Self Sovereign Identity

  • What is Self Sovereign Identity 2021-10-13 Florian Strauf

    The important thing in SSI is that instead of a stamp on the plastic card, the credential is signed cryptographically by the issuer, enabling anyone to verify who issued the credentials. This makes verification much easier than in the physical world.

  • #SSI gives its owner control over some aspects of identity, but not all 2021-12-14 Jolocom

    Connections, relationships, and third-party issued credentials are not entirely self-sovereign, nor should they be. #JolocomAdvent #AdventCalendar

  • What are Verifiable Credentials? Why do they matter? 2022-01-10 Fluree

    Authority Does Not Require Centralized Power

    As mentioned in my previous article, the trouble with centralization is that data is stored in a database. Once breached, a database can yield a treasure chest of information to be sold on the dark web.

  • The Decentralized Identity Schelling Point 2023-03-01 Sarah Baldeo

    Back to the Schelling Point - communication requires a common language and understanding. As governments, banks, hospitals, etc. navigate how best to homogenize authenticating user identities in multiple contexts, solutions will depend on user adoption. Maximizing adoption requires avoiding a Schelling point by creating a shared, accessible, and evolving Decentralized Identity Lexicon.

    • Natural persons and legal entities interact in the digital world with the same freedom and capacities as in the offline world (e. g. signing, authorizing documents, validating signatures, communicating privately etc.)
    • Data is stored privately on a user device and not replicated numerous times across the digital world.

    In other words, when a user “shares” data, it shares only the access to his/her data. And, as easy as one can do that, they can also revoke it (unless they are legally bound to share it for a certain period).

  • 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.

  • Evolution of Self-Sovereign Identity (SSI) 2021-11-16 LionsGate

    The public keys of the user and the third-party organization for verifying the digital signature are recorded in a distributed ledger, and the user of the identity information verifies the provided information using them. In this way, users can control their own identity information without relying on a specific central administrator.

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.

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.
