A Review of Trusted Broker Architectures for Data Sharing

Abstract

Sharing data across organizational boundaries must strike a balance between the competing data quality dimensions of access and security. Without access to data, it can not be used and, consequently, is of no value. At the same time, uncontrolled access to data, especially sensitive personal data, can result in dire legal and ethical consequences. This paper discusses the trade-offs between security and access for three styles of trusted broker architectures in hopes that this will provide guidance for organizations trying to implement data sharing systems.
