Our friends at Smartex challenged its readership to define Digital Identity the other day, with a bottle of wine on offer for the best definition. I’m pleased to say that the bottle of wine was won by Consult Hyperion, with a couple of competition entries submitted.
Coming up with a definition for digital identity is not easy. It can refer to quite a number of different things, making the task of encapsulating it in a sentence next to impossible. For my attempt I thought that rather than try to describe what it is, it would be better to describe what it does. I came up with this:
Digital identity allows us to trust each other by enabling us to share the minimum amount of verifiable information needed for the thing we want to do.
In one sentence I was trying to capture several points:
- Digital identity is a means to an end not an end in itself
- It’s bi-directional – in any transaction both parties need to have confidence in the other party
- It’s about the information you need to share, which will vary considerably between contexts.
- It protects privacy by only sharing the information (or claims) necessary.
