Computer Identification Using JavaScript Timestamps
Jireš, Michal ; Večeřa, Vojtěch (referee) ; Polčák, Libor (advisor)
This thesis deals with remote computer identification based on its internal clock skew. This clock skew will be determined using JavaScript timestamps. The goal of this thesis is to create web page, that will use clock skew to identify computer. This web page will also be used to test time distortion capabilities of browser extension JavaScript Restrictor. Web page will try to identify computer using different security presents thus testing their efficiency.

JavaScript Restricting Web Extension
Timko, Martin ; Matoušek, Petr (referee) ; Polčák, Libor (advisor)
The purpose of this thesis is to functionally expand the browser extension prototype created by Ing. Zbyněk Červinka, focused on the privacy protection of the user during his web browsing. Acquired facts about the function of existing tools for safety and privacy protection, such as technology JavaScript Zero, were used in the solution, which was created by employing a technique of encapsulating JavaScript objects and functions. This allows greater anonymity and safety for users during web browsing. The extension was tested and published under the title JavaScript Restrictor. The main benefit of this thesis is the increase of safety from attacks and increase of anonymity linked to the user data harvesting.

Porting of Chrome Zero Functionality to JavaScript Restrictor
Horňák, Peter ; Večeřa, Vojtěch (referee) ; Polčák, Libor (advisor)
This thesis deals with improvements of security and privacy protection of web browser users by enhancing functionality of web browser extension called JavaScript Restrictor, which prototype was created in order to protect users on web. Within this thesis are analyzed security measures realized by tool Chrome Zero, which implements measures against microarchitectural attacks, attacks abusing high resolution timers and abuse of JavaScript engine. Thesis evaulates topicality of measures and integrates selected into JavaScript Restrictor. Measures are tested and evaluated from every day use point of view.
