Abstract

The Early Childhood collaboration System (ECCS) is a distributed health data system which provides coordinated, de-identified healthcare information to various types of data consumers. To satisfy this requirement, the ECCS needs a matcher that utilizes Personal Identifying Information (PII) to coordinate information from a wide range of data sources. Due to the sensitivity of PII, the ECCS also needs to guarantee that only matcher can access PII. This report describes a reusable subsystem, called Medical Records Secure Messaging (MRSecureMessaging), which utilizes a reliable cryptographic algorithm to encrypt PII and other confidential data so that matcher and data consumers cannot access each other’s data. It also contains a customized authentication protocol that allows data sources to verify the intended recipient.
