OSINT Image & Video Verification 2

Question 1

Which metadata field in a JPEG's EXIF data most directly reveals the GPS coordinates where a photo was taken?

Accepted Answer

GPSLatitude and GPSLongitude tags

Answer

The GPSLatitude and GPSLongitude EXIF tags store the precise coordinates embedded by smartphones and GPS-enabled cameras at the moment of capture.

Question 2

An analyst suspects a video was recorded at a different time than claimed. Which visual cue in the footage could help establish the actual time of day?

Accepted Answer

Shadow length and direction relative to the sun's position

Answer

Shadow length and direction can be cross-referenced with solar calculators to determine the approximate time of day and season a video was recorded.

Question 3

What does the term 'metadata stripping' mean in the context of image verification?

Accepted Answer

Removing embedded EXIF/IPTC data before sharing a file

Answer

Metadata stripping removes embedded information such as GPS coordinates, device identifiers, and timestamps from image files, often to protect privacy or conceal origin.

Question 4

Which technique involves overlaying a satellite or map image on top of a photo to confirm the depicted location matches the claimed site?

Accepted Answer

Geospatial cross-referencing

Answer

Geospatial cross-referencing aligns visual landmarks in a photo with satellite or street-level imagery to confirm or refute a claimed location.

Question 5

An OSINT analyst finds a viral photo allegedly from a recent protest. Performing a reverse image search returns results dated three years earlier. What does this most likely indicate?

Accepted Answer

The image is recycled from an older event and may be misrepresented

Answer

Earlier reverse image search dates strongly suggest the photo pre-dates the claimed event, indicating possible misattribution or deliberate reuse of old imagery.
