I was going through one of the articles on camera fingerprinting that says that

using most basic Instagram or Snapchat filters will not get rid of the camera fingerprint. However, changing the resolution, which most social media sites do, or blurring and then deblurring the photo will scrub your picture of this camera fingerprint.

If these are true then is there any evidence or research work that explains these specific cases in a more elaborated way for a better understanding of the way the whole thing works?

Also, how can I defend my photographs on social media from being fingerprinted?

  • I believe they are incorrect that changing resolution and such can get rid of fingerprints. Some camera fingerprints are very resilient, for example ones involving chromatic aberrations. If I recall correctly, you would not only have to reduce the resolution considerably (not just change, but reduce), as well as drastically decrease the color depth. – forest Jan 10 '18 at 7:37
