[sudo-discuss] anti-surveillance mask: not so easy...

Thu May 15 21:26:48 PDT 2014

The arts of triangulation should be assumed to be advanced enough that,
depending on resources and faculty, no physical concealment should be
considered adequate enough to not anticipate (and even assume) recognition.
Efforts, such as masks, add to triangulation algorithms.

As with communication-privacy, identity-privacy ultimately comes down to
life-style awareness. Life. Style. Awareness.

That's my perspective, anyway.
