  The research done in this study has delved deeply into the changes made to
digital images that are uploaded to three of the major social media platforms
and image storage services in today's society: Facebook, Flickr, and Google
Photos. In addition to providing up-to-date data on an ever-changing landscape
of different social media networks' digital fingerprints, a deep analysis of
the social networks' filename conventions has resulted in two new approaches in
(i) estimating the true upload date of Flickr photos, regardless of whether the
dates have been changed by the user or not, and regardless of whether the image
is available to the public or has been deleted from the platform; (ii)
revealing the photo ID of a photo uploaded to Facebook based solely on the file
name of the photo.
