Please note: This is a Sole Source Notification. DHHS plans to update its methodology for record linkage (matching) and to implement a Master Person Index as part of the DHHS data warehouse. The intent is to enable secure and accurate information sharing between department and partnering data sources to support management decisions. Civica will provide a software solution that 1) can, to a high degree of precision, accuracy, and efficiency, link records within the person domain across a variety of DHHS and partnering data sources, 2) will present the data contained therein to an API, and 3) will support deployment to cloud-based or on-premises servers operated by DHHS (DTS) or SaaS solutions that can demonstrate zero-knowledge cryptographic architecture.
