Risks in IAB Europe’s proposed consent mechanism

Dr Johnny Ryan GDPR

This note examines the recently published IAB “transparency and consent” proposal. Major flaws render the system unworkable. The real issue is what should be done with the vast majority of the audience who will not give consent.  Publishers would have no control (and are expected to blindly trust 2,000+ adtech companies) The adtech companies[1] who drafted the IAB Europe proposal claim that “publishers have full control over who they partner with, who they disclose to their users and who they obtain consent for.”[2] But the IAB Europe documentation shows that adtech companies would remain entirely free to trade the personal data with their business partners if they wish. The proposed system would share a unique[3] consent record “throughout the online advertising ecosystem”, every time an ad is loaded on a website:[4] “the OpenRTB request [from a website to an ad exchange] will contain the entire DaisyBit [a persistent cookie],[5] allowing a vendor to see which other vendors are an approved vendor or a publisher and whether they have obtained consent (and for which purposes) and which have not.”[6] There would be no control over what happens to personal data once they enter the RTB system: “[adtech] vendors may choose not to pass bid requests containing personal data to other vendors who do not have consent”.[7] This is a critical problem, because the overriding commercial incentive for many of the companies involved is to share as many data with as many partners as possible, and to share it with parent companies that run data brokerages.…

Can websites use “tracking walls” to force consent under GDPR?

Dr Johnny Ryan GDPR

This note examines whether websites can use “tracking walls” under the GDPR, and challenges the recent guidance on this issue from IAB Europe.  This week, IAB Europe published a paper that advises website owners that tracking walls (i.e., modal dialogs that require people to give consent to be tracked in order to access a website) will be permissible under the GDPR. Our view is different. Several months ago we provided feedback to the IAB of what we regarded as serious mistakes in a preliminary draft of this paper, which we believe will be very detrimental to publishers who follow the paper’s advice. As it appears that our feedback did not make it into the published version of the paper, we want to put our opinion on the record, so that publishers can take it in to account when deciding what course to follow under the GDPR.…
