Multi-modal deepfake detection analyzing spatial steganography, spectral frequency distributions, and audio-visual temporal synchronization.
Drag and drop, paste from clipboard (Ctrl+V), or browse. Verified via MAPF-Lite neural architecture.
Zero Customer Retention
Media is automatically deleted after 24 hours.
GDPR Salted Privacy
Raw IP addresses are never logged or stored.
No Model Training
Your media is never used to train or tune AI.
Engineered with a zero-knowledge ingestion pipeline that protects your privacy while delivering sub-second results.
Before uploading, your browser computes a SHA-256 hash using chunked Web Workers. Previously analyzed viral clips return full forensic reports in under 50 milliseconds without consuming compute.
On cache miss, your video streams directly to an isolated Azure Blob container via short-lived SAS tokens. Media is strictly purged after 24 hours by enforced cloud lifecycle deletion rules.
Frozen CLIP and Whisper backbones guided by learned prompt tokens inspect high-frequency spatial gradients, producing calibrated probabilities and an Audio-Visual Temporal Radar report.
Generic detectors overfit to facial expressions. MAPF-Lite interrogates physical, spectral, and temporal anomalies.
Spatial Rich Model (SRM) 5x5 Kernels
Fixed high-pass steganographic filters suppress facial semantics to highlight boundary interpolation artifacts, color-blending seams, and double-compression ghosts left by FaceSwap models.
Discrete Cosine Transform Decomposition
Generative networks (GANs and Diffusion architectures) leave non-natural frequency decay curves and periodic grid artifacts in the frequency domain that are invisible to the naked human eye.
Cross-Modal Cosine Coherence (S_AV)
Aligns speaker phonemes with lip-motion visemes across 16 frames. Authentic recordings maintain high sync (S_AV ≥ 0.78), while LipSync models trigger sharp desynchronization dips (S_AV ≤ 0.42).
DeepShield was built under the strict tenets of GDPR Article 25 (Privacy by Design). Uploaded videos are stored temporarily in a private vault with public access completely disabled, and are automatically, irreversibly deleted after 24 hours.

In accordance with EU AI Act Article 13 transparency principles, DeepShield publishes where our detector excels and where it has known vulnerabilities:
Extreme Low Bitrate
Aggressive video compression (e.g. sub-500 kbps viral re-encodes) can destroy high-frequency SRM residuals.
Heavy Analog Noise
Vintage VHS tape grain or simulated camcorder static can introduce artificial high-frequency noise bands.
Unseen Generative Models
Brand-new proprietary diffusion architectures with novel latent spaces may require updated prompt embeddings.
Probabilistic Evidence
Scores represent calibrated mathematical probabilities, never absolute judicial proof. Always corroborate with context.
Never. Uploaded media is transferred via direct SAS URL to an isolated Azure Blob container with public access disabled. An automated lifecycle policy permanently destroys all video files after 24 hours. We never train or fine-tune models on your data.
Your browser computes a cryptographic SHA-256 fingerprint before uploading. If someone has already submitted that exact video, the forensic report is fetched from our edge Redis cache in ~50 milliseconds, bypassing upload and compute entirely.
DeepShield provides probabilistic forensic analysis based on state-of-the-art neural methods. Under EU AI Act Article 13, our reports must be considered expert evidentiary indicators, not certified proof. Always conduct human expert review for critical proceedings.
We accept MP4, QuickTime (MOV), and WebM containers up to 100 MB. For optimal speed, clips between 5 and 30 seconds containing clear speech and facial visibility are recommended.
