World's 1st Voicecode Security USB Drive - Voicelok
 

You wouldn't think there would be much to say about a USB flash drive, but in this case, what you say, and how you say it, is your key to data security. Advanced technical skills are definitely not required, because this is a plug-and-play device, requiring no software installation. All critical software is embedded in the flash drive itself, and it is fully functional the moment it is removed from the box.

After inserting the USB into a computer, red and green LEDs flash to signal to the user that the drive is ready to hear the password through its on-board microphone. Armed with a dedicated on-board microprocessor, the drive's voice-recognition software then sorts out the various nuances and frequencies of an authorized voice, and the only necessary password is a spoken one.
