Facial Recognition

摘要

AS the name suggests,facial recognition is where a computer or hardware device determines the unique characteristics of a person's face,based on still images or video,to identify them.In today's world of widespread terrorism,identity theft,criminal activity and online socialising,its use is becoming widespread.In many cases,people's photos are available on the internet-whether they want it or not.Some people may not even be aware of it.These photos can be fed into facial recognition software and used to identify and even track individuals,whether by government organisations or third parties.Apart from law enforcement and social media applications,modern smartphones such as the iPhone X,Galaxy Note 9 and LG G7 can use facial recognition to automatically unlock the device for its owner and prevent use by others.Commercial organisations such as casinos also use facial recognition to enforce bans against specific individuals and for other reasons,which will be discussed later.Facial recognition comes under the heading of biomet-ric systems,just like fingerprint or iris recognition.
