Universal Declaration of Digital Rights Johannes Ernst
all states should recognise and promote universal respect for and observance of both fundamental human and digital rights in physical domain and the digital spaces environment and ensure that these rights are upheld as core elements of a free, open and representative society

In today’s episode, we talk about his new book “Currency Cold War” and relationship, and lack thereof, between digital currency and identity.

On the Trust and Trust Modelling for the Future Fully-Connected Digital World: A Comprehensive Study
Under our analysis of trust and the digital world, we define differenttypes of trust relationships and find out the factors that are needed to ensure a fully representative model.Next, to meet the challenges of digital trust modelling, comprehensive trust model evaluation criteria areproposed, and potential securities and privacy issues of trust modelling are analyzed. Finally, we provide awide-ranging analysis of different methodologies, mathematical theories, and how they can be applied totrust modelling
- Self-Sovereignty for Refugees? The Contested Horizons of Digital Identity
I identify a series of competing logics in the debates around SSI’s emancipatory potential, which relate to four issues: (i) the neutrality of the technology, (ii) the capacities of refugees, (iii) global governance and the nation state, and (iv) new economic models for digital identity. SSI is simultaneously the potential enabler of new modes of empowerment, autonomy and data security for refugees and a means of maintaining and extending bureaucratic and commercial power. I situate SSI in a genealogy of systems of identity control and argue that, in practice, it is likely to feed into the powers of corporations and states over refugee populations.
- Beware of Digital ID attacks: your face can be spoofed! ENISA
Digital identification is the focus of two new reports by the European Union Agency for Cybersecurity (ENISA): an analysis of self-sovereign identity (SSI) and a study of major face presentation attacks.
This report explores the potential of self-sovereign identity (SSI) technologies to ensure secure electronic identification and authentication to access cross-border online services offered by Member States under the eIDAS Regulation. It critically assesses the current literature and reports on the current technological landscape of SSI and existing eID solutions, as well as the standards, communities, and pilot projects that are presently developing in support of these solutions.
- Self-Sovereign Identity as a Service: Architecture in Practice Yepeng Ding, Hiroyuki Sato, University of Tokyo
We propose a practical architecture by elaborating the service concept, SSI, and DLT to implement SSIaaS platforms and SSI services. Besides, we present an architecture for constructing and customizing SSI services with a set of architectural patterns and provide corresponding evaluations. Furthermore, we demonstrate the feasibility of our proposed architecture in practice with Selfid, an SSIaaS platform based on our proposed architecture.

Disposable Yet Official Identities
- Disposable Yet Official Identities (DYOI) for Privacy-Preserving System Design - The case of COVID-19 digital document verification and credential-based access control in ad hoc outdoor and indoor settings (and beyond)
In this paper we report on the design of a service system to endow next-generation COVID-19 mobile applications with the capacity: a) to instantly manage and verify a wide range of possible COVID-19 digital documents (circulation attestations, work or travel permits based on approved COVID-19 tests, vaccination certificates, etc.) and, b) to provide credential-based access control, especially in cases where the Verifier is not a web entity but a human agent with a smartphone, or an IoT device -- mainly in ad hoc outdoor and indoor settings. The system has been designed as a response to the specific needs of a health emergency situation, but it may have a broader application in different cased and areas of control (such as airport and train stations checking points and board controls), where the verification process must exclude the possibility of a physical interaction between the controller and the subject of control, by maintaining a “safe distance” between them and while preserving a certain privacy for the subject of control. Our approach levers the potential of Disposable Identities, Self-Sovereign Identities technologies and Verifiable Credentials (VCs) to enable digital document verification and credential-based access control in ad hoc outdoor and indoor settings (and beyond). Towards this, we specifically introduce the concept of “Derivative” (i.e., transcoded/contextual) Verifiable Credentials. A Derivative VC is a derived bond contract guaranteeing the validity and ownership over the underlying contracts (VCs) whose: a) usability is restricted in a very specific context (that of the “local” and time-limited interaction between a Subject and a Service Provider) and, b) linking table points only to a specific “Pairwise DID”.
