What is Device Fingerprinting?
Device fingerprinting identifies a visitor by the combination of attributes their browser and device expose, rather than by cookies or IP address alone.
How it works
Signals like canvas rendering, installed fonts, timezone, and hardware concurrency combine into a stable identifier that survives proxy rotation.
Why it matters for sportsbooks
Fingerprints let you recognize the same operator across thousands of IPs, which is where scrapers and botnets are weakest. For your book, that means margin on every market stay protected and bettors get a fair experience.
How OddsArmor detects it
OddsArmor scores every request against behavioral, network, and device signals, so automated patterns surface even when they imitate real bettors. Suspicious sessions get challenged or blocked before they reach your book.
