What is data matching?
Data matching involves comparing computer records held by one body against other computer records held by the same or another body to see how far they match. This is usually personal information.
Computerised data matching allows potentially fraudulent claims and payments to be identified. Where a match is found it may indicate that there is an inconsistency which requires further investigation. No assumption can be made as to whether there is fraud, error or other explanation until an investigation is carried out.
