Today, people are sharing more personal information than
ever before – whether for online banking purposes, to verify billing
information or to buy new products – heightened activity has meant that Fraud
Detection in Telecommunications is at the top of the priority list.
Telecommunications companies are striving to create a more resilient fraud detection system due to severe financial losses. It has become more challenging to keep up with fraudsters as they sporadically migrate from one carrier to another. Blacklisting numbers is no longer an effective means of keeping hackers under tight restrictive movement – with hackers easily evading the detection by changing their numbers through VoIP.
To heighten the screening method, the content of a call
rather than the number itself is being monitored carefully to reverse the
increasing levels of fraudulent activity. Machine learning algorithms are being
used to analyze data and select high quality descriptions from previously
collected data. The formation of new rules come as a direct result of taking
such data and extracting the necessary information to help construct flags in
the system when a detection has been made – based on detecting textual data
that is similar to previously recorded fraudulent activity.
To achieve tighter security measures online, an android
application can be installed on a customer’s smartphone so that when an
incoming fraud call is intercepted, the application can efficiently identify
frauds by analyzing the content of the call. Natural language processing
techniques enhances the level of sensitivity of detection.
Unfortunately, hackers never fall too far behind an evolving
system – frequently finding ways to sabotage a network. Conventional feature
detection based simply on numbers is no longer reliable and can be easily
foiled by those who have infiltrated the carrier. What is needed is a stronger
level of client-related information to help strengthen security within the telecoms’
infrastructure – all too often, telecoms companies are providing general
information but not allowing for customer insight and feedback to fortify
The advances in technology and system information has
enabled the telecoms industry to step-up their security measures, however,
financial loss indicates that more work must be done to ensure that clients are
protected from fraudulent activity. Many new systems are being designed and
tested all over the world to improve data protection and security, but in the
rapidly changing tech landscape, the challenge merely intensifies.
With soaring living costs hitting the UK hard, the rise in bills is becoming increasingly noticeable and, for many, increasingly challenging to afford. That includes our broadband bills. Here, Guy Miller, CEO of full fibre broadband network operator, MS3 Networks, shares his advice on getting the best broadband deal. The cost-of-living crisis is affecting almost […]
