Abstract
Since the introduction of Electronic Machine-Readable Travel Documents (eMRTDs) the gap in security between eMRTDs and Machine-Readable Travel Documents (MRTDs) has been a cause for concern. In 2016, the International Civil Aviation Organization (ICAO) released the report "Visible Digital Seals for Non-Electronic Documents" containing a standard that combines the extension of existing principles and infrastructure in the travel document ecosystem with barcode symbols to offer a remedy to increase security in MRTDs. This thesis explores design possibilities for the use-case of a new type of short-term travel documents, Single Journey Passports, with the application of Visible Digital Seals to verify that its application achieves higher security assurance.
