Super-cookie crumbles: Verizon vows to kill off hated zombie stalkers

Verizon has corroborated down over a fingerprinting of subscribers regulating supposed imperishable “super cookies.”

In 2012, a US mobile telco started injecting singular identifying headers (UIDHs) into each HTTP ask users done to websites around a Verizon network. This authorised disreputable ad agencies to commend people as they changed from site to site, and arrangement ads presumably tailored to individuals’ interests.

Deleting all your cookies from your web browser, or regulating something like Chrome’s incognito mode, will not kill off a header – since it is extrinsic automatically by a carrier.

Customers could “opt out” of a system, though a X-UIDH formula would still be injected, permitting intelligent networks – like Turn in San Francisco – to follow people around a web regardless. The ad group stopped doing that about a week ago.

The per-subscriber headers caused a stink among remoteness warriors, due to a sweeping inlet of a injection and that it was unfit to mislay it. Campaigners during a EFF objected to a imperative inlet of a headers.

ATT was contrast a identical system, and forsaken that when it was exposed.

Now Verizon has pronounced that this time “opt-out” unequivocally means opt-out: it’s going to stop injecting UIDHs into subscribers’ web trade if they switch off a complement in their comment settings.

Previously, if we opted out, stats about where you’ve been online were funded from advertisers, though as we’ve seen with Turn, that didn’t stop dynamic networks.

“Verizon takes patron remoteness severely and it is a executive care as we rise new products and services. As a mobile promotion ecosystem evolves, and a promotion business grows, delivering solutions with best-in-class remoteness protections stays a focus,” a association told El Reg in a matter on Friday.

“We listen to a business and yield them a ability to opt out of a promotion programs. We have begun operative to enhance a opt-out to embody a identifier referred to as a UIDH, and design that to be accessible soon. As a reminder, Verizon never shares patron information with third parties as partial of a promotion programs.” ®
