Application and Challenges of Blockchain Technology in Cross-Border Data Security: Practices and Prospects

Date: 21–23 August 2026 
Venue: HKCT Jockey Club Undergraduate Campus, Hong Kong

Welcome Message

On behalf of the Organisation Committee, we are pleased to invite you to the 2026 IIDS Conference on Application and Challenges of Blockchain Technology in Cross-Border Data Security: Practices and Prospects (IIDS ACBC) 

Supported by the Inter-Institutional Development Scheme (IIDS), University Grants Committee (UGC), Hong Kong, this conference aims to bridge the gap between academic research and industrial application. As cross-border data flows exceed trillions of dollars globally, ensuring data sovereignty, privacy, and regulatory compliance has become paramount. 

This event will bring together world-renowned experts, researchers, and industry practitioners to explore how blockchain technology can revolutionise data security infrastructure.
