\"\"<\/a><\/p>\n

Amongst the mass of privacy-first targeting and measurement solutions which have been vying for attention over the past two years, data clean rooms have stood out as some of the most promising.<\/span><\/p>\n

Clean rooms allow multiple parties to combine, match, and activate based on their first-party data sets, without any of those parties getting a look at anyone else\u2019s data. They offer a genuinely different way of using data in advertising; there\u2019s debate over how many \u2018post-cookie\u2019 solutions will survive the coming wave of privacy regulation, but data clean rooms seem to truly live up to their privacy-first rhetoric.<\/span><\/p>\n

But as with most jargon in ad tech, \u2018clean room\u2019 is something of an umbrella term, covering a range of subtly different technologies (or perhaps not so subtly in some cases, as tech companies slap a \u2018clean room\u2019 sticker on their products to capitalise on the current interest).<\/span><\/p>\n

Inevitably, this means there\u2019s a lack of interoperability between vendors, especially since many of these products are still quite young. And interoperability is a significant issue for tools which are specifically designed to facilitate easy collaboration.<\/span><\/p>\n

A proliferation of integrations<\/b><\/p>\n

As mentioned above, clean rooms are designed to allow data collaboration, without compromising data privacy.<\/span><\/p>\n

A basic example would be where one publisher and one advertiser want to combine their first party data sets for a new campaign. Maybe the advertiser wants to target existing customers with an ad for its newest product.<\/span><\/p>\n

In this case, both the publisher and the advertiser upload their first-party data sets into the clean room environment. Within the clean room, the two can then work together to match up data sets, target users, and report on the campaign. But crucially, the publisher never sees the advertiser\u2019s data, and the advertiser never sees the publisher\u2019s data. So far, so simple.<\/span><\/p>\n

Problems emerge as each publisher and agency tries to run similar collaborations with different partners, each of whom may already have their own preferred clean room vendor. Integrating with one clean room isn\u2019t too much of a hassle for an agency. Integrating with twenty different bespoke clean room setups for twenty different publishers and broadcasters is a bit of a headache.<\/span><\/p>\n

Interoperability would solve this problem, but currently \u201cthere isn\u2019t much established interoperability between platforms at all,\u201d according to Vlad Stesin, co-founder and CSO at clean room provider Optable.<\/span><\/p>\n

But that is starting to change, thanks to a mix of individual efforts and industry-level initiatives.<\/span><\/p>\n

Don\u2019t keep customers locked in<\/b><\/p>\n

For individual clean room providers, there are actually incentives to open up access for other clean rooms, and to not simply keep their customers locked into their own tools. Clean rooms, while powerful, take time to scale given the nature of the collaboration they facilitate.<\/span><\/p>\n

Taking a more open approach helps solve this problem. Optable\u2019s Stesin says interoperability has been a big focus for his own company. \u201cI have to say that Optable\u2019s emphasis on interoperability has created quite a bit of interest from other software vendors,\u201d said Stesin.<\/span><\/p>\n

Optable has taken a few approaches. One has been the launch of \u2018Flash Nodes\u2019, which let publishers invite any number of brands to their data clean rooms, without those brands having to be Optable customers.<\/span><\/p>\n

\u201cAnother component of our interoperable approach includes our open-source implementation of a cryptographically secure matching protocol,\u201d said Stesin. \u201cAny third party that wants to compare data with an Optable customer can use this utility to do so in a secure fashion. Given that the utility is open-source, anyone can vet the legitimacy and security of our approach.\u201d<\/span><\/p>\n

Stesin added that he expects other providers to follow suit. \u201cAs this segment of the ecosystem matures, we expect other vendors to adopt similar approaches in order to make sure that their customers aren\u2019t \u201clocked in\u201d and limited by the deployment scale of these vendors,\u201d he said. \u201cThe goal is to enable secure, privacy-preserving data collaboration no matter who uses which vendor \u2013 and do so while minimising data movement.\u201d<\/span><\/p>\n

Cutting out the manual labour<\/b><\/p>\n

Progress is also being made at the industry level, namely through IAB Tech Lab\u2019s work on standards for \u2018privacy enhancing technologies\u2019 – PETs for short.<\/span><\/p>\n

Benjamin Dick, senior director of product at IAB Tech Lab, said that clean room interoperability is a priority for the second half of 2022.<\/span><\/p>\n

\u201cBased on what we\u2019re hearing from the market, the initial focus of this work is to establish consistent data structures for clean room inputs and outputs,\u201d said Dick. \u201cFor example, if two organisations have different clean room partners that they\u2019d like to work together, these standards should reduce a lot of manual work involved in preparing data for ingestion, while also making the resulting computation easier to work with.\u201d<\/span><\/p>\n

Dick says that once this basic work is done, he expects further evolution to support more complex activations and use cases. \u201cGiven the increasing role that clean rooms will play in how data sets are joined to support purpose-limited targeting, measurement, and attribution – and the need for these use cases to be handled at increasingly faster intervals – we expect this work to evolve from basic use cases to more complex applications to support speed of activation,\u201d he added.<\/span><\/p>\n

So progress is being made. Nonetheless, progress may not be as quick as some would like – and there will inevitably be limits to how interoperable different solutions are.<\/span><\/p>\n

For a start, interoperability must be handled carefully. The core premise of a clean room is that data isn\u2019t passed freely between different partners, and movement of data is minimised. So any specifications which enable clean rooms to talk with each other have to ensure that no data is leaked in the progress. If this isn\u2019t the case, clean rooms\u2019 privacy credentials start to fall apart.<\/span><\/p>\n

And IAB Tech Lab\u2019s Benjamin Dick added that there are limits to how interoperable clean rooms will ever be.<\/span><\/p>\n

\u201cMarketplace competition will always produce efforts to build competitive advantage via proprietary features and product designs. As such, there\u2019s rarely perfect interoperability in a competitive marketplace, even with the most established technical standards\/protocols like Open RTB,\u201d said Dick.\u00a0<\/span><\/p>\n
