Microsoft-owned adtech Xandr accused of EU privateness breaches


An adtech enterprise owned by Microsoft is the goal of a criticism backed by European privateness advocacy group, noyb — a nonprofit that punches far above its weight in the case of chalking up strikes in opposition to knowledge protection-infringing tech giants.

For its newest motion, noyb is supporting an unnamed particular person in Italy to lodge a criticism in opposition to Xandr with the nation’s knowledge safety authority. The criticism has been filed beneath the European Union’s General Data Protection Regulation (GDPR) — that means, if it prevails, it might result in fines of as much as 4% of Xandr’s mother or father entity’s Microsoft’s world annual turnover.

Xandr stands accused of transparency failings and breaches of the info entry rights to individuals within the bloc whose info is processed to create profiles which can be used for microtargeted promoting bought by way of programmatic advert auctions. The criticism additionally contends the adtech firm is utilizing inaccurate details about individuals.

Specifically, noyb alleges Xandr is breaching Articles 5(1)(c) and (d); 12(2); 15 and 17 of the GDPR.

The criticism asks the info safety authority to analyze and, if breaches are confirmed, to order Xandr to come back into compliance. noyb can be suggesting it ought to impose a nice of as much as 4% of annual income on Xandr’s mother or father (NB: Microsoft’s full yr income for 2023 was near $212BN).

Acquiring regulatory threat?

Microsoft picked up on the “data-enabled know-how platform”, because it referred to as Xandr, on the again finish of 2021, to increase its digital promoting enterprise, although Xandr retained its structural autonomy and operates as a separate entity. Microsoft’s press launch on the time talked of the acquisition enhancing its “retail media options”, in addition to touting “strengthened monetization for publishers by way of bigger first-party knowledge entry and a full funnel advertising and marketing providing”. It didn’t point out the prospect of amped up regulatory threat flowing from the acquisition.

The drawback, in keeping with the noyb-backed criticism, is that Xandr is failing to answer any knowledge entry requests from people wanting their private info deleted or corrected. The criticism hyperlinks to a “hidden” webpage the place it says Xandr publishes knowledge entry metrics. Per this web page, between January 1, 2022 and December 31, 2022, the corporate obtained 1,294 entry requests and 600 deletion requests — however denied each single one.

A explanatory word on the webpage states: “Access and deletion requests are denied once we are unable to confirm the identification and jurisdiction of the requestor. Due to the pseudonymous nature of the info Xandr collects on its Platform, we’re unable to confirm the identification of the shoppers who made entry and deletion requests when such requests aren’t tied to another identifiers, and due to this fact we denied such requests.”

So Xandr seems to be claiming it doesn’t need to adjust to GDPR knowledge entry rights as a result of the data it holds on people is pseudonymous.

However the criticism argues it’s not credible for a corporation whose whole enterprise hinges on profiling people for focused promoting revenue to say it can’t establish the individuals whose info it holds.

Commenting in an announcement, Massimiliano Gelmi, knowledge safety lawyer at noyb, mentioned: “Xandr’s enterprise is clearly primarily based on protecting knowledge on tens of millions of Europeans and focusing on them. Still, the corporate admits that it has a 0% response fee to entry and erasure requests. It is astonishing that Xandr even publicly illustrates the way it breaches the GDPR.”

It’s price noting that the GDPR takes an expansive view on what constitutes private knowledge and knowledge that has undergone pseudonymization stays private knowledge — that means these holding such information should abide by pan-EU authorized necessities corresponding to offering knowledge entry rights.

Guidelines on knowledge topic entry rights adopted by the European Data Protection Board (EDPB) final yr embody an illustrative instance from the realm of microtargeted promoting by which the Board factors out an adtech firm ought to be capable of “exactly establish” a person who’s requesting entry to their private knowledge from the identical terminal tools as is linked to their promoting profile (i.e. by way of cookies dropped on it) since “a hyperlink between the info processed and the info topic could be discovered”.

If a person requests their knowledge in one other manner, say by e mail, the EDPB steerage suggests the adtech firm ought to request more information from them with a view to establish the related promoting profile and fulfil their knowledge entry request. Specifically the steerage says a person would want to offer the cookie identifier saved of their terminal tools.

It’s not clear what steps Xandr took to establish the advert profiles of the individuals requesting entry to or deletion of their knowledge.

Returning to the criticism, noyb’s analysis additionally unearthed what seems to be excessive ranges of inaccuracy inside the information Xandr holds on people — which can increase separate questions for its clients concerning the high quality of its advert focusing on providers. But it additionally has authorized significance given the GDPR furnishes people with the best to rectification of incorrect knowledge held about them.

EU individuals can depend on the GDPR for different rights, too, together with the power to ask for a replica of their knowledge. Again, noyb alleges that is one other space the place Xandr isn’t compliant. It wasn’t in a position to get a replica of the complainant’s knowledge from Xandr itself however fairly used a topic entry request to one in every of its knowledge dealer suppliers.

“Thanks to an entry request with the info dealer — and Xandr provider — emetriq, we all know that no less than a part of Xandr’s database consists of wildly inaccurate and contradictory private knowledge about individuals,” it writes in a press launch. “According to emetriq, the complainant is each female and male, has an estimated age between 16-19, 20-29, 30-39, 40-49, 50-59 and 60+. The complainant additionally has an revenue between €500-€1,500, €1,500-€2,500 and €2,500-€4,000. Furthermore, the identical particular person is searching for a job, is employed, a scholar, a pupil and works in an organization. That firm, in flip, employs 1-10, 1,000+ and 1,100-5,000 individuals on the similar time. “

“It is difficult to think about how these knowledge classes can be utilized for correct advert focusing on,” noyb provides. “Although emetriq isn’t the one knowledge dealer supplying knowledge to Xandr, it needs to be assumed that this info is used for advert focusing on.”

Commenting additional, Gelmi additionally wrote: “It appears that components of the promoting business don’t actually care about offering advertisers with correct info. Instead, the info set comprises a chaotic number of conflicting info. This can probably profit firms like Xandr as they will promote the identical consumer as younger and outdated to totally different enterprise companions.”

Microsoft has been contacted for a response to the criticism.

A spokesperson for noyb advised us it doesn’t count on the criticism to be referred from Italy to Irish knowledge safety authorities, beneath the GDPR’s one-stop-shop course of, as a result of Xandr is established within the US. This company construction suggests the adtech agency could possibly be focused with additional complaints in different EU Member States the place it has processed locals’ knowledge — additional dialling up regulatory threat.

The noyb-backed criticism highlights earlier analysis it mentioned has proven Xandr collects extremely delicate details about people for advert profiling functions, corresponding to knowledge about their intercourse life or sexual orientation, faith beliefs and political beliefs. The GDPR units a very excessive bar — of specific consent — for legally processing delicate classes of information.

It’s not clear how such consents would have been obtained from people whose knowledge Xandr holds. But guests to web sites could also be one supply of data as monitoring for adverts could be triggered by individuals accessing publishers’ content material. In the EU such websites ought to ask guests for his or her permission to monitoring nonetheless business customary mechanisms for acquiring individuals’s consent are themselves accused of breaching the GDPR.
