Standards

  • FYI: What makes a standard ‘world class’? Michael Herman (Trusted Digital Web) (Saturday, 14 August)

  •   A world class standard should have well-defined objectives that respond to real needs in a timely manner.

  •   Its technical content should be complete and accurate.

  •   It should be easy to understand (or as easy as the subject matter allows!) and easy to implement.

  •   Its requirements should be expressed clearly and unambiguously.

  •   It should be validated.

  •   It should be well-maintained.

Reference: A Guide To Writing World Class Standards

In the 17 years i worked at W3C, the formal objections were

(1) "we [the objector] wanted to be on record as saying this but go ahead and publish" (the most common);

(2) we [the objector] have a product, or are about to ship a product, and the feature(s) in  this spec would cause problems in the short-term for our product, and that's more important to us than the Web (no-one will ever admit to this but it's not uncommon)

(3) we object to this spec, we prefer another approach, so here's a bunch of fake objections to slow things down because we can't share our actual business strategy

(4) we believe there's a technical problem with this spec, but we didn't notice it over the past four years despite a last call  review (this one is actually rare but does happen)

Just a reminder that these "politics" and "other-ing" isn't some weird by product of the "identity community", or DIF, or CCG, or OpenID... it's endemic in any long-lived community composed of human beings.

It's not something you're ever rid of... it's something you manage over time;

  • Decentralised Identity: What’s at Stake? A Position Paper by the INATBA Identity Working Group

    INATBA has a specific Standards Committee to liaison with relevant standardisation committees and bodies. Some relevant standardisation committee and bodies include:

  • distributed ID learning path Christina Yasuda based on VC-Spec Map by Michael Ruminer 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. CCG Highlights

  • Linked Data Security ( slide deck

The attached slide deck provides a basic overview (with examples) of Linked Data Security as well as the specifications in that orbit. The W3C CCG is  actively developing a number of these specifications.

Green - General data format standards

Yellow - Vocabulary standards (I the mislabeled VC work)

Magenta - Protocol standards (I mislabeled DID Resolution)

Red - Low-level cryptographic primitives

Purple - General crypto packaging/protocol standards

Orange - Application layer standards

  • Verifier Universal Interface by Gataca España S.L.

    This draft version can be found at https://gataca-io.github.io/verifier-apis/ and has been built using ReSpec. This draft version for VUI includes today 6 APIs:

    • Presentation Exchange
    • Consent Management
    • Schema resolution
    • Issuer resolution
    • ID resolution
    • Credential status resolution

  • Trust Frameworks? Standards Matter Tim Bouma

    He points at the NIST documents about it Developing Trust Frameworks to Support Identity Federations published in 2018. He also points at the Canadian government’s definition of standards.

    “a document that provides a set of agreed-upon rules, guidelines or characteristics for activities or their results. Standards establish accepted practices, technical requirements, and terminologies for diverse fields.”  He goes on to highlight a lot of the work being done in Canada and where it all sits relative to being a standard - “In closing, there are lots of trust frameworks being developed today. But to be truly trusted, a trust framework needs to either apply existing standards or become a standard itself.”

  • W3C WebAuthn V2 Now a Standard Mike Jones

    While remaining compatible with the original standard, this second version adds additional features, among them for user verification enhancements, manageability, enterprise features, and an Apple attestation format. (Recommendation) (CTAP also approaching standardization.

  • Federated Identity, InCommon, and Enabling Federated Access to Research Services

    The panel will review the concepts of federated identities, authentication, and the role attributes play in managing access to services. They’ll further describe how the InCommon Federation and eduGAIN enable academic collaboration across local, regional, national, and international scales, discuss technical alternatives for participation in InCommon, and delve a bit into how research communities and research cyberinfrastructures manage federated access to their services.

  • An overview of blockchain technical standards

This October report is the most comprehensive review of global standards around blockchain tech that we’ve seen. Here’s a list of standards bodies included in a chart towards the end:

  • OASIS releases KMIP 2.1

    The Key Management Interoperability Protocol (KMIP) is a single, comprehensive protocol for communication between clients that request any of a wide range of encryption keys and servers that store and manage those keys. By replacing redundant, incompatible key management protocols, KMIP provides better data security while at the same time reducing expenditures on multiple products.

  • OMG ISSUES RFI FOR DISPOSABLE SELF-SOVEREIGN IDENTITY STANDARD

    This RFI aims to gain a better understanding of the self-sovereign identity space. In particular, the Blockchain PSIG is exploring the potential for standards setting in the area of contextually constrained or ‘disposable’ self-sovereign identity arrangements, building on top of existing W3C standards for self-sovereign identity [DID] and verifiable credentials [VC]. The aim of this RFI is to determine whether new standards for this specific aspect of self-sovereign identity are necessary, desirable and timely, and are not already being developed elsewhere. (The RFI)

A public presentation on the Disposable Self-sovereign Identity RFI will be held on February 3, 2021 at 11:00 AM ET.

