Executive Summary

Current data sharing and integration among various organizations require a central and trusted authority to collect data from all data sources and then integrate the collected data. This process tends to complicate the update of data and to compromise data sources' privacy. In this paper, a repository for integrating data from various data sharing services without central authorities is presented. With this repository, data sharing services can update and control the access and limit the usage of their shared data, instead of submitting data to authorities, and, hence, this repository will promote data sharing and integration.
