Contribution
This paper introduces GateChain, a novel blockchain application that enhances border control data security and interoperability through a distributed, immutable ledger.
Findings
GateChain improves data integrity and security for border records.
The system provides real-time access control and verification.
Performance and security evaluations demonstrate its effectiveness.
Abstract
Recording entry and exit records for a country, with properties such as confidentiality, integrity, and auditability, is increasingly important due to rising international mobility and security requirements. Traditional border control systems, which rely on centralised databases, are vulnerable to data manipulation and have limited interoperability between institutions. This study presents GateChain, a blockchain-based application that addresses these vulnerabilities. GateChain aims to enhance data integrity, reliability, and transparency by recording entry and exit events on a distributed, immutable, and cryptographically verifiable ledger. The application provides real-time access control and verification for authorised institutions. This paper describes the architecture and security components of GateChain and evaluates its performance and security features.
