It is very difficult for a prisoner inside of the jail to keep it secret from a prison guard these days. While the prison population usually enforces a very strict code of honor that includes never squealing to law enforcement, Securus Technologies has innovated away to get information out of prisoners without their knowledge.
Securus Technologies is a telephone company. If you have ever watched a television show or movie that goes inside of a prison, you might remember seeing a line of telephones installed into a wall. Prisoners lining up to use the telephone for short periods of time in order to call their friends and family on the outside. Well, Securus Technologies is the company that provides those telephone services.
All of those telephone calls being spoken into those telephones on the walls of prisons are recorded by Securus Technologies. All of these telephone calls are saved in a massive computer somewhere. This information is then made available to law enforcement and law enforcement can search the entire database virtually instantly. Securus Technologies has made searching the database almost as easy as searching for websites on the Internet. In fact, they may have made it even easier.
The software that searches this database locks on to a certain person’s voice. It analyzes that voice on a variety of different proprietary levels. Each voice is completely unique like a fingerprint. Once the software has a hold of the unique features of a particular voice, it can then search the entire database for any instances where that voice is heard.
This allows prison guards to hear every single word uttered by a particular prisoner through those telephones. Now prison guards do not need prisoners to tell on each other explicitly because they are doing so implicitly through this innovative technology.
