MyData was this week!

It was fantastic. Kaliya was part of the opening plenary and organized a session about the Origins of Identity and participated in a session on Sustainable Self-Sovereign Agents. 

They also have a post proposing Data Exchange Board to Improve the EU Data Governance Act

Scaling the personal data economy, MyData 2020

Florian Werner spoke about use-cases, equitable models for value exchange, and who to trust in facilitating the ecosystem and bringing stakeholders together.

Sari Stenfors takes us on a guided journey:

using Futures Thinking to envision how different business strategies, policies and actions implemented in the personal data ecosystem can pave the path towards the Desirable Future.

MyData Online Demo "Keep a Lifelog with Personium"

  • Before: Your personal data stored separately in the silos of various domain services…

  • After: Keep in one place and share easily. Then utilized by other apps and selectively disclosed to 3rd parties

Ada Lovelace Institute (ALI) Shares Highlights and References

discussing different approaches to data stewardship and potential principles individuals and organisations can follow

Crossing the Chasm for Privacy respecting Identity, MyData 2020

This is the most highly produced zoom presentation Infominer has ever seen:
Presenters: Nat Sakimura, Sheila Warren. Host: Kristina Yasuda.

1. Accountable Digital Being
2. Expressive Digital Being
3. Fair Handling of personal data
4. Right NOT to be forgotten
5. Human Friendly
6. Open, Interoperable, Leveraging Existing Infrastructure, and Tested
7. Everyone Benefits

Hopefully next week we’ll have found more of these excellent presentation materials

LEIs to enable corporate digital ID with verifiable credentials

The Global Legal Entity Identifier Foundation (GLEIF) is the umbrella body that delegates responsibility for issuing LEIs to local organizations.

It’s such a pressing issue that it was raised by the OECD and B20 (G20 business) just three months ago when they suggested a Global Value Chain (GVC) Passport.

5 Promising Use Cases for Verifiable Credentials - Hackernoon

verifiable credentials promise to appear in our daily lives in the not-too-distant future.

In fact, several industries are already digging in. Here are some of the most visible and promising use cases.

EPS for SSI (Self-Sovereign Identity)

you might be interested to hear that the core of EPS is designed to convert images to high-entropy codes, which work as very long passwords and also as the seeds of symmetric or asymmetric cryptographic keys.

@lissi_id and the three-sided credentials market

When a user holds his:her own credentials locally on the phone, it creates a three-sided market, which puts the holder of the credential in the position of a carrier between issuer and verifiers.

Identity Credential and Personal Data Ownership Perspectives

Research Report from OIX

Many global organisations are using their citizens’ identity and their other personally identifiable information (PII) to help combat the global Covid-19 crisis  […] reignited the debate around protecting public safety vs protecting privacy:  how to combat the contagious threat whilst preserving citizens’ digital identity, security and anonymity?

From CCG Mailing List

Epic VCs vs oCaps/ zCaps discussion

Begins with a post by Kaliya sharing a conversation including Manu and Sam Smith:

Below is the prior threads cut and paste. If you would rather read it in a document form that is attached

Christopher Lemmer Webber followed up with an illustration using the analogy of hygiene to express separation of concerns between oCap and ZCap.

  • Hygiene for a computing pandemic: separation of VCs and ocaps/zcaps

    • You *could* implement zcap-ld on top of VCs…

    • However, you're actually squishing together what should be a separation of concerns in a way that will become *unhygienic*.  Like a lack of proper biological hygiene, the result is sickness in our computing systems. 

    • The observation of "these things seem so similar though!" is true, but you can already make that claim even if you're just looking at the linked data proofs layer.  VCs and zcap-ld diverge from there for two very separate purposes: what is said, and what is done.

The Conversation split off a few times from there, you can browse threads here.

TL; DR: My current view is that the main confusion here may be over the difference between VCs and LD Proofs, not VCs and ZCAPs. VCs are not a generalized container for attaching a cryptographic proof to a document. That's what LD proofs (or JOSE style proofs) are for. VCs *use* LD proofs (or JOSE style proofs) to attach an assertion proof to a document that specifically models statements made by an issuer about some subject, which is therefore inherently about the identity of that subject.


Distributed ID learning path

Christina Yasuda shares a learning path, based on her work navigating the VC-Spec Map by Michael Ruminer, that we shared a few weeks ago and has now been donated to the DIF.

Her distributed ID learning path first describes pre-requisite knowledge, including JSON, JSON-LD, JWT, JWS, JWK, JWA, and sometimes CBOR. She then goes on to break down knowledge areas beginning with the basics: DID-Core, DID-Resolution, DID-Spec, DID Use-Cases. Next, she covers Verifiable Credentials with VC-Data Model, VC Use-Cases, and VC-Implementors Guide, and also Transport, Credential Presentation, and Other Data Formats.

The Models: Space Time • Presentation • Attribute • Relationship • Capability

Relationships in the Self-Sovereign Internet of Things

This post looks at Alice and her digital relationship with her F-150 truck. She and the truck have relationships and interactions with the people and institutions she engages as she co-owns, lends and sells it.

The Dataweb: An Introduction to XDI

When I (Infominer) published the The Augmented Social Network on, a few weeks ago, @SelfSovID said:

One of the two most influential papers I've ever read.
The other was the 2004 vision for the XDI Dataweb by @drummondreed.

So I asked Drummond if it would be ok for me to also publish this paper, which I wasn’t already familiar with. So now you can read it there with on-page navigation

  • The Dataweb: An Introduction to XDI - “presents several examples of classic cross-domain data sharing problems, explains how the Dataweb model can provide a generalized solution”

DIACC marks year end with a slideshow detailing their accomplishments

A few highlights from the report:

  • Digital Identity Laboratory - first lab of its kind for digital ID testing and certification

  • launched the COVID-19 Actions Directory highlighting member initiatives.

  • DIACC has joined the collaborative led by Standards Council of Canada

DIACC is also inviting input on the future of Levels of Assurance

Making sure we have a common way to evaluate and measure the integrity of that data is central to a common bar of acceptance
