Last year you‘ll recall Verizon Wireless found itself in hot water after being caught modifying user packets to insert stealth tracking technology. By embedding each packet with a unique identifier traffic header, or X-UIDH. Verizon and its marketing partners were not only able to ignore user browser preferences and track their behavior around the Internet, they were then able to use this technology to build detailed user profiles. Verizon Wireless launched and operated the technology for two years before security researchers even noticed the program, and it required another six months of public pressure for Verizon to even offer an opt-out option.
