Privacy Preserving Information Sharing

Distributed Privacy Preserving Information Sharing

In this paper, we address issues related to sharing information in a distributed system consisting of autonomous entities, each of which holds a private database. Semi-honest behavior has been widely adopted as the model for adversarial threats. However, it substantially underestimates the capability of adversaries in reality. In this paper, we consider a threat space containing more powerful a...

Privacy-preserving Personal Information Management

The spread of Information and Communication Technologies (ICTs) has transformed the way we deliver services, and has made them in general more efficient and more accessible to users. With these improvements however came new challenges. The extensive use of electronic services in our daily life, and the massive gathering of transactional data have led to serious privacy violations. In this thesi...

Privacy-Preserving Distributed Information Sharing

In many important applications, a collection of mutually distrustful parties must share information, without compromising their privacy. Currently, these applications are often performed by using some form of a trusted third party (TTP); this TTP receives all players’ inputs, computes the desired function, and returns the result. However, the level of trust that must be placed in such a TTP is ...
