Ad Company Using Verizon Tracking Header To Recreate Deleted Cookies

itwbennett writes The story began a few months ago when it was reported that both Verizon and AT&T were injecting unique identifiers in the Web requests of their mobile customers. AT&T has since stopped using the system, but Verizon continues. Now, Stanford computer scientist Jonathan Mayer has found that one advertising company called Turn, which tracks users across the Web when they visit major sites including Facebook, Twitter, Yahoo, BlueKai, AppNexus, Walmart and WebMD, uses the Verizon UIDH to respawn its own tracking cookies.
