<p><strong><a href="http://www.cronto.com/technology.htm">Cronto</a></strong></p> I saw a demo of this the other day—it’s a neat anti-phishing scheme that also protects against man in the middle attacks. It works using challenge/response: an image is shown which embeds a signed transaction code; the user then uses an application on their laptop or mobile phone to decode the image and enters the resulting code back in to the online application. <p>Tags: <a href="https://simonwillison.net/tags/challengresponse">challengresponse</a>, <a href="https://simonwillison.net/tags/cronto">cronto</a>, <a href="https://simonwillison.net/tags/maninthemiddle">maninthemiddle</a>, <a href="https://simonwillison.net/tags/openid">openid</a>, <a href="https://simonwillison.net/tags/phishing">phishing</a>, <a href="https://simonwillison.net/tags/security">security</a>, <a href="https://simonwillison.net/tags/signing">signing</a></p>
