验证、ID卡验证、手机卡验证等等。 [0002] Security information identifying the mode of the existing access control system can be divided into input mode and the biometric authentication mode, wherein the common biometrics authentication means such as by collecting the human voice, iris, face or fingerprint information, etc. common input validation methods such as password authentication, ID card verification, phone card verification, and more.

[0003] 输入式验证方式的优点是实施简单,从安全性角度,除非合法用户自行泄露,否贝U,非法用户必须通过破解的方式来通过验证,如果安全系统无安全漏洞,一般破解难度较高,但常见的密码式验证方式最大的问题在于容易被人在密码输入场所窃取密码,例如常见的通过安装摄像头窃取银行卡密码的方式,或者利用与用户有关的个人信息试出密码,例如用户的电话号码、生日等等。 Advantage [0003] input type authentication method is simple to implement, from a security point of view, unless the legitimate user-leak, no shellfish U, illegal users must break the way through verification, if the security system has no security vulnerabilities, usually crack difficult than high, but the biggest problem common password-based authentication mode is easy to be input places to steal passwords in the password, such as a common by installing cameras to steal bank card passwords manner, or use of personal information about the user try out passwords, such as user telephone number, date of birth and so on.

[0004] 随着生物特征信息技术的发展,近年来指纹识别技术应用越来越普遍,相对于常见的输入式验证方式,其优点是用户无需记录密码,手指即密码,且两个不同人拥有相同指纹的几率极低,因此,安全性也较高,但近年来有报道,带有指纹图像的胶质手指,还有牙科石膏手指模型,都能够成功躲过指纹识别器的识别,有些犯罪团伙甚至从死者身上割下来手指后进行犯罪活动。 [0004] With the development of information technology, biometric, fingerprint recognition technology in recent years more and more common, with respect to the common mode input validation formula, its advantage is that users do not need to record passwords, ie password fingers, and have two different people the probability of the same fingerprint is very low, therefore, safety is also high, but has been reported in recent years, gum fingers, as well as dental plaster model with finger fingerprint image, are able to successfully escape recognition fingerprint reader, some crime even after the gang cut off the fingers from the dead body to carry out criminal activities. 当然,活体指纹识别技术也已应用成熟,可杜绝上述假手指问题,但非活体指纹识别仪目前依然还在广泛应用中,其安全风险依然存在。 Of course, the live fingerprint identification technology has applications mature, fake finger can eliminate the above-mentioned problems, but not live fingerprint identification device currently still in widespread use, the safety risks remain.

[0005] 可以,以上两种安全信息识别模式都有着固有的缺点,任一种都不是最好的识别模式。 [0005] can be, two or more pattern recognition security information have inherent disadvantages, any one of the identification pattern is not the best.
