Real-Life Application of IoMT in Healthcare

IoMT has truly revolutionized healthcare by connecting medical devices, which helps in the smooth exchange of data as well as its collection. This helps healthcare providers make data-driven decisions. Let us tell you about a recent study in Scientific Reports, which mentions the system called EHRGuard that combines IoMT and blockchain technology. This system in the research study tackled key challenges such as data privacy, trust, and interoperability.

In this setup, the patient wore medical devices, such as sensors, that monitored heart rate, glucose levels, and oxygen saturation. These IoMT devices sent real-time health data to a small, local gateway device, such as a Raspberry Pi, instead of storing this data on a blockchain, which is time-consuming and costly, thus utilizing a more efficient approach. So, the data was first saved in a secure off-chain database, and then only a cryptographic fingerprint (hash) of the data was saved on the blockchain.  This helped ensure the data is tamper-proof while protecting the privacy of personal details. 

All in all, this study is the perfect example of IoMT and how its integration with blockchain can increase transparency. Furthermore, EHRGuard required consent before any data was modified or accessed also ensuring that only authorized users can view or handle health data.
