The requirements: Data security is the priority
Despite the acute situation and the search for a quick and pragmatic solution, no compromises could be made in terms of safety. Sensitive health data must be protected in digital environments. Data security is a central aspect regarding OZG implementations. At the same time, it is important to the city of Cologne to make the application user-friendly and unbureaucratic.
In addition to these aspects, there were the following requirements for the application:
• For Cologne residents who are less digitally savvy, there should be the option to print out the certificate.
• From a user perspective, the application had to be compatible with existing digital measures to combat pandemics such as the Corona warning app and the CovPass app.
• In the backend, the application should also be compatible with existing structures such as digital contact tracking (DiKoMa).
• The evidentiary value and security against forgery should correspond to the standards of the digital vaccination certificate and should also be valid throughout Europe with the so-called DCC conformity.
There are also some technical requirements for a digital recovery certificate. The application must be both data-efficient and secure. In addition, this should run on the local infrastructure of the city of Cologne. During development, it is important to take many stakeholders into account (project management city of Cologne, health department, press office, IT administrators, BMG and their consultants, Ubirch and Railslove) while remaining agile. SIDESTREAM was selected as a suitable partner to implement these high requirements at a high quality level.
