Data security & privacy-preserving systems

Xinle Cao曹新乐

Researcher & joint postdoctoral researcher

Ant Group · Zhejiang University

I am a researcher at Ant Group and a joint postdoctoral researcher with Zhejiang University. My research focuses on secure data management, particularly encrypted databases, oblivious data structures, and privacy-preserving query processing.

I received my Ph.D. in Cyberspace Security from Zhejiang University in 2025, advised by Jian Liu, and my B.Sc. in Information and Computing Science from Zhejiang University in 2020. I am also interested in data security and privacy for emerging AI applications.

Recent updates

Our work on certified adversarial detection was accepted to NDSS 2027.

Selected for the 2026 CCF Doctoral Dissertation Incentive Program (Database Technical Committee recommendation).

Grove, our work on oblivious graph processing with delayed duplications, appeared in PVLDB.

Research interests

Encrypted databases

Understanding information leakage and designing secure protocols for expressive queries and database maintenance.

Oblivious data structures

Making access-pattern protection practical through efficient ORAM, oblivious maps, and graph processing.

Data security for AI

Exploring privacy-preserving retrieval and secure data access for AI systems, alongside work on model security.
