I am currently an M.E. student at the School of Computer Science, Sun Yat-sen University, under the guidance of Professor Wei Lu. I received my B.E. in Software Engineering from Xi’an Jiaotong University in June 2025.
My research interests include AI security and Model watermarking.
I aspire to contribute to the fields of AI security and Model intellectual property protection, enabling artificial intelligence to develop faster and benefit more people.
Looking for Research Internship opportunities to gain my first industry experience and further enhance my skills.
Thank you for watching.

GeoMark protects embedding-as-a-service models through geometry-aware, localized watermarking: adaptive neighborhoods determine where the watermark is activated, while a natural in-manifold target and geometry-separated anchors provide reliable ownership attribution. Experiments on four benchmarks show strong utility preservation and robust verification against paraphrasing, dimensional perturbation, and CSE attacks, with a low false-positive risk.

FASA bridges low-level forensic traces and high-level semantic understanding for image manipulation localization. It combines adaptive dual-band DCT frequency cues with CLIP-based manipulation-aware semantic priors, then integrates them through a semantic-frequency adapter and a prototype-guided, frequency-gated decoder. Experiments show state-of-the-art localization, strong cross-generator and cross-dataset generalization, and robustness to common image degradations.
