About Podcast Episode

Thinking of identity systems as foundations of relationships can help us understand how and when we should be using them.

“The architectures of traditional , administrative identity systems do not reflect the fluid multi – pseudonymity of real life , so they are mismatched with how people actually live .” (Windley, 2023)

I recently read Phil Windley’s new book, “Learning Digital Identity: Design, Deploy, and Manage Identity Architectures” (available here), and I highly recommend it to any listeners of this podcast. The book elegantly distills down the most important concepts of digital identity. As I read, I found myself taking copious notes and making new associations between concepts that I hadn’t made before, leading to a flood of new ideas.

This conversation expands nicely on the one Phil and I had on the SSI Orbit Podcast in 2021 (here), and inspired my recent blog post “Offering Outputs, Not Restrictions”. I hope you enjoy it as much as I did.

In this podcast episode with Phil Windley, we discuss,

  • The differences in our knowledge needs between the physical world (tacit) and the digital world (explicit) are what make digital identity management complicated.
  • Short-lived vs. long-lived relationships: a comparison.
  • If the real world has pseudonymous relationships, why can’t this be true online? (looking at recent Twitter and Meta verified account initiatives)
  • Does the role of Identity Providers (IdPs) change as we move towards more user-controlled systems, rather than administrative identity systems?
  • How does the term “Relying Party” translate into SSI?
  • Breaking down trust and trustworthy, and differentiating between confidence and trust.
  • Examining the tradespace between Privacy, Authenticity, and Confidentiality.
  • How attribute-based access control (ABAC) will benefit from verifiable credentials.
