* [The Architecture of Identity Systems](https://www.windley.com/archives/2020/09/the_architecture_of_identity_systems.shtml) by Phil Windley 
    > I recently read a paper from Sam Smith, [Key Event Receipt Infrastructure](https://arxiv.org/abs/1907.02143), that provided inspiration for a way to think about and classify identity systems. In particular his terminology was helpful to me. This blog post uses terminology and ideas from Sam's paper to classify and analyze three different identity system architectures. I hope it provides a useful model for thinking about identity online.

  > - Algorithmic
  > - Autonomic
* [Authentic Digital Relationships](https://www.windley.com/archives/2020/08/authentic_digital_relationships.shtml),   
  > Self-sovereign identity, supported by a heterarchical identity metasystem, creates a firm foundation for rich digital relationships that allow people to be digitally embodied so they can act online as autonomous agents.

* [Self-Sovereign vs Administrative Identity](http://blogs.harvard.edu/vrm/2012/03/25/ssi/) Doc Searls 2012
  > The problem I’m trying to surface here is that we need full respect for self-sovereign identities, and identifiers, before we can solve the problem of highly fractured and incompatible administrative identifiers — a problem that has only become worse with the growth of the Web, where by design we are always the submissive and dependent party: calves to administrative cows.

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.

  > What we’d like to highlight in this simplified process is the fact that it is the user who stores the claim and anchors it on chain. Also, because it is a private claim, the contents are provable but not disclosed. The user can therefore prove that they have been granted a certain privilege, but unless they elect to disclose this information, it is impossible for a third party to find out.

  > 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.

We pointed to this before it happened. It was great. Here is a round up from Jolocom. It is highly recommended.

> The paper Decentralised Identity: What’s at Stake?. Answering the paper’s core question of what’s at stake, it gives three essential scenarios:
> 1. Ideal – full convergence of SSI technology with interoperability by default.
> 2. Functional – partial convergence resulting in detached ecosystems.
> 3. Dysfunctional – no convergence and isolated, locked-in ecosystems.
* [Who Controls Your Digital Identity?](https://blogs.sap.com/2021/02/18/who-controls-your-digital-identity/) SAP
  > SSI will have to be integrated with large existing business processes – and therefore enterprise systems such as ERPs, HCMs, or SCMs to name a few. If this integration results in SSI being as easy to use as clicking a button or selecting a menu item, it will lead to rapid uptake and acceptance.
* [The 5P’s of a Self-Sovereign Identity](https://markvanrijmenam.medium.com/the-5ps-of-a-self-sovereign-identity-e6f6eb802d75)
  > A self-sovereign identity can be defined by the 5P’s as it is personal (it is about you), portable (meaning you can take your identity and data from one platform to another), private (you control your identity and data), persistent (it does not change without your consent) and protected (they cannot steal your identity).
* [Benefits of SSI and Blockchain in Digital Identity](https://www.good-id.org/en/articles/benefits-of-ssi-and-blockchain-in-digital-identity/)
  > The needs and experiences of citizens are established with how digital identity networks should preserve the freedoms and rights of users over the needs of the network. Transparency is explicitly mentioned as part of SSI, and it places a high emphasis on the importance of the public’s trust.
  > 
  > As we look to the future of digital identity, SSI principles with blockchain have already proven to be successful by bringing together stakeholders to create a mutually beneficial network.

Second, the issuer gets a trusted, open and transparent way to publish the cryptographic material needed for those private holder-verifier transactions. Third, there is no need to have a “Trusted Third Party” participating in the interactions.

