Reliability and security are not proerpties that are limited to blockchain. The actual method of storing data on MediBloc does not include writing the data directly to the blockchain, but storing it in an external storage (for example IPFS, etc.) So only the hashed value of the data is written on the blockchain. This is the simplest way to prove reliability of our system while minimizing the size of the data written on the blockchain. With this method, it is easy to determine when the data is manipulated- can identify when anyone besides the owner tries to handle the data. We believe that this will ensure the reliability of healthcare data. In addition, we plan to provide a patient-based/ patient-centered encryption method and not a hospital-based encryption method.
In addition, from the viewpoint of security, the conventional hospital-based encryption method (in general, all the patient data are encrypted by using the same encryption method in a certain medical institution.) In such a case, In fact, analyzing the causes of outbreaks of medical data in recent years has been a mistake or intentional outflow of the hospital internally. I want to encrypt it. This gives you more security than the current system (data distribution and security by individual encryption).
