摘要

Effective contact tracing plays a vital role in controlling infectious diseases but becomes particularly challenging in highly mobile sectors such as tourism. This study presents the Blockchain-Enabled Accurate Contact Tracing Model (BEACTM), a secure and privacy-focused framework that harnesses blockchain’s decentralized and immutable structure to enable precise data collection, verified information exchange, and automated alerts through smart contracts. User privacy is protected through cryptographic key management, digital identity mechanisms, and access control policies, ensuring that sensitive health information remains accessible only to authorized parties. Designed for interoperability with health and travel infrastructures, BEACTM supports cross-border implementation. Simulation results demonstrate significant improvements in accuracy, responsiveness, and trustworthiness over conventional systems, enabling safer and more resilient travel during pandemics. Beyond tourism, BEACTM is applicable to hospitals, public trans- port, and mass events, with future extensions integrating IoT and scalable blockchain architectures for broader public health protection.”
