The National Science Foundation awarded Professor Yingying Chen with a grant to research "SEMOIS: Secure Mobile Information Sharing System."

This project aims to build a secure mobile information sharing system (SEMOIS) that supports secure and privacy preserving real-time information sharing. SEMOIS has the ability to store secure data items with flexible access control at insecure storage nodes and enables users to send context-based messages with late-binding features. A set of smart learning methods will be developed to extract short-term and long-term geo-social patterns from multimodal sensing data collected by mobile devices for social networking purposes, e.g., geo-social patterns are used to derive hidden communities.

The project plans to equip both graduate and undergraduate students with the necessary background and practical skills for survival in the emerging job market and further contribute to the development of the pervasive computing field. In addition, SEMOIS can be used by middle and high school students from the Tri-State area.
