Scottish public bodies have identified more than £110m of fraudulent or mistaken payments since they began sharing data nearly a decade ago.
Audit Scotland co-ordinates the data-sharing exercise every two years.
It includes matching electoral registers against households receiving single-person tax discounts to see if others are living at the address.
The latest National Fraud Initiative (NFI) in 2014/15 uncovered nearly £17m of fraud and error.