The Object Management Group® (OMG®) is an international, open membership, not-for-profit technology standards consortium, founded in 1989. OMG standards are driven by vendors, end-users, academic institutions and government agencies. OMG Task Forces develop enterprise integration standards for a wide range of technologies and an even wider range of industries.

Identity not SSI

The W3C WebAuthn and FIDO2 working groups have been busy this year preparing to finish second versions of the W3C Web Authentication (WebAuthn) and FIDO2 Client to Authenticator Protocol (CTAP) specifications

SDTT is a tool from Google which began life as the Rich Snippets Testing Tool back in 2010. Last year Google announced plans to migrate from SDTT to successor tooling, the Rich Results Test, alongside plans to "deprecate the Structured Data Testing Tool". The newer Google tooling is focused on helping publishers who are targeting specific schema.org-powered search features offered by Google, and for these purposes is a huge improvement as it contextualizes many warnings and errors to a specific target application.

DIF

At its core, WACI can be thought of as a handshake using classic, industry-standard JWTs: the “Relying Party” signs a token given to the end-user’s wallet, and the wallet signs over a “challenge” contained within it, proving ownership of a DID.

Strongly-typed Code to Generate Bob’s UDID Document

Schema.org was founded on the idea of making it easier and simpler for the ordinary, everyday sites that make up the web to use machine-readable data, and for that data to enable an ecosystem of applications used by millions of people. While it's hard to predict exactly what the next decade will bring, if we can all keep these founding concerns in mind as we improve, refine and curate our growing collection of schemas, we'll be doing our part to continue improving the web.

talks like “Simplify Your Least-Privilege Journey with Access Analysis” and “Managing and governing workload identities” definitively provide greater insight.

JSON has its place. But I think we're overusing it in places where a good notation would serve us better.

Since February he has also been the informal chair of the Hospitality and Travel Special Interest Group, a subset within the Decentralized Identity Foundation, an organization creating technical specifications and reference implementations for decentralized identity and working with industries for commercial applications of such technologies.

Already used throughout web3, this is an effort to standardize the method with best practices and to make it easier for web2 services to adopt it.

If you are a developer and want to write a DApp [...] you probably are using API-Keys in your front-end. If this is the case, then you should consider the security risk the publication of the API-Key in your front end represents and ask yourself if it would make sense to switch to a user authentication scheme.

We have a new suite of badges to encourage participation, create value for others, and reflect on that experience. Participants will be able to both earn AND award badges, so they’ll have a chance to prove that they’ve understood the theory surrounding CoPs and badges as well as put those theories into practice.

Considering that the group has accomplished these goals, there is currently no more need for dedicated calls. Work on the Universal Resolver work item will continue on Github (under the Universal Resolver and Identifiers &Discovery and on DIF Slack in the Identifiers & Discovery Working Group channel, #wg-id.

Recently, the WAO team took the opportunity to update the badge platforms page on Badge Wiki, a knowledgebase for the Open Badge community. As the ecosystem continues to evolve we’re seeing some early platforms fall by the wayside and new platforms emerge.

EBSI4Austria is a CEF funded project with two main objectives. First, EBSI4Austria aims to set up, operate and maintain the Austrian’s EBSI node. Second, we pilot the diploma use case on the Austrian level supported by two Universities and data providers as well as verifiers.

The main change is the alignment with the W3C Verifiable Credentials specification 3.

Regarding the standard itself metadata and display are entering the default standard. metadata comes in replacement of metadataJson and remains a stringified JSON that will allow consumers to register specific data which are too unique for issuances to be defined in the context.

display brings in a little bit of novelty 2 images or pdfs, in addition to the more classic HTML.

The SDI technology constitutes a very important example of decentralized counter-power to the web giants. The SDI maintains to keep the practicality of a unique identifier while guaranteeing the security of the data and the user's sovereignty over it.

What already exists, more recently: fine-grained permissions 1:

Summary: The hype over NFTs and collectibles is blinding us to their true usefulness as trustworthy persistent data objects. How do they sit in the landscape with verifiable credentials and picos? Listening to this Reality 2.0 podcast about NFTs with Doc Searls, Katherine Druckman, and their guest Greg Bledsoe got me thinking about NFTs.

Open standards should be developed openly because not enough people work to ensure that equity is central to innovation and development. We believe that openness is an attitude, and one which bears fruit over time from which everyone can benefit.

This is the Use Case Implementation Workstream of the COVID Credentials Initiative (CCI). This workstream identifies privacy-preserving verifiable credentials (VCs) that are most useful to the COVID-19 response and provides a forum and platform for those who are implementing COVID VCs to present their projects/solutions.

    As of Friday, we believe v1 of ION is functionally code complete, and the Sidetree Working Group at DIF (@DecentralizedID) should have a v1 spec candidate ready for the underlying protocol by Jan 21st. Public v1 launch of the ION network on Bitcoin mainnet is just weeks away.

