Emerging degrees of privacy

Given that ‘privacy’ is a property that emerges from good Security, more particularly from Confidentiality (and Integrity), there’s two avenues to succeed in this field:

1. If quick and maybe even too dirty: Data minimalisation (as e.g., here, in Dutch)
2. Else (OR?): Fine-grained protection, also against the default Read all down the stack (user / end point / comms channels / applications / middleware / servers / storage — with the latter maybe crawling up and down the stack again when virtualizing in the cloud)
3. Because binary’s not my thing and keeping it real (i.e. (!) not being consistent) is: Would any of you have pointers to some science on possible degrees or levels of privacy ..?
   The idea keeps floating around in my skull. Including degrees of invasion! Where sometimes, the required degree (as set by the subject) would be less than the degree for some government agency so everything goes … for this some data point only. Yes, Value creeps in as a boring subject but isn’t everything. Should be a field of study …?

Thanks anyway for all your pointers on the last item… (none); hence:
