In order to improve the intelligence of the medical system, this paper designs and implements a secure medical big data ecosystem on top of the Hadoop big data platform. It is designed against the background of the increasingly serious trend of the current security medical big data ecosystem. In order to improve the efficiency of traditional medical rehabilitation activities and enable patients to maximize their understanding of their treatment status, this paper designs a personalized health information system that allows patient users to understand their treatment and rehabilitation status anytime and anywhere, and all medical health data distributed in different independent medical institutions to ensure that these data are stored independently. As a distributed accounting technology for multi-party maintenance and backup information security, blockchain is a good breakthrough point for innovation in medical data sharing. In this paper, the system realizes the personal health data centre on the Hadoop big data platform, and the original distributed data are stored and analyzed centrally through the data synchronization module and the independent data acquisition system. Utilizing the advantages of the Hadoop big data platform, the personalized health information system for stroke has designed to provide personalized health management services for patients and facilitate the management of patients by medical staff.

为了提高医疗系统的智能性，本文在Hadoop大数据平台之上设计并实现了一个安全的医疗大数据生态系统。它是在当前安全医疗大数据生态系统趋势日益严重的背景下设计的。为了提高传统医疗康复活动的效率并使患者对他们的治疗状态有最大的了解，本文设计了个性化的健康信息系统，使患者用户可以随时随地了解他们的治疗和康复状态以及所有医疗健康数据分布在不同的独立医疗机构中，以确保这些数据被独立存储。作为用于多方维护和备份信息安全的分布式记帐技术，区块链是医疗数据共享创新的良好突破点。该系统在Hadoop大数据平台上实现了个人健康数据中心，并通过数据同步模块和独立的数据采集系统对原始分布的数据进行集中存储和分析。利用Hadoop大数据平台的优势，针对中风的个性化健康信息系统旨在为患者提供个性化的健康管理服务，并方便医务人员对患者进行管理。通过数据同步模块和独立的数据采集系统集中存储和分析原始分布的数据。利用Hadoop大数据平台的优势，针对中风的个性化健康信息系统旨在为患者提供个性化的健康管理服务，并方便医务人员对患者进行管理。通过数据同步模块和独立的数据采集系统集中存储和分析原始分布的数据。利用Hadoop大数据平台的优势，针对中风的个性化健康信息系统旨在为患者提供个性化的健康管理服务，并方便医务人员对患者的管理。
