People’s health data should not be monopolized by a few but
must be safely controlled and utilized in transparent manner
for the public interest.
Patients’ health data has been in the hands of the third
parties who try to monopolize and commercialize it. Thus, it
was nearly impossible for patients to know to what extent
their health record is collected, who needs it and how it is
used. However, on blockchain that provides transparent
environment in data usage, anyone can look up the transactions
of data and ultimately patients can retain control and
authority over their own health data.
