Introduction
Today losses in the telecommunications industry are estimated to more than $30 billion a year. Telecommunication companies use many techniques to combat fraud. Fraud management systems are the most powerful and irreplaceable tools that large companies use to combat fraud.
One of the techniques that are used in fraud management systems is the so-called “link analysis”. It helps fraud agents to visualize the behavioral patterns of subscribers using collected info in database. This gives fraud agents the opportunity to detect unknown members of a fraudster organization, trace mobile devices or SIM cards used in fraudulent activities, create subscriber profiles, etc.
Main goal & functionality
Let's describe the main functionality required for a Link Analysis Tool - a module that can later be incorporated in a Fraud Management System.
To enable an easy integration, the tool must be accessible
using standard web browsers without the need for additional proprietary client side software.
The main functionality of the tool is to visualize transactions (call detail records data read from a database table) in a defined period of time and with a defined search depth (who called whom) for a given subscriber.
