Patients and donors are the owners of their health data, professionals who attend them are the creators and verifiers of the data (medical staff, pharmacy staff, etc.), and the Information Systems (IS) in the different organizations are the guarantors of the data and have the custody of the information.
HL7 v2 messages have been used for three decades to transmit clinical data between systems, but HL7 FHIR has been approved by G7 and other countries as the standard for data exchange between Information Systems (IS) and patients. SMART-On-FHIR uses OpenID Connect (OIDC) for the authorization and identification of end users (doctors and patients) in the Information Systems. Public Key Infrastructure (PKI) is used to create digital certificates and verifiable data such as health certificates (EU-DGC) and SMART Health Cards (SHC), but quantum computing could break current cryptographic algorithms in the next few months, as announced by different institutions.
A resilient healthcare system requires messages to be exchanged not only over TCP/IP (e.g.: internet) but also over other protocols such as Bluetooth, to enable clinicians to receive and send data to patients even if the connection with the Information System (IS) is down. Decentralized Identity Documents (DID Documents) allow the exchange of public cryptographic material to establish secure connections over the Decentralized Identity Communication protocol (DIDComm) which is independent to the transport layer (TCP/IP, Bluetooth, etc.).
Web 3.0 is the web that the user owns. Secure Web 3.0 Starts with Decentralized Identifiers (DID) as the standard to create a shared, flexible, and resilient identity layer.
Providing a universal, digital and verifiable identity for each individual in the healthcare ecosystem is a key element, not only for professionals but for donors, patients and related persons such as family members, legal guardians and caregivers. The Unified Identification Protocol for Training and Health defines Universal Health Identifiers for the different actors in the healthcare ecosystem for cross-border healthcare.
Imagine a child living in a European country such as Spain gets sick on a trip to Canada. Thanks to the Universal Health Identifier, a local doctor, nurse or paramedic will be able to see the relevant medical history in both English, French and Spanish (among others) in a public or private clinic or hospital, with or without internet connection since Bluetooth can be use (it is protocol agnostic), and be aware of any allergies, existing medication or other important factors. This way the health professionals will be able to carry out the best possible treatment.
ConnectHealth develops secure data communications with resistance to post-quantum computing (PQC) in a network infrastructure of federated organizations managed by the UNID Foundation, in order to improve the security and resilience of the healthcare ecosystem to provide cross-border healthcare to people.
