Privacy is a concept that has been debated and argued throughout the last few millennia by all manner of people. Its most striking feature is that nobody seems able to agree upon a precise definition of what it actually is. In order to discuss privacy in any meaningful way a tightly defined context needs to be elucidated. The specific context of privacy used within this document is that of "personal data", information about an individual stored and/or transmitted electronically in Internet protocols. This context is highly relevant since a lot of work within the IETF involves defining protocols that can potentially transport (either explicitly or implicitly) personal data. This document aims to establish a basic lexicon around privacy so that IETF contributors who wish to discuss privacy considerations within their work can do so using terminology consistent across the area.
