Our take
This research offers a potential solution to the persistent problem of ban evasion in CS2 by linking accounts to human behavior rather than just digital identifiers. The high accuracy rates reported in the thesis, particularly the 98% success rate for keyboard biometrics, suggest a viable path for future anti-cheat integration.
Background
Cheating remains a persistent issue in online shooters like Counter-Strike 2, where banned players often create new 'smurf' accounts to return to the game immediately. Existing anti-cheat systems like Valve Anti-Cheat and Trust Factor struggle to link multiple accounts to a single human user, allowing repeat offenders to evade permanent bans.
Christopher B. Didriksen, a student at the Norwegian University of Science and Technology, sought to address this gap by researching biometric identification methods. His work focuses on the unique ways individuals use their mouse and keyboard, aiming to create a system that can identify the human behind an account regardless of the specific account name or hardware settings.

PC Gamer reported on Didriksen's thesis findings
Didriksen's master's thesis, which proposes a biometric system to identify CS2 players based on their mouse and keyboard usage patterns. The report highlights that the system reportedly successfully identified players in a dataset of over 1,000 users, with mouse biometrics allegedly identifying players 'every time' and keyboard use reportedly picking out the right player 98% of the time.[1]
Our read of the evidence
Mostly unverified. The only information about the system comes from a PC Gamer article dated October 9 2026 that describes Didriksen's thesis; no primary source such as the thesis itself or university records has been cited to confirm the details. Because the claim rests on a single report and lacks independent verification, the evidence remains mostly unverified.
Our rating counts evidence, not opinions about anyone: events confirmed by a primary source (the person's own post, their official site, a court or government record) weigh most, then how many independent outlets report the story.
Frequently asked
Is the CS2 biometric tracking system implemented by Valve?
No, the system is currently a master's thesis project by Christopher B. Didriksen. According to PC Gamer, the thesis is finished and received an A grade, but there is no statement from Valve regarding its implementation.
How does the player tracking system work?
The system analyzes mouse and keyboard movement patterns to create a unique 'fingerprint' for each player. According to the thesis findings, this fingerprint stays stable across different maps, sessions, and even changes in mouse sensitivity.
What is the accuracy of the biometric identification?
In a dataset of over 1,000 players, mouse movement biometrics correctly identified players every time, while keyboard use picked out the right player 98% of the time. Cross-referencing these metrics identifies the humans behind the accounts with a high rate of accuracy.
Can this system detect smurf accounts?
Yes, the system is designed to identify repeat offenders and smurfs. According to Didriksen, the method found smurfs that nobody had reported and is fast enough to check every new match against all of CS2's monthly players.
