Blockchain technology is being used for secure management and verification of passenger identities in aviation. The system enables tamper-proof, decentralized storage of biometric and identity data, leading to faster check-ins and seamless verification processes. The technology is currently in experimental pilot phases, with projects like Smart Path being tested at airports.

Description
Blockchain-based passenger identification enables a completely document-free travel experience: instead of showing passport and boarding pass multiple times, the passenger's identity is anchored once on an SSI blockchain and verified cryptographically at all control points.
The flight travel identification process is inefficient: a passenger typically shows passport, boarding pass, and other documents 4-6 times (check-in, security, customs, gate, immigration). Each check is manual, time-consuming, and prone to fraud. The IATA One ID initiative standardises blockchain-based travel credentials: the passenger creates a digital travel identity (SSI) once with biometric data (face scan); this identity is anchored on the blockchain; all control points receive authorised read access and can verify the identity within seconds. Austria examined the concept in the passenger outcome report of the Federal Ministry of Finance as a potential modernisation of immigration control. Security Insider reported on seamless travel through SSI technologies at airports. Known pilots: Changi Airport (Singapore), Hartsfield-Jackson (Atlanta), Dubai International Airport.
Perspectives
B2B — organisations perspective
Airport operators and airlines can speed up boarding processes by 30-40% through SSI-based passenger identities, reduce fraud risks, and automate regulatory reporting obligations.
B2C — consumers perspective
Passengers experience significantly shorter waiting times at check-in and security checks through automated identity verification. Contactless processing offers more convenience and safety, especially in times of increased hygiene requirements.
Employees perspective
Airport staff are relieved from time-consuming manual document checks and can focus on more valuable customer service tasks. However, staff require training in handling the new digital identity systems and blockchain-based processes.
Benefits
General
- Increased security through tamper-proof identity data and reduction of fraud risks.
- Significant reduction in check-in times and improvement of the overall passenger experience.
- Improved cross-border cooperation between airports and security authorities.
B2B — organisations
- Reduced operating costs through automated processes and less staff for manual checks.
B2C — consumers
- Faster and more convenient travel processing through contactless identity verification.
Employees
- Relief from repetitive control tasks and the opportunity to focus on higher-value customer service activities.
Challenges
General
- High technical complexity in integrating with existing airport and security systems.
- Need for international standards and compliance with various national data protection regulations.
B2B — organisations
- Significant initial investments for the implementation and integration of the blockchain infrastructure.
Employees
- Training requirements for staff in handling new digital identity systems and changed workflows.
Technology foundation
Blockchain technology offers a tamper-proof, decentralised database for passenger identities, where every transaction is immutably recorded. This technology is particularly suitable because it ensures the highest security standards for sensitive biometric data while enabling cross-border identity verification.
Implementation examples
Smart Path pilot project
The project addresses the challenge of increasing passenger numbers alongside heightened security requirements. The aim is to reduce waiting times and improve the passenger experience through automated identity verification.
Experimental implementation of blockchain-based identity management at airports for contactless passenger identification.
The Smart Path project tests the application of blockchain technology for tamper-proof, decentralised storage of biometric and identity data at airports. The system aims to enable cross-border identity verification while ensuring the highest data protection standards through privacy-by-design principles. The pilot phase focuses on integration with existing check-in systems and security controls.
The system resolves issues with cross-border data transfer and reduces the risk of identity fraud. At the same time, data protection requirements are addressed through decentralised storage and privacy-by-design approaches.
