Topics & Advance Readings

In advance of the design workshop, all participants produced a one-or-two page topic paper to be shared with the other attendees on either:

• A specific problem that they wanted to solve with a web-of-trust solution, and why current solutions (PGP or CA-based PKI) can't address the problem?
• A specific solution related to the web-of-trust that you'd like others to use or contribute to?

NOTE: To add a paper, create a pull request to this repo with your contribution (preferably .md file or PDF), along with updates to the README.md here and in the Topics and Advanced Readings folder with a link to your paper and your name. Please also include a byline with contact information in the paper itself.

Here are the advanced readings to date:

Sybil Resistance

• Attention as a Source of Scarcity for Decentralized Identity Systems
  • by Maciej Laskus
  • This paper proposes a new approach to introducing scarcity into identity systems without sacrificing privacy and self-sovereignty. The method relies on quantifying attention flows between identities. It is predicated on the fact that attention is a basic element of all cognitive processes. It is also limited and therefore is a natural source of scarcity.

  • by Mitzi László
  • "The question of personal data falls into an unknown territory in between corporate ownership, intellectual property, and slavery."
• On Interpersonal Data
  • by Philip Sheldrake

Rights Frameworks

• Legal Frameworks for Humanity in the Digital Age
  • by Elizabeth M. Renieris
  • "We are allowing the tides of technology and commerce to haphazardly turn everything into commodifiable data. But will we allow ourselves to be reduced to data points and, worse yet, commodified? If we are not deliberate about designing the correct legal frameworks for humanity in the data-driven age, we risk losing sight of our fundamental rights as humans."

Misc.

• Credentials and Correlation

  • by Jack Poole
  • How can users be educated of the privacy implications of sharing multiple attributes about one’s identity, and what role can software agents have?

• Data Value Realisation: Control, Commons & Ownership

  • by Katryna Dow
  • "Since data is becoming a key measure of whether a company will remain relevant through the digital revolution (Opher et. al., 2016), new approaches and business models are required to meet the needs of the changing marketplace (Opher et. al., 2016). To address these increasing data value issues, a number of data-value models and frameworks are emerging, including: Data as Labor; Data as Property; Data Commons; and Open Data. This paper explores the aforementioned frameworks in the context of the emerging human-centred data economy."

• Decentralized Trust for Software Components

  • by Sean Gilligan
  • "A computing device cannot be secure if an attacker is able to surreptitiously insert malicious code on it. Current solutions for signing and verifying computer software — both source code and binaries — generally rely on the same flawed, hierarchical systems as our network connections do."

• GDPR and the right to erasure

  • by Oleg Burundukov and Eduardo Moraes de Morais
  • In accordance to GDPR law, an owner of data has the right to withdraw the initial consent and to request to erase the data. To execute this the owner has to hold an evidence of the interaction. The owner of digital data needs to obtain the digital proof of what and with whom the data have been disclosed.

  • #VC

• PSDAD - Data Format with Secure Semantics

  • by Sandro Hawke
  • "Existing data serialization formats like JSON, JSON-LD, XML, and even ASN.1 (with its various encoding rules) work well enough for conventional computing environments, but they fall short when high levels of both trust and decentralization are required. PSDAD (plaintext self-describing assertional data) is a proposed new approach which uses natural language strings simultaneously as identifiers, delimiters, and documentation, resulting in a surprisingly simple and robust system with distinct advantages over known approaches in certain environments."
  • #data
  • Specification

• Rethinking Priorities: Should Identity Systems Divide or Unite People?

  • by Bryan Ford
  • "The problem of identity has become a hot topic, with the idea of self-sovereign identity in particular attracting significant excitement. The essence of the idea, in short, is to put users in charge of how their identities and personal data are used. Self-sovereign identity posits that users should decide how much and what aspects of their identities to disclose in any situation, and should know and have control over what that information is used for."

