Delegates at the International Civil Aviation Organization (ICAO) TRIP Symposium in Montréal are focusing on how digital identity, biometrics and secure data-sharing systems can be deployed strategically and inclusively while maintaining security, privacy and State control over border decisions.
ICAO Digital Travel Credentials (DTCs), biometric technologies and secure data-sharing systems have advanced significantly, with pilot projects and operational deployments demonstrating their potential to reduce friction during passenger journeys while maintaining high levels of security and privacy.
Digital credentials and biometric verification
ICAO’s vision is for travellers to use secure and interoperable digital travel credentials alongside biometrically enabled verification throughout the travel journey, reducing the need to repeatedly present physical documents while preserving governments’ authority over identity verification and border control decisions.
States participating in the discussions stressed that trust and security depend on strong evidence-of-identity processes, secure document issuance and reliable foundational data.
ICAO Annex 9 standards, Doc 9303 specifications and the Public Key Directory (PKD) form the foundation of the international trust framework supporting secure and interoperable travel document verification.
However, one of the main obstacles to broader seamless air travel implementation is fragmented governance both within individual countries and internationally.
Government ministries, border agencies, airports and information technology teams often operate at different speeds, use different technical terminology and do not always coordinate from the beginning of projects. According to the discussions at the symposium, stronger alignment will need to start domestically before extending internationally.
Risk of a two-speed digital travel system
Participants also highlighted the risk that rapid technological modernisation could widen the gap between advanced countries operating interoperable e-passport systems and States with fewer financial or technical resources.
Vulnerable groups, including refugees and stateless people, can also be excluded from modern travel infrastructure, while small States and countries with limited resources face persistent challenges in joining global systems or implementing sophisticated identity checks because of their cost and technical requirements.
Remote and lower-capacity regions, including Pacific Island nations, also face distinct mobility requirements that need to be considered as digital travel systems expand.
The development of a two-speed system could leave some countries and airports behind. Airlines, airports, governments and technology providers will therefore need to coordinate implementation across regions if seamless air travel systems are to operate internationally.
AI fraud and quantum computing create new security challenges
At the same time, aviation authorities are facing emerging security risks, including AI-enabled document fraud and identity spoofing.
Advances in quantum computing could eventually challenge the cryptographic systems underpinning passports and digital identity platforms. Participants raised concerns over the concept of “harvest now, decrypt later”, under which encrypted information could be collected today and decrypted in the future once sufficiently capable quantum computers become available.
The issue is prompting discussion about the eventual adoption of post-quantum cryptographic standards, even though those standards continue to evolve.
Regulatory and privacy requirements are creating further complexity. In some jurisdictions, for example, regulations prohibit the remote reading of passport chips.
Costs remain central to global adoption
Cost is another central consideration. Systems that significantly increase operational expenses or costs for passengers are unlikely to achieve broad adoption among airports, airlines or travellers.
The issue is particularly important for smaller and remote States, where requirements to introduce complex or overengineered systems could prove financially unsustainable and potentially affect citizens’ access to regular passports.
A phased approach to modernisation is therefore being discussed as a way of providing States and airports with a structured route towards digital travel.
This approach would begin with the digitisation of pre-travel checks, followed by the issuance of secure digital credentials and, subsequently, the linking of identities to biometric verification and seamless passenger corridors.
Interoperability would be incorporated into new systems from the outset to support future cross-border use, while additional security capabilities would be introduced to identify AI-generated document forgeries and protect the integrity of traveller identities.
Some participants also see the transition towards post-quantum cryptography as an opportunity for countries adopting digital systems later to move directly towards technology designed to withstand emerging security threats.
