Use of blockchain technology for recording changes in cloud storage
Spolek, Jaroslav ; Malina, Lukáš (referee) ; Dzurenda, Petr (advisor)
The bachelor’s thesis focuses on the design and implementation of a module to ensure data integrity on an existing cloud storage platform, Nextcloud. The theoretical part deals with issues related to the security of cloud storage services, and subsequently, it provides a general introduction to blockchain technology and its implementation in the form of Ethereum blockchain technology. Included are the basic principles of Ethereum blockchain technology and the principles of smart contracts. In the practical part, the design proposal, tools used during the implementation, and the implementation of the data integrity module utilising blockchain technology are presented. The results of the system testing are then analysed, and external influences and factors affecting the cost and operation of the module are identified. This analysis concludes with a proposal for future improvements addressing the current shortcomings of the module.

Modular Application for the Management of Cyber Polygons
Janek, Samuel ; Rychlý, Marek (referee) ; Hranický, Radek (advisor)
The goal of this work is the design and development of version 2.0 of the Brno University of Technology Cyber Arena (BUTCA) platform. The BUTCA platform is used for cybersecurity training. The reason for the creation of this work are new requirements that require extensive changes in the core of the platform itself. For this reason, a part of this work is dedicated to the reimplementation and subsequent expansion of the existing system. In order to meet some of the new requirements, the platform is extended with an authentication server (AS), which is implemented as a separate application. Both the AS and the platform use a client-server architecture, with the server part being implemented as a web API and the client part as a Single-Page Application (SPA). The implementation of this work will expand the use of the platform among institutions, which, in the case of version 1.0, would have problem with processing of their sensitive data by external institution.

Cognitive Game Battery: Assessing and Identifying Deficits in Memory, Attention, Problem-Solving, and Decision-Making Skills
Češka, Ondřej ; Malik, Aamir Saeed (referee) ; Hussain, Yasir (advisor)
Cílem této práce je neinvazivní posouzení vybraných kognitivních domén (pozornost, paměť, rozhodování) pomocí nové mobilní aplikace vyvinuté za tímto účelem. Posuzování kognitivních nedostatků je důležité pro prevenci neurokognitivních poruch. Byly analyzovány existující posuzovací úlohy a na jejich základě byla navržena a úspěšně implementována kognitivní herní baterii sestávající ze 3 mobilních her. Aplikace je určena pro platformu Android a byla vyvinuta v Unity engine. Byl vytvořen systém pro sběr a uchovávání herních dat a jejich následné zhodnocení za pomoci cloudové dostupnosti. Jeho spolehlivost byla posouzena na základě vlastního sběru dat a poznatků existujících studií. Vyvinutá aplikace přináší jiný pohled na posuzování kognitivních nedostatků, porovnává uživatelem dosažené skóre s ostatními hráči a poskytuje mu detailní zpětnou vazbu.

Intelligent Access Terminal Using ESP32 Platform
Pomykal, Šimon ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to design cheap intelligent access control system based on esp32. This system is designed for use in family houses, flats, garages, gardens etc. The designed system is composed of access control terminal module which uses fingerprint reader to authenticate people and of camera modules which monitor the area of entry These modules are connected to cloud using AWS IoT Core. Another part of the system is a cloud application which evaluates data from the system. The acces control system is meant to be part of a home security system, but can be used independently to some extent.
