Outline of Annual Research Achievements |
This year, our research will focus on balancing privacy protection and the application of spatio-temporal data in the post-pandemic era. We will conduct social experiments and leverage mature commercial products to explore practical and feasible solutions. Our efforts include enhancing GNSS security through comprehensive spoofing experiments to protect against potential threats. Additionally, we will improve spatio-temporal information authentication by implementing advanced cryptographic techniques and Trusted Execution Environment (TEE) solutions to ensure data integrity and reliability. I will also committed to developing de-identified localization systems using IoT devices, which will help protect user privacy while providing accurate location data. To support this, we will optimize a lightweight blockchain platform based on Low Power Wide Area (LPWA) networks to enable secure and trusted location data management. Furthermore, we aim to extend these solutions to a wider range of platforms and use cases, addressing the evolving needs of the post-pandemic era and ensuring our technologies remain versatile and effective.
