Anti-riot by face recognition software

British police plan to use facial recognition software to detect dangerous elements in the Olympic Games next year, but the riots last week forced them to use software earlier than expected.

Many free web sites - such as Facebook social networking sites or Picasa photo sharing sites - have long used face recognition software . British security officials intend to use the software to screen dangerous subjects at the 2012 London Olympic Games.

AP quoted Andy Trotter, head of the UK traffic police, as saying that face recognition software had been used by riot policemen in England to identify those who caused the most serious riots. in this country for several decades.

Facial recognition software divides people into multiple cells. It measures the distance between the nose, eyes, lips, ears and other facial features. Since the software has been upgraded, the software used by the British police is more effective than the old version. An expert said the software could identify suspects based on photographs taken with surveillance cameras and cell phones. It can also recognize photos on a passport or website.

An official of the London Metropolitan Police has revealed that police previously used facial recognition software to track down criminals. In most cases, publishing photos of suspects in mass media remains the most effective and least expensive way of finding suspects.

According to another police officer, to use the software you have to have a clear picture of the suspect as a basis for comparison with the new image.

"In other words, suspects are breaking the law and their information is stored on file ," the official said.
