Re: Blockchain Technology use in biohazard access restriction?
What if the blockchain gets infected by the eBola virus... 
*joke.
I would not trust anything as important as that to a public decentralized system. I think the technology they are refering to is Multi sig access control...
"Moreover, recent innovations in Bitcoin such as Multi-sig, which requires a general consensus over multiple key holders to sign a transaction or a contract, can also help to remove the single-point failure. In the multi-sig model, any action requires m number of digital signatures out of n based on the users agreement. Otherwise the action cannot be performed on the blockchain. This way, access control is decentralized, removing a single potential point of failure, and can also be tracked in the blockchain. Moreover, this model would reduce leakage of data, information and access in any secure facilities and laboratories."
Multi sig can be incorporated into current access control systems.
