We hardly need to be reminded that we are living in an age of confusion... a lot of us have traded in our beliefs for bitterness and cynicism or for a heavy package of despair, or even a quivering portion of hysteria. 
Opinions can be picked up cheap in the market place while such commodities as courage and fortitude and faith are in alarmingly short supply.
  -- Edward R Murrow, "This I Beleive", 1951.

Confused is a deniable authentication layer, also termed a duress proxy, currently working with Linux/PAM.
It allows a predetermined action to be taken when a specific password/phrase - different from the user's normal password - is entered at any login prompt.

A Windows version is being worked on and hopefully OS X too.
