Browser and User Fingerprinting for Practical Deployment
Vondráček, Tomáš ; Malinka, Kamil (referee) ; Polčák, Libor (advisor)
The aim of the diploma thesis is to map the information provided by web browsers, which can be used in practice to identify users on websites. The work focuses on obtaining and subsequent analysis of information about devices, browsers and side effects caused by web extensions that mask the identity of users. The acquisition of information is realized by a designed and implemented library in the TypeScript language, which was deployed on 4 commercial websites. The analysis of the obtained information is carried out after a month of operation of the library and focuses on the degree of information obtained, the speed of obtaining information and the stability of information. The dataset shows that up to 94 % of potentially different users have a unique combination of information. The main contribution of this work lies in the created library, design of new methods of obtaining information, optimization of existing methods and the determination of quality and poor quality information based on their level of information, speed of acquisition and stability over time.

A Web Presentation of JShelter Project
Krčma, Jan ; Polčák, Libor (referee) ; Bednář, Martin (advisor)
This thesis deals with creating user-friendly web presentation of the project JShelter, in which its advantages in terms of the safety of its users when navigating the World Wide Web are highlighted, so that their anonymity and at the same time the functionality of the visited sites are sufficiently preserved. Above all, the result provided by the JShelter browser extension against tracking the user based on the deviation of his internal clock and also the confirmation of the same-origin policy protection will be shown.
