基于移动设备手写签名认证系统的设计与实现

由于移动设备具有通过外部的无线网络访问数据、体积小容易丢失等特征，给操作带来方便的同时．也给后台数据库带来很大的安全隐患。文章针对基于移动设备的无线网络应用系统，在Windows2000和Windows Mobile2003操作平台上．利用Microsoft的Visual Studio．Net2003和．NET Compact Framework开发环境，设计和实现了基于移动设备手写签名认证系统。实验结果表明：在少量样本数据情况下，对于非专业模仿签名的错误接受率FAR为3．65％．而错误拒绝率FRR为2．9％。该系统增强移动设备访问数据的安全性，提高操作员认证的效率．具有很强的舅用性。

Design and Implementation of a Handwriting Signature Verification System Based on Mobile Devices

Because the mobile device has the features of accessing data by the wireless networks beyond the internal local network, small volume and losing easily, it brings convenience of operations and hidden trouble of security simultaneously. Aiming at the wireless networks application system based mobile devices, we have designed and implemented a handwriting signature verification system based on mobile at Windows 2000 and Windows Mobile 2003 platforms with development tools of Visual Studio .Net 2003 and .Net Compact Framework. The experiment results show the FAR decreases to 3.65 and the FRR decreases to 2.9% for no-special imitating signatures with a little sample data. This system can enhance the security of data accessed by mobile devices, increase the efficiency of operator's verification,and have good practicability.
