Verification
In the Tella settings, users can activate "Verification Mode". When activated, every time a user takes a photo or a video, or records audio, Tella automatically captures metadata (data about the file). This metadata can be used to corroborate evidence, cross check with other facts known about the event or about the area where it was captured.