• The Universal Ledger Agent: a Logical Result of Rabobank's Journey in Blockchain-based self-sovereign identity

  • by David Lamers
  • "The universal ledger agent (ULA) is a component that is implemented by the app and the verifier. The ULA makes it possible to retrieve credentials from issuers, independently which standards and blockchain they use. Also, a verifier can accept and verify credentials from multiple standards."

Social Key Recovery

• A New Approach to Social Key Recovery

  • by Christopher Allen and Mark Friedenbach
  • "The goal of social key recovery is for the user to specify groups of individuals that together possess the ability to recover the root secret of a wallet."
  • #shamirsecretsharing #sss #keymanagement #masterseed #keyrecovery

• Security Considerations of Shamir's Secret Sharing

  • by Peg
  • "Issues with private key management often pose barriers to the adoption of empowering decentralised technologies and this is exactly what this project aims to address. ... Threshold-based secret sharing schemes provide a powerful tool to address the private-key custody problem. There are promising solutions to the issues explored in this article. However, we have focussed here mainly on technical limitations of such schemes."
  • #reputation #shamirsecretsharing #keymanagement

• Implementing of threshold schemes

  • by Daan Sprenkels
  • "Shamir secret sharing is a method to split secrets into shares, and to later recombine them. However, it does not feature integrity protection of the secret. This article elaborates on Feldman VSS and Pederson VSS, which do protect the message integrity. Furthermore, we show how hashing the shares also protects the message integrity, but is vulnerable to a cheating dealer.
  • #shamirsecretsharing #keymanagement

• Social Key Recovery Design and Implementation

  • by Hank Chiu, Hankuan Yu, Justin Lin & Jon Tsai
  • "Social Key Recovery aims to provide an alternative and interesting way to help user backup their cryptocurrency mnemonic phrase.

UX and Use Cases

• Bringing the Dependencies of a BTCR Wallet to the Swift Ecosystem

  • by Wolf McNally for Blockchain Commons
  • "While all the code to implement something as complex as a DID resolver or registrar could be written entirely in Swift, it makes sense to leverage code already written in other languages, and use Swift as a top-level language used to tie heterogenous modules into a unified application, whether it be a mobile application or server. This document surveys programing languages and technologies of interest, discusses issues of interoperating with Swift, and lists software packages of note."
  • #Swift #UX #iOS #DID

• Digital Identity for the Homeless

  • by Mike Varley and Matthew Wong
  • "The focus of this topic is how to apply existing decentralized digital ID solution to help individuals experiencing homelessness in the city (Toronto). E.g. how to reserve services such as overnight shelters with digital ID, keep track of certificate offered by free public organized re-training programs, and built credibility via repeat use the the same digital ID with varies services run by non-profit organizations in the city etc."
  • #reputation

• Designing an Educational Credentialing Ecosystem

  • by Kim Hamilton Duffy, J. Philipp Schmidt, and Joe Andrieu
  • "One goal of this exercise was to understand whether (1) certain emerging SSI standards -- including Verifiable Credentials (VCs), Decentralized Identifiers (DIDs) -- and (2) blockchain anchoring are essential to the simplified digital verifiable credentialing system. If so, we wanted to trace them to specific requirements. An additional goal was defining a threat model, to understand which aspects could be handled by the system, and which must be addressed by other systems. ... Our concern is that an effective digital credentialing ecosystem would make fraud within an issuing organization more appealing, so our final goal of this paper is to raise awareness among the broader SSI community."

• Assist underrepresented groups when entering the labour market through self sovereign identity

  • by Karolin Siebert
  • "As a consequence of increasing migration we have workers educated by a wild mix of educational systems, this should not be limiting them from approaching and receiving positions that they actually would like to work in and would be suitable for. Official diplomas and certificates, proving previous studies and work experience, are not necessarily recognised, available in physical form or easily translatable in a certified manner. In addition to that and estimate of the World Bank states that 1 Billion of people are without a formal identity. Being assigned one would give them better access to the work market since just their physical presence and knowledge is not enough in many cases, but rather we require proof for education and experience."
  • #DID #VC

• Where's the UX?

