Interesting book just released called How to Disappear: Erase Your Digital Footprint, Leave False Trails, and Vanish without a Trace by Frank M Ahearn and Eileen C Horan.
Probably a little over the top – I have no desire to remove my digital footprint any time soon, but Ahearn and Horan illustrate just what information is being tracked and offer tips on how to reduce unwanted digital exposure.
The book goes much further than just your digital footprint and suggests setting up sticks in New Zealand! Lots of tips over at disappear.info
Remember, if you are about to perform a digital Houdini be sure to make a back up of your online content first 😉
