New procedures are being carried out because the world slowly begins to reopen amid the continuing COVID-19 pandemic. Whereas temperature checks and obligatory face masks have grow to be the brand new regular, the world can be witnessing the rise of digital well being apps, or “well being passports.” 

Many of those purposes function an answer to hint people’ whereabouts or to retailer COVID-19 take a look at outcomes, which may then be introduced to officers throughout journey or gatherings to point out proof-of-health. Whereas modern, privateness and regulatory concerns have been expressed with digital options designed to hint contact or retailer person knowledge by way of smartphones.

Blockchain ensures privateness

In an effort to clear up this drawback, IBM Watson Well being — a knowledge, analytics and know-how companion for the well being trade — has launched a privacy-based utility that can allow people to soundly journey or return to bodily places upon displaying COVID-19 take a look at outcomes and temperature scans. Generally known as the “IBM Digital Well being Go,” this platform leverages IBM blockchain know-how to make sure person knowledge stays personal when shared with organizations that require a verified well being go.

Eric Piscini, vice chairman of blockchain for IBM Watson Well being, informed Cointelegraph that the Digital Well being Go platform particularly makes use of blockchain to establish 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 take a look at outcomes can current these to verifiers, equivalent to airways, with out exposing their medical info.”

In accordance with Piscini, three layers are constructed into the Digital Well being Go 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 excited about understanding if people are protected to have interaction with. “Most of those gamers run a node on the IBM blockchain community, which makes use of refined cryptographic strategies in order that knowledge alternate will be verifiable and trusted,” he added.

Piscini additional talked about that medical knowledge isn’t saved on the platform, evaluating the Digital Well being Go to a credit score rating. On this case, the blockchain ledger captures a person’s well being rating, however organizations, or the verifiers, don’t have any visibility into the person’s private knowledge. 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 determine whether or not or to not interact with people based mostly on their very own insurance policies.

Though the Digital Well being Go resolution continues to be being piloted, Piscini famous that plenty of firms have expressed curiosity in leveraging the applying as soon as it turns into publicly out there.

Just like IBM’s Digital Well being Go, distributed ledger know-how platform Hedera Hashgraph has struck an settlement with Protected Well being Techniques, a companion of Mayo Clinic, to construct a digital well being ID system. Generally known as “HealthCheck,” a COVID-19 testing and well being standing resolution constructed on the SAFE digital well being platform.

Ken Mayer, the CEO of Protected Well being Techniques, talked about throughout a latest Hedera Hashgraph webinar that Digital well being IDs are created for people. Delicate knowledge is saved personal, as that is saved and verified on the Hedera Consensus Service. Mayer stated 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 got partnered with the biggest shopping for co-op for U.S. universities which have about 5,000 members. We additionally simply partnered with the biggest worker advantages market who’s beginning to push this out, beginning with employers and faculties. Mainly, the answer is a white-label cell app.”

Privateness considerations stay

Whereas each Digital Well being Go and the HealthCheck app leverage blockchain and distributed ledger know-how to safe and privatize person knowledge, considerations stay. Jonathan Levi, CEO of enterprise blockchain resolution HACERA and co-founder of MiPasa — a blockchain-based platform that standardizes, normalizes and authenticates knowledge units for open-source use — informed Cointelegraph that it’s crucial for customers of those purposes to grasp their total knowledge workflow:

“From any individual taking a screenshot or a scan of their medical outcomes to utilizing a proprietary cell 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.”

Regardless that Digital Well being Go and HealthCheck are regulatory compliant, Levi defined that understanding the info stream is necessary to make sure that a person’s knowledge isn’t compromised. “All of us keep in mind the considerations raised by the U.Okay. NHS contracts that allowed unprecedented switch of well being knowledge on hundreds of thousands of U.Okay. residents to personal tech firms,” he stated.

Through the Hedera Hashgraph webinar, Mayer did point out that HealthCheck has knowledge 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 knowledge is crucial.

Levi additional defined that MiPasa — which was deployed on the IBM blockchain platform to gather and validate COVID-19 knowledge for the World Well being Group — is just like IBM’s Digital Well being Go in that each platforms are consent-based. The primary distinction in response to Levi, although, is that the Digital Well being Go platform data the consent of customers who’re logged into the cell utility after which scans their medical take a look at outcomes to point out proof-of-health.

MiPasa, nonetheless, merely seeks to offer an employer and an worker (or a person and a verifier) with knowledge and analytics instruments, permitting either side to determine the perfect plan of action.
