A youth uses a trash bin in central London, Monday, Aug. 12, 2013. Officials say that an advertising firm
must immediately stop using its network of high-tech trash cans, like this one, to track people walking
through London's financial district. The City of London Corporation says it has demanded Renew pull the
plug on the program, which measures the Wi-Fi signals emitted by smartphones to follow commuters
as they pass the garbage cans. (AP Photo/Lefteris Pitarakis) (The Associated Press)
