The area of personal data throws up a myriad of different
terms describing the protection of those data: anonymisation, de-identification,
data privacy, confidentiality, pseudonymisation, disclosure control, privacy
impact and so on. Unfortunately none of these terms is used consistent with
different authors, agencies and jurisdictions using the terms in different
ways.   

This lexical complexity gives rise to much confuse and
bemuse the practitioner as they attempt to navigate their way to best practice
in handling their data situation.

This talk has two purposes: firstly to provide some aids to navigation
which enable the practitioner to focus on what they must deliver and secondly
to provide an overview of the field in terms of where we are, what we now know
and what we are still finding out.
