The need for controlled sharing of sensitive information occurs in many realistic everyday scenarios, ranging from critical (e.g., national security) to mundane (e.g., social networks).

This poses two challenges: (1) how to enable this type of sharing such that parties learn no (or minimal) information beyond what they are entitled to, and (2) how to do so efficiently, in real-world practical terms. In this paper, we discuss the concept of Privacy-preserving Sharing of Sensitive Information (PSSI) and provide an efficient system implementation. The PSSI system functions as a privacy shield that protects parties from disclosing their respective sensitive information. Although seemingly simple, the design and deployment of PSSI prompts a number of new and interesting practical challenges, which we address in this paper....
