Android HealthCare Applications using Blockchain

A mobile application is deployed to collect health data using various sensors from personal wearable devices, manual input, medical devices, and synchronize data to the cloud for data sharing with healthcare providers and health insurance companies. To preserve the integrity of health data, within each record, a proof of integrity and validation is permanently retrievable from cloud database and is anchored to the blockchain network. Moreover, for scalable and performance considerations, the proposed system adopt a tree-based data processing and batching method to handle large data sets of personal health data collected and uploaded by the mobile platform. By developing a web application to find out nearest location of healthcare providers and health insurance companies. In the proposed system, KNN (K-Nearest Neighbours) and Haversine algorithm is used to provide information about health data and for further processing. This project represent a Blockchain-based approach to sharing user data to healthcare providers and health insurance companies.
