Markup Detection

When to Use

Assess whether images or video show signs of tampering, compositing, or inconsistent capture metadata
Review documents (Office, PDF) for hidden markup, revision layers, comments, or undisclosed edits
Run metadata and provenance checks—EXIF/XMP, file hashes, embedded timestamps, export vs capture mismatches
Triage synthetic media and deepfake concerns using observable workflow indicators (not model training)
Interpret watermarks, C2PA / content credentials, and publisher attestation claims at a high level
Produce investigation memos with confidence tiers, evidence tables, and stated limitations
Compare source chain (original upload, reposts, screenshots) when authenticity is disputed
