Question 1

What is identity resolution software?

Accepted Answer

Identity resolution software identifies and connects records that belong to the same person across databases, applications and business systems. It uses exact, fuzzy, probabilistic and evidence-based matching to recognise customers even when their information is incomplete, inconsistent or duplicated.

Question 2

What is the best identity resolution software in 2026?

Accepted Answer

It depends on your requirements. WinPure Clean & Match Enterprise v12 suits no-code cleansing, matching and golden record creation. Tilores and Senzing suit real-time, API-driven resolution; Informatica, Reltio and IBM Match 360 suit enterprise Customer 360 and MDM; LiveRamp and Amperity suit marketing identity and activation; AWS Entity Resolution suits AWS-native teams.

Question 3

What is the difference between identity resolution and entity resolution?

Accepted Answer

Identity resolution focuses on people and customers. Entity resolution is broader and also covers organisations, suppliers, products and other entities. Both use similar matching techniques.

Question 4

What is the difference between deterministic and probabilistic identity matching?

Accepted Answer

Deterministic matching links records using predefined rules on identifiers such as customer IDs or emails. Probabilistic matching weighs the combined evidence across several fields to estimate whether records belong to the same person. Most platforms combine both.

Question 5

What is the difference between identity resolution and identity verification?

Accepted Answer

Identity resolution decides whether different records refer to the same person. Identity verification checks that a person is who they claim to be, usually with documents or biometrics during onboarding. They serve different purposes and can complement each other.

Question 6

How does identity resolution support Customer 360?

Accepted Answer

It connects fragmented customer records across systems so they can be combined into one unified profile. Accurate matching is essential: missed matches leave profiles incomplete, and false matches combine different people&#8217;s data.

Question 7

What is the difference between real-time and batch identity resolution?

Accepted Answer

Real-time resolution matches records as they arrive, for live applications. Batch resolution processes whole datasets, for CRM deduplication, migration and cleansing. Many organisations use both.

Question 8

Can identity resolution software process millions of records?

Accepted Answer

Yes, though performance depends on the engine, data, configuration and hardware. In an internal test, WinPure v12 processed approximately one million records in 14.6 seconds using a six-column fuzzy and exact matching configuration; this was not independently verified.

Question 9

Is AI-powered identity resolution secure?

Accepted Answer

It can be, depending on deployment, access controls and data handling. Check where personal data is processed, what is sent to external AI services and how matching decisions are audited. WinPure AIConnect works with selected metadata and matching information rather than requiring full customer datasets to be sent to a language model.
