I'm not sure if this is really a better solution.
The Problems I see are:
- when the device is used it's the same as with temp/swap files on a
- when it's not used someone could find a usb-stick lying around ...
Using Linux I think it's very easy to implement.
And if you delete the data on the usb-device before logoff, you could
also do this to your temporary files or the swap-area. And with an
usb-device you have the complication that you can't be sure that the
data was erased. Perhaps you pulled it out a little to fast ...
I'd prefer to put such important temporary data on an encrypted
filesystem. But the solution I'm using right now has the disadvantage
that after I mounted that filesystem everyone with root-privileges can
read it. My workaround is to only use it on a system were no one but me
has access. But the why encrypt that stuff if I'm the only user?
If someone on this list has a solution for my dilemma I'd be very
