One idea that did catch my attention was the idea of ratings or stars based on authentication policy as the basis for a sort of trust, combining eBay-style (as was) community-based ratings with degrees of authentication to give a reasonably granular set of conditions under which identities may be accepted in different circumstances. If it were left to the market rather than, say, the European Commission, to determine pricing then one might assume that organisations and individuals would gravitate to the appropriate level for their transaction.
What does this mean? Well, it means that you wouldn’t ask for someone’s ID card and fingerprint authentication when all you want to know is whether they are over 18 or not (because it would cost too much). But it also means that you might often support quite important decisions (eg, shall we let this person into our World of Warcraft guild) on the reputation attached to their digital identity within a community — not necessarily your community, but a community that you trust — rather than an external reference (eg, the government) or rating system.
I used that example because a Gartner survey of 4770 internet users across the world found web users spend most of their online time on email, followed by information gathering; internet banking; sharing photos and videos (in effect, social networking); maps and transport information; and online shopping. Pretty much as you would expect, because that mirrors your usage. But when you look at the online habits of 13 to 18 year olds, a different picture emerges: they spend their time in communities of one kind or another, communicating with each other (and I know, from first hand experience, that they communicate comfortably through a variety of identities). Whereas we (ie, older persons) are stuck in a paradigm of external authentication and “ranking”, younger persons are not, so they naturally adjust to the idea that identity is not something granted by authority but constructed in a communities and transmitted between them.
So back to my hobby horse. We need to create identity infrastructure for the future, not the past, and trying to treat identity in the modern age as an electronic representation of pieces of cardboard, issued by one public authority and read by others, cannot possibly support individuals, business, organisations or, for that matter, governments in the 21st century.