Identifiers, DID, ion

- Decentralization of did:ion if anchoring transactions are batched by an operator: it’s possible to choose the operator or to incur the cost of anchoring the transactions. Furthermore, the operator doesn’t gain access to the private key.
- ION delivers: massive scale, cost efficiency (despite running on the bitcoin network - best case if bitcoin a transaction costs 100 USD one action costs 1 cent), decentralized & flexible, decentralized registries
- ION has a type system so that DIDs can be used, e.g. for software packages, vehicles, … This makes it possible to make the centralized data repositories that we rely on today, npm registries etc., to be fully decentralized. This is a Sidetree feature that is currently only used by ION.
- DIF is currently working on personal data stores. Expected impact on private messaging, social media, gig services, ..
- ION is live and in production today
- Ion-tools is a selection of tools to interact with the ION network: [https://github.com/decentralized-identity/ion-tools](https://github.com/decentralized-identity/ion-tools)
- Resilience of ION: It’s pointed out that not only Bitcoin needs to survive attacks but also the IPFS network as both are required for ION to work properly. With Bitcoin it looks unlikely that it’s currently possible to reverse transactions on the network. However, with IPFS data can be unpinned and potentially disappear from the network.

Self-sovereign identity Definition <-its quite good

Self-sovereign identity (SSI) is rooted in the belief that individuals have the right to an identity independent of reliance on a third-party identity provider, such as the state or any other central authority. Its implementation requires the development of technical standards, as well as socio-political adaptations rooted in legal amendments in order to be successful.

* [#SSI101: An Introductory Course on Self-Sovereign Identity](https://medium.com/spherity/ssi101-an-introductory-course-on-self-sovereign-identity-the-spherity-way-19e0d1de3603) Spherity

Outside of a few philosophers, social scientists, and a tiny minority of specialized technologists, however, most people feel uncomfortable making any definitive or authoritative statements about identity.

Decentralized digital identities are only possible due to cryptography. One of the cornerstones is asymmetric encryption. A key pair is generated using a cryptographic process. The pair consists of a public and a private key. As the names suggest, the private key must remain private and the public key can be shared.

Guests include Brian Behlendorf, Rainey Reitman, Danny O'Brien, Sarah Friend, Wendy Hanamura, Andrew Hill, and Brad Kam.

## (the) Use Case

* [Impact of Self-Sovereign Identity on Cybersecurity](https://securityboulevard.com/2022/04/impact-of-self-sovereign-identity-on-cybersecurity-avast/)

Great explainer - infominer

How does this change the world of cybersecurity protection? Typically, bad actors approach cybersecurity attacks by developing solutions that exploit the attack vectors of their target victims.

There are 4 attack vector categories to self-sovereign identity that map directly to each element: Issuer, Holder, Trust Registry and Verifier.

* [SteveWilson](https://twitter.com/Steve_Lockstep/status/1524073204805160960) Considering SSI critics

I reckon most cases of over-identification stem either from bad habits (e.g. RPs gathering circumstantial AuthN signals) or from Surveillance Capitalism. Either way, better deals for users will come from better design, not by weaponising Digital Identity (SSI, DIDs).

* [Understanding Verifiable Credentials](https://credivera.com/understanding-verifiable-credentials/) Credivera

The value of verifiable credentials and the critical role they will play to our future digital identities is undeniable. As we enter a new era of online representation, trust in the internet will need to be vigorously robust.

In “Self-Sovereign Identity,” [Johannes Sedlmeir](https://www.fim-rc.de/Paperbibliothek/Veroeffentlicht/1359/wi-1359.pdf) makes a clear distinction between two concepts too often mixed: “identity” and “identifiers”. What we are experiencing in today’s Web are some external organizations identifying us as citizens, community members, customers, etc. But this isn’t our “identity.” Those are identifiers.

* [Myths about SSI](https://jolocom.io/blog/myths-about-ssi/) Jolocom

The idea that as a user of SSI I have complete sovereignty over my digital identity is often misunderstood. At its core, SSI is about my digital identity being under my own control, so I can decide to whom I show my data, when, and for what.

Decentralized identity (DID) is a way for users to own their identity, using specific credentials to verify their identity to applications. These credentials, called Verifiable Credentials, enable you to do this. Verifiable Credentials are identity attestations that come from a trusted issuer, like proof of a workplace, student IDs, or official memberships.

