Noun
a person who publicly supports or recommends a particular cause or policy
Advocates of biometrics systems say this makes the system more scientific. Computers can compare exact measurements of facial features in order to make matches.
It analyzes bodily characteristics (the features of the face) to establish a person's identity. A biometric system undertakes not just to display or record an event but to instantly identify the people involved in it.
Verb
guess or be aware of (what will happen) and take action in order to be prepared
The organizers of any huge sporting event have to anticipate trouble and try to stop it before it starts. Security officials at Tampa's Raymond james Stadium hoped to do so by using machines that recognize faces.
Verb
record or express accurately in words or pictures
Every fan was of interest to security officials, who used tiny, hard-to-see cameras to capture a shot of each person who passed through the stadium gates.
At first, cameras mounted on the district's utility poles monitored streets for fights, drug deals, and other crimes. The police might see a crime as it was happening or use the video to help in any consequent investigations.
Noun
a part or aspect of something abstract, especially one that is essential or characteristic
At a very basic level, it simply makes many people angry to see elements of a "Big Brother" society, where authorities spy on people wherever they go, in the United States.
Adjective
supplied with the necessary items for a particular purpose
Banks, shopping malls, and government buildings are already equipped with security cameras, and no one has a problem with that. Why complain about the system used at Raymond James Stadium?
Verb
make partial or minor changes, typically to improve something or make it less extreme
Then Tampa modified those cameras to link directly to the police department's own database. This made them true biometric tools. Instead of humans analyzing a video to see who was depicted, machines did the identifying.
Noun
the application of scientific knowledge for practical purposes, especially in industry
People captured on camera were not told their pictures were being taken. None gave permission. The technology has not been proven to be reliable. What if the system points out an innocent person as a criminal by mistake?
