Privacy-preserving Information Sharing: Tools and Applications

Modern society is increasingly dependent on massive amounts of electronic information. There are numerous everyday scenarios where sensitive data must be -- sometimes reluctantly or suspiciously -- shared between two or more entities with limited mutual trust. This prompts the need for mechanisms to enable limited (privacy-preserving) sharing of information. We face three main technical challenges: (1) how to enable this type of sharing such that only the required minimum amount of information is disclosed, (2) how to do so efficiently, and (3) how to deploy these techniques on real-world applications. We take on such challenges by adopting novel building blocks and deploying practical systems to both established and emerging applications, including database screening, genetic testing, social networking, and threat mitigation. In the process, we identify and address a number of open problems as well as items for future work.

Emiliano De Cristofaro is a Senior Lecturer (British English for Associate Professor) in the Computer Science Department of the University College London (UCL). Prior to joining UCL, he was a Research Scientist at PARC (a Xerox company). He received a PhD in Networked Systems from the University of California Irvine, advised -- mostly while running on the beach -- by Gene Tsudik. His research interests include privacy technologies, applied cryptography, and web security/privacy measurements. In 2012, he received an Excellency Award from PARC's Computer Science Lab. He co-chaired the Privacy Enhancing Technologies Symposium (PETS) in 2013-2014, and the Workshop on Genome Privacy and Security (GenoPri) in 2015.
