New procedures are being carried out because the world slowly begins to reopen amid the continued COVID-19 pandemic. Whereas temperature checks and obligatory face masks have develop into the brand new regular, the world is additionally witnessing the rise of digital health apps, or “health passports.”
Many of those functions function a resolution to hint people’ whereabouts or to retailer COVID-19 check outcomes, which might then be introduced to officers throughout journey or gatherings to point out proof-of-health. Whereas revolutionary, privateness and regulatory issues have been expressed with digital options designed to hint contact or retailer consumer data through smartphones.
Blockchain ensures privateness
To be able to resolve this drawback, IBM Watson Health — a data, analytics and know-how accomplice for the health business — has launched a privacy-based utility that may allow people to soundly journey or return to bodily areas upon exhibiting COVID-19 check outcomes and temperature scans. Referred to as the “IBM Digital Health Move,” this platform leverages IBM blockchain know-how to make sure consumer data stays personal when shared with organizations that require a verified health move.
Eric Piscini, vp of blockchain for IBM Watson Health, instructed Cointelegraph that the Digital Health Move platform particularly makes use of blockchain to ascertain self-sovereign identification, together with verifiable credentials:
“Privateness is extraordinarily necessary right here, which is the explanation we use blockchain to confirm credentials and permit people to regulate their identification with out the intervention of administrative authorities. People with credentials like COVID-19 check outcomes can current these to verifiers, akin to airways, with out exposing their medical data.”
In keeping with Piscini, three layers are constructed into the Digital Health Move platform. The primary layer is made up of the issuers of credentials, which embody testing labs and hospitals. The second layer is the platform itself, which serves because the ruling engine. Lastly, there are verifiers on the platform, like airways, which can be desirous about figuring out if people are protected to interact with. “Most of those gamers run a node on the IBM blockchain community, which makes use of refined cryptographic strategies in order that data change may be verifiable and trusted,” he added.
Piscini additional talked about that medical data isn’t saved on the platform, evaluating the Digital Health Move to a credit score rating. On this case, the blockchain ledger captures a person’s health rating, but organizations, or the verifiers, haven’t any visibility into the consumer’s private data. Verifiers solely see a “inexperienced gentle” as soon as a QR-code is scanned on a smartphone to point out if a person is wholesome. The verifiers then resolve whether or not or to not have interaction with people based mostly on their very own insurance policies.
Though the Digital Health Move resolution is nonetheless being piloted, Piscini famous that a variety of firms have expressed curiosity in leveraging the appliance as soon as it turns into publicly accessible.
Just like IBM’s Digital Health Move, distributed ledger know-how platform Hedera Hashgraph has struck an settlement with Secure Health Programs, a accomplice of Mayo Clinic, to construct a digital health ID system. Referred to as “HealthCheck,” a COVID-19 testing and health standing resolution constructed on the SAFE digital health platform.
Ken Mayer, the CEO of Secure Health Programs, talked about throughout a latest Hedera Hashgraph webinar that Digital health IDs are created for people. Delicate data is saved personal, as this is saved and verified on the Hedera Consensus Service. Mayer mentioned that many enterprises are signed up to make use of the HealthCheck app, together with Delta Airways and a number of other universities:
“We’ve partnered with the most important shopping for co-op for U.S. universities which have about 5,000 members. We additionally simply partnered with the most important worker advantages market who is beginning to push this out, beginning with employers and faculties. Mainly, the answer is a white-label cellular app.”
Privateness issues stay
Whereas each Digital Health Move and the HealthCheck app leverage blockchain and distributed ledger know-how to safe and privatize consumer data, issues stay. Jonathan Levi, CEO of enterprise blockchain resolution HACERA and co-founder of MiPasa — a blockchain-based platform that standardizes, normalizes and authenticates data units for open-source use — instructed Cointelegraph that it’s important for customers of those functions to know their total data workflow:
“From anyone taking a screenshot or a scan of their medical outcomes to utilizing a proprietary cellular utility, it’s necessary for customers to know what’s being saved on a blockchain, who runs the nodes, how customers and nodes work together with the ledger, together with who has entry to the logs.”
Although Digital Health Move and HealthCheck are regulatory compliant, Levi defined that understanding the data movement is necessary to make sure that a person’s data is by no means compromised. “All of us keep in mind the issues raised by the U.Ok. NHS contracts that allowed unprecedented switch of health data on tens of millions of U.Ok. residents to personal tech firms,” he mentioned.
Throughout the Hedera Hashgraph webinar, Mayer did point out that HealthCheck has data integrations and partnerships with Quest, LabCorp and Mayo Clinics Labs, together with a number of different smaller medical labs that automate the method of returning outcomes shortly for customers. Understanding what these labs will ultimately do with that data is important.

Levi additional defined that MiPasa — which was deployed on the IBM blockchain platform to gather and validate COVID-19 data for the World Health Group — is just like IBM’s Digital Health Move in that each platforms are consent-based. The primary distinction in keeping with Levi, although, is that the Digital Health Move platform data the consent of customers who’re logged into the cellular utility after which scans their medical check outcomes to point out proof-of-health.
MiPasa, nonetheless, merely seeks to offer an employer and an worker (or a consumer and a verifier) with data and analytics instruments, permitting either side to resolve the perfect plan of action.
