eLearning Forum Asia 2022 Exemplary Teaching and Learning Silver Award

Dr Pauli Lai won the eLearning Forum Asia 2022 Exemplary Teaching and Learning Silver Award for recognizing her initiative on the development of online coding platform! Established in 2019, the eLearning Forum Asia Awards abide to the mission of eLearning Forum Asia to promote the nexus between education and technology, through facilitating the exchange of challenges and successes experienced by different institutions. Dr Lai and her project team members, Mr Ivan Lau and Mr Richard Pang, developed an online coding platform, Codatus, which allows students to use a browser to work on the coding exercises. Codatus allows teachers to customize the question sets and answers for auto-grading. The platform also features an issue tracking function to let students tie their enquiries to the relevant questions and previous attempt records. It also provides a collaborative code-writing feature to pair up students for collaborative editing. This winning project is innovative in reinventing the process of practical coding classes supported by Codatus's unique features. Students also find the platform useful and convenient to facilitate their learning.

Second Prize Award of Huawei ICT Competition Hong Kong SAR 2022-2023

Supervised by Dr Lawrence Cheung, a team of PolyU students, including Au-Yeung Chak Him (EIE student), Bi Jingyun (EIE student) and Li Jingyu (AMA student), won the Second Prize Award of the Huawei ICT Competition Hong Kong SAR 2022-2023 in December 2022. The Huawei ICT Competition is a competitive ICT talent exchange event developed by the Huawei Technologies Co. Ltd. for global college students with the Office of the Government Chief Information Officer of the HKSAR Government as the advisor. The competition attracted more than 600 participants this year. It aims to promote the healthy development of the ICT talent ecosystem and support the integration of industry and education. The content of the competition includes cloud track and IT technologies such as big data, storage and AI. It provides an excellent platform to enrich the ICT knowledge of university students, and nurture innovation and technology talent to sustain the long-term development of Hong Kong.

Champion of PwC HackaDay CTF Competition

Supervised by Dr Haibo Hu, the PolyU Capture The Flag (CTF) Team comprised of Sham Wing Chung (COMP student), Leung Hon Lam (BSc in INS student), Ho Ka Yui (BSc in INS student) and Kwan Chun Kit (BSc in IMT student), won the Champion of the PwC HackaDay CTF Competition on 24 November 2022. HackaDay is the PwC Hong Kong’s annual flagship event which holds competitions for undergraduate students from Hong Kong and Macau to understand more about cybersecurity and cloud ecosystems. It aims to raise students’ competency level and prepare them for a meaningful career in cybersecurity with the CTF Competition. The contestants were required to expose themselves to real-life scenarios during this competition. The contest provided a centralized platform for future cybersecurity talents to learn, hack and co-secure the environment and society.

Third Prize of the Best Student Presentation Award in International Conference on Optical and Photonic Engineering 2022

Our PhD student, Miss Zilan Pan, obtained the Third Prize of the Best Student Presentation Award in the International Conference on Optical and Photonic Engineering (icOpen) 2022 for the paper “Optical Transmission through Thick Biological Tissue using Optical Modulation”. Accurate data transmission is important in biological applications and biomedical devices. Realizing high-fidelity optical wireless transmission with a large penetration depth is desirable. Here, a sequence of amplitude-only patterns at the transmitter is considered as information carrier to encode the transmitted data. The total light intensity at the receiving end is collected and recorded by a bucket detector. Miss Pan’s research work verifies feasibility and effectiveness of the proposed approach with different thicknesses of a biological sample. The experimental results demonstrate the proposed method based on zero-frequency modulation using low light intensity.

Best Paper Award in the 16th International Conference on Provable and Practical Security 2022

Dr Wenjuan Li and her research collaborators from the Technical University of Denmark won the Best Paper Award in the 16th International Conference on Provable and Practical Security (ProvSec) 2022 for their paper "FolketID: A Decentralized Blockchain-based NemID Alternative against DDoS Attacks". ProvSec is an international conference on provable security in cryptography and practical security for information systems. Electronic Identity (eID) is a solution toward solving the identity problem when deploying e-Government. Such solution should not only be secure, but also have to be robust enough under adversarial conditions. In practice, eID often suffers from some security threats such as Distributed Denial of Service (DDoS) attack. NemID is a digital eID used to log into public websites in Denmark. Dr Li's research team developed FolketID, a blockchain-based NemID alternative against DDoS attacks. The DDoS mitigation is achieved by not only utilizing its powerful data distribution ability, but also exploiting the economy system in blockchain. It particularly takes use of the transaction fees to effectively prevent DDoS attacks. The results demonstrate the viability and effectiveness of FolketID in defeating DDoS attacks.
