Subject: Re: Secure Chrome

One of the crowd pleasers of Microsoft's Infocard pitch is the secure  
user experience. If you were to have Microsoft's Infocard show static  
HTML rather then a fixed UI, it would seem that you would have Secure  
Chrome. The user knows it is the their secure browser because it  
initially shows a graphic secret shared between the user and the app.  
The keyboard and screen are locked out to any other app to block  
malware. Unfortunately the UI is fixed.

Microsoft did significant user experience research in designing  
Infocard in order to stop phishing. It could be worthwhile to review  
what they learned.
