Privacy-Preserving Data Mining

Data is ubiquitous, but knowledge is scarce. Data mining - finding interesting patterns from data, relies on the collection of massive amounts of data, often from multiple different sites. However, privacy/security issues often restrict access to data. Is it possible to mine data when access to it is restricted? My goal is to develop technology to address this in the distributed case: such that only data owners or their representatives have true access to data, but accurate mining results are still computed. We develop algorithms that share some information to calculate correct results, where we can show that the shared information does not disclose private data.

Other Data Mining and Security Topics

Privacy issues in distributed data mining is only one area where data mining and security interact. Other areas of research include security concerns posed by data mining results (the data isn't private, but what might be learned from it is) and applications of data mining to security (e.g., intrusion detection).

Spatio-Temporal Data Mining

Spatio-Temporal Data Mining raises a whole new set of problems. Spatial data is complex in character, and requires new techniques for doing data mining.

Potential Independent Study Projects

If you would like to pursue a independent study with me, please see the instructions on proposing such study. Occasionally I have specific projects that may be of interest, often involving collaboration with corporate partners. These are listed below:
