Yesterday, we discussed how voice biometrics can be deployed to monitor inmate phone calls from prison. Another related application, is the use of voice biometrics to ensure that persons on house arrest, parole or probation are where they should be, when they say they are. The current approach is to use ankle bracelets to monitor these individuals. However, there is always the potential for these bracelets to be removed and placed on another person or object – rendering them worthless.
The voice biometrics process works as follows. A person who needs to be monitored at home is required to have a land line phone, and provide a base voiceprint. When the person is required to be at home, an automated system calls them, at scheduled or random intervals, and requests a sample voiceprint. If the sample voiceprint matches the base voiceprint, the system is able to verify that the correct individual is where, and when, they should be.
To those of us with teenagers, I can think of some additional applications!
