摘要随着高科技的飞速发展,智能安全管理已进入人们的社会生活,智能安全管理是以安全防范技术为先导,以防人为主,以安全防范为手段,建立了具有检测、延时、应对三大基本要素的预防性安全防范服务支持系统。防止损失和防止犯罪是一种公共安全服务。46221
本文提出了一种基于加密二维码作为“软钥匙”移动电话解锁门禁控制系统。在该系统中,通过二维码的形式,将手机中的身份信息生成“软钥匙”,并具有时间和次数限制。在使用时,手机客户端软件首先生成这种二维码软钥匙,门禁终端软件驱动摄像头获取手机屏幕上的软按键图像,通过集成的接入终端认证模块的软密钥解密识别和认证通过驱动电控制开关打开门。
该系统实现了分布式管理的关键,用户和访问控制,解决了现有的卡访问控制系统成本高,难以维护,对各种“智能访问控制门禁”和“远程访问门禁”的应用提供了一种可行的途径。

ABSTRACT
With the rapid development of high-tech, intelligent security management has entered people's social life, intelligent security management based on security technology for the pilot to prevent people mainly to security as a means of detecting the establishment of a delay, respond three Great basic elements of preventive security service support system. Loss Prevention and crime prevention is a public safety services.
This paper presents a two-dimensional code based encryption as a "soft key" mobile phone unlocking access control system. In this system, in the form of two-dimensional code, the phone identity information generating "soft key", and have the time and frequency limits. In use, the mobile client software first generates such a two-dimensional code soft keys, access control terminal software driven camera to obtain images of soft keys on the phone screen by soft key to decrypt the identification and authentication of integrated access terminal authentication module through the drive electrical control switch to open the door.
The system implements the key, user management and access control distributed to solve the existing high-cost card access control system, it is difficult to maintain, for a variety of "Smart Access Control Access" and "Access Remote Access" application provides a practicable way.
Key words: mobile phone access control; soft keys; two-dimensional code; intelligent control; security.
