Blockchain – addresses the legitimate previous concerns of security, scalability and privacy of electronic medical records

Mittwoch, September 28th, 2016

1.Patient – the patient is provided a code (private key or hash) and an address that provides the codes to unlock their patient data.  While the patient data is not stored in the blockchain, the blockchain provides the authentication or required hashes (multi-signatures, also referred to as multi-sigs) to be used to enable access to the data (identification and authentication)
2. Provider – contributors to patient’s medical records (e.g. providers) are provided a separate universal signature (codes or hashes or multi-sigs). These hashes when combined with the patient’s hash establishes the required authentication to unlock the patient’s data
3. Profile – then the patient defines in their profile, the access rules required to unlock their medical record
4. Access – if the patient defines 2-of-2 codes, then two separate computer machines (the hashes) would have to be compromised to gain unauthorized access to the data – in this case, establishing unauthorized privileged access becomes very difficult when the machines types differ, operating systems differ and are hosted with different Providers
