Bot detection is the set of techniques websites use to tell automated traffic apart from real human visitors. It combines signals like IP reputation, fingerprints, and behavior to block scrapers and abuse.
Browser fingerprinting identifies and tracks a device by combining dozens of browser and system attributes — like fonts, canvas rendering and user agent — into a near-unique signature.
Canvas fingerprinting is a tracking technique that uses the HTML5 Canvas API to draw hidden graphics and measure tiny rendering differences unique to your device. These differences form a stable identifier used to track and detect users.
A CAPTCHA is a challenge–response test used to tell humans and bots apart, such as identifying images or checking a box, to block automated access.
A Cloudflare challenge is a verification step that Cloudflare shows visitors it suspects are bots before allowing access to a site. It can range from an invisible check to an interactive puzzle.
