Anti-Fraud & Bot Detection System

A three-layer defense system for registration forms that detects bots while minimizing false positives for legitimate users.

Architecture Overview

Layer 1: SERVER-SIDE (tamper-proof)
├── Encrypted timestamp token verification
├── Device fingerprint matching
└── Minimum fill time enforcement (3s)

Layer 2: MANIPULATION DETECTION (server comparison)
├── Client vs Server timing mismatch
├── Keystroke/input inconsistency
└── Impossible value detection
