Executive Summary

The notion of confidence policy is a novel notion that exploits trustworthiness of data items in data management and query processing. In this paper the authors address the problem of enforcing confidence policies in Data Stream Management Systems (DSMSs), which is crucial in supporting users with different access rights, processing confidence-aware continuous queries, and protecting the secure streaming data. For the paper, they first propose a DSMS-based framework of confidence policy management and then present a systematic approach for estimating the trustworthiness of data items. The approach uses the data item provenance as well as their values.
