We propose using the human body for “storing” data used in devices for the imminent ubiquitous computing era. In the future, people will use information appliances as powerful creativity tools, using them for taking pictures, recording ideas, and recording voices. Removable medium are now widely used with such devices to record the data. However, data stored on a physical medium is troublesome to handle and thus hinders smooth knowledge creation. Natural storage using the human body would eliminate the physical burden.
