Can we use Quorum (or any other Ethererum variation) to save private data that can be shared with other parties for a temp period?
The use case is that: A patient can share his medical data that is related only to a specific category (radiology, dental, etc..). This is can last for a configurable time (ex. the doctor can see the data for the next 10 days only). And the doctor can see the history for a chosen period (ex. 1 year back only).
(Note: The question is about saving and sharing the full data, not only the hash of the record.)
