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.

At the present time the widely usedWi-Fi networks provide comfort by zero configuration settings. However it leads to serious privacy issues. The article is focused on user information which can be extracted from service communication. The article presents several ways how to collect these information and introduces the platform for collecting user data. In the first part there is described the available network discovery mechanism followed by section about designed methods for obtaining user information. The last part describes the implemented platform in detail.
