Privacy vs. Security vs. Anonymity

posted by Sasha Romanosky

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
• Anonymous: being unidentifiable in one’s actions
