Today, more than ever, there is a critical need for organizations to share data within and across the organizations so that analysts and decision makers can analyze and mine the data, and make effective decisions. However, in order for analysts and decision makers to produce accurate analysis and make effective decisions and take actions, data must be trustworthy. Therefore, it is critical that data trustworthiness issues, which also include data quality, provenance and lineage, be investigated for organizational data sharing, situation assessment, multi-sensor data integration and numerous other functions to support decision makers and analysts. The problem of providing trustworthy data to users is an inherently difficult problem that requires articulated solutions combining different methods and techniques. In the talk we will first elaborate on the data trustworthiness challenge and discuss a trust fabric framework to address this challenge. The framework is centered on the need of trustworthiness and risk management for decision makers and analysts and includes four key components: identity management, usage management, provenance management and attack management. We will then present an initial approach for assess the trustworthiness of streaming data and discuss open research directions.
