Biological Signal Authentication

Deepfakes Can't Fake Biology

AI-generated videos are increasingly indistinguishable from real footage visually. But they fundamentally fail to replicate the subtle biological signals present in authentic human video — physiological patterns that our rPPG technology detects with high accuracy.

Our approach analyzes spatial coherence of blood flow signals across facial regions and temporal consistency over time — signatures that generative models cannot preserve.

Why Biological Signals?

Real faces have synchronized blood flow across regions
Deepfakes lack physiological spatial coherence
AI cannot replicate temporal pulse consistency
Works across all deepfake generation methods
Hardware-agnostic - standard cameras only

How Deepfake Detection Works

Our pipeline extracts and analyzes biological signals that authentic humans exhibit but synthetic media cannot replicate.

1

Face & ROI Detection

Computer vision algorithms locate the face and define multiple regions of interest (ROIs) across facial areas.

2

Biological Signal Extraction

Extract rPPG (remote photoplethysmography) signals from each ROI independently to capture blood flow patterns.

3

Coherence Analysis

Compute spatial coherence between regions and temporal consistency over time using signal transformations and correlations.

4

Verdict Output

API returns real or fake classification with confidence score based on physiological signal authenticity.

FakeCatcher: Biological Signal Authentication

Our approach builds on published research demonstrating that biological signals serve as robust authenticity priors for deepfake detection.

“FakeCatcher: Detection of Synthetic Portrait Videos using Biological Signals”

Ciftci, Demir, Yin — IEEE TPAMI (arXiv preprint)

Key Research Findings:
  • Generative models fail to preserve physiological spatial coherence across face regions
  • Temporal consistency of biological signals is absent in synthetic media
  • Pipeline: face detection, ROI mapping, signal extraction, coherence analysis
  • Signal transformations in time, frequency, and time-frequency domains
  • Cross-correlation analysis reveals authenticity signatures

Why Biological Signals?

Unlike visual artifact detection that can be defeated by better generators, biological signal analysis targets fundamental physiological properties that synthetic media cannot replicate.

Fraud Detection FAQ

Common questions about deepfake detection and identity verification

How does biological signal analysis detect deepfakes?

Real human faces exhibit subtle physiological signals like blood flow patterns (rPPG) that are spatially coherent across facial regions and temporally consistent over time. AI-generated videos fail to replicate these biological signatures accurately, allowing our system to distinguish authentic from synthetic content.

What types of deepfakes can the system detect?

Our technology detects face-swap deepfakes, face reenactment videos, fully synthetic AI-generated faces, and manipulated video content. The biological signal approach works across different generation methods because it targets fundamental physiological properties rather than visual artifacts.

How is the detection result delivered?

Results are delivered via REST API or native SDK integration. The output includes a real/fake classification, confidence score, and detailed analysis metrics. Integration typically takes 15-30 minutes with our documentation.

What video quality and length is required?

We require a minimum of 10-30 seconds of frontal face video at 720p or higher resolution with adequate lighting. Standard webcam or smartphone video quality is sufficient for accurate detection.

Is the system suitable for real-time video verification?

Yes, our system supports real-time analysis for live video calls and streaming content. Latency is optimized for interactive applications like KYC verification and video call authentication.
