EXIF Metadata Extraction and Privacy Risks
Every photo from a smartphone embeds metadata: GPS coordinates, timestamp, device model, even the software used to edit it. This data persists through most sharing methods. In OSINT investigations, EXIF data can pinpoint where and when a photo was taken. In privacy assessments, it reveals what information users unknowingly share.

GPS coordinates accurate to a few meters, date and time of capture (including timezone), camera make and model, lens and exposure settings, thumbnail images (which may differ from the edited version), and software modification history. Some cameras embed serial numbers. Editing software may add its own metadata showing what was changed.
Geolocating images from GPS data, verifying photo authenticity by checking if metadata matches claimed location and time, identifying the device used to take a photo, and detecting manipulated images where EXIF timestamps don't match modification dates.

Security context
Before sharing photos publicly, strip EXIF data. Most social media platforms remove GPS data on upload, but email attachments, direct file sharing, and many websites do not. A single photo with GPS data can reveal someone's home address, workplace, or daily routine.
Frequently asked
Most photos from cameras and smartphones contain EXIF data. Screenshots, generated images, and images that have been stripped or re-encoded typically do not. PNG files support metadata but not the full EXIF standard. JPEG and TIFF are the primary EXIF carriers.
