This thesis deals with problems of identification cards at the University of Economics, Prague. Its primary goal is to consider and evaluate the possibility of a transfer of the ID card management into the ISIS system. The thesis consists of four parts. The first one offers a complex analysis of the ID card management at the University. The second one analyses two ID card management systems: the NESA system, which is being used at the University now, and the ISIS system, which could also be used for the ID card management. The third part includes a proposal of adjustments in the ISIS system, which would make its ID card management implementation comply with the University's needs. The proposal describes general features of the system, relations to its environs and a graphical user interface. Finally the last part covers the actual state of the project and its differences from the proposal offered in the thesis. Information sources for the thesis were legal norms, University regulations and internal documents as well as the author's knowledge and experience gained through several years of the NESA system maintenance and numerous consultations with the University ID card management staff and ISIS developers. The main assets of this thesis lay in the comprehensive view of the ID card management at the University along with the proposal of the new ID card management system, which is to be integrated into ISIS.

The thesis deals with security of the Android operating system, both general security features and options for storing sensitive data. The suitability of Android KeyStore for storing sensitive data and the possibility of using the secure element for safe application calculations and smart card emulation are discussed. Using Host-based Card Emulation for contactless smart card emulation is discussed. The performance analysis of modular arithmetic operations for numbers with high bit length is examined. Following these analysis, an implementation of application for software contactless smart card emulation of HM12 and HM14 cryptographic protocol is proposed. And an implementation of application for verifying smart cards with these protocols is proposed. Also scheme for secure storage of sensitive data is proposed.

Cílem této práce je vytvořit systém, který bude vylepšovat zážitek z hraní deskových a především karetních her, promítáním relevantních multimediálních informací do herního prostoru. V první části jsou popsány přínosy deskových a karetních her. Dále jsou představeny principy rozšířené reality a jejich použití při návrhu takového systému. Navržený systém je rozdělen na tři moduly. Prvním z nich je modul, který analyzuje stav hry na stole v reálném světe --- poskytuje informace o aktivitě hráčů a jaké typy herních objektů se vyskytují na stole. Druhým je modul, který se stará o řízení celého systému, poskytuje uživatelské rozhraní pro kalibraci systému a implementuje stavový prostor hry, pro kterou je systém určen. Třetím je modul, který poskytuje výstup systému --- vytváří multimediální obsah, který je po-té promítnut na stůl, a je relevantní k aktuálnímu stavu hry. Na závěr je navržený systém implementován pro karetní hru Bang, otestována jeho schopnost udržovat krok se stavem hry v reálném světě a provedeno testování na uživatelích.

The main goal of this thesis is to compare the quality of customer service between the Mobile Network Operators (MNOs) and Mobile Virtual Network Operators (MVNOs) on the Czech mobile telecommunication market. The mystery shopping method is used as the source of data for the comparative analysis.

This diploma thesis on the theme Improving quality of GSM Banking services for T-Mobile customers deals with detailed analysis of the selected product, which the T-Mobile company has been mediating to all it´s customers for years. This analysis resides in comparing of GSM Banking services with other mobile operators operating on the contemporary Czech market. My thesis contains general theoretical and concrete practical resources, which offer possibilities of improving and innovation of the present situation.

This diploma thesis deals with design, realization and analysis of security and surveillance systems for buildings and spaces containing advanced components. One of the main design's parts is dedicated to intruder alarm system, access system, attendance and CCTV systems with the possibility of automatic motion tracking. Controlling and monitoring of particular subsystems is possible both locally and remotely from a computer via a web interface or by means of a software. The access to camera system from a mobile phone is also possible. IAS/ACS systems also enable controlling and transferring information about their state via SMS. The designed system was realized completely and its operating was demonstrated. The realization is described in detail including illustration of configuration of particular components. A security analysis and a possible future development of the project is summarized in the conclusion.

Private deck of cards created during six-month survey and documentation of daily experiences. The package contains 49 cards and it is inspired by a set of 78 tarot cards. Text content - reverse side of the card was created using diary notes. Face side of the card was chosen as a representation of processes taking place usually in days when the card was read.
