Does facial recognition technology really work?
The officials at London’s Metropolitan Police certain hope so. They are using sophisticated software to track down those suspected of being involved in the recent riots in the UK. An anonymous source says, “The issue is that you have to have a good picture of a suspect and it is only useful if you have something to match it against. In other words, the suspect already has to have a previous criminal record.”
In the United States, however, this is not necessarily the case. Someone has been spotted that looks like Casey Anthony and great efforts are being made to compare photos. (For details, see “Casey Anthony Photos in Facial Recognition Software” at
The short answer to “Does facial recognition technology really work?” is “not always,” but it’s getting better. Does the target in a picture wear a baseball cap and sunglasses? If so, that may block the software, but much depends of the clarity of the picture.
In an extreme case, wear one of those face masks you see in Japan.
