## CS2 Player's Master's Thesis
A Counter-Strike 2 player developed a system using behavioral biometrics to identify players based on mouse and keyboard use.

> Bans hit accounts, so cheaters just make new ones
## Behavioral Biometrics System
The system compares mouse and keyboard behavior across match demos to determine if two accounts belong to the same person.
## Testing Results
Mouse fingerprints correctly identified players 100% of the time across 1,000+ players, while keyboard fingerprints did so 98% of the time.
## Identifying Smurfs
The system uncovered previously unknown smurfs by separating known same-player pairings from unrelated accounts.
## Correct Pairings
After adding discovered accounts, the system correctly identified all 13 known same-person pairings.
## Future Implementation
The system could work with VAC and Trust Factor to ban cheaters permanently, but requires testing at scale and account linking as evidence.
## Key takeaway

A Counter-Strike 2 player developed a system using behavioral biometrics to identify cheaters across accounts, potentially banning them forever instead of just accounts.
