Fair Isaac Offers Identity Protection for Telecom Providers.

Fair Isaac provides telecommunications carriers with protection from identity fraud by combining the company's industry-standard fraud detection capabilities with valuable new data sources and the most advanced analytic and investigation methodologies. It will help carriers more effectively spot identity theft in applications for service, continually monitor call records and account activity for signs of fraudulent activity and pinpoint early indications of bad debt.

Today's announcement follows the results of a recent telecommunications industry survey involving major U.S. carriers, who cite identity theft as the industry's top fraud-related issue. Sponsored by the Telecommunications Risk Management Association (TRMA), a leading industry trade organization that helps its members reduce fraud and uncollectibles, the survey represents the first step in a major campaign aimed at identifying and deploying 'best practice' fraud management through collaboration and education among major telecommunication services providers.

"Telecom service providers are increasingly challenged by a new generation of technologically savvy fraudsters," said Ted Crooks, vice president of Identity Protection Solutions at Fair Isaac. "Identity frauds today are more sophisticated, numerous and dangerous, and combating fraudsters successfully while protecting customer convenience and avoiding misidentification requires a higher level of technology and cooperation then ever before. Having led the advancement of fraud protection technologies for more than a decade, Fair Isaac is the right company to help the industry stop this blight."

Through access to cross-industry consortium data, patented modeling and profiling technologies and innovative investigative techniques, Fair Isaac's ID Fraud Protection initiative will enable telecom carriers to quickly detect inconsistencies in the information provided on an application as well as identify similarities between individual applications and known fraud patterns.

"Leading telecom service providers, financial services and retailers around the world have been successfully using Fair Isaac's solutions to identify risk and prevent fraud with the utmost reliability for many years," said Tony Zarrella, Fair Isaac's director of Telecom Risk Solutions. "Our new solutions build on our standard-setting, advanced technologies and proven expertise to arm providers with the next generation tools to protect themselves and their valued customers against ID theft. Telecom carriers will realize a significant reduction in the amount of identity fraud seen in the pre-and post-activation stages."

More than 100 telecommunications providers worldwide, including eight of the top 10 U.S. wireline providers and all of the top 10 U.S. wireless providers, currently use Fair Isaac technology to improve business decisions in acquisitions, originations, fraud and account management.
