Can EXIF Data Be Faked?
Yes. EXIF data can be edited or completely fabricated using tools like:
- ExifTool (command-line)
- Adobe Photoshop
- Exif Pilot
This means EXIF data alone cannot be used as definitive proof of when/where a photo was taken in legal contexts.
EXIF vs XMP vs IPTC
Three types of photo metadata:
- EXIF: Technical camera data (automatic)
- IPTC: Descriptive data (caption, keywords, copyright)
- XMP: Adobe's extensible metadata standard (combines both)
