Real-time Bot Detection

Behavioral Bot Detection.
Because Fingerprints Lie.

Detection Signals

Multi-Layer Detection

Analyze every aspect of user behavior to distinguish humans from bots with surgical precision.

Mouse Behavior

  • Teleportation detection
  • Velocity variance analysis
  • Path efficiency scoring
  • Jitter magnitude detection
  • Acceleration reversals

Scroll Behavior

  • Instant scroll detection
  • Chunk distance variance
  • Smooth scroll ratio
  • Events per chunk analysis
  • Velocity consistency checks

Form Behavior

  • Keystroke dynamics
  • Field completion timing
  • Paste ratio detection
  • Correction pattern analysis
  • Autofill vs bot detection

Fingerprint Intel

  • Session count tracking
  • Historical flagging ratio
  • Cross-session scoring
  • Cohort membership analysis
  • Headless browser detection

IP Intelligence

  • Tor exit node detection
  • Datacenter IP flagging
  • ASN reputation scoring
  • Geo-based risk assessment
  • Proxy detection

Proof of Work

  • Invisible challenges
  • Adaptive difficulty
  • Completion time analysis
  • GPU precompute detection
  • Rate limiting enforcement
Architecture

Three-Layer Defense

Unlike traditional bot detection that relies solely on static fingerprints, BotSigged provides adaptive risk scoring that evolves throughout a session.

1
On Connection

Initial Cohort Analysis

When a user connects, their fingerprint is analyzed to determine if they belong to a suspicious cohort.

  • > Canvas hash matching
  • > WebGL renderer analysis
  • > Font list fingerprinting
  • > Initial risk score (0-100)
2
Per Event

Behavioral Scoring

As events stream via WebSocket, the risk score dynamically adjusts based on behavioral signals.

  • > Mouse movement patterns
  • > Keystroke dynamics
  • > Scroll behavior analysis
  • > Real-time score updates
3
Background

Cross-Session Intel

Background processes identify new suspicious cohorts by clustering fingerprints and detecting patterns.

  • > Periodic cohort detection
  • > Temporal attack clustering
  • > IP pattern analysis
  • > Cohort updates & flagging
