Identity resolution matches a single customer's activity across multiple devices and touchpoints — a phone, a laptop, a tablet — into one unified profile, addressing the genuine challenge that a customer's behaviour is otherwise fragmented across seemingly separate, disconnected identities.
Deterministic versus probabilistic matching
Deterministic matching relies on a genuine, shared identifier — a customer logging into the same account across devices — offering high confidence and accuracy. Probabilistic matching infers a likely connection between devices based on behavioural patterns, offering broader coverage but with genuinely lower certainty and higher privacy sensitivity.
- Deterministic: high accuracy, based on genuine shared identifiers like account logins.
- Probabilistic: broader coverage, but based on inferred, statistically likely connections with inherently lower certainty.
A deterministic match is a fact you can verify. A probabilistic match is an educated guess dressed up with a confidence score — both have their place, but they deserve very different levels of trust in a major marketing decision.
Practical implications for marketing strategy
Deterministic matching, built around encouraging genuine account login and identification across touchpoints, provides the more reliable foundation for cross-device personalisation and measurement, while probabilistic matching should be treated as a supplementary, lower-confidence signal.
Privacy considerations specific to identity resolution
Probabilistic matching in particular raises genuine privacy questions given its inferential nature, making transparency about identity resolution practices and adherence to applicable consent requirements particularly important for this specific capability.
Frequently asked questions
How accurate is probabilistic identity matching typically?
This varies by the specific method and data available, but it is inherently less certain than deterministic matching — treating its output as a probability rather than a confirmed fact is the appropriate approach.
Does encouraging account login improve identity resolution meaningfully?
Yes, significantly — genuine deterministic matches from logged-in behaviour provide far more reliable data than any amount of probabilistic inference.
Is identity resolution affected by the same privacy changes as third-party cookies?
Yes, similar privacy-conscious constraints apply, making the first-party data strategy covered elsewhere directly relevant to building a sustainable identity resolution approach too.

The takeaway
Prioritise deterministic identity matching (a customer logging in with the same account) over probabilistic matching wherever possible — deterministic matches are genuinely more accurate and carry lower privacy risk than inferred, probabilistic device linking.
