To the uninitiated, the whole concept of digital identity can be difficult to understand. We all get what user accounts are and a bit about how they can be leveraged—thanks to the internet and social media—but for many of us, they’re just basic tools that we use, and we put little thought into what makes them run. We may have an idea of what goes into maintaining an identity (things like names and passwords), but no real knowledge of the inner workings.
But digital identity is all around us in daily life, and understanding how it works can help us think about identity in a new way and gain insight into how digital identity concepts can relate to one another. So, as someone who thinks about identity (a lot), I was struck by how identity concepts bear a striking resemblance to models and concepts found in physics.