This series is intended to be a basic, easy-to-understand introduction to SSI, but for a much deeper dive, check out Hypersign Labs — our technical blog. Here’s a good place to start on SSI:

* [Digital Identity: Past; Present; Future](https://labs.hypersign.id/posts/ssi-intro/) Hypersign

As a result of limited and known users there was no layer of identity and authentication in the design of internet framework. With the invention of the World Wide Web (WWW), the users made it a common platform for data sciences. Various sectors of society like health and finance have started using the internet for their services.

* [What Is Self-Sovereign Identity?](https://trinsic.id/what-is-self-sovereign-identity/) Trinsic

Eventually, SSI will give people a super simple way to do the following and more:

1. Protect sensitive identity information like SSN and birthdates to reduce the likelihood and impact of identity theft
2. Securely prove your identity or things about yourself in a way that institutions can trust
3. Maintain privacy and reduce the ability for corporations or nefarious actors to track you without your consent
4. Conveniently get access to services you need without usernames and passwords
* [Crossfunctionality](https://docs.centre.io/blog/crossfunctionationality) Centre

I have developed a pet peeve for "technosolutionism": the notion that a sufficiently innovative technology can solve a social problem, or a business problem, without complex and nuanced changes to social and business practice.

* [What does ‘open’ mean to you?](https://blog.weareopen.coop/what-does-open-mean-to-you-cec90dff6845) WeAreOpenCoop

Even with a little bit of input and discussion, you can see the shift to words such as ‘inclusivity’ and phrases such as ‘being more accessible’ or ‘getting everyone involved’.

* [The Self-Sovereign Identity (SSI) Basics](https://santandergto.com/en/the-self-sovereign-identity-ssi-basics-what-is-it/) Santanderigo

The very center of the digital identity is your documents: from your National ID or Passport to your degrees, mobile phone number, bank account number, or your medical records. Anything that is intrinsically bound to you is your data and therefore your identity. While talking about SSI these are called Verifiable Credentials (VC).

* [What is decentralized identity?](https://www.csoonline.com/article/3665692/what-is-decentralized-identity.html) In CSO

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.

Most are probably not "written" in the normally understood sense of the word (auto-scraping and ctrl-c and ctrl-v isn't writing). Many are probably not written by a person at all.

The two main ingredients of SSI are verifiable credentials (VCs) and decentralized identifiers (DIDs).

* [According to](https://www.w3.org/TR/vc-data-model/) W3: "Verifiable credentials represent statements made by an issuer in a tamper-evident and privacy-respecting manner."

No other additional information is needed to complete this data exchange. So how do you know that the information being provided is authentic? The identity ‘proof’ uses a cryptographic hash function that confirms beyond any doubt that the identity claim is accurate.

The public keys, as the name implies are there to view anytime and are used for exchanging information and can be revoked, however, the private key is for the account holder himself, be that an issuer, a verifier, or a subject. It is only through a private key that one can pass on his credentials using his DID to an issuer who then validates the credentials and sends them to the verifier using his DID.

issuers or verifiers can only access the information shared by the DID holder. This information exchange can occur through [various technologies, like NFC](https://nftnewstoday.com/2022/10/03/nft-applications-in-the-supply-chain/), QR, or Bluetooth. [Zero-knowledge proofs](https://nftnewstoday.com/2022/09/15/immutable-x-layer-2-scaling-solution-for-nfts/) are applied to restrict full information access.

That way, your sensitive personal data is stored locally on your own device rather than hosted on some company’s server that becomes a target for hackers.

Oldie but Goodie by Kim Hamilton Duffy from when she worked at Learning Machines

Technically, Verifiable Claims are claims made about a “subject” (identified by a digital identifier such as a DID) that are rendered tamper proof through digital signatures. The authenticity of digital signatures may, in turn, be established through issuer identifiers, which may also be expressed as DIDs.
