# Blockchain-based Passenger Identity Management

> 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.

## Benefits

- Reduced operating costs through automated processes and less staff for manual checks.
- Faster and more convenient travel processing through contactless identity verification.
- 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.
- Relief from repetitive control tasks and the opportunity to focus on higher-value customer service activities.

## Challenges

- Significant initial investments for the implementation and integration of the blockchain infrastructure.
- High technical complexity in integrating with existing airport and security systems.
- Need for international standards and compliance with various national data protection regulations.
- 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.
