V3 sha256 based set intersection implementation, MVP
Simple interface (which will be improved by UX folks separately) which allows performing intersection between two sets where one set is Sender (think of carrier) and the other set is Receiver (curious healthy person), Receiver gets SHA256 of the elements of the set and tries to match with his own set using our App's interface. More details will be put soon
From what I understand that this would allow access to 2nd degree neighbours (contacts of contacts). With an external whiteboard (server) it would be possible do n-th degree contacts (i.e. the whole population) without compromising privacy; i did a small write up with the details here (point 2, point1 of the paper is already addressed from what I see).
