A blockchain privacy-conserving framework for secure medical data transmission in IoMT

This technical paper introduces a privacy-preserving framework tailored for the Internet of Medical Things (IoMT), where low-power medical devices transmit sensitive data to a blockchain ledger. Given the resource constraints of IoMT devices, the authors propose a lightweight cryptographic approach that ensures data integrity and privacy without sacrificing performance. The framework incorporates advanced encryption techniques and a consensus mechanism optimized for low-latency network environments. The authors provide a detailed performance evaluation, comparing their proposed model against conventional transmission protocols. The study demonstrates that integrating blockchain into IoMT can achieve high security benchmarks while maintaining the operational requirements of remote patient monitoring systems. This research is particularly significant for the evolution of telehealth, as it provides a practical template for securing communication paths between wearable sensors and clinical decision-support systems, addressing both the privacy of the patient and the integrity of the collected clinical data.
