Mobile application for anonymous communication
Krajanec, Štefan ; Člupek, Vlastimil (oponent) ; Dzurenda, Petr (vedoucí práce)
Instant messaging applications noted significant grow especially in the last decade. In fact, the Internet communication is cheap and convenient way how to communicate with distant people. However, this grow of user communication and data exchange through the online world impacts user security and privacy, as it was also shown recently by WhatsApp privacy issues. Firstly this article evaluates security and privacy issues of current mobile messaging applications. Secondly, we design our basic open source solution with the focus on security, privacy, and user centric features. Furthermore, we provide proof-of-concept implementation of our system

Mobile application using Google beacon technology
Krajanec, Štefan ; Hajný, Jan (oponent) ; Dzurenda, Petr (vedoucí práce)
This Bachelor thesis focuses on utilizing beacon technology in Android applications. Beacon technology allows for determining an approximate distance of the user from the beacon.. In order to verify the reference numbers given by the manufacturer we conducted an observation to measure the power of the received signal in reference to distance. 3 brands of beacons were tested, Kontakt.io, PROXioT and IBKS. The observasion has been iterated in an open field setting. Findings from this observation was implemented into an application designed for shopping mall marketing. The application, after getting closer to the beacon distinguishes between different behaviour types; behaviour as an instant notification, as a position log into a database, as a time stamp log (time spent near the beacon) into a database and as a conditional response. The aim was to resolve the problematics of communication with the beacon as universally as possible so the impletation into other projects would be as simple as possible. The aforementioned app is the output of this thesis.
