Like a scene out of Total Recall, the BCI (brain-computer interface) has been developed to the point where they can be found in novelty or spywear stores. Scientists have taken an off-shelf version and shown it has the capability of hacking the brain and pulling details straight from your mind.
University of Oxford, California Berkeley and Geneva gathered computer science students. They were briefed as being part of a security experiment but nothing else. A series of banks, maps, PIN # and such were displayed and by following P300 brain signals, the scientists were able to deduce where they lived and their banks by reducing the random data by up to 40%.
This coupled with information-prying technologies like smartphones, energy smart meters and naturally, Facebook , reveals an increasingly disturbing capability to monitor almost everyone and the relative simplicity of more sophisticated attacks with even pedestrian technology. Food for thought.
