Menlo Park, CA : Facebook is all set to monitor your behaviour online. It is developing a software that would allow them to start collecting data on details like how long users hover their cursors over elements on the page and whether their newsfeed is visible as they browse the site.
Thus it is going to monitor your behavior by the movement of your mouse's cursor or mouse's clicks.
Facebook is the first company to try something like this. Stock photo site Shutterstock, for one, tracks users' every move, from the photos they click on to the photos they think about clicking on.
