| description | Abstract Growing applications of Internet of Medical Things (IoMT) devices have revolutionized the healthcare sector because of remote patient tracking, diagnosis, and data-supported decision-making. The kind of medical data collected from these devices, however, is very sensitive, which makes it very vulnerable to issues of security, privacy, and integrity. This paper suggests a way to keep IoMT data safe using the Algorand blockchain, XChaCha20-Poly1305 encryption, and different types of decentralized storage. Using the platform’s fast, highly scalable, and highly secure architecture, Algorand blockchain framework makes sure that encrypted patient medical records are stored permanently and cannot be changed. To properly encrypt sensitive IoMT data before storing the data in DSNs including IPFS, Storj, and Filecoin, a modern stream cipher called ‘XChaCha20-Poly1305’ is used. Decentralized storage ensures data accessibility and distribution simultaneously, minimizing reliance on associated server points that are susceptible to single points of failure. Besides data secrecy, accuracy, and anti-intrusion attack breakout measures, this work explores the security measures implied by this architecture. Additionally, it assesses the efficacy of various decentralized storage options and highlights their benefits and drawbacks when it comes to storing large amounts of medical data. It can be concluded that the proposed framework is cost-effective and capable of expansion and implementation in the modern healthcare environment of IoMT data protection. |
