- Special Session: Integration of Blockchain and Privacy-Enhancing Technologies for Data Security -

With the development of the digital society and digital economy, data has become a core production factor, making the mining of its value an urgent priority. On the other hand, data security remains a key focus in the field of information technology. Therefore, achieving privacy-preserving data fusion computing and value extraction has emerged as a critical research topic. The integration of blockchain and privacy-enhancing algorithms presents a viable approach to this challenge, enabling "usable yet invisible, controllable yet measurable" data governance.However, current blockchain and privacy-enhancing technologies still face challenges in terms of efficiency, security, and application models, hindering their widespread adoption in real-world business scenarios. Next-generation blockchain architectures, high-efficiency privacy-preserving techniques, and their integrated solutions for secure data utilization constitute the focal points of this session.

Organizer: Prof. Zhaozhong Guo, Beijing Information Science and Technology University, China

Guo Zhaozhong holds a dual bachelor's degree in Science and Economics from Peking University, a Ph.D. in Applied Mathematics, and is a Boya Postdoctoral Fellow and Senior Engineer. He has been selected for a provincial-level youth talent program and currently serves as a professor and master's supervisor at Beijing Information Science and Technology University, as well as a specially appointed researcher at the Ministry of Education's Key Laboratory of Blockchain. With extensive expertise in cryptography, blockchain, and privacy computing, he excels in cryptographic security protocols and blockchain architecture design. He has published over 10 SCI/EI-indexed papers and filed more than 20 patent applications, with 12 granted. In cryptography, his identity-based hierarchical encryption mechanism (IBE) won second prize in a military cryptographic algorithm competition. In blockchain, as project leader, he has overseen the military's "Huiyan Action" achievement transformation and application project and an open research project from the Yunnan Provincial Key Laboratory of Blockchain Application Technology. He has also participated as a key researcher in multiple national key R&D projects on blockchain and pre-research projects on blockchain for the Central Military Commission's Equipment Development Department. The consensus mechanism he designed, Baguena, was included in the China Blockchain Blue Book.
