DeadDetect API
Detection API that returns UID, confidence, and evidence for backend verification workflows.
What is DeadDetect
DeadDetect is the verification layer: upload media (or select from your library) and check whether a DeadMark payload is present.
It returns a practical result model: present / uid / confidence / evidence.

How it works
Two modes keep verification practical:
Normal Scan: fast checks for everyday moderation and platform monitoring.
Deep Scan: for severely transformed media where watermark recovery is weak. If UID decode is degraded, we compare recovered signal traits and media parameters against internal encode/decode logs, then output an attribution confidence score.
C2PA context can be used when available, but verification does not depend on C2PA alone.

AI roadmap: we are training additional models so Deep Scan can also estimate whether media is AI-generated even when no watermark is present.
Media evidence preview
DeadDetect is primarily used in backend and moderation pipelines, but operators still need clear evidence when a case is escalated. The same image / video / audio evidence overlay patterns shown below can be used in internal review tools and dashboards.

Dots show evidence-location visualization only (where payload-bearing evidence is distributed). Placement and strength are AI-driven / ML-adaptive per asset. The watermark itself remains invisible and does not appear as visible pixels.
Workflow note: C2PA + internal verification
We use C2PA where available and pair it with our own UID-linked watermark + log pipeline so verification is not dependent on a single metadata layer.
Roadmap signal
Text documents, plain text, and code watermarking/trace workflows are in active design, with public preview targets aimed for June 2026.
Scan modes
Normal Scan
- Fast and lightweight
- Best for routine checks
- Returns UID + confidence + evidence summary when decode is healthy
Deep Scan
- Used when watermark signal is severely damaged or transformed
- If UID is unrecoverable, compares media traits to internal logs and known parameters
- Outputs attribution confidence score and evidence package
- Roadmap includes AI-origin estimation for non-watermarked media
FAQs
You can, but you will not get UID-linked evidence unless content was encoded. For generic AI-origin classification, use a separate detector model.
