  In this paper, we propose a robust health record storage and management
system built on blockchain technology to address the challenges faced by
traditional healthcare record systems. The primary advantage of employing
blockchain in healthcare record management is its ability to provide a secure
and decentralized platform. Unlike traditional centralized databases, where a
single point of failure can compromise data integrity and security, blockchain
distributes data across a network of nodes, ensuring redundancy and resilience
against cyber-attacks. This distributed nature of blockchain enhances data
security and privacy, crucial considerations when dealing with sensitive health
information. Central to our proposed system is the utilization of smart
contracts, which are self-executing contracts with predefined rules and
conditions. Smart contracts automate processes related to health record
management, such as data access, sharing, and updating, based on predefined
permissions and protocols. This automation not only streamlines administrative
tasks but also reduces the risk of human errors and ensures data accuracy and
consistency. Furthermore, our system prioritizes patient empowerment by
granting individuals complete control over their health records. Patients can
securely access and manage their data using cryptographic keys, granting
permission to healthcare providers or other authorized entities as needed.
Overall, our proposed health record storage and management system on the
blockchain offer significant advantages over traditional systems, including
enhanced security, data integrity, transparency, and patient control. By
leveraging blockchain technology and smart contracts, healthcare organizations
can revolutionize their record management practices, and maintaining secure
ecosystems.
