Abstract
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.
