Need felt by insurers to shift away from traditional fraud detection methods and adopt advanced analytics techniques
Traditional fraud detection methods Automated/Analytics driven techniques
Traditional methods such as internal audit, ‘Red Flag’ indicator, and scoring model, among others, primarily detect known fraud patterns using sampling techniques
Since these methods require manual intervention, there is a higher possibility of human error and longer lead times from fraud detection to the settlement of claims
Traditional approaches are also known for high false-positive rates (flagging genuine claims as fraudulent), which impact customer satisfaction

The advent of Big Data is further changing the fraud detection and investigation dynamics
Insurers mostly analyze structured data, which represents just 15-20% of the total data that is generated by them
– This data is mostly historical in nature and lose its predictive power beyond a certain point
Insurers need to adopt robust fraud management techniques that enable real-time fraud detection by efficiently and effectively processing large volumes of structured and unstructured data

However, very few insurers have deployed fraud detection and prevention techniques using Big Data analytics
Planning Knowledge Gathering Pilot Deployment
Set plans to guide project teams throughout the adoption phases
Determine the investments and anticipate benefits from such projects
Take into account existing and untapped in-house sources and assess the requirement of additional data types
Run pilots to determine the feasibility of such projects and its impact on organizational goals
Analyze benefits realized and run pilots again in case project fails to produce expected results
Ensure that departments exposed to Big Data analytics have understood associated governance and risk management practices
Ensure organizational requirements are in place such as integration of the siloed data; additional resources to handle higher work volumes; added capacity to store, maintain, and manage such data
