Exploring the use of digital wallets and attestations to address challenges in the global adoption of eInvoicing. Specifically, this focuses on the value of the W3C DID specification in combination with standards like PEPPOL. The topic will be addressed by a series of FIDES Labs. One upcoming lab will focus on discovering parties and eInvoicing metadata via a FIDES Bluepages catalog.

Demonstrating how eIDAS 2 based digital wallets and attestations can enhance the security, ease of use, and reliability of online shopping. Showing benefits for both webshop owners and their customers

Exploring and demonstrating how digital wallets, attestations, and the W3C DID specification can be used to establish a digital product passport for vehicles or other product categories. This lab will focus on an agreed DPP interoperability profile that bridges initiatives and specifications from UNTP, CIRPASS2, Trace4EU, and others.

Investigating options to combat fake news by combining the global C2PA (Coalition for Content Provenance and Authenticity) standard with the upcoming EU Digital Wallet. This lab addresses the challenge of verifying the authenticity of digital content in the AI age. It explores how EU Digital Wallets can identify the authentic sender of a video or photo and ensure that the content hasn’t been altered.goes here

Using digital wallets to streamline procurement processes, enabling buyers to easily request digital, machine-readable sustainability certificates or other company credentials, and allowing suppliers to provide this information seamlessly across borders and domains.

Implementing the use of wallets and attestations (credentials) for authorisations (mandates) in various business processes, such as procurement and signing on behalf of a company. This lab covers both personal and organizational wallets.

Demonstrating the value of eIDAS2-compliant personal and organizational wallets for data spaces. This relates to several other FIDES Labs topics, such as Mandates, Remote Signing, Trust Registries (e.g., OpenID Federation), and data-sharing strategies.

Demonstrating how personal and organizational wallets can integrate with remote HSM solutions from eIDAS QTSPs using the CSC (Cloud Signature Consortium) standard. Although this is an important topic, there are currently few public examples available.

Developing solutions for user binding (confirming that the wallet is operated by the user) and subject binding (confirming that the user is the subject of the presented attestations) to prevent identity theft and collusion attacks. These solutions will be tested in a common process.

Addressing one of the unresolved challenges related to digital wallets: how to automatically select the preferred mobile wallet in same-device scenarios (e.g., mobile phone). Currently, no mature specification exists for users to configure a default wallet. Google and Apple are working on the “Digital Credentials API,” which could lead to rapid adoption. However, few third-party tests or implementations have been conducted. FIDES will explore this new specification.

Exploring and demonstrating how digital wallets and attestations might be affected by post-quantum technology, and how these challenges can be addressed.

One of the key open topics in the global adoption of digital wallets and attestations is the ability for users to verify whether an attestation was issued by a legitimate issuer in compliance with local laws. Current (static) mechanisms are not scalable. Although agreed-upon and mature specifications exist, various approaches are still being developed, such as OpenID Federation, GAN (Global Assurance Network) using TOIP Trust Registry Protocol, and the EBSI Issuer Trust Model. FIDES Labs can be initiated to develop example solutions that implement one or more of these specifications in specific domains or use cases.
