Though a superhero, Bruce Schneier disdanes the use of a mask or secret identity as ‘security through obscurity’.
Found that on the web somewhere. It’s so funny. To give a little context, Bruce Schneier is crypto and computer security guy. Security through obscurity is the school of thought that systems which are closed/black boxes are secure because people don’t know enough about it to hack. This is generally considered a very weak argument by the security community.
