基于区块链应用模式的铁路旅客身份认证系统

Railway Passenger Identity Authentication System Based on Blockchain Application Model

采用"区块链技术+不对称加密+生物识别+身份认证"应用模式,依托智能手机客户端设计与开发一套铁路旅客身份认证系统.基于Ethereum开发平台,应用truffle开发框架,实现铁路旅客身份认证系统智能合约的编写与部署.系统针对传统铁路身份认证模式的不足,将旅客身份数据分布式存储,弱化中心化服务器的压力,提升旅客身份数据的安全性和鲁棒性;进行生物信息认证确保旅客对身份信息的所有权;利用非对称加密技术在保护旅客隐私、实现实名制的前提下增强数据的透明性.基于区块链应用模式的铁路旅客身份认证系统能够让用户身份实现本地存储、信息摘要链上校验,实现铁路旅客身份信息数据访问的细粒度控制,保障铁路旅客身份信息安全,提升铁路旅客的乘车体验.

A railway passenger identity authentication system is designed and developed by using the application mode of"blockchain technology + asymmetric encryption + biometric identification + identity authentication" and relying on smart phone client. By the Ethereum development platform and truffle development framework, the intelligent contract of railway passenger identity authentication system is compiled and deployed. Aiming at the shortcomings of traditional railway identity authentication system, using distributed storage of passenger identity data to ease the pressure of centralized server, the system improves the security and robustness of passenger identity data. The system ensures the ownership of passenger’s identity information by bioinformatics authentication, and uses asymmetric encryption technology to enhance the transparency of data under the premise of protecting passenger’s privacy and realizing realname system. The railway passenger identity authentication system based on blockchain application model can enable user identity to be stored locally and checked information abstract on the chain, realize fine-grained control of access to railway passenger identity information, guarantee the information security of railway passenger identity, and enhance the passenger experience.
