* [Fake CDC vax cards now being sold to anti-vaxxers](https://lists.w3.org/Archives/Public/public-credentials/2021Apr/0077.html) Moses Ma(Thursday, 8 April)
Just wanted to share this with those working on C19 vax certs:
The security firm DomainTools claims to have seen authentic-looking CDC cards selling for as little as $20 each on domains like covid-19vaccinationcards[.]com, which features a Let’s Encrypt TLS certificate. “Though selling a printed card is not necessarily illegal, the pricing, logo and cardstock of these ‘vaccination records’ demonstrate a level of intent to pass as legitimate cards from the CDC,” explained DomainTools senior security researcher, Chad Anderson.
Israeli security firm Check Point reports that fake American and Russian vaccination certificates are being sold online for between $100 and $200. Fake COVID-19 negative test results cost as little as $25, while (likely fake) COVID-19 vaccine sells for about $500 per vial.

As some of you know, a few of the members in the W3C Credentials Community Group have been working on a Vaccination Certificate Vocabulary[1]. The World Health Organization has recently published a Release Candidate data model dictionary for Smart Vaccination Cards[2]. The CCG has also been working on a Verifiable Credentials HTTP API[3].
The WHO guidance covers 28 types of vaccines that we (as a global society)
depend on, including Measles, Smallpox, Polio, Yellow Fever, COVID-19, and
others. We (Digital Bazaar) thought it might be interesting to see if we could
create an interoperability test suite for the WHO Smart Vaccination Card work using the tools listed above.
...
- A test suite containing 1,624 tests covering the
28 vaccine types in the WHO vocabulary.
- 7 independent vendor implementations issuing and
verifying each others WHO Smart Vaccination Cards.
- 1,623 passing tests demonstrating true
interoperability!

COVID-19, Good Health Pass Collaborative, Rules Engines, Verifiable Presentation Requests
The transition from contemporary access controls to SSI will need a metalanguage for access control rules in order to allow verifiers and holders to trust the transaction. Not everyone will know how to write the complex branching and contextual rules logic that make up real life access controls.
Solution assumption with the Good Health Pass is revoking is not necessary as VCs are short lived (solution to invalid credential). Issuers will re-issue vs. revoke
In many cases, labs are providing incorrect information in vaccination records, which need to be re-issued
· Still need to notify the holder that their (current VC) is invalid and they need to take action to resolve
· Issuers asking what if we make a mistake – (re-issue)
· Holders having problems findin there vaccination VC
· Many of the unresolved issues are governance/policy related (for which the “health authorities”) have not worked out the details
· Policy providers are applying the brakes through in-grained bureaucracy to produce a perfect standard for their jurisdiction vs. rapidly evolving a common standard and “usable solution” in the short term.
· Unclear on how to get VC and underlying data into the hands of holders, particularly as holders don’t have the technology and skills to manage their health data.
· Data privacy is an issue across each of the implementers and users of the Issuer, Holder and Verifier roles. Lack of common understanding and agreement on how and who owns and controls the data
· WHO standard will likely be adopted in the Global South (hemisphere)
· GHP looking to paint a forward looking common picture, including interim solutions (iterate standards)
· The number of players (and their levels of understanding/expertise and agreement with the current direction) alone makes consensus very difficult
· Paper credentials have been getting consensus on interim solutions.
· W3C and WHO are great candidates.
· Affinidi is making a universal verifier application (https://www.affinidi.com/)

Beneficence – the duty to ‘do good’.
Non-Maleficence – the duty to do ‘no harm’.
Justice – to treat all people equally and equitably for the benefit of society.

Do we need a Covid vaccine passport whether this is paper based or digital?
If there is or are contexts where a vaccine passport would be more beneficial than not, what are the technical principles, implementations and considerations that need to be met to ensure that they are implemented to comply with medical ethics and law?
After all this is personal health information and therefore should be treated as such.
What problem are we really trying to solve with a Covid Vaccine Passport, Covid Passport, ‘Covid’ credential, digital green certificate, or any other named health pass solution?
To do this there needs to be a basic understanding of this infectious disease, what tools we have currently to deal with it and address assumptions that have been made, many of which may change or are yet unknown such is the dynamic nature of a pandemic.

Health passes, though, are much more flexible as they provide multiple options. They can still be used as proof of vaccination, if the user chooses to share their health information in this way.
But, importantly and in a crucial difference from vaccine passports, they can also be used to securely display a test result, such as a negative PCR or rapid antigen test (also known as lateral flow tests) today. Additionally, they are also future-proofed for options such as rapid antibody test results when those come into play on a large scale.

### Version 1 of the Ontario COVID Vaccine Certificate is a cumbersome experience that needs some work
What I observed is NOT a user-friendly experience for either the customer or the business. For the experience to be improved it needs to be a single presentation operation of either a paper or digital certificate that the business can verify in one step.
The advantage of a paper and ID card presentation ritual is that it is difficult to hack. So if we are going to improve the presentation with a single credential as above, privacy and security MUST be protected.
