The European Commission is creating Digital COVID Certificates (also known as Digital Green Certificates) to facilitate safe free movement inside the EU during the COVID-19 pandemic. Digital COVID Certificates will be valid in all EU Member States. They will form a digital proof that a person:
The QR code contains a secure digital signature to protect it against falsification, PDF digital signatures are a well-established technology, are widely used, and are a key feature of iText 7 Core.
Tip: Using iText DITO’s data binding capabilities makes designing certificates such as these easier, and can generate 1D and 2D barcodes from input data. iText DITO also accepts JSON as a data source, which was indicated on page 4 of the EU eHealth Network Trust framework Outline:
Tip: Designing PDF templates with iText DITO could be ideal for generating multiple versions of one certificate, thanks to built-in support for complex writing systems.
Digital COVID Certificates will be available, free of charge, in digital or paper format. It will include a QR code to ensure security and authenticity of the certificate. The Commission will build a gateway to ensure all certificates can be verified across the EU, and support Member States in the technical implementation of certificates. The Commission is also work with the World Health Organization to ensure that certificates issued in the EU can be recognized elsewhere in the world as well.
The EUDCC (EU Digital COVID Certificates) consists in addition to the twenty-seven EU Member States, non-EU members Norway, Iceland, Liechtenstein and Switzerland are also party to EUDCC. Although the United Kingdom is not taking part in the EUDCC program, it has instead incorporated a vaccination status verification in the NHS (National Health Service) mobile app.
Several member states were very quick to have connected to the EUDCC program and started issuing or validating the first certificates using their national certification implementations:
In Belgium, a web application will be made available for digitally requesting a vaccination certificate, a test certificate and a certificate of recovery after authentication of the identity.
The vaccination certificate, test certificate and certificate of recovery take the form of a PDF which can be saved or printed.
A mobile app, named CovidSafeBe, will also be available on Android and iOS for digitally requesting a vaccination certificate, a test certificate and a certificate of recovery after authentication of the identity. This app permits to store the certificates in a wallet.
The model of the certificates is defined by the European Union, but the creation of the document/certificate is performed by each member state (Belgium in this example). The EU also states it needs to be foldable so that QR code is on the back and personal data on the inside (not directly visible)
a broker provides a RESTfull API that, when a person requests a certificate via the Personal Health Viewer or another user interface creates the requested certificate in the form of a PDF based on this data (via a free of charge open source PDF generator); - Corona-tracking.info
iText 7 Core is open-source technology, and like its predecessor iText 5 is available for free under the terms of the AGPL license. While iText 5 (and even iText 2 in some cases) are still used in some applications, it’s important to note they are both end-of-life and no longer being developed. iText 2 even has important security and IP matters to take into account.
Since the inception of iText 2, iText Software continued to evolve its widely-used library, and it has long resolved the security and IP matters inherent in iText 2. In addition, it has vastly expanded the functionality in later versions of our leading PDF library. Check out the latest one, iText 7 Core offering numerous improvements and benefits.
