The asymmetry of internet identity

The blog post by David Crawshaw explores the complexities and challenges of establishing and managing identity on the internet, likening it to a layered model similar to the OSI model for networking. The foundational layer begins with IP addresses, which are essential yet insufficient for identifying individuals. The next layer involves brands or domain names, which have evolved from traditional institutions to modern giants like Google and Facebook, relying heavily on DNS and TLS certificates for verification. The third layer concerns how brands recognize individuals, often through various methods like email or ID verification, depending on the brand's security protocols. The fourth layer involves the interaction between individuals via brands, where brands mediate communication and retain data within their ecosystems. The fifth layer introduces identity protocols like OAuth2, allowing cross-brand identity verification but adding complexity for users who wish to interact outside major platforms. The core issue highlighted is the asymmetry in internet identity, where people are dependent on a few identifiable brands for recognition and communication, posing challenges for individuals wanting to share small-scale digital creations without engaging in complex identity setups. The author suggests that a more user-friendly system should be possible, enabling easier sharing and interaction without relying heavily on large brands.
