Welcome to Data Security and Privacy Lab (DSP-Lab, founded in 2017) in the Department of Computer Science and Engineering at the University of Notre Dame. Here at DSP-Lab, we aim to explore and resolve security and privacy issues existing in the world of data so that people will be less involved in security or privacy breach in the big data era. The research areas of DSP-Lab at Notre Dame spans widely across multiple areas, from data science research to traditional security research, owing to the interdisciplinary nature of the security and privacy research in the big data.
Current research areas
The following sections describe our current on-going research projects. Please contact Prof. Taeho Jung if you want further discussion.
Secure and accountable management of big data
More and more data are generated and collected nowadays, but we do not have a way to monitor and control the management of those data. We study how to let individuals hold ultimate controls over their own personal data being collected everyday and everywhere.
Keywords: Accountability, data provisioning, secure provenance
Relevant software: Secure fuzzy deduplication on images
Privacy-preserving deep learning
Deep learning technologies have given birth to numerous innovative applications in our life. We believe now it is a proper time to consider the user privacy implications behind this breakthrough technology. In this project, we study how to enable various deep learning technologies without breaching individual privacy.
Keywords: Privacy-preserving computation, applied cryptography, secure multi-party computation, differential privacy
On scalability and maintenance cost of blockchain
Blockchain has various desirable security properties (e.g., tamper-proofness, decentralization), however it has several shortcomings as well. Our goal is to make blockchain more scalable and sustainable.
Keywords: Blockchain, efficiency, scalability
Relevant software: Blockchain with proof of deep learning
We have been actively collaborating with the following groups/labs.
- Computing with Emerging Technologies
- Sustainable Computing Laboratory (SCL)
- Distributed Cooperative Systems Research (DISCOVER) Lab
- IIT DB Group
