【摘要】 门禁,又称出入管理控制系统,是一种管理人员进出的数字化管理系统。常见的门禁系统有:密码门禁系统,IC卡门禁系统,非接触IC卡(RFIC卡)门禁系统,生物识别门禁系统等。其中生物识别门禁又包括指纹、虹膜、掌纹、语音等系统。传统的密码输入不安全,卡容易遗失和被盗,以及指纹被复制的可能,都决定了单识别门禁系统不可能具有太高的安全性。本文对该系统的技术领域及其在国内外的发展状况进行了详细的调查和分析的基础上,提出了一种结合RFIC、指纹识别及传统密码输入的复合系统方案,该方案充分结合了射频识别技术、指纹识别技术以及密码输入的优点,彻底杜绝了有可能发生的安全隐患,提高了系统的安全性能。本论文主要采用了射频识别技术与指纹识别技术,以嵌入式ARM器件作为中央处理器,使系统具有较高的响应速度,可以直接运用存储卡中的所要辨别的信息而独立工作,完成RFIC卡的有效性识别、指纹的认证及密码的验证,也可通过上位机实现识别及验证工作。本系统具有响应速度快,稳定性好,安全性能高等特点,可以满足人们日益增长的安全需求,具有非常高的市场前景。更多还原

【Abstract】 Entrance guard system, as well called access controller system, is the digital management apparatus to control the access of the personnel. The familiar sorts of the entrance guard system are password entrance guard system, IC card system, non-contact IC card system, biometric identification system, etc. And the biometric identification entrance guard system includes fingerprint system, iris system, palm print system and voice system and so on.Traditional password input is an insecure way. The card is easily dropped or stolen, as well as the fingerprint has the possibility of being copied, which make sure that single identification entrance guard system has no possibility possessing high security. Basing on detailed investigation and analysis of the technology domain development status inside and outside of the country, this paper bring forward a system scheme combined the technology of RFIC, fingerprint, password input. This scheme used the merits of radio frequency technology, fingerprint identification technology and password input method. It absolutely put an end to the hidden trouble possibly occurred, and improved the secure capability of the system.This system primarily made use of radio frequency recognition technology and fingerprint identification technology. It used embedded ARM apparatus as the center processor, which provided the system with a high response speed. According to the exploitation requirement, this system could choose the way not corresponding with monitor computer and working alone with the requisite information stored in the memory, or the way using monitor computer to achieve the identification of RFIC card, fingerprint or password. It has the characteristics of high response speed, good stability, speICal security, etc. It can satisfy the people’s day-increasingly safety requirement and some speICal situation. So, it has a high market prospect.更多还原
