Security And Traceability of Information In IoMT Network Through Blockchain

Abstract

Traceability and Authenticity is one of the important parameter which needs to be addressed in any type of system. In medical field, it is really very important to ensure traceability of information as a minor error can create a significant problem for both patients and doctors. Most of the times, the nodes in IoMT networks sense some data and report it to the next level whenever there is any event. Any inaccurate/wrong information may mislead a nurse/doctor. In traditional system there is no reliable and efficient mechanism for traceability and security of information Therefore, it is difficult to ensure that whether the information that was provided by the sensors was incorrect, tempered or compromised on its way to desired destination. Sensor nodes sends data to cloud on any platform where the information is being stored according to its time as the time of a particular reading is really important. This information can be accessed by the Doctor who is sitting at a distant place. It is responsibility of the Doctor to analyze the data received and prescribe medicine or send the required feedback or instructions to the local doctors/nurses or IoT devices like infusion pumps etc. in fully autonomous environment. In this research work we will propose a blockchain based authenticate and confirmation framework which will ensure the security and traceability of a transaction that is tampered.
