The global media and advertising industry runs on identity.
Over decades, an enormous ecosystem has evolved around identifiers that enable organizations to recognize consumers, connect data, activate audiences, and measure results.
These identifiers have become deeply embedded in the technologies and workflows that power the industry, creating significant commercial value.
But as first-party data becomes increasingly strategic, there's an important question worth exploring.
Shouldn't organizations control how their own customer identities are connected across the ecosystem?
The Identity Ownership Paradox
Publishers, retailers, advertisers, and data providers invest heavily in building direct relationships with their customers.
They own the relationships. They collect and govern the data. They carry the responsibility for protecting it.
Yet, to make that data interoperable, they frequently rely on identifiers minted and maintained by third-party identity providers.
These identifiers become the common language through which customer records are recognized and connected across organizations.
An organization may own its customer data while depending on someone else to control the identifiers that connect it to the rest of the ecosystem.
And because those identifiers often persist across transactions, they can also create opportunities for information to accumulate around recognizable individuals, increasing the potential for re-identification over time.
As organizations seek greater control over their first-party data, it's worth reconsidering whether this dependency must remain a fundamental requirement for collaboration.A Future Built on Greater Control
What if organizations could collaborate across the data ecosystem while retaining independent control of their customer identities?
Imagine an environment where identity owners determine how, when, and with whom their customer relationships are connected. Where partnerships can be established without creating long-term dependencies on identifiers controlled by third parties.
This would give organizations greater freedom to explore new partnerships, expand existing relationships, and realize more value from their first-party data, while reducing unnecessary identity persistence and the risks that accompany it.
The existing identity ecosystem represents decades of investment and integration. Its role in global advertising is firmly established, and any evolution will take time.
But new approaches can complement established systems, gradually expanding the choices available to identity owners. For organizations paying volume-based ID solution fees, shifting workloads to alternative approaches may also reduce costs along the way.
For organizations operating in privacy-sensitive markets, the transition is already beginning. Growing demands for stronger data protection, greater control, and reduced identity exposure are making alternative collaboration models an increasingly practical choice.
The future of identity interoperability is taking shape around a simple principle: organizations should be able to collaborate while maintaining control of their customer relationships.
