Within the scope of this master thesis, we will investigate how security mechanisms can be used to safely store sensitive (especially protective) data on a smartphone. The basic assumption is that the amount of data to be stored has a size that exceeds the size of the secure element of a smartphone. The goal is that data stored in a database on the smartphone will remain secure even after a hacker attack on the operating system (administration rights in Android). The data should be read and written by an authorized application on the smartphone (Android app) and by an authorized web service.
