The 4GB flash drive encrypts all data with 128-bit AES, and then adds an extra layer of security: a self destruct feature. If anyone tries to use a brute-force attack to guess your password, the drive will automatically erase itself after 25 wrong guesses. Of course, if you have a really easy password, and a data thief can figure it out in under 25 guesses, you're out of luck. For the rest of us, this could be a good solution for keeping on-the-go info out of the wrong hands.
