Areas of Interest

My research interests lie at the crossroad of Privacy, Security, Data Mining and Databases: Security and Privacy issues raised by data integration and distributed Data Mining techniques; Security issues in Databases and Federated Search; Applied Cryptography and Secure Multi-Party Computation techniques; Documentanonymization to prevent the disclosure of sensitive attributes.

Privacy and data utility are often perceived to be at odds. An omniscient data source would have many benefits, particularly in support of data analysis and information retrieval. However, an omniscient data source eases misuse, such as the growing problem of identity theft. What we need is the ability to compute the desired \beneficial outcome" of sharing data for mining or analysis without having to actually share or disclose data. Secure multi-party computation (SMC) has emerged as an answer to this problem. Informally, if a protocol (in a distribute environment) meets the SMC definitions, the participating parties learn merely the final result and whatever can be inferred from the final result and their own inputs.

Based on the concept of SMC, my main research focuses on designing SMC-based computationally eficient protocols and models to facilitate privacy-preserving data analysis and information retrieval tasks.
