SeCuUI: Secure and Fast Data Submission to Public Terminals Using an Auto-Complete Mechanism
Diploma Thesis, Ludwig-Maximilians-Universität München, 2009 (bib)

Security at public terminals is an often discussed issue today. Many different ways exists to steal private data from someone using such a terminal. This thesis tries to present a new approach to this problem, using the mobile device of the user to enhance input security. SeCuUI Secure Custom User Interface is a software suite consisting of a client software and a framework to develop server applications. The client can be used with any public terminal running a software based on the SeCuUI framework. Using a device protected from modifications in the close proximity of the user makes it much harder to spy on any data she enters. To speed up the process the client remembers previously entered values and proposes them in future sessions. The framework and the client have both been evaluated in a user study using a demo-server based on the framework. This thesis contains explanations to all work done on the software as well as information on the planning, conduct and outcome of the user study.
