While the technology is in its infancy, the Department of Homeland Security wants to identify you not only by your fingerprint, but by your body odor. They hope to develop the technology as a lie detector. That's right- when you lie, you stink.
Bloodhounds know each human scent is unique. But can a machine really tell if you're omitting an odor when you lie? What if a hapless victim of TSA was simply unable to shower because they were being held for questioning upon discovery of their lotion bottle? I think that even the innocent will sweat if interrogated.
