Data Integration and Privacy Systems Lab

Building 32,

University Rd

Southampton SO17 1TR

The Data Integration and Privacy Systems (DIPS) Lab is a cutting-edge research group at the University of Southampton, focusing on developing innovative solutions for secure data sharing, privacy-preserving integration, and intelligent policy management systems.

Our interdisciplinary team works on challenging problems at the intersection of data integration, privacy systems, automated negotiation, and trust management. We develop practical tools and theoretical frameworks that enable secure, efficient, and trustworthy data sharing across organizations.

The DIPS lab is part of the Data, Intelligence and Society (DAIS) research group of the School of Electronics and Computer Science. DAIS is working on the intersection of Web, Data, AI and Society.
