Keyboard Dynamics
Inter-key intervals, dwell time, flight time, and error correction rate create a behavioral fingerprint for every session.
Behavioral intelligence, production ML inference, and automated policy enforcement — built into one verification layer for modern applications.
DETECTION
CertiLayer passively captures behavioral features across keyboard, mouse, touch, scroll, and motion — without storing raw behavioral data.
Inter-key intervals, dwell time, flight time, and error correction rate create a behavioral fingerprint for every session.
Velocity, acceleration, curvature, and micro-adjustments reveal patterns that are extremely difficult to reproduce consistently at scale.
Touch dynamics, swipe velocity, tilt, and orientation capture the physical characteristics of real human interaction.
Velocity patterns, direction entropy, and scroll depth expose behavioral differences between humans and automated sessions.
Page transitions, focus duration, and decision latency create a temporal behavioral fingerprint for each session.
Raw signals are transformed into feature vectors immediately. No keystrokes, cursor coordinates, or sensitive raw events are stored.
ML PIPELINE
The Human Continuity Engine processes behavioral signals through a multi-stage ML pipeline to produce a Human Confidence Score from 0.0 to 1.0.
Instantly rejects obvious automation signals such as headless browsers, missing browser APIs, and impossible timing patterns.
Behavioral identity verification using BiLSTM embeddings. Keyboard evaluation reaches an AUROC of 0.9673.
Bot-versus-human classification across the canonical 34-feature vector with a reported validation AUROC of 0.9993.
Per-modality anomaly detection catches sessions that appear human while exposing subtle behavioral inconsistencies.
Weighted scoring combines M3 and modality-specific anomaly signals into a single Human Confidence Score.
ONNX inference runs CPU-only. Warm inference targets sub-5ms latency without requiring a GPU or external ML service.
POLICY ENGINE
Decide what happens after CertiLayer evaluates a session — from frictionless access to silent tarpitting or immediate termination.
High-confidence sessions pass through instantly with zero additional friction.
Add a configurable delay to suspicious sessions. Humans barely notice while automated clients waste time and resources.
Require WebAuthn or OTP when a grey-zone session attempts a sensitive or high-value action.
Route suspicious automation into an isolated environment with controlled data for behavioral analysis.
Immediately invalidate sessions below your configured threshold and prevent further access.
Configure endpoint-specific policies so high-risk actions can enforce significantly stricter verification.
