• A Future Built on Decentralized Identity 2021-12-22 Bloom

  Decentralized identity is an emerging concept becoming more popular for online consumers by eliminating the need to pass personal identifiable information (PII) to an ever-increasing number of companies. However, in practice, decentralized identity has only existed for a handful of years, and its potential is still being discovered. So how did we get here?

• Introduction to Decentralized Identity IOTA Wiki

  Decentralized Identity or Self-Sovereign Identity (SSI) defines a new method for identity management and authentication. It removes the centralized aspects and puts the Identity subject in full control over its own identity. Decentralized Identity provides a solution for the increasing amount of database breaches, the lack of trust in any digital setting, and the increasingly difficult to comply with privacy legislation, such as GDPR.

• Self-Sovereign Identity: Shifting the Locus of Control 2019-03-02 Tim Bouma

  Simply put, the old (centralized and federated models) the locus of control was between the other parties that could make decisions about me, whether I was in the picture or not. In the new model (self-sovereign identity), the user is put into the centre of his/her own locus of control. See above.

• The Three Models of Digital Identity Relationships — How self-sovereign identity (SSI) is different, and why it’s better 2018-08-24 Timothy Ruff, Evernym

  SSI is powerful yet elegant, bold yet familiar, and through it we can finally break free from the paradox of having to sacrifice security for user experience (or vice versa): we can have both, and at levels vastly improved over the status quo. Wonderfully, SSI also has life-altering potential for at-risk populations around the globe.

• Inevitable Rise of Self-Sovereign Identity 2018-03-28

  The evolution of internet identity is the result of trying to satisfy three basic requirements:

  1. Security - the identity information must be protected from unintentional disclosure;
  2. Control - the identity owner must be in control of who can see and access their data and for what purposes;
  3. Portability - the user must be able to use their identity data wherever they want and not be tied into a single provide

• The Implications of Bring Your Own Identity Identity Defined Security Alliance 2020-12-03

  My short stint as “Mark Jannell" taught me a lot of about trust and ease of use in a bring your own identity model. Trust, as always in security, is essential to this new class of relationships and must be established and then protected from abuse. Ease of use, it turns out, is a key factor in protecting that trust and promoting the adoption of good identity patterns. I’m sure that I could have learned these lessons in some other way, but I’ll never forget my half year answering to a pseudonym.

• What is the Trust Triangle? 2021-08-23 Affinidi

  The relationship between the issuers, holders, and verifiers is called the trust triangle simply because you need an element of trust among these entities for them to work together.

• A Primer on Functional Identity 2017-08-26 Joe Andrieu rwot05-boston

  Unfortunately, digital systems can unwittingly compromise real-world identity. Sometimes this occurs because digital identity systems neglect to consider external effects. Other times, it happens with systems that didn’t even realize they were dealing with identity-related personal information. A functional perspective allows engineers to see beyond static attributes and traditional notions of “Personally Identifiable Information” to better understand how engineering choices can impact identity, even outside their systems.

• What is decentralized identity? 2022-07-06 CSO Online

  The DID model allows you to establish a relationship between your private key (your blockchain wallet) and your citizenship.  The issuing authority signs off on the truth of your claim and, thereafter, third parties can check your public key to see that the holder of the private key is in fact a British citizen.

• Security, Silos, and Sovereignty 2021-03-12 Daniel Hardman

  Why portable security is the sleeper — but killer — feature for SSI

  what’s cool about DIDs (besides their self-service creation) is that their metadata is cryptographically verifiable. That means that anyone in the world can tell whether the metadata is legit, in the blink of an eye, just by asking software to check some math. And it also means that you can build a transport-independent, tamper-proof, encrypted communication channel with whoever controls a DID.

Literature

• [WhitePaper] Self Sovereign Identity 2022-05-10 Phil Windley, Blockchain Research Institute

  In this research, one of the leading experts and thought leaders in the digital identity space brings his latest thinking to enterprise innovators. He explains the value of the relationship view of identity, the nature of authentic digital relationships, the trust bases of identity systems, and the architecture of the identity metasystem, including decentralized identifier communication and the self-sovereign Internet. He then explores how to operationalize digital relationships and the potential of generative identities (e.g., verifiable credentials) and credential exchange. He concludes with a deep dive into self-sovereign identities in production: the UK National Health Service staff passport, Bonifii’s MemberPass for credit unions, the International Air Transport Association Travel Pass, and others. The project is a must-read for enterprise leaders looking to understand their opportunities in identity platforms and applications.

• [Whitepaper] Self-Sovereign Identity Foundations, Applications, and Potentials of Portable Digital Identities 2021-09 Fraunhofer Institute for Applied Information Technology FIT

  This paper analyses the SSI paradigm's conceptual characteristics and technical aspects and presents three use cases as examples. It becomes clear that SSI offers advantages in individual control, data security, and full portability of identities between different services. For example, forgeryand tamper-proof digital versions of important personal documents such as ID cards, passports, birth certificates or medical confirmations can be created. However, the use cases are not limited to personal SSI but can also be, for example, digital identities of organizations and physical objects in the context of IoT solutions. This is particularly important in connection with the comprehensive digitization of companies.

• Digital identities – steps on the path to an ID ecosystem 2021-03-18 Bankenverband This article is very very good in articulating the big picture of how SSI systems relative to older system and emerging fragmetned systems.

  An answer to these challenges is an ecosystem in which digital identity data can be exchanged in a way that is secure, reliable, scalable and convenient. This will have a positive impact on the economic future of Germany and Europe while at the same time enhancing the private sphere of the individual.

• The Path to Self-Sovereign Identity 2016-04-25 Christopher Allen Popularized the concept of Self-Sovereign Identity

  Since then, the idea of self-sovereign identity has proliferated. Loffreto has blogged how the term has evolved13. As a developer, he shows one way to address self-sovereign identity: as a mathematical policy, where cryptography is used to protect a user’s autonomy and control. However, that’s not the only model. Respect Network instead addresses self-sovereign identity as a legal policy; they define contractual rules and principles that members of their network agree to follow14. The Windhover Principles For Digital Identity, Trust and Data15 and Everynym’s Identity System Essentials16 offer some additional perspectives on the rapid advent of self-sovereign identity since 2012.

• A Technlogy-Free Definition of Self-Sovereign Identity 2016-10 Joe Andrieu

  This paper explores what self‐sovereign identity means independent of technology: what people need from independent identity capabilities. I want to understand how such a system enables both individuals whose identities are in play (subjects), as well as those who use those “identities” to correlate interactions across contexts (observers). I start with grounding individual sovereignty in the Enlightenment and identity in its core function of correlation, then propose core characteristics of a self‐sovereign identity system.

• 10 Principles of Self-Sovereign Identity 2016-10-23 Rebooting Web of Trust

  1. Existence. Users must have an independent existence. Any self-sovereign identity is ultimately based on the ineffable “I” that’s at the heart of identity. It can never exist wholly in digital form. This must be the kernel of self that is upheld and supported. A self-sovereign identity simply makes public and accessible some limited aspects of the “I” that already exists.

• Schutte's Take 2016-10-26 Rebooting Web of Trust (criticism of the 10 principles)

  A perceived sense of “a self” is the product that emerges from the interactions of these various agents.

  Their coherent operation takes form in the world in ways that enable other actors to treat them as if they were a single actor rather than the complex set of collaborations amongst different processes that they actually are.

  Of course, this is a heuristic, and like all heuristics, it may be a useful shortcut, but that doesn’t mean it accurately reflects reality.

  In truth, our “self” is constantly interacting with agents both externally and internally, and these transform the functioning (and even the perceived boundaries) of the self.
