Verizon to allow opt-out from mobile ‘supercookies’
Verizon will soon allow customers to opt out of having an identifier placed on their phones that had alarmed privacy advocates due to its ability to let third parties persistently track customers.
The identifier or customer code drew concerns primarily because it created so-called “supercookies” that could not be deleted by users. Verizon customers have had the ability to opt out of the company’s advertising programs, but not out of having that identifier placed on their devices.
Now, “we have begun working to expand the opt-out to include the identifier referred to as the UIDH [unique identifier header], and expect that to be available soon,” a Verizon spokeswoman said Friday via email. She added that “Verizon never shares customer information with third parties as part of our advertising program.”
