An online ad company called Turn is using tracking cookies that come back to life by using a hidden undeletable number that Verizon uses to monitor customers’ habits on their serviced devices. The company called Turn utilizes this number to respawn tracking cookies even after they are deleted by Verizon users.
Max Ochoa, Turn’s chief privacy officer admitted “We are trying to use the most persistent identifier that we can in order to do what we do.”
This controversy has been noted before as a new form of tracking by the telecom industry and has been deployed to shadow mobile phone and tablet users. Both Verizon and AT&T users noticed their carriers were inserting these tracking numbers into all their Web traffic that transmits from their users’ phones. Irregardless if they attempt to opt out or not.
After Verizon’s and AT&T’s users complained that the tracking number could be used by any website they visited from their phone to track their behavior serendipitously (what sites they went to, what apps they used.)
Only AT&T discontinued the practice in November. However Verizon continued to do so, assuring users that “it is unlikely that sites and ad entities will attempt to build customer profiles” when using their numbers as identifiers.
