This sure puts a new spin on AT&T's old slogan "reach out and touch someone":
AT&T Labs has been working on a bioacoustic system that could allow your cell phone or other device to securely transfer data through your body – in particular, through your bones. The system has the additional benefit of being completely secure – that is, if someone else has got your phone, they won’t be able to get to that data.
“Our ultimate goal is to get data transferred securely through the bones of people allowed access to it,” Brian Amento, the head of the project told me. “We’ve gained enough interest that its worth pursuing.”
