Screen-recapture & moiré detection
How Claimscan detects this
- Pixel forensics
Pixel forensics detect moiré interference patterns and sub-pixel grids characteristic of photographing a display.
- Metadata
A 'photo of a photo' usually lacks the camera MakerNote and capture fields a genuine in-hand shot would carry.
- Reverse image search
Reverse image search can locate the original on-screen image that was re-captured.
- MakerNote
Absent or inconsistent MakerNote data weakens the claim that the photo came straight from a phone camera.
Frequently asked questions
What is a moiré pattern and why does it matter?
Moiré is the wavy interference you see when a camera photographs a pixel grid (a screen). Its presence is a strong indicator that a 'photo' is actually a picture of a display, not a direct capture of a real object.
Is missing metadata proof of fraud?
No. Many legitimate workflows strip metadata. It is one indicator among several — Claimscan weights it accordingly and never treats it as a verdict.
