Terminology for Identity Management

One of the seemingly endless debates in identity management is exactly what everything is called. Today an update to “Anonymity, Unlinkability, Unobservability, Pseudonymity, and Identity Management – A Consolidated Proposal for Terminology” reminded me that people who think about anonymity have been trying to thrash this out for a long time. This document has been evolving for more than 5 years, and I rather like it. Here’s an example:

An identity is any subset of attributes of an individual which identifies this individual within any set of individuals. So usually there is no such thing as “the identity”, but several of them.

Not only does it have well thought out definitions, it also translates them into several languages, currently Czech, French, German, Greek and Italian. What, no Spanish?
