People who upload pictures with similar file names and matching lens patterns may be connected socially – or maybe they’ve never met or were at the same public event. Facebook has a patent on technology that identifies people who may know each other by analysing photo metadata and comparing dust and scratches on the camera lens.

These data can be useful if you have to find back or sort your pictures or video, but they can create risks by providing a lot of information about you and your behaviour to maleficent people or organisations.
