Integrated Fraud Detection System
The Integrated Fraud Detection System (IFDS) is a traffic analysis system that employs user-defined parameters to detect and report suspicious activity on any telecommunications network. IFDS is a high functionality system specifically developed to meet the needs of telecommunications businesses.IFDS provides the ability to set thresholds and raise alarms on many aspects of a subscriber's calling pattern. The subscriber's activity such as volume of calls, total value, total duration, numbers called etc are monitored and scored. A cumulative scoring system is used where alarms are prioritized and presented as highest scoring first. The alarms are then forwarded to the case manager which handles case creation and workflow assignment.
IFDS also has a very powerful inference engine that allows inference rules to be defined on any combination of data fields within a CDR record and any field in the billing system extract (if this option has been implemented). This allows for rules to be configured / adapted to trap existing, emerging and future fraud scams. This is a very powerful and flexible piece of functionality but does require the billing information interface to be installed.
The system has the flexibility to perform fraud analysis on Accounts, Subscribers, Calling (A) Numbers and Called (B) Numbers. This means for example that if a group of subscribers belonging to the same account exceed a certain spending limit then an alarm could be raised, even if the individual subscribers do not exceed their individual limits. Also, the B number analysis is useful for premium rate fraud detection.
IFDS has the following software application modules for detecting fraud:
- ALARM BROWSER - This is a Rule Base Engine for setting definable filters and thresholds. The module gathers the processed information and makes comparisons with Fraud scenarios established within the chosen filter parameters and prefixed thresholds. When preset thresholds are reached, an alert is generated and appropriate intervention can take place.
- CASE BROWSER - Fraud investigation tool for in depth and enhanced fraud follow-up and analysis. The module organises Fraud data in case type records. The stored case information is easily accessible for follow-up on corrective action taken at each stage until the event file is closed.
- REPORT BROWSER - This essential tool enables configuration of static and dynamic reports and their effective presentation in a wide range of tabular, textual and graphical formats. Report generation can be automatically scheduled or manually generated.
- PROFILE BROWSER - This tool builds detailed typical Behavior profiles for individual subscribers and generates reports if serious deviations from the normal behavior values occur.
