[LINK] Microsoft tests identity technology in schools

If you're going to attack this initiative, then you're going to have to 
get more focussed.  Microsoft's Information Cards are expressly all 
about supporting multiple identities, and do not involve a single global 
ID.  They have actually learned from the Passport mistakes.  In 
particular, Microsoft now is not an 'identity provider'.

I'm guessing in the schools pilot described, that an Info Card would be 
provided by the school concerned, corresponding to a set of local 
privileges.  Info Cards are not automatically portable through to other 
domains like university or the workforce; the expectation in the 
architecture is that you will get a fresh Info Card embodying specific 
claims/assertions when you join a new domain. 

In particular, if one Info Card was to hold your TFN, the architecture 
prevents other Info Cards from seeing it. 

So, Info Cards embody many properties that privacy advocates have long 
called for.  They're not perfect; for mine, they're deeply rooted in an 
'on-all-the-time' mentality, and could usefully be more de-centralised.  
But there's a lot of goodness there.
