Identity Resolution for Marketing AI: Deterministic, Probabilistic, Gr

Identity resolution connects interactions across devices and channels to a unified profile. As cookies fade, AI infers connections using consented signals and probabilistic methods within strict boundaries.

Deterministic first. Prioritize hashed emails, logins, and CRM keys. M

Probabilistic carefully. Use device features, network patterns, and behavioral similarity with regularization and conservative thresholds. Favor household-level resolution when person-level certainty is low; disclose assumptions.

Governance and transparency. Provide opt-out, data access mechanisms, and purge policies. Enforce consent checks before activation; separate storage for sensitive attributes.

Frequently asked questions

What is identity resolution?

Identity resolution connects interactions across devices and channels to a unified profile, enabling marketers to understand their customers better. This process becomes increasingly important as traditional tracking methods like cookies decline in effectiveness.

How does AI handle identity resolution without cookies?

AI utilizes consented signals and probabilistic methods to infer connections when traditional tracking is unavailable. This involves analyzing device features, network patterns, and behavioral similarities while maintaining strict boundaries and conservative thresholds.
