Intelligence medical research
Use the intelligence agencies as a trusted partner to conduct health research based on private health histories and genetic data.
There is a conundrum in medical research -- the genetic and detailed data is inevitably personally identifying, and so, it's hard to share and compute with (homomorphic encryption may solve this, but I don't know of exactly how at this point).
However, the society could benefit immensely from personal medical histories and genetic data.
So, being a rather neutral party, not interested in profiting from the health insurances or otherwise from customers, the intelligence agencies could actually be useful as a party that legally is permitted to conduct the research with such private and personal data.
Btw., examples of companies illegally obtaining such data exist, e.g., [link].
