I definitely remember that being sold as one of the plus points, and that's what it says on wikipedia, but I didn't get far following the references to see whether it was true in practice.<br /><br />Dan Brown thinks not, but I wanted to check before seeing if I could count it as a "mistake".<br /><br /><b>Security</b><br /><br />Am I right that having a biometric scan without any human oversight is inherently risky? I don't know how hard retina scans are to fake, but am I right that the implicit idea of biometric identification is that you need to (a) check that you submit the right biometric and (b) check that that biometric really belongs to the person standing there. And that (b) can be done by a human guard, or by an automated system, but just assuming that it will magically happen without any effort may work sometimes but isn't inherently secure as long as fingerprints are on the <i>outside</i> of our bodies?<br /><br /><img src="https://www.dreamwidth.org/tools/commentcount?user=jack&ditemid=780992" width="30" height="12" alt="comment count unavailable" style="vertical-align: middle;"/> comments https://jack.dreamwidth.org/780992.html retina scans security public 0
