You're going out with friends mid-week, and you don't want the boss/significant other/parole officer to find out. But it's a birthday celebration, and Facebook's auto-tagging the pictures your buddies upload like a dirty snitch. The first piece of advice: never "friend" your parole officer. The second? Maybe grab a pair of these "privacy" glasses from software security firm AVG. You, of course, can see my visage above, but AVG claims the technology in the specs means facial recognition software (like that of Facebook) will not.
