Recent Trends in IoT Healthcare-based Blockchain Solutions

This review revolves around the idea of inculcating and amalgamating all the possible forte of healthcare that can be governed and handled by Blockchain Technology (BCT). Relating back to all the archaic systems involved in the healthcare sector, the entire process was quite slow and many a time leads to a significant amount of delay in any process, be it report of the patient, tracking data from the smart watch, ruling out appointment from a doctor, medicine prescription and many more. BCT in fusion with the Internet of Things (IoT), leads to generating a completely revolutionary and robust system that expands its range from very minute detail to a completely new horizon. As predicted by 2022, more than 18 billion devices will be available across the world; thus, managing this data that is related to healthcare, devising BCT for same can yield some exponential results in advancement in health care sector. This entire healthcare data is quite vulnerable to all the cyber-attacks and all the collected valuable information may be at a huge risk; hence by deploying BCT, security can be greatly increased. BCT is nothing but an immutable time stamp series of records, just like an array working; when even one of the blocks is initialized with any value of information, that piece of information will remain there forever. This review attempts to group together all such various fields that can be brought under a single umbrella covering the range of fields that can be governed by BCT in accordance with IoT for the development of health care sector.
