We've learned to be highly suspicious that the GPS, camera and microphone in our smartphones can be used to track our every move, listen into our conversations and watch our most intimate moments. But what about the act of tapping and swiping our screens? Can that be used by a bad actor? Researchers from CSIRO's Data 61 have found just that.

It's said necessity is the mother of invention. About 15 years ago, Dr Gernot Heiser, from Data 61, looked ahead and, despite being fit and healthy, could foresee a day when he might need an implanted, life-supporting device such as a pacemaker. And he didn't like the idea the it might be attacked remotely. So, he set out to build a trustworthy computing platform that could not be hacked.
A new piece of research from Data 61, the digital research arm of CSIRO, has found the energy patterns we generate when we walk can be used to power mobile devices and to authenticate our identity. It turns out we have, in Star Trek parlance, unique energy signatures.
