Computer controlled surveillance

It is commonly known that surveillance is usually done on some sort of electronic device, with a human monitoring the video feed, pictures, voice recording, etc. New technology has taken this job away from humans and left it in the hands of computer programs. The way it works is that computers will have programmed into the ways suspicious people act, and it will direct video cameras to follow the person if the computer feels they are suspicious. For example, the computer can recognize if the same person has travelled by one location in an airport more than 4 times. It will then follow them and can decide whether that person is a threat based on details that most humans cannot even see. These details are called “micro-expressions.” They are short involuntary expressions that every human makes as they are thinking and moving about. The US military has begun a program called Project Hostile Intent that uses these computer controlled cameras to track down suspicious people and monitor their micro-expressions to determine their motives. This new technology is much more accurate, because often terrorists are trained not to use expressions, but micro-expressions are impossible to suppress. One other benefit is that racial profiling will be minimized, as long as the computer programs rely mostly on micro-expressions for ruling out threats.
