A huge volume of data is collected and stored by various sensors, monitoring systems, and auditing systems. Such data often contains sensitive or private information. How can we enable effective distributed information sharing and decision making in a secure and privacy-preserving manner?

The Seaglass project aims to design and develop novel cryptographic constructions to enable secure, privacy-preserving distributed information sharing. The project has employed techniques based on computation of encrypted data to ensure privacy [1-4] and has also developed secure methods for information aggregation [5,6].
