TeliaSonera International Carrier (TSIC) has implemented an automatic proactive fraud detection service for the benefit of its international voice customers, based on a solution from IPsoft, a provider of fraud management and big data application services. A press release explains: ‘As international voice services move away from a physical circuit switched environment, detecting new methods of fraud such as deliberately extending call duration, or sending calls to automated message platforms, becomes an increasingly important issue. TSIC is taking steps to protect its customers and their end users using IPsoft functionality which performs statistical analytics to identify the source of the fraud, enabling TSIC to take action and maintain the integrity of its service.’ Ravi Dube, CTO at IPsoft, elaborated further: ‘We originally developed our autonomic system to learn the patterns of falsely answered calls for major enterprises and have been very pleased with the interest shown by TSIC in tackling the problem at source. We had a very successful trial which demonstrated that the non-invasive technology worked perfectly, finding fraud without false positive alarms and its results underpinned a solid business case.’ The solution uses a self-learning set of statistical and big data algorithms developed by IPsoft; false answers are detected and patterns indicating fraud are detected in real-time. IPsoft claims ‘98% accuracy levels’ for its solution, which scales to 500 million calls per day.
