Free speech on the Internet and censorship as a way to protectusers' privacy
Brišová, Jana ; Moravec, Václav (advisor) ; Osvaldová, Barbora (referee)
The aim of this bachelor thesis is to provide a complex analysis of free speech on the internet, violation of this right and ways how to protect own privacy in cyberspace. It is based on a theoretical exploration of protection of free speech, right to privacy and collision of these rights. Based on this theoretical analysis this thesis seeks to provide a comprehensive analysis of the cyberspace as a space enabling free speech as well as violating the right to privacy. This thesis also explores the responsiveness of the Internet to the users' demands on privacy, violations of the right to freedom of expression, and censorship of the Internet, as demonstrated by the case studies of countries taking these steps. This is followed by a research of ways to circumvent Internet censorship, including the possibility of anonymity on the Internet. Anonymity is also discussed as a tool to protect privacy as well as source of dangers.

Privacy protection in cloud
Chernikau, Ivan ; Smékal, David (referee) ; Dzurenda, Petr (advisor)
In the Master’s thesis were described privacy protection problems while using cloud technologies. Some of the problems can be solved with help of homomorphic encryption, data splitting or searchable encryption. These techniques were described and compared by provided security, privacy protection and efficiency. The data splitting technique was chosen and implemented in the C language. Afterwards a performance of the implemented solution was compared to AES encryption/decryption performance. An application for secured data storing in cloud was designed and implemented. This application is using the implemented data splitting technique and third-party application CloudCross. The designed application provides command line interface (CLI) and graphical user interface (GUI). GUI extends the capabilities of CLI with an ability to register cloud and with an autodetection of registered clouds. The process of uploading/downloading the data to/from cloud storage is transparent and it does not overload the user with technical details of used data splitting technique.

Legal aspects of the current personal data protection developments
Tumpachová, Kateřina ; Pítrová, Lenka (advisor) ; Svoboda, Petr (referee)
This doctoral thesis is divided into ten chapters in which, together with the introduction and conclusion, it aims to describe and analyse the current development of legal regulation of personal data protection, especially from a substantive law perspective. The thesis analyses the existing legal regulations of the European Union, implemented in the legal frame of the Czech Republic compared to the new General Data Protection Regulation, which unifies the legal framework for the personal data protection in the whole European Union. The first chapter of the thesis describes in brief the development of the personal data protection legal framework, from the establishment of the right to personal data protection in human rights declarations to the gaining its independence from the right to privacy. Furthermore, the relevant OECD Guidelines and Convention 108, which plays a crucial role in the field of personal data protection, are described. The development of the legal regulation of personal data protection in the European Union, together with the development of legislation in the Czech Republic, which also meant the necessary implementation of EU regulations into the Czech legal order with the accession of the Czech Republic to the European Union, are described. The second chapter describes in detail...

Anonymization of users when collecting network traffic
Hamár, Lukáš ; Blažek, Petr (referee) ; Sikora, Marek (advisor)
This thesis deals with anonymization of data, which could lead to disclosure of the identity of end users in network traffic. Work describes algorithms by which individual data parts are anonymized and also tools which use these techniques for network traffic anonymization. The next part of the thesis describes construction of a laboratory network, in which is the network traffic captured, containing pcap and NetFlow data. With using of the captured data, the anonymization tools are tested and the results are compared. In the last part of the thesis is created graphical interface for one of the tested anonymization softwares.

Darknet networks as a way of protecting internet users' privacy
Plevný, Marek ; Sigmund, Tomáš (advisor) ; Čermák, Radim (referee)
In this age when information technologies became inseparable parts of our lives we can hardly imagine for example living without internet. There is a phenomenon connected with internet and that is large scale collection of data about internet users and their activities. Because of this fact, it is important to protect our internet privacy as a very important aspect of our lives. This work examines large scale collection of data about users internet activities. During this work, different methods and reasons for this largescale data collection are examined. Later, different ways how internet users are protected by law or how they can protect themselves are examined. One of the ways how internet users can protect their internet privacy is by using so-called anonymizing networks connected with a phenomenon called Darknet. This work examines if it is possible by ordinary internet users to adapt this method of internet privacy protection.
