My blogger friend over at GetUSB.info has a great article on the difference between USB Copy Protection vs. USB Encryption technology. A lot of people might get confused by USB flash drive companies who try to market copy protection as encryption. Well, don’t get this wrong as it could be very costly for your classified information.
Greg also mentions TrueCrypt, a free open-source encryption software you can use to secure your USB flash drive.
In short; USB copy protection secures a file or set of files so they cannot be copied – thus copy protection. USB encryption scrambles the source files so they cannot be read unless you decrypt them. Take a moment and think about this…there is a BIG difference.
