On 2 June 2026, Aptitude was presented at the International Telecommunication Union (ITU) workshop on “Global interoperability for trust management of digital identity for humans and agents”, held at ITU Headquarters in Geneva, Switzerland. The workshop brought together a broad international stakeholder community to discuss trust management and interoperability for digital identities used by humans and agents.
Organised by the ITU alongside a meeting of its Study Group 17, which focuses on security, the workshop addressed trust management for digital identities used by humans and AI agents. It aimed to identify key security and governance challenges, support cross-stakeholder consensus on core requirements for trust management standardisation and explore actionable recommendations to advance standardisation work in the field.
During the workshop, Aptitude was presented in the context of exchanges on different trust interoperability models across Europe, America, Asia, Australia and Africa. References were also made to the Aptitude Playground as a testing environment for exploring interoperability and trust management scenarios.
The discussions explored how trusted and resilient digital identity ecosystems can support secure data and credential exchange across borders and across different regulatory and technical environments. A practical example discussed in this context was the future use of an Australian digital driving licence within the European Union, for example for car rental or roadside police control. Similar interoperability scenarios may also apply to other types of digital credentials, such as health cards, passports, vehicle registration certificates and student cards.
The first session, “Models for trust management of credential issuers”, focused on approaches for the discovery and retrieval of issuer certificates that demonstrate conformance to identity rules within a given ecosystem, as well as on the approval of wallets for identity-related use cases. The session included contributions and exchanges with Philippe Nieto, Debora Comparin, Arnaud Taddei, Fred Werner and Anthony Carmoy, highlighting the importance of international cooperation in advancing trust management and digital identity interoperability.
Aptitude’s participation in the ITU workshop reflects the project’s role in supporting secure, interoperable and user-centric digital identity solutions, while contributing to international discussions on trust management and cross-border credential exchange.
