According to a news item published in the BBC, citizen surveillance is on the rise. USA and Britain are the countries using state of the art gadgets to keep common people under their watch. The goal is to create a system that will match the facial image of the person with their gait, height, weight and other elements to identify a person instantly. With newer technology, radio waves can be used to find out if anyone is on the other side of the wall and may be their heart and breathing rates as well.
"As you walk through a crowd, we'll be able to track you. These are all things that don't need the cooperation of the individual." said Professor Challapa from Maryland University. 
Changed times
Since 9/11 terror attacks are on the rise throughout the globe and countries like US and UK are always on the hit list. Round the clock surveillance gives rise to privacy issues even though it might lead to reduced crime rates. The terror suspects come from various strata of the society often mingling with the unsuspecting crowd making peer to peer surveillance nearly impossible. This system will provide means of non-contact surveillance.
However the public doesn't seem to mind! Opinion polls, both in the US and Britain, say that about 75% of us want more, not less, surveillance.
