When I first began my PhD, I was keen to properly sort and define any new terms and reconcile them with my own education and experience. Three terms that always seemed to be intermingled were: Privacy, Security and Anonymity. Certainly they are related, but I wanted to be a little more specific and understand exactly when and how they overlapped.
First, let’s establish some basic definitions. For the purpose of this blog post, the following definitions will suffice (I’ll address alternative definitions later):
• Privacy: having control over one’s personal information or actions
• Security: freedom from risk or danger
• Anonymity: being unidentifiable in one’s actions
Next, create a Venn diagram with three overlapping circles (each circle representing one term). Then, within each area, try to provide examples that reflecte those properties. That is, imagine some situation where you would have security without privacy, or security without anonymity. When can you have all three? When can you be anonymous but lack privacy?
This may not be as easy as it seems. Certainly it helps once the definitions are set, but if nothing else, I think it’s a useful way to separate and identify the essence of these words (at least, as each of us sees them) and the contexts in which they may or may not exist. Before you continue, take a minute, examine the diagram above, and try to think of examples to fit each area.
