To get <i>informed</i> consent you would have to communicate that this involves every picture taken being uploaded to Facebook servers (but not posted to your Facebook account) to be scanned for friends. Even that &#x27;uploaded but not posted&#x27; distinction would be difficult to convey to a lay person.<p>I&#x27;m not sure hiding that in an &quot;About privacy&quot; section would get a reasonable level of informed consent either, very few would read it.<p>This is an issue that keeps coming up: useful features involve slurping a lot of personal data in order to do the processing remotely, that distinction is not understood by a large number of the users and explaining it fully is determined to be bad UX (&quot;overly technical explanation&quot;) and bad marketing (makes the privacy implications obvious).
