If you want to see even more identity graphs, have a look at this funky video by the facilitator of our E-learning 3.0 course (#el30), Stephen Downes:

He also offered a reasonably clear presentation about identity, keys and authentication. If identity, online and offline, is ultimately also about possibility, aspirations, hopes and dreams as much as about facts and connections, identity data seem valuable enough to be stored away in secure way, out of reach for big internet companies wanting to collect our data and for the authorities.

Immutable. Really?

Inevitably, in these discussions the blockchain is an important reference. Just as I have doubts about big corporates and the authorities, I don’t feel at ease with blockchain technology. As for now, the technology seems cumbersome and difficult to understand for non-geeks. It is often presented as a magical-technological solution for issues of trust and societal unease, which can only really be understood by the high priests of technology. But more importantly, even if it works and there are no hidden power grabs by opaque groups and experts, are we sure we want our identities being defined in an immutable way?

In the European Union quite some people embrace the right to be forgotten. What if at some point in the future, when my identity evolves, I really want to erase parts of my former identities? Maybe erasing and destroying parts of your identity is something constitutive of forming a new identity. While it seems relatively straightforward to erase social media profiles and blogs posts, and while it’s even possible to get Google to erase personal information about me, this would not be possible using the blockchain which promotes an immutable data storage which can not be tampered with. Or maybe I overlook certain possibilities of the blockchain which would allow for such ‘right to be forgotten’ – please let me know if this is the case!
