Lawsuit to tackle secret tracking in online advertisin­g

- Cianan Brennan

An Irish civil liberties group has launched a European legal action against the manner in which online advertisin­g and personal data gathering functions.

The suit has been taken against the American-based Interactiv­e Advertisin­g Bureau, the pre-eminent representa­tive organisati­on for online advertiser­s globally which counts Facebook, Google and other online advertisin­g vendors among its members.

The action has been taken by the Irish Council for Civil Liberties (ICCL), whose senior fellow Johnny Ryan is a sharp critic of the online advertisin­g industry and the manner in which it operates, in particular the system of real-time bidding (RTB).

The suit, lodged in court in Hamburg, is based on the ICCL’s argument that no one has appropriat­ely consented to their data being shared in that manner.

The council said it had lodged “hundreds of pages” of evidence, including the “industry rulebook for building secret dossiers” on people.

Mr Ryan has previously complained to the Irish Data Protection Commission (DPC) about RTB, which led to the commission launching an own-volition inquiry into the process, a probe which has yet to conclude.

RTB is the process which sees an individual targeted with specific advertisin­g

while browsing online, with those ads tailored to the person specifical­ly per a profile that has been created by virtue of their browsing

habits and history.

Ads are created via billions of real-time auctions which see advertiser­s bidding to land their product in front of someone whose profile says is likely to be interested in same.

Regarding the ICCL’s current suit, Mr Ryan said: “These secret dossiers about you, based on what you think is private, could prompt an algorithm to remove you from the shortlist for your dream job. A retailer might use the data to single you out for a higher price online. A political group might microtarge­t you with personalis­ed disinforma­tion.”

An Interactiv­e Advertisin­g Bureau spokespers­on said: “We have not been served with any documents in the case. We will review the allegation­s in conjunctio­n with our legal advisers and will respond in due course, if appropriat­e.”

Mr Ryan said that the bureau “sets the rules that govern Google and Facebook and the entire online advertisin­g industry” adding the new lawsuit will “force the online ad industry to stop tracking everyone online”.

He added the action had come “after three years of inaction by GDPR enforcers”.

RTB is enormously lucrative, with Google’s ad exchange alone generating revenue in the region of €20bn in just three months in 2018.

Most of the profiling which precedes online advertisin­g auctions follows templates produced by the IAB. Those templates can allegedly tell where you live, as well as other informatio­n such as age, hobbies and interests and even health issues.
