Abstract

This thesis deals with security, privacy, and anonymity on the internet. In this thesis are described tracking mechanisms and approaches that are being used to collect and send away users' personal information. Information that leaks using this tracking approaches can be used to identify user, to monitor and analyze his behavior on specific web pages and several leaked pieces of information can be misused (for example the leaked credit card number or password). In this thesis is described and tested the functionality and reliability of several current web add-ons providing the protection on the internet. New security increasing web add-on has been designed and developed to demonstrate a technique, that redefines and wraps the original JavaScript implementation of several functions and objects, the wrapping is executed before the visited web page starts processing the source code. Running the wrapping code at this time will ensure, that no other code in loaded web page will ever have access to the original implementation. This add-on is also well-tested. The final thesis' stage provides a great amount of possibilities to improve implemented add-on.

Keywords
