Data Storage Methods

The Problem with Current Medical Data Storage Methods

The Problem with Current Medical Data Storage Methods

Medical data is currently stored and managed solely
on the individual servers of hospitals where the data is generated.
Submitting medical data to other hospitals or insurance companies takes a lot of time
and money because servers are not connected across hospitals,
and hospitals cannot arbitrarily use patient data without each individual’s consent.

Problem ❶

Difficulty submitting medical data

Records from Hospital A are issued as paper certificates or stored on a CD and submitted to Hospital B or an insurance company, etc.

Problem ❷

Difficulty utilizing medical data

A lot of pharmaceutical, medical consulting, and other companies wish to utilize this highly-valuable medical data, but hospitals have difficulty sharing this data because they cannot obtain consent from every single patient.

What is Blockchain Cloud?

Rather than using a specific server or specific cloud,
Blockchain Cloud splits and saves a single piece of data using
at least seven services and 21 data centers for its massive quantity of medical data.
When all the data is combined, only the individual owner of the data
with the blockchain key can access the data, keeping information as important as
medical data securely stored and safely utilized.
