COVID-19 disease, caused by the SARS-CoV-2 virus, has led to many changes in the movement of people in different environments or even between different countries. Vaccines began to be administered more than a year after the pandemic has started. Following the administration of the vaccine, various ways were sought to identify the vaccinated people very quickly, in order to allow access to various areas, such as supermarkets or secure areas at airports. Thus, digital certificates were issued for attesting the vaccination, testing or recovery of that person. These certificates contain a QR code that can be scanned using an application installed on a mobile device. Research has sought to identify a more secure way to identify the holders of such a certificate. After vaccination, we consider it’s useful to insert the biometric data of the iris or fingerprint in a national or international database, from where it can be accessed by all institutions authorized to verify the validity of such a certificate. During the research, the human iris was taken as a biometric feature, trying to find ways to scan it in real time and without a great interaction of the user with the video capture device. One of the biggest problems with such an approach is the exact connection between the person whose iris was scanned and the proof of having a COVID digital certificate. The idea was to replace the need to hold a certificate in printed or digital form with the image of the human iris, which in polar coordinates is quite similar to that of a QR code.
