Phil Wainwright says that the issue isn’t digital identity, it’s digital title. Actually, they’re related — identity gives you access to the owned information.
Phil goes on to comment extensively on Doug Kaye’s earlier posting about the risks of centralized digital identity systems.
In two short sentences in that essay, Doug succinctly nails the fundamental flaw in all of these systems: “Who says consumers want a network identity? Why is that a good thing? I suggest it’s unwanted, unnecessary and dangerous.”
By encouraging individuals to concentrate all their digital title into a single digital identity, we’re asking them to commit one of the cardinal sins of secure systems. Single sign-on is a massive single point of failure.
