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 auto marketplaces
Fingerprints let you recognize the same operator across thousands of IPs, which is where scrapers and botnets are weakest. For your marketplace, that means your listing data stay protected and buyers and dealers get a fair experience.
How LotWall detects it
LotWall scores every request against behavioral, network, and device signals, so automated patterns surface even when they imitate real buyers and dealers. Suspicious sessions get challenged or blocked before they reach your marketplace.
