Sensor Pattern Noise Analysis and Identification
Král, Benjamin ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This work is about extraction of sensor pattern noise of digital camera which is additive noise that is present in every digital photograph and which is unique for every camera. Suitable sensor pattern noise extraction methods are discussed for noise extraction and comparation with aim to find out with which camera the digital picture was taken. Best method is implemented as an application. The work describes few experiments that are reviewing the application performance based on many different photographs given to the application.

Educational Game of Motivation on the Android Platform
Kučera, Martin ; Očenášek, Pavel (referee) ; Kreslíková, Jitka (advisor)
The aim of the dissertation is to create a prototype of an educational game which should help students with the choice of future their studies. To this end, the game introduces the topic of logic systems in a non-threating interactive way with clear illustrative examples. The theoretical part of the work deals with the background knowledge necessary in order to design the game. It explains logic systems, gates, flip-flop circuits, and explores various aspects of game genres with primary focus on puzzle games and their history. In addition, the dissertation presents some of the issues related to cross-platform development of games for both mobile and computer platforms, and provides brief descriptions of several popular cross-platform libraries. Lastly, the work introduces and compares several chosen applications created as a supplementary material for teaching logic system.

Risk Behaviour of ETL Processes in a Data Warehouse
Košinová, Kateřina ; Očenášek, Pavel (referee) ; Bartík, Vladimír (advisor)
This thesis is about hazardous of ETL processes in their data warehouse. In the first part of this thesis I have defined the ETL processes and the aim of this thesis. The second part is about theoretical solutions needed to create a data warehouse, the definition of ETL processes and discovering potential risks. The third part is about discovering potential risks of ETL processes using an analysis and risk assessment. This part also includes a control of the potential risks. The fourth part concentrates on modifying the ETL processes to prevent potential risks. An important part of this chapter is an emergency plan containing necessary processes which must be applied in case of a risk. The fifth part of this thesis is a summary of all knowledge found during the analysis and development.

Forensic Analysis of Network Connection in OS Linux
Jurinek, Róbert ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
This thesis focuses on forensic analysis of network connection in operating systems based on Linux kernel. The paper is divided into chapters that describe principles of digital forensics, packet processing inside Linux kernel and compare forensic software tools. This knowledge is then applied in design of application for network connection forensics in Linux. Designed application is implemented and used in practical process of digital forensic analysis. In conclusion possible extensions are proposed.
