Photos with Timestamp
Mlejnek, Matěj ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
This thesis describes the design and implementation of a system for creating timestamps for photos in groups. It deals with the ways the group timestamp of multiple photos can be verified all at once. The whole system can be split into four parts. The first part is a mobile application, in which photos are taken by the user. The second part is the server on which photos are backed up and which relays the photos to a server that makes group timestamps. The third part is the server itself that creates the timestamps. The fourth part consists of user tools for retrospectively checking the existence of a valid group timestamp.

Web Application for Certificate Management
Kobyda, Simon ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
Cieľom tejto práce je vytvorenie softvéru na získanie a správu X.509 certifikátov. Hlavný dôraz je na poskytnutie múdreho a intuitívneho uživateľského rozhrania, ktoré by dovolilo spravovať certifikáty aj administrátorom, ktorí nemajú o nich veľa znalostí. Práca je implementovaná s technológiou React ako plugin pre Cockpit, vďaka čomu si nájde svoje miesto aj vo väčšom obraze Red Hat portfólia.

Confidential Information Storage for Windows Mobile System
Štorek, Vojtěch ; Malinka, Kamil (referee) ; Hanáček, Petr (advisor)
Confidential information such as passwords, cryptographic keys, certificates, etc. are used every day on various places. Mobile phone can be a good storage for such informations, but is necessary to ensure data security. Main goal of this project is to create a program for Windows Mobile phones which will keep all the informations in one place protected by password. Designed program lets user to store passwords, cryptographic keys, various files, important contacts, credit card numbers, etc. Some of the stored informations can be downloaded from remote server via FTP protocol or from smart card. It is also possible that two clients will synchronize their informations via Network and other usefull functions.

Fair Trade and developing countries in international trade
Lužná, Nikola ; Bič, Josef (advisor) ; Janković, Vukica (referee)
The thesis is focused on the analysis of the Fair Trade concept. Its main goal is to evaluate the potential of the market in the Czech Republic based on the analysis of the development of Fair Trade in the rest of the world and successful strategies used on various national markets, but with special emphasis on the strategy in the United Kingdom, where the concept is the most developed. Firstly, it describes the origin, formation and worldwide expansion of the movement. Afterwards, it characterizes basic principles and standards that have been set up and have to be kept by all the participants through the whole system. Secondly, I focus on the commodities that are sold under the Fairtrade Mark with an emphasis on the most significant ones, coffee and bananas. The general overview of the development of Fair Trade on the world market leads me to the market of the United Kingdom where I evaluate the causes of its success. Finally, I analyze the market in the Czech Republic and based on the strategies discovered on previous national markets I suggest those which could be applied on this market as well.
