In our work the Central CodeBook (CCB) functions as an 'honest broker' by mapping between internally meaningful, subject codes (IDs) and sensitive external identifiers like medical record numbers. The CCB is a web service enabled database-backed web application that brokers communications with our evolving EMR via the Clinical Information Network Exchange (CNEX).
