Project description

What we do and fight with:

The Profiler technology extracts more than 5,000 attributes about each user who enters an app to see if they are attempting to anonymise their actions, conceal their actual location, or use automation tools to deceive your business. The technology creates a complete profile of a user from declared and undeclared data the second he/she enters the mobile application. It’s an in-depth screening of a user who will no longer trick you with system emulations or spoofing. What’s important here is the fact that the Profiler is as powerful in screening mobile devices and applications as computers.     

4 groups of data gathered by the Profiler      

There are four main groups of in-depth attributes that Profiler delves into. However, the list is never final. The constant challenge is to develop new ways to screen users’ interactions with the website or application to understand them better and always be one step ahead of fraudsters.      

Hardware - This variable exposes the truth about the device itself (e.g. is the claim of a “mobile device” actually true or is this emulation?) and allows for precise fingerprinting.

Software and browser intelligence - Understanding the device’s software environment, plugins, applications, coherence of the setup, and use of fraudulent tools.      

Behavioral data - This attribute shows the user’s behaviour, how they interact with the application and device and is it a human behind it.

Network data - Everything related to the user’s internet connection, proxies, VPNs, and detection of various anonymisation techniques.
