The Auditor General requires us to take part in a data matching exercise to prevent and detect fraud. This involves comparing computer records – usually personal information – to see how closely they match. Computerised data matching allows fraudulent claims and payments to be identified.

We must provide certain sets of data to the Auditor General for matching. Details can be found on the Wales Audit Office website.

A match may show an inconsistency which requires further investigation. No assumption can be made as to whether there is fraud, error or another explanation until an investigation is carried out.

As data matching is carried out by a legal body (Part 3A of the Public Audit (Wales) Act 2004) it does not need the consent of the individuals concerned under the Data Protection Act 1998.
