The mighty Vinay Gupta, incidentally (or not) co-founder of Edgeryders as @hexayurt, has published a very long-form piece on digital identity. Its added value is that it turns around the problem, trying different high-level approaches on for size. For example, blockchains (he muses) are secure now, but quite likely to be laughably insecure over the lifespan of a child born today. Money quote:
Many people sense huge economic opportunities from straightening up the identity mess and making things work, but we have to be sure the solutions proposed do not simply become the next generation of problems.
I am not buying 100% into his proposals (nor am I particularly qualified to), but, as far as I can see, he does have some good points.
What do you think, @RobvanKranenburg?
