Passenger Name Records (so called PNR) collected by airlines and processed by
Passenger Information Units (dedicated police task force), are critical data in
the prevention and successful investigation of terrorism, drug smuggling, human
trafficking and other serious crimes. This work addresses the challenges of
building a blockchain-based, tamper-proof system for PNR data exchange between
different Passenger Information Units. Utilizing Hyperledger Fabric, we propose
a decentralized architecture that ensures data confidentiality, traceability, and
non-repudiation in order to maintain the chain of custody. Our solution includes
a private data collection mechanism and an off-chain storage system to manage
sensitive information securely. The resulting design and implementation are
incorporated into the TENACITy project platform and further integrated with its
other modules to use travel intelligence data in the fight against crime. The
blockchain subsystem facilitates a secure,auditable exchange of PNR data, with
the key benefit being compliance with European Union regulations on the
protection and retention of personal data. This paper contributes to the field by
demonstrating the practical application of blockchain technology in a sensitive
data exchange scenario, offering insights into system design, implementation
challenges, and potential future enhancements.
