Digital Steganography and Steganalysis
Poremba, Tomáš ; Wiglasz, Michal (referee) ; Strnadel, Josef (advisor)
This thesis deals with digital steganography and steganalysis. It explains the significance of both disciplines and gives a brief overview of the history in the given fields. The paper separates existing steganographic and steganalytic methods and describes the attributes of various branches of steganography. With respect to the chosen field of steganography (the image steganography), the paper narrows down the set of suitable steganographic and steganalytic methods, whose features are then described in detail. The results of the thesis inlcude experiments that verify the features of chosen steganographic methods and evaluation of steganalytic methods and their success in detection of steganography.

Trouble Ticket Management and Communication System
Poremba, Tomáš ; Křivka, Zbyněk (referee) ; Rychlý, Marek (advisor)
This bachelor thesis deals with a design and an implementation of a ticket management and coummunication system. It explains the problem of incident and problem management and a documentation of their lifecycles. The thesis compares existing solutions that handle the problem. A description of the problem focuses on subprocesses needed for successful mastering of incident and problem management. These processes are included in the design and the implementation of a system. The system is built with a help of .Net platform and JavaScript framework AngularJS. Part of the implementation uses integration with a project management system Podio. The system is developed in co-operation with the company WebStudy and its development respects exerted policies.
