Applications of Ensuring Security and Privacy Using Block Chain with IoT for Health Record

The healthcare system has key security and privacy requirements when considered like an enterprise, such as safeguarding patients' medical records from unwanted access, protected drug tracking, secure connection with transportation such as ambulances, and secure and smart e-health surveillance. With suitable security measures, block chain has brought novel concepts in security and safety of medical data, and it may reconcile the discrepancy among sharing data and confidentiality. We combine the strengths of both block chain and cloud computing in this research to provide a confidentiality method for block chain and IoT. This strategy incorporates IoT and delivers IoT services to block chain nodes; in the meantime, it gathers, examines, operates, and preserves in the identity validation for health information. Interaction and addresses the inadequate computing capabilities of some block chain nodes in order to confirm data validity and feasibility. The proposed approach is efficient, as demonstrated by the simulation experiment. It can preserve and verify the integrity of medical data while also addressing issues such as high computer complexity, data exchange, and privacy protection.
