Digital footprint on own computer and the Internet
Skalický, Pavel ; Halbich, Čestmír (advisor) ; Gojda, Ondřej (referee)
The aim of my work is finding ways of how the user is able to control their digital footprint. Finding a negative impact on the user and his identity. All tests performed on the freely available tools. At the beginning of the introduction to the concept of digital track, different views on these tracks. There is described the emergence of digital tracks and then formulated a precaution against leaving digital traces. Said there are risks for when leaving digital traces. In the practical part, a test tool for hiding digital tracks, and detecting tracking tools. Getting to what extent can protect against attacks. The subsequent recommendation to certain instruments.

Digital footprint on own computer and the Internet
Kleinander, Michal ; Halbich, Čestmír (advisor) ; Pavlík, Jan (referee)
This work is focused on digital footprint and security. The basic terms and distribution of digital footprints are briefly described in the chapters. There are also described potential risks and threats that may occur due to misuse of digital footprints. The theoretical part is ended by the ways to control digital footprints and their management including the overview of tools. The practical part is focused on testing and comparison of selected tools for privacy protection. On the basis of comparison tools is provided a suitable solution in protection of digital footprint.

Digital footprint on own computer and the Internet
Tomovič, Štefan ; Halbich, Čestmír (advisor) ; Pavlík, Jan (referee)
The main aim of this thesis is to characterize various types of digital footprint and describe the methods of data protection. This conservation uses freeware tools. The theoretical part describes the types of digital footprint, the possibility of misuse of digital footprint and attacks on the computer or data. The next chapter describes the used freeware tools. Their basic characteristics and their use. In the practical part, these instruments are divided into three groups, depending on the region the problems that it solves. According regions are also chosen criteria. In the last part, these instruments are tested each other, using multi criteria analysis.

Google Chrome OS - theory and practice
Pavelka, Martin ; Halbich, Čestmír (advisor) ; Radomír, Radomír (referee)
In my thesis, I focus on the operating system Google Chrome OS, determination of its characteristics, definition of target group of the operating system's users and comparison of available applications with those available for other operating systems. In the theoretical part, historical development of Google is analysed first, followed by the issue of Google Chrome web browser and analyse of the operating system Google Chrome OS. The practical part starts with evaluation of survey on the operating system Google Chrome OS and is followed by multi-criteria analysis of variants comparing various categories of applications available for the operating system Google Chrome OS and other operating systems, in this case represented by the operating system Microsoft Windows 8.1 and distribution of Linux operating system Ubuntu 14.04 LTS.

XML and OpenDocument Format standards and their use in practice
Pluhař, Marek ; Halbich, Čestmír (advisor) ; Pavlík, Jan (referee)
The bachelor thesis deals with XML and OpenDocument Format. The entire work is divided into theoretical and practical part. The theoretical part is divided into two separate sections. The first is devoted to the description of the XML format. The second is related to the OpenDocument Format. The work clearly explains the issues of studied topics.
The practical part is also divided into two sections. The first one is devoted to the use of XML and the second to creation of ODF macro. In the XML area was done converting XML file into HTML output using XSLT. In the ODF area was created ODF macro, which exports file in program Calc into PDF format. The practical part verified knowledge gained in the theoretical part and allowed to fulfill the both practical aims.

Techniques of website optimization
Vodička, Václav ; Lohr, Václav (advisor) ; Halbich, Čestmír (referee)
This work analyzes efficiency of selected optimization techniques for websites. The work includes basic concepts and principles that are used for interpretation of results and demonstration of use of the optimization techniques.
To obtain data to evaluate the effectiveness of the optimization techniques are used two tools from Google Inc. The first is Google Search Console (previously Webmaster Tools) and the second is Google Analytics. In these tools are collected data fixed period of time before and after use of optimization technique.
The analyzed techniques are link building, use of structured data, changing of title and description, malware on website or use of Sitemap file after creation of a new version of website. The aforementioned techniques are shown either annotated code in case of using programming language, or verbally described and accompanied by pictures.
The benefit of the work is to gain knowledge that can be used in the selection of appropriate optimization technique that will lead to increase website traffic or to determine the causes of its decrease.
