ABSTRACT
Recent years have witnessed a paradigm shift in the storage of Electronic Health Records (EHRs) on mobile cloud environments, where mobile devices are integrated with cloud computing to facilitate medical data exchanges among patients and healthcare providers. This advanced model enables healthcare services with low operational cost, high flexibility, and EHRs availability. However, this new paradigm also raises concerns about data privacy and network security for e-health systems. How to reliably share EHRs among mobile users while guaranteeing high-security levels in the mobile cloud is a challenging issue. In this paper, we propose a novel EHRs sharing framework that combines blockchain and the decentralized interplanetary file system (IPFS) on a mobile cloud platform. Particularly, we design a trustworthy access control mechanism using smart contracts to achieve secure EHRs sharing among different patients and medical providers. We present a prototype implementation using Ethereum blockchain in a real data sharing scenario on a mobile app with Amazon cloud computing. The empirical results show that our proposal provides an effective solution for reliable data exchanges on mobile clouds while preserving sensitive health information against potential threats. The system evaluation and security analysis also demonstrate the performance improvements in lightweight access control design, minimum network latency with high security and data privacy levels, compared to the existing data sharing models.
EXISITNG :
Medical data intervention is always possible because the existing system is a centralized distributed system. In the existing system there are drawbacks such as no data privacy, less reliability and lack of network security in sharing the health record among the cloud servers. Also failure in single point can happen in existing system which results in unavailability of data. It also lacks in data retrieval process since the existing system faces storage issues
PROPOSED SYSTEM:
In the proposed blockchain technology based EHR provides decentralized system. This proposed system provides trustworthy access control mechanism by using the smart contracts in order to achieve secured EHR sharing between the patients and the health care providers including hospital and pharmacist. In the proposed system, a patient can register and feed his details regarding health which then will be converted into hash value using SHA 256 algorithm and then it will be embed to a QR code. Using this hash value the doctor and the hospital can view the details permitted by the patients. The doctors can now provide the medicines by viewing the patients record and this will be converted into a block. This block can be viewed by pharmacist and automatically invoice will also be created. This proposed system also integrates crypto currency that is Ethereum which preserves sensitive health information against threats. The crypto currency can also be used to book a doctor’s appointment and also pay for it.
