Some very constructive comments after my previous posting on the naivety of privacy - thanks to all who participated. So to address this problem that we are often talking cross purposes and without any common frame of reference we need to first take a look at in what terms we're framing privacy [of information systems].
Typically we see that privacy is addressed or framed in seven broad areas:
Each of these areas most certainly overlap but we have the difficulty of switching between these frames. For example, it is often the case that if we have great system security, then privacy is of little concern because we've addressed the problem of data leakage; however we haven't addressed the problem of data content because this is largely irrelevant to security. Similarly if we have great access control we don't have to worry about the data getting into the wrong hands? Or possibly that if we've presented the user with the necessary consents then all is fine?
If we firstly deconstruct each area and examine how each views privacy, then attempt a cross-referencing exercise between these, then we might actually have a basis for constructing, at least a framework for a common terminology and semantics.
