摘要
设计了一个基于本地验证的金融卡保护系统,通过对持卡用户进行人脸摄像,以及相应图像变换处理,提取出人脸眼球、鼻翼、嘴角5个特征部位几何位置,计算出8个特征值,以此在金融卡应用终端对用户真实信息进行本地验证,确保银行卡使用安全。系统在VC++建立的模拟实验环境下,以200个模拟真实样本与20个模拟假冒样本进行测试,获得了良好的实验效果。
A bankcard protecting system is designed, which is based on local authenticating. First, the image of user＇s face is taken and handled, then the eyes and nose wing and mouth corners are located, and finally 8 characteristic values on face＇s Geometric properties are gained. The values are used to confirm the user to protect the bankcard being misappropriated. The system has been tested in the virtual subject built with VC＋＋ on 200 virtual real samples and 20 virtual fake samples and shown a good result.
