An IoT Cloud Security System Powered by Blockchain for Secure Preservation of Electronic Health Records

Common public under-monitored medical care – patients have multiple medical reports from multiple hospitals around the globe. The timely availability of medical reports from multiple sources without any tampering is crucial for patients under critical care. Blockchain Technology has been implemented to tackle the problems of the medical field – doctors, nurses, and medical professionals. A Blockchain with the Internet of Things (BIoT) is being suggested here, combining both potentials to achieve a solution to the problem statement. Research studies scrutinize the vulnerability of IoT devices to various threats and attribute them to the Lax Protocol. The criticality and sensitivity, along with the existing vulnerability, reiterates the need for better solutions. Such predispositions pave the way for attackers to swiftly destroy CIA (Confidentiality, Integrity, Availability) triad elements, the core of security. The prime goal of this work is to ensure electronic health against Distributed Denial of Service (DDoS) and probe attacks exercising recommended mechanisms like Time to Live (TTL) and DoS Protection for Distributed Ledgers (DPDL). Their focus on the limitations of IoT in protecting electronic health record records from external hackers and attacks is crucial.
