4. Biometric & Behavioral Interactions
Constant Scroll Speed
Detection approach
Scroll velocity is perfectly constant. Human scrolling exhibits acceleration curves, deceleration, and micro-corrections. A near-zero variance indicates scripted scroll injection.
How this helps detect bots
This signal is assessed with other independent session, browser, and network evidence. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.
Legitimate traffic to consider
Users utilizing the keyboard spacebar, page-down keys, or middle-mouse-button auto-scroll.
