But this convenience comes at a cost. And the cost here is the increased risk of you loosing your important data and privacy, in case you miss, lose or get your USB Flash drive stolen by somebody. That is why every USB user must consider data encryption in USB Flash drives seriously. It is not that difficult.
TrueCrypt is a program for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data is automatically encrypted or decrypted right before it is loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc).
TrueCrypt not only protects your data in your hard disk, but it also has a useful feature for your USB Security by running in so-called “portable mode”, which means that it does not have to be installed on the operating system under which it is run.
There are two ways to run TrueCrypt in portable mode:
- After you extract files from the TrueCrypt self-extracting package, you can directly run TrueCrypt.exe. To extract files from the TrueCrypt self-extracting package, run it, and then select Extract (instead of Install) on the second page of the TrueCrypt Setup wizard.
- You can use the Traveler Disk Setup facility to prepare a special traveler disk and launch TrueCrypt from there.
Following is a simple tutorial on how to use TrueCrypt open source security for the USB Flash Drives.
