Not very far from now (looking into the future, Scotty and Captain
Kirk), health information will be a worldwide web.
Mayor players are diving into this trillion dollar business.
Health information will need to be accessible, and blockchain can be
used to guard all interaction between systems.
You can find dozens of documents which handle about this.
Blockchain is a service that supplies functionality such as:
non-repudiation, trust between parties in the public domain.
These functionalities can be achieved using existing technology.
Blockchain is existing technology. The first work on a cryptographically
secured chain of blocks was described in 1991 by Stuart Haber and W.
Scott Stornetta. In 1992, Bayer, Haber and Stornetta incorporated Merkle
trees to the blockchain as an efficiency improvement to be able to
collect several documents into one block. So 25 years old, which is
quite old in IT history
NICTIZ sees some application of Blockchains at the IT-Infrastructure
level: authentication, authorisation, and Access control.
OpenEHR is not a specification at the IT-Infrastructure level.
There a re a lot more applications of blockchain in healthcare ICT, also
described in the document I linked to, in very simple examples.
Most important are transparent and provable tracking order of events,
independent from sending/receiving computers, tracking of messages, it
will be impossible to send a secret message, for example.
It is very convenient for the all stakeholders to be able to be sure
messages are only send to what they approved too at a moment they
approved too, containing what they approved too.
This will become very important in the future when exchanging medical
data will explode in volume.
