Global pandemics are dramatically increasing the demand for medical personal protective equipment (PPE), leading to a global increase in the number of counterfeit printed or digital certificates produced by professional fraudsters. This vulnerability is compounded by the fact that current certificates lack security features. As a result, current certificate authentication consists of verifying that the data provided is plausible and that the printed documents have been issued by authorised bodies. This presentation illustrates the current problem and status of PPE certificate authentication. It is divided into two parts. In the first part, a concept for a semi-automatic certificate verification is proposed. In the second part, the problems of the current authenticity check are discussed. Possible improvements are also discussed, especially with regard to security and machine readability.
