The Federal Trade Commission should stop “creepy” electronic billboards from surreptitiously harvesting cellphone data, New York’s senior senator said over the weekend.

“Your personal cellphone should not become a James Bond-like gadget that is used against you by some company,” Democratic Sen. Chuck Schumer said in remarks delivered in Times Square. “It’s your phone, your privacy. You should have to give them permission to follow you when you drive by or walk by their billboard.”
