Mobile Application Identification Based on TLS Data
Borbély, Richard ; Matoušek, Petr (referee) ; Burgetová, Ivana (advisor)
This thesis deals with identification of mobile applications based on data from network protocol TLS. It conducts a research of values from the TLS handshake, specifically of JA3, JA3S and SNI values. The work represents an application that includes an algorithm performing a classification over TLS data. The results of the classification represent information based on which we can decide, if the identification of the apps was successful. This method allowed to identify 17 of the 18 given applications. The benefit of this work is the ability to identify mobile apps based on JA3, JA3S and SNI values and for example, it can be used in network administration.

Browser Fingerprinting Using Web Assembly
Škuta, Matúš ; Koutenský, Michal (referee) ; Polčák, Libor (advisor)
The main goal of this bachelor thesis is the implementation of device identification using Web Assembly technology. In this work we are discussing the existing methods of device identification, methods to prevent identification and ways to circumvent these barriers. We are also getting acquainted with the Brave browser, which seeks to reduce the identification of devices on the Internet. We are explaining how Web Assembly works, what are its positives, negatives and if we are able to bypass various defences against device identification thanks to this new technology. Next, we are looking at the several web APIs we are using to identify devices, and we are introducing a few extensions designed to prevent or completely limit device identification. Existing security extensions limit the activity of the Web Assembly, for example this work shows that the Web API Manager extension can neutralize the test page implemented in this work.

Material Position Tracking For Manufacturing
Plant
Sládeček, Michal
This article describes implementation of an indoor positioning system for tracking the location and movement of material and products through the manufacturing plant. The system is designed with regards to simple installation and low overall implementation costs. It utilizes method of Wi-Fi and magnetic field fingerprinting. The system employs a client hardware (active tag with Wi-Fi module and sensors designed for this project) communicating with a server software which does the mapping and fingerprinting processing. Final positioning data are then collected for further data analysis aiming to improve efficiency of manufacturing processes.

Fingerprinting - Past, Present and Future
Janotová, Martina ; Krupička, Jiří (advisor) ; Konrád, Zdeněk (referee)
1 Abstract Fingerprinting - Past, Present and Future The objective of the presented diploma thesis is to provide a comprehensive overview of findings in fingerprints area. Fingerprinting is a unique method enabling quick, inexpensive and reliable personal identification. To provide a comprehensive understanding of the presented issue, fingerprint reputation as ever-changing and continuously developing method is put into contrast with its contradictions and current problems. The first part of the thesis describes roots and genesis of the method from its beginnings in ancient realms up to date. The process of shaping of the knowledge in the field of fingerprints into a science is presented through the works of the most prominent fingerprints personalities. Despite the difficult beginnings, fingerprints finally reached the position of trustworthy and respectful area of forensic science. Due to that; the historical part follows the journey of fingerprints evidence into the police investigation and court rooms. Final point brings an attention to the establishment of fingerprinting in Czech criminal investigation. The main part of the thesis is dedicated to the practical aspect of fingerprints expertise. To provide a deep level of understanding, particular role of fingerprints in criminal investigations and its...

Fingerprinting - Past, Present and Future
Semera, Lukáš ; Krupička, Jiří (advisor) ; Konrád, Zdeněk (referee)
FINGERPRINTING - PAST, PRESENT AND FUTURE The objective of this thesis is to present the forensic fingerprinting as a scientific method which, although in comparison with other forensic sciences being one of the oldest, is not out-dated at all, quite to the contrary - it presents an ever-changing and continuously developing field of science. The objective is approached through three distinctive and yet intertwined chapters corresponding with the title of the thesis - past, present and future of the fingerprinting. They are also designed, at least in part, to capture this constant forward motion. Accordingly, the first chapter aims to describe briefly scientific roots of the method, the way it drew in its beginnings from various scientific discoveries, inspired by the rise of Darwinism. Particular emphasis is put on the description of the formulation and empirical confirmation of three physiological laws of fingerprinting that even today serve as its grounds. The second chapter deals with and tries to describe the current state of knowledge and particular methods used in detection, development and preservation of fingerprints, especially latent ones. To do this it seems to be necessary to describe briefly the anatomy and physiology of friction ridge skin, as it enables to fully comprehend the way in...

Liquid Chromatography Methods for Analysis of Actinomycete Secondary Metabolites - Potential Antibiotics
Kameník, Zdeněk ; Nesměrák, Karel (advisor) ; Cvačka, Josef (referee) ; Bosáková, Zuzana (referee)
(EN) This dissertation thesis contains scientific results achieved in the field of analytical chemistry, particularly liquid chromatography. The major part of the results has been published in prestigious international journals in five papers. In addition to that, relevant yet unpublished results have been included as well. In general terms, the work presented here contributed to the concerted efforts to tackle the current lack of novel antibiotics. Specifically, high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) techniques coupled to a variety of detection systems have been employed for analysis of antibiotics and actinomycete secondary metabolites. The first thematic part describes the development of liquid chromatography methods for analysis of lincomycin precursors, lincomycin precursor analogues, and lincomycin derivatives. The methods have been applied to study lincomycin biosynthetic pathway and obtain improved lincomycin derivatives by mutasynthesis. The second thematic part aims at investigating alternative approaches for analysis of antibiotics. Firstly, the core-shell particle and the sub-2 μm particle chromatographic columns were compared. The core-shell particle columns compatible with HPLC proved to be a convenient alternative to the...

Invisible watermarking of digital signals
Pacura, Dávid ; Horák, Karel (referee) ; Petyovský, Petr (advisor)
Cílem téhle práce je navrhnutí nových technik pro robustní neviditelné značení digitálních signálů. Nejdříve je prezentován současný stav tohoto odvětví a dostupné softwarové řešení. Poté následuje návrh několika algoritmů pro neviditelné značení, přičemž každý z nich je založen na jiném principu. Dále je připravena sada digitálních testovacích signálů společně s testovacím softwarem pro otestování navržených řešení a jejích porovnání s vybraným dostupným softwarem. Poté následuje srovnání naměřených výsledků, výkonu a jejích diskuze.

Operation System Detection in Network Traffic Using IPFIX
Vymlátil, Martin ; Grégr, Matěj (referee) ; Matoušek, Petr (advisor)
This task deal with detection of operation system in network traffic using IPFIX. The main idea of this task is based on the fingeprinting, when we use information from IP and TCP headers to determine operation system. This data represent a unique signature of the operation system. Based on the information a plugin for the FlowMon probe was designed and implemented. Plugin was tested on live network traffic and pcap files.
