Brna, Filip ; Homoliak, Ivan (referee) ; Tamaškovič, Marek (advisor)
This thesis aims to analyze the security and usability of cryptocurrency wallets of different categories. The work is focused on familiarizing with the most used cryptocurrency wallets, threats related to their use, subsequent testing of the selected wallets with the proposed test scenarios, and evaluation of the testing supplemented with the definition of several recommendations for their proper use. In the systematic testing, the method of designing test scenarios was used, followed by systematic testing, and finally, the results were evaluated. The research conducted found that the most widely used cryptocurrency wallets achieve a high level of security against the described threats and offer a wide range of possibilities for their use. The results of this work allow users to understand the issues associated with storing and handling cryptocurrencies more efficiently. Based on the results of the testing, the user has the possibility to choose a cryptocurrency wallet precisely according to his user's needs and security requirements.

Relevance of Usable Security Guidelines from IT Professional Point of View
Galanská, Katarína ; Polčák, Libor (referee) ; Malinka, Kamil (advisor)
Vyvážení bezpečnosti a použitelnosti bylo vždy výzvou. Navzdory důležitosti zabezpečení softwaru jsou bezpečnostní pokyny a standardy často příliš komplikované, náchylné k chybám nebo časově náročné. Tato nerovnováha iniciovala vznik pojmu použitelné bezpečnosti. Po celá léta to byl běžný výzkumný problém. Zatímco softvér by měl být vyvíjen s ohledem na použitelnost koncových uživatelů, bezpečnostním standardům a směrnicím, které používají IT profesionálové, není z hlediska použitelnosti často věnována dostatečná pozornost. Vzhledem k tomu, že se od odborníků v oblasti IT očekává vyšší úroveň znalostí, často čelí velmi složitým oblastem, když se snaží vyhovět konkrétním bezpečnostním standardům nebo dodržovat konkrétní pokyny. Tato práce představuje studium současného povědomí v oblasti použitelné bezpečnosti. Práce sestává z provedeného průzkumu, analýzy stávajících použitelných bezpečnostních pokynů a navrhuje vzdělávací pomůcku k řešení problémů, které výzkum přinesl. Hodnocení vzdělávací pomůcky ukázalo pozitivní dopad na povědomí IT odborníků.

Loginova, Natalya ; Rudnitckaia, Julia (referee) ; Hruška, Tomáš (advisor)
Tato práce je věnována studiu některých aspektů použitelnosti vizualizace dat v informačních dashboardech. Cílem této práce je navrhnout model popisující vybrané druhy dat, které jsou nejčastěji používané v informačních dashboardech, a jejich možné grafické reprezentace, a poté implementovat nástroj na automatické generování vizualizací dat podle navrženého modelu. Nástroj mohou využít výzkumníci zabývající se zkoumáním různých aspektů grafické reprezentace dat k provedení uživatelských testů. Ukázkový průzkum uživatelů byl rovněž proveden v rámci tohoto projektu.

Web Interface for Human Corrections of Automatic Transcript and Tagging
Plhal, Jan ; Hradiš, Michal (referee) ; Szőke, Igor (advisor)
The goal of this thesis is the design and implementation of a web application for human corrections of automatic transcript and annotation of VHF (very high frequency) pilot-tower radio communication. The main inspiration is the ATCO2 SpokenData annotation service from the company ReplayWell, which was remade from the ground up into a more user-friendly form with a number of user customizable elements. Based on studied principles of designing a well usable user interface and insights gained from research of annotation applications was created a functional design and also a graphical design of the application in the form of a wireframe. The designed application was successfully implemented using the selected technologies. The usability of the application was verified and improved with the help of user testing and the application was also deployed on the SpokenData website.
