The explosion of social media has opened a vast new trove of information — true and false — for people to express themselves and learn about the world.

In doing so, it has created an entirely new channel of communication for scammers that perpetrate fraud, and also for insurance companies to discover fraudulent claims.

For instance, consider the case of a California corrections officer who filed for disability benefits due to a back injury. Two days later, he participated in a mountain bike race, a fact that was discovered after Facebook posts, his headcam videos and race standings appeared online. He served 45 days in jail and paid a $5,000 fine.

In another case, a newlywed collected $26,500 after claiming she lost her wedding ring while swimming in the ocean. Suspicion arose when, a few months later, her husband also reported losing his ring valued at $14,000. Soon thereafter, an investigator found the wife's picture on Facebook showing her with the ring. The insurer recovered its money.

The eternal battle between fraudsters and their victims plays out daily in the industry, since some studies suggest that as much as 10 percent of all property and casualty claims contain fraudulent elements, according to the Insurance Information Institute. Social media investigatory techniques must continuously improve to stay a step ahead of those with malicious intent, since perpetrators constantly develop new angles of attack.

The sheer volume of information now available, however, poses both the greatest opportunity and challenge for insurance companies. One billion new social media posts appear every two days, according to consulting firm Infosys' report “Big data analytics: New whistleblower on insurance fraud.” How can a company possibly digest all of this information? The answer involves teamwork, a clear approach and big data analytical tools.

The right team

Leveraging social media to fight fraud requires a unique breed of investigator who can understand how the data available fits into the context of a larger investigation. They must be proficient in adhering to legal and procedural requirements, identifying subjects correctly and examining case documentation and public records before starting a social media search.

Due to the highly specialized nature of this role, forward-thinking organizations often engage select vendors that maintain teams of investigators with social media search capabilities.

Clear objectives

To avoid getting lost in research blind alleys, social media investigators must choose what questions they want answered and be mindful of where they may be able to develop additional leads. For example, did an accident happen as reported? Is a business still operating successfully? Who or what is the subject connected to and what may that connection reveal?

Text-mining software

This tool can parse and analyze unstructured text-based information. It has already been helping investigators examine internal claims data such as adjuster notes, emails, service calls and interview records. Top claims operations are using text-mining tools to search Facebook, LinkedIn, YouTube, Twitter and other social media sites.

Predictive modeling

Catching fraud in its earliest stages is one of the best ways to minimize loss, especially if it is discovered before significant funds have been paid. Predictive modeling can act as a powerful aid in supporting this objective. It looks for common patterns that indicate an increased possibility of fraud, allowing insurance companies to investigate sooner and often achieve a faster case resolution rate.
