Hi Zheng,

it is really hard to do that. I guess you'll need to have platform support
for such a feature. Maybe you could ask Christopher Tarnovsky
about such technologies (chris.tarnovsky at ioactive.com). He is a
kind guy and an expert when it comes to security chips/technologies
on the hardware level :) .

Best Regards
