(there is an earlier paper from him available). He started with the right to be let alone, then moved on to data privacy (although I don't know what non-data privacy is). Next was the concept of privacy via randomized responses, where randomness is added to protect individual privacy.
ps: The subsequent presentations raised some interesting questions on timely topics. However, what is needed is to take the next step to practical implementation. As well as raising interesting areas for further research, this would also provide benifit to the community.
