Fujitsu’s Tamatebako self-destruct erasing drive
Fujitsu is solving that problem with a secured USB Memory Device called "Tamatebako". It offers 2GB capacity and supports AES 256-bit encryption. This ‘self-destruct’ drive is not like the device used in Mission Impossible which will meltdown or blow up. It will just simply deletes all the data stored in the "Tamatebako" within a given time frame (set time: 10 minutes to 7 days).
There's also a password authentication: If you enter an incorrect password, the data recorded will be deleted automatically.
No more worries about your important files being leaked out..
