New car seat concept uses your butt print as identification

If Fido can distinguish people and other pooches by their backsides, why not a seat? When students at the Advanced Institute of Industrial Technology in Tokyo, Japan asked that question, they came up with a car seat fitted with 360 sensors that makes a map of the pressure applied by your posterior. Among the six rumps tested, the seat was 98 percent accurate at sorting one from another.

The ultimate aim is to work with automakers to develop an anti-theft solution that would be available in the next few years. With such a small testing pool, it's too early to start asking the difficult questions about real-world viability (especially when you start to factor in things like different articles of clothing, Costanza wallets, and so on), but we have a feeling this kind of technology will find an application somewhere.
