A new biometric face scanner from the Japanese company Sagawa Advance has taken the technology to the next level, able to differentiate between identical twins with no problems at all. It does this by using an infrared scanner to analyze a whopping 40,000 data points on your face.

This is a good thing, because Sagawa Advance's scanner is used as access to high-security areas such as power plants and medical factories where they've got to make sure that it's really the plant supervisor entering and not his evil twin bent on the destruction of the human race. That's always the worst. [Digital World Tokyo]

Being able to identify the differnces between identical twins is cool, but not that useful. First of all, identical twins aren't a very large part of the overall population. Secondly, it's pretty rare that you are trying to identify if a person is John or his twin Bill with a computer.

The much bigger problem that needs to be solved with these types of systems is to allow them to successfully identify that a person is the same person as one they already have a pic of. Different angles, lighting, haircuts, glasses, and age all make it very difficult for these type of systems to accurately identify that the person is the same person.