  • by Alberto Elias
  • "I've been doing some user testing with both developers and non-technical folks and every single one of them has complained about the authentication and registration flows. We all agree that this work is for nothing if people don't end up using them. This community is definitely human-focused, but initial DID implementations haven't nailed the user experience yet."

• Generating Actionable Intelligence with Wallets and Agents for People & Places

  • by Venn Agency - Sam Chase, Joni McKervey
  • "The purpose of this paper is to discuss building in the principals of sovereign identity systems for places as well as people to better manage multiple stakeholders and layers of access, while preserving both the saliency of digital information and the individual privacy and protections of the physical world."
  • #DID #IoT

• Journalistic use-cases for SSI: signatures, verified claims, and canonical-text registries

  • by Juan Caballero and Jefferson Sofarelli
  • "Our long-term proposal is to design an SSI-platform-agnostic DID widget or middle-ware system for CMSs such that at the time of committing a canonical version of a published piece on a given publication's CMS, that canonical version could be hashed and signed, with signature and hash being stored in an immutable, external record against which the signature could later be checked (i.e., making a verifiable claim of authorship linking the article's original published form to a DID controlled by its author)."

• Designing Trust in Identity Systems

  • By Bentley Farrington & Bart Suichies
  • Putting the ID holder at the center of an identity system comes with great opportunity, but also introduces new risks and barriers to adoption. Many of these are non-technical and such, should be explored in multi-disciplanary way. We propose a human centered design approach to tackle some of these issues and help shift the focus to not just the technical feasibility, but also inclusive usability. This is a prerequisite to creating an identity system which combines technical and human trust elements.

• Applying POLA to User Interaction

  • By Bill Tulloh
  • Object capabilities (ocaps) are increasingly recognized as an important tool for achieving the goals of self-sovereign identity. Many of the principles of self-sovereign identity, such as minimization and protection, can best be achieved through the disciplined pursuit of the principle of least authority that ocaps enable. This paper examines how POLA can be extended to better protect users when exercising their self-sovereign identity.

• #SSI20XX - Model Use-Case Definitions and Implementation

  • by Martin Riedel
  • "This paper proposes that a vision statement (for example #SSI20XX) containing a very limited set of highly specified use-cases and UX descriptions will allow solution providers to commit to a common implementation goal which can greatly benefit solution interoperability and provide valuable feedback to existing specifications in the field of SSI."

Verifiable Claims (VC)

• EU Digital Signature vs. VC Model

  • by L. Boldrin
  • To some extent a pdf signed document (or xml, json...) can be used to make trustworthy information about me available to a verifier. People ask: Why do we need VCs? What is the additional value they bring? This note provides an initial hyoothesis which I would like you to challenge: VCs without ledger provide, as added value, subject confirmation and anonymity/pseudonimity support. VCs with ledger provide, as a further value, just VC revocation."
  • #digitalsignature

• Exploring adoptation of VC sharing to provide value today

  • by Snorre Lothar von Gohren Edwin
  • "With Verifiable Credentials it is important to ask the question what are we expecting the issuer, the holder, and / or the verifier to do? While still making it simple enough for all the users and keeping the needed level of trustworthiness. Sharing is what provides the end value for both the verifying and the sharing party. If there is no sharing, the issuance of the VC has gone to waste. Hence if we are to provide value for the sharing party today, we have to ask the questions of where is this adopted, how can we make this adoption effortless? Can we put most of the work on the service providers? Is the user or another service expected to install software? If so, install software where? Is that software domain-specific or integrated with some existing software?"

• How Do We Bootstrap the Web of Trust for VC

  • by Matt Stone and Dan Burnett
  • "In the world of Verifiable Credentials, it is essential that Verifiers can trust Issuers. To this end, there must be a common understanding of the 'functional identity' of the Issuer. How do humans establish the appropriate level understanding to trust the artifact with conviction? i.e. how does one link 'this key' to 'that real world entity (person, company, etc)'"
