一种事件驱动的生物特征识别框架服务的设计与实现

Design and implementation of an event-driven biometric identification framework service

提出并实现了一个生物特征识别框架服务。通过定义规范的应用和驱动接口标准,提供统一的加密存储,提高了生物特征数据的安全性并实现多应用共享生物特征;通过抽象并扩展出高兼容性的设备驱动模型和驱动行为,实现多种生物特征识别的支持;通过灵活的消息反馈机制,实现多种人机交互方式的用户引导。

A biometric identification framework service is proposed and implemented.By defining standard application and driver interface standard,it provides unified encrypted storage,improves the security of biometric characteristic data and realizes multiapplication shared biometric.By abstracting and extending the devicedriven model and drive behavior with high compatibility,multibiometric identification is supported.Through flexible message feedback mechanism,user guidance of various humancomputer interaction modes is realized.