  • What's New in Passwordless Standards, 2021 edition! (Microsoft)

    The Web Authentication API (WebAuthn) Level 2 specification is currently a Candidate Recommendation at the W3C. "Level 2" essentially means major version number 2.

The version 2.1 of theClient to Authenticator Protocol (CTAP) specification is a Release Draft at the FIDO Alliance. This means the spec is in a public review period before final publication. We think you might want to hear about what we think is especially fun about WebAuthn L2 and CTAP 2.1.

  • What Is ISO 27001:2013? A Guide for Businesses

    ISO 27001 is also the cornerstone of a growing international consensus about data security best practices. Australia based its federal Digital Security Policy on ISO 27001. Likewise, ISO 27001 can provide guidance on how to meet the standards of other data privacy laws, such as the GDPR, which often direct companies to it as an example of universal best practices. So if you abide by ISO 27001’s recommendations, you’re on the right track for legal compliance, not to mention improved data security.

This session had the objective to gather (and discuss) a set of recurrent questions people experience when trying to build their first mobile agents.

This was the end result of the session:

FAQ

What’s the best place to start creating your own mobile agent?

How do you get updates once you ship your first version?

Do I actually have to support a fork for every mobile agent I create?

Do I need to use a Mediator?

Goal of the Oberon protocol when building an API:

  • Super effective: no separate session token to required for accessing the API; very fast to issue and verify tokens; 128 bytes required per message
  • Privacy preserving
  • No new crypto, uses BLS signature keys and Pointecheval saunders Construction

This past November, the GBBC released The Global Standards Mapping Initiative 2.0, updating the standards published in 2020. The GBBC is a strong proponent of standardization and intends to serve as a baseline for establishing frameworks and standards that will allow for adoption and innovation.

The arrow for “Issue Credentials” is exactly the same as “Send Presentation,” leading us to believe these activities are similar, but how are they similar? We can’t adequately answer these questions by looking at the above picture and the specification doesn’t provide a ton of help either…

Badges as credentials includes approaches that are well understood and largely replace or augment existing certification practices. Badges for recognition, however, include approaches that remain somewhat confusing to many people.

Harrison Tang, CEO of Spokeo, is the new co-chair of the CCG

W3C CCG (World Wide Web Consortium’s Credentials Community Group) aims to explore the creation, storage, presentation, verification, and user control of credentials (i.e. a set of claims made about someone, or a person record).

An alternative to passwords that includes QR Codes is described, and typical use cases are described. This document also provides an overview and context for using QR Codes for security purposes.

every pico is serverless and cloud-native, presenting an API that can be fully customized by developers. Because they're persistent, picos support databaseless programming with intuitive data isolation. As an actor-model programming system, different picos can operate concurrently without the need for locks, making them a natural choice for easily building decentralized systems. W3C Press Release - Decentralized Identifiers (DIDs) v1.0 becomes a W3C Recommendation worth reading to see who contributed comments (and notice who didn’t)

For individuals in particular, DIDs can put them back in control of their personal data and consent, and also enable more respectful bi-directional trust relationships where forgery is prevented, privacy is honored, and usability is enhanced.

Since verification is off-chain (and generally fast/inexpensive, depending on the provider), and since this avoids on-chain storage of potentially correlatable data, this is often the preferred solution.

Driven by our motivation to make SSI more adoptable, we built the world’s first turn-key, open source trust registry solution. This work was sponsored by the European Self-Sovereign Identity Framework Lab, which is an EU consortium that provides funding for projects that build SSI open source tools. Any ecosystem provider can use the trust registry implementation to enable governance in their verifiable data ecosystem.

The concept behind a Trust Registry is that a Wallet needs to know which decentralized identifiers (DIDs) to “trust” as a source of truth. At many levels, this “trust” translates to “authority” – knowing that somebody, centralized or decentralized, is responsible for maintaining a list of trusted DIDs.

  • Keys can be given different capabilities using Verification Relationships
  • We support 4 Verification Relationships: Authentication, Assertion, Key Agreement, and Capability Invocation.
  • DIDs can now be controlled by other DIDs
  • DIDs can now have service endpoints
  • Dock now supports off-chain DID Documents

Here’s my premise – we don’t have standards nor interoperability – at least not as people really need. We have been through a process that is powerful and good – but what we have is what I call “premature standardization.” It’s a great start but nowhere near where things will be.

The goal of IATA One ID is to set industry standards that further streamline the passenger journey with digitalization of admissibility and a contactless process through secure biometric enabled identification.

By producing an accessible, open-source wrapper library, Tangle Labs provides any business or development team the opportunity to easily explore SSI and to test and prototype solutions that can bring added value to your business.

The discussion gets very concrete when Daniel describes selective disclosure JWT, or SD-JWT, a new IETF specification he is coauthoring that offers a simple and easy-to-adopt approach to produce JWTs capable of supporting selective disclosure. Here at Identity, Unlocked, we are huge fans of this new specification, and we hope this episode will help you get started!
