Fake Original Photo

DOWNLOADABLE PNG photo. The file claims to be an 'original, unedited iPhone photo' but its EXIF metadata carries an image-editing tool signature (manipulation evidence) and GPS leaks the real capture location. Catch the metadata inconsistency, do not trust the forged claim.

Scenario

An evidence photo. The in-file comment says 'original, unedited' but the embedded EXIF (eXIf) metadata Software field contains an image-editing tool signature; that proves the photo passed through an editing tool (the claim contradicts the metadata). The EXIF GPS field carries the real capture coordinates. Skill: not trusting the surface 'original' claim; extracting the truth via metadata forensics (Software signature + GPS). Trusting the forged DateTime and calling it 'unedited' breaks soundness.

Anti-forensics techniques

Metadata forgery (forged 'original' claim)
Manipulation signature (EXIF Software field)
EXIF GPS location leak

Provided artifacts

PNG photo (embedded eXIf metadata)

Sample questions

q1: Which editing software proves the manipulation?
q2: Capture location from GPS (lat, lon)?
trap1: Do NOT report the photo as 'original / unedited'.

Soundness trap

The file plainly says 'original, unedited' and carries a forged DateTime; trusting it and reporting original is heavily penalized. The truth is the editing-tool signature in the EXIF Software field.

Scoring

Metadata forensic accuracy (manipulation+GPS) + forged-claim resistance (soundness).
