networks, Bluetooth Low Energy (BLE), Wi-Fi, and various network protocols may be utilized in different scenarios.


transmission and storage is crucial to prevent unauthorized access and misuse. Blockchain technology holds promise in addressing these concerns by providing a robust solution [11]. Blockchain enables the creation of a secure and tamperproof ledger for medical records, accessible only to authorized parties. Each transaction or modification to the record is securely recorded on the blockchain, allowing for easy tracking of record access and changes. Another promising technique is the use of NFTs, which possess characteristics such as immutability, traceability, and uniqueness [12]. NFTs can help ensure secure access to medical records while maintaining patient privacy. Ownership of the NFT can be easily transferred to other authorized parties as required, maintaining the integrity and privacy of the records.
