This thesis presents a hybrid information security approach for data on physical documents. This system, called CryptoPaper, allows portions of a physical document be printed with a machine-readable code. This code contains original data and related information security properties. To read this code and access the encoded data, a scanning device with suitable image recognition technology is used. Using a cloud-based access control system, it can be ensured that only authorized users can interpret the machine-readable code and additional security properties can be verified.
