Document Confidentiality

Milan Petkovic, Ray Krasinski

Structured Documents

/ Security WGs

HL-7 Cambridge Meeting

October, 2010Slide2

The Problem

Lack of persistent end-to-end encryption for CDA documents

Distributed heterogeneous environments with multiple intermediaries

Encryption currently at transport level (e.g. TLS)

Certain transports lack standard solutions (e.g. USB drive)

Open document-level standard for encryption fosters interoperability

Similar document-level encryption already defined for imaging

Need for enabling technology towards addressing

meaningful use (HITECH), privacy legislation…

Continua Health Alliance, national health networks, etc. foreseen as possible adoptersSlide3

Use case

Third party opinion in

tele

-monitoring

DMO transfers encrypted CDA document to hospital in different affinity domain

Hospital GP accesses the documentGP forwards encrypted CDA document to expert specialistExpert specialist accesses document for 2nd opinionExchanging health records using USB drivesDoctor E-mails record summary to patient as encrypted CDA documentPatient detaches document and saves it on his USB drivePatient shares encrypted CDA document with healthcare providersSlide4

Discussion

Document-level-encryption under discussion in IHE for 2010/2011

Document

encryption

Key

managementPotential involvement of HL-7 for CDA document encryptionEncryption at the CDA level (XML Encryption to encrypt body and selected header fields)Advantage: fine-grained protection (selectively protect metadata and content, …) which allows for routing, searching, de-identification, etc.
