I don&#x27;t agree that &quot;microsoft already does this&quot; - so don&#x27;t take what I&#x27;m about to say to mean that. I mean only to show a piece of technology that more directly relates to the comments others have made.<p>That being said, Microsoft has developed a piece of technology called PhotoDNA[0], which is designed with the specific purpose of identifying child pornography. This is actively used on OneDrive and Bing, among other services - including Facebook. It&#x27;s safe to say that OneDrive does not just delete the content if child pornography is detected - it reports to the authorities. Now, it&#x27;s hard to argue that they don&#x27;t have a right to do that, as long as the person is voluntarily using their services. That&#x27;s where I draw a distinction here: Facebook could elect to turn on PhotoDNA on photos uploaded to their new service, and not properly educate their customers that stuff is being uploaded automatically. This does, essentially, constitute a passive surveillance system. Mind you, if it is used to establish that child pornography is found, you will have a hard time convincing most people that it is overstepping what Facebook should do. That&#x27;s my concern - that this will be pushed as a &quot;for the children&quot; thing, and then extended to &quot;to cut down on crime&quot; later, once everyone stops caring about its existence.<p>That said, that&#x27;s my concern. It&#x27;s not necessarily what I think will happen. I have no reason as of yet to believe that it&#x27;s the next step. I do not, however, want Facebook automatically uploading (or even scanning) my photos.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;PhotoDNA" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;PhotoDNA</a>
