RSA Security and i-Mature are working on a technology for verifying users’ age by analyzing finger bones.

One places a middle finger against a device which uses ultrasound waves to check over a dozen biometric attributes, including how much calcium is present (kids have less than adults).

The system would be useful at keeping younger children from adult sites that employ the technology and operators of chat rooms meant for kids could use the technology to keep out adult predators.

The device won’t hit the market for at least one or two years.
