voice protection.
How would you like to be able to positively identify any caller simply by their voice. Everyone has a unique voice pattern in the same manner that everyone has a unique finger print or DNA. Loss of personnel papers or credit cards would cease to be a problem if voice biometrics were employed to give positive identification to anyone presenting paper documentation. With voice authentication software protecting things like bank account numbers or tracking medical records their theft would no longer be a major issue. It would now take more than presenting the numbers to gain access. You would now have to present the correct voice.
