Of course, there is no substitution for encryption to ensure that your information remains secure. However, you can add additional layers of protection by making your data difficult to find or recognize. To this end, ThinkGeek has a great product that they call the Hacked And Frayed Spy Flash Drive. The device is described as a “2GB flash drive cleverly disguised as a frayed and broken USB cable.”
Bruce Schneier notes:
This is a 2 Gig USB drive disguised as a piece of frayed cable. You’ll still want to encrypt it, of course, but it is likely to be missed if your bags are searched at customs, the police raid your house, or you lose it.
The comments on Schneier’s post raise a question I had, namely whether it would be better to have a complete cable rather than a frayed cable.
