Duplicate prevention

Put processes in place to prevent, identify and correct duplicate records, identities, requests or claims.

This control targets both internal and external fraud risks.

Examples

Examples of this control include: 

  • identifying and denying duplicate claims
  • flagging and reviewing potential duplicate vendor invoices
  • requiring employees to undertake thorough searches of existing customer records to avoid creating duplicate records
  • interrogating systems to identify, review and correct potential duplicate records.

Risks from control gap

Duplicate records, identities, requests or claims can lead to:

  • fraudulent payments being made multiple times
  • dual claiming of different payments or benefit types
  • duplicate or ghost records being used to conceal activities or exploit processes
  • incorrect and inconsistent reporting and decision making
  • other control weaknesses, e.g. less-effective fraud detection.

Assessing effectiveness

Methods to evaluate the effectiveness of this control include:

  • confirming that clear and consistent processes exist to prevent, identify and correct duplicates
  • analysing data to confirm duplicates are being properly identified and corrected
  • consulting subject matter experts on processes
  • conducting a system or process walkthrough by having employees show you the process for managing duplicates
  • reviewing a data sample to confirm compliance with policies and processes
  • reviewing who has access to review and correct duplicates
  • checking if and how duplicates are reported.
