Is there any research done on attempting to use crypto for some smart scheme of anonymizing patient data bundles to: - allow for cryptographically safe usage of the bundles for research (with some limitations?) - make exact mapping of the health data bundle to a particular person impractical? Considering the miracles of public-key cryptography and blockchains, it would seem to me that there could be a scheme that would allow for something like this.
