Resume business trusting that your staff & customers have a clean bill of health

By proving who is healthy or at risk, our technology can help governments, healthcare providers and businesses efficiently reduce the risks of resuming operations.

Why current solutions don't work

Invasion of privacy

Contact-tracing apps meant for mass surveillance compromise individual privacy and confidentiality. There is no transparency on how collected data is being manipulated, posing legal and ethical issues.

Fraud & misguided incentives

“Immunity certificates” that grant work and social freedom for positive-tested individuals can be forged and altered. They may also create incentives for deliberate self-infection.

Lack of standardization

Public health uncertainty and jurisdictional heterogeneity mean that employers are defacto responsible for ensuring employee & customer safety while reopening.

Trust is the only long-term solution

Immunodex helps you trust your employees' health and vice versa
so you can resume business safely.

Verifiable Health Passport (VHP)

The VHP is a set of trusted, tamperproof credentials about an employee's health (issued by a physician) that employers can verify to grant them access to work and interact in physical environments.

Privacy-preserving

Our user-centric design adheres with principles of the EU GDPR. Users hold, own and control their data, exchanging it with other parties only upon consent. With zero-knowledge proof, users don’t have to disclose more than what’s needed.

Secure & fraud-proof

Decentralized identifiers of credential holders and issuers with peer-reviewed cryptographic techniques ensure your employees really are compliant as they claim.

No more paper "doctor's notes"

Ensure that health assessments issued by a physician are unalterable and completely auditable. Data profiles can be tailored to your organization's objectives or requirements.

Rapid implementation

Implement our technology at pandemic speed. Any camera-enabled device can issue and verify VHP credentials, and our technology can be readily whitelabelled.

Coordinate user flow

Streamline the scheduling, reminding and follow-up of health assessment and verification appointments. Availabilities can be adapted to changes in user volume and acuity.

Decentralized network

We use a globally distributed self-sovereign identity network with a blockchain registry to ensure privacy-preserving credentials.

User-friendly design

For you & your staff, the VHP runs as a secure mobile or tablet app with an easy-to-use interface. Information is exchanged by simply scanning QR codes.

How it Works

Issuing or verifying a health credential on Immunodex
is easy

1

First, an employee books a doctor's appointment.

An authorized employee books an appointment for a health assessment or diagnostic testing (as mandated by your organization or law) with a physician on Immunodex. Our app reminds them with location and time prior to the reservation.

2

Next, the physician performs the assessment & issues the credential

After onsite check-in at the healthcare provider's, the employee is assessed by a physician or tested, creating a record in their VHP. The outcomes are sent directly to the VHP, with any "doctor's orders" if needed.

3

The employee's VHP is ready for inspection

With their consent, you can now inspect your employee's VHP, exchanging information via a QR code and authorizing them to proceed with the task at hand.

Use Cases

Back-to-Work
Employers who rely on in-person operations or physical interactions can allow staff recognized to be free from Covid-19 and in good health to return to the workplace. Staff and customers can be reassured that they are in premises posing a low risk of Covid-19 transmission

Holder

Verifier

An employee
An employer (e.g. restaurant, shopping mall, grocery store, warehouse, etc.)
Back-to-School
Schools and daycares can allow students to return. Parents can rest assured knowing that their child is interacting with other certifiably healthy children and school staff. Coverage can be extended to include critical immunizations such as those for measles, pertussis etc

Holder

Verifier

An student, teacher or school employee
A school, nursery, daycare, university, etc
Back-to-Sky
Airlines, trains and transportation industries can resume carrying passengers, especially in proposed “travel bubbles” aimed at reviving the tourism industry. People can be allowed to cross borders upon presentation of a recognized proof-of-health that is tamperproof and verifiable. Likewise, hotels and hospitality sectors can resume serving guests

Holder

Verifier

A tourist, cross-border commuter, traveller
Airport/train security control/check-in desk, border customs
Back-to-Clinic
Physicians and healthcare workers can return to hospitals and clinics, especially for non-emergency yet important services such as ophthalmology, dermatology, dentistry and elective surgeries. Long-term care homes housing a highly vulnerable demographic could better mobilize and prioritize staff based on their health status

Holder

Verifier

A doctor, healthcare worker, clinician, patient or visitor of patient
A hospital, clinic, long-term care home

ID’s and doctor's notes can be faked. With stakes so high, how can anyone be trusted?

Solves this using cryptography & blockchain

It ensures that all transactions are secure and unalterable

  • Self-sovereign, meaning consent-based and privacy-preserving. Specific data can be anonymized via zero-knowledge proof cryptography

  • Option to digitally sign with revocable ring signatures for higher privacy protection

  • Safeguard against theft and fraud with complete traceability in data provenance

  • In adherence with the principles of the EU GDPR Download Whitepaper

Frequently Asked Questions

Does this compromise the privacy and freedom of my workers/customers?

Actually, the opposite. You are directly contributing to everyone's safety and indirectly contributing to your own by using verifiable credentials: you are also increasing your privacy beyond what privacy regulations in most places require. This exceeds what companies are required by law to do today! It is a consent-based system. Your workers/customers have the freedom to share your information to a valid inspector or refuse, on a case-by-case basis.


Immunodex indirectly contributes to your workers/customers' safety by letting policy makers in a company or government know about the health of their people in a timely and reliable manner. In order to do this, the "paper trail" of the health records must be traceable. This trail rightfully belongs to the individual. But right now, it does not. It sits on doctors' computers or the hospital's servers, or the government has it. You have no access to your own health data, but we let you hold your own data. Finally, the inspection is not only consent-based, but requires a minimum exchange of information, which means your workers/customers might not need to reveal ALL data, but simply fulfil the requirements of you the inspector (this is "zero-knowledge proof").

We don't know about the immunology, whether having antibodies actually confers long term immunity to Covid-19. Also, the antibody test market is full of scams!

Yes, you are right. And it doesn't matter. Immunodex is a bias-free, completely neutral historian that records personal health data for that person. Immunodex is starting off with use cases concerning Covid-19 because that is important and urgent. New research and findings do not invalidate records on Immunodex. In fact, reliable records contribute to ongoing research.

What happens if I got a result from a test kit that was later recalled/nullified by the government?

Your record remains with you forever. Immunodex is independent of policies from government or authorities. Inspectors requesting proof-of-health will see not only the result but also that the test kit used is or is not on the [currently] approved list of test kits.

What happens if I lose/break my phone? How do I access the "backup?"

The patient or authorized person (“Holder”) primarily holds the information on their computer or mobile device(s), and the information should be backed up (location is the Holder's choice). A back-up is an encrypted file that is an exact copy of the one on the main device(s). The Holder accesses their information (working copy and backups) via a key. If the key is lost, then the patient undergoes a Key Recovery Process, which is similar to the onboarding process.
