摘要
提出了一种以加密型二维码作为"软钥匙"的手机门禁系统。该系统中,携带身份信息的软钥匙以二维码形式由手机端软件生成,且具有时效和次数限制。使用时,手机客户端软件首先生成软钥匙并显示在手机屏幕上,门禁端软件驱动摄像头获取手机屏幕上的软钥匙图像并通过集成于门禁端的身份验证模块对软钥匙进行解密验证,通过身份验证后驱动电控制开关打开门锁。本系统实现了钥匙、用户和门禁的分布式管理,解决了现有刷卡门禁系统成本较高、维护不便等问题,为各类"智能门禁"和"远程门禁"应用需求提供了可行办法。
This paper presents a system of mobile access control based on an encrypted QRCode, called soft-key , which had limit of using times and life time. When used, firstly, a key was got by client soft installed on mobile and was displayed on screen of mobile, secondly, the image of the key was obtained from a camera integrated in access end, thirdly, identification information was captured from the image and was checked by authorization module, finally, if checked successful, the door was opened by an electric control switch. This method solves the problem of high cost, inconvenient maintenance of old access control system based card, and provides a feasible way for all kinds of intelligent access control and remote access control applications.
