基于区块链的儿童生长发育数据追溯系统设计

Design of children's growth and development data traceability system based on blockchain

目的:针对儿童生长发育数据追溯困难的现状,设计一种基于区块链的儿童生长发育数据追溯系统。方法:该系统采用浏览器/服务器(Browser/Server,B/S)架构设计,采用超文本预处理器(hypertext preprocessor,PHP)、HTML5和JavaScript编程语言编程,通过区块链数据结构、数字签名、散列函数和对等网络等关键技术构建。整个系统主要包括用户管理、患者管理、体检管理、区块链管理和系统日志5个功能模块。结果:该系统可以记录和共享儿童生长发育数据,实现了儿童生长发育数据可追溯。结论:该系统具有操作简单、去中心化、安全性高、隐私性好等特点,可解决儿童生长发育数据难以追溯的问题,为儿童保健科医生的诊疗工作提供了帮助。

Objective To design a blockchain-based child growth and development data traceability system.Methods A blockchain-based child growth and development data traceability system was designed with B/S architecture,programmed with PHP,HTML5 and JavaScript languages and constructed with the technologies of blockchain data structure,digital signature,hash function and peer-to-peer network,which was composed of five functional modules for user management,patient management,medical examination management,blockchain management and system log.Results The system recorded and shared child growth and development data,realizing traceability of child growth and development data.Conclusion The system developed gains advantages in easy operation,decentralization,high security and privacy,solves the problems in child growth and development data traceability and provides assistance to pediatricians effectively.
