Sports Manager for iOS
Hort, Jaroslav ; Smrčka, Aleš (referee) ; Hrubý, Martin (advisor)
This work discusses design, implementation, connection, testing and practical use of mobile application for iOS and supporting web application. I have analyzed the effects of music to sport and designed and implemented a fitting mobile application allowing users to collect data from their activities, music players and see the effects of music on them. During design and implementation, I have emphasised usability, expandability and synchronization with cloud storage, for this reason I have created a web application, allowing users to monitor their results captured from mobile anywhere.

Cloud Storage Integration into Web Applications
Studnička, Ondřej ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
The aim of this thesis is to analyze selected cloud storages and their APIs. The practical use is demonstrated in web application that is used for to create dynamic presentation based on Reveal.js framework. The application allows user to save the created presentation to selected cloud storage. Supported storages are Google Drive, Dropbox, Github and Gitlab. The application is implemented using Vue.js. The theoretical part of the thesis focuses on the possibilities of creating web applications according to current trends. The practical part describes the implementation and testing of the created application.

Advanced Filtering of Digital Evidence
Chudáček, Ondřej ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
This thesis focuses on the implementation of advanced filtering of digital evidence stored on an open source cloud storage NextCloud. The contents of the thesis are law analysis regarding the storage of digital evidence in NextCloud, design of NextCloud, homomorphic encryption and its possible usages, attribute based searchable encryption and its usages and implementation of a simple stand-alone filtration client. Experts on digital evidence were asked about the choice of filtration criteria as a part of the thesis. The key feature of the thesis is a description of implementation of filtration inside NextCloud which has been extended to contain five new filtration criteria. The result has been submitted to performance and functional tests.

Framework for a Web Internet Service Implemented in Google Cloud Platform
Roshka, Andrei ; Smrčka, Aleš (referee) ; Hrubý, Martin (advisor)
Cílem této bakalářské práce je navrhnout a naimplementovat rámcové řešení pro placenou internetovou službu a nasadit ho na cloudové služby poskytované Google Cloud Platform s nejnižší provozní cenou. Výsledná architektura je serverless a používá služby Firebase jako Firestore NoSQL databáze, Firebase Storage a Firebase Authentication. Rešení je psáno v jazyce TypeScript a skládá se ze dvou hlavních cásti - front-end aplikace a pracovního procesu, který zpracovává výpočetní úlohy. React se používá k vytvoření uživatelského rozhraní založeného na komponentách spolu s Reduxem pro centralizovanou správu stavu aplikací. Jako server pro front-end se používá Nginx. Pracovní proces je postaven na Node.js - serverovém prostredí pro JavaScript. Aplikace je úspešně nasazena do servisy Cloud Run jako sada Docker kontejneru za použitím CI/CD pipeliny postavené na Cloud Build.

Cloud-Based Data Access Control
Chovanec, Erik ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
This thesis is dealing with problematic of cloud storage. The goal of this thesis is the implementation of cloud storage, that will be able to provide the required functionality. These functionalities are access control of multiple users, group rights, long-term file archiving, secure data transmission to cloud storage, protection of data integrity and confidentiality during transmission and storage. For achieving this goal, there is an evaluation of suitability using public cloud providers. Based on this evaluation, there was a conclusion, that these services are not suitable for storing highly sensitive data. Next is an evaluation of advantages associated with using software that is licensed under a free or open-source software license. Even though there are high start-up costs on infrastructure and there is a necessity to make a huge effort to run custom infrastructure with cloud storage, it is a much better option. Especially if it will be used for storing sensitive data. The following chapter describes an extensive analysis of existing open-source and free-software solutions. In the final part of this chapter, the application Nextcloud has been selected since it provides the most of required functionalities. The thesis also contains an installation of Nextcloud and shows its main functions. There are basic load tests, which are telling us about the efficiency of successfully dealing with parallel requests. In the last section of this thesis, we are dealing with the implementation of missing functionality in Nextcloud. This functionality is necessary to achieve our goal, which is long term archiving of files. This term means functionality that will enable the possibility to archive files with evidence about preservation integrity and confidentiality of archived files during a long period of their existence. This part of the thesis contains a theoretical design that aims to accomplish this goal. Description of the implementation follows after theoretical design. This functionality is implemented in form of a dedicated system. Archiving of files is triggered by a modified application, used in the Nextcloud server. This process will create a copy of the file to be archived on a separate hard drive. It will obtain evidence about integrity when storing the file and it will strengthen this evidence by obtaining a new one in regular periods. This happens on yearly basis. The quality of cryptographic protocols can degrade after a long period. This concept is trying to prevent this phenomenon.

Ensuring Long-term Data Integrity in Cloud Storage
Nohava, Martin ; Člupek, Vlastimil (referee) ; Malina, Lukáš (advisor)
The subject of the thesis is the design and development of a system to ensure the long-term integrity of data from the Nextcloud cloud storage, which manages and stores electronic evidence. In the introductory part, the terms and principles used for securing data integrity are presented, including quantum-resistant digital signature schemes. Subsequently, the architecture of the archiving system and the method of its connection with the Nextcloud cloud storage are proposed. The resulting system consists of two main components, the Archive application, which extends the web interface of the Nextcloud instance, and the archiving system, which ensures the integrity of the archived files themselves. In addition to time stamps, system also uses a quantum-resistant Dilithium signature scheme. At the end of the work, an evaluation of the implemented solution is carried out by measuring the performance of the archiving system, and options for its further development are proposed.

Cloud Service Access Control using Smart Cards
Muzikant, Petr ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
Využití osobních čipových karet pro autentizaci do webových služeb – jako je cloudové úložiště – není triviální kvůli nedostatku open-source implementací, standardizací a dokumentace. Tato práce zkoumá možnosti takové operace a nabízí řešení založené na estonské sadě nástrojů Web-eID. Hlavním účelem tohoto projektu je umožnit komunikaci státem vydávaných elektronických průkazů totožnosti s webovými službami, ale díky své rozšiřitelnosti a open-source licenci je vhodný i pro obecné webové aplikace a vlastní, personalizované čipové karty. Výstupem této diplomové práce je rozšíření projektu v podobě velmi žádané nové knihovny pro validaci autentizačních tokenů pro jazyk PHP, dále instalovatelná Nextcloud aplikace umožňující dvoufaktorovou autentizaci s Web-eID, a také nový JavaCard applet, plně kompatibilní s Web-eID. V práci jsou rovněž prezentovány výsledky implementace s vyvinutým open-source JavaCard appletem a vyhodnocení potenciálu využití českých elektronických občanských průkazů se systémem Web-eID pro snadnější a rychlejší nasazení v budoucnu. Dodatečným cílem práce je také výpomoc vývojářům implementovat tuto silnou autentizační metodu do jejich webových aplikačních služeb, aniž by museli být odkázáni na státní, proprietární či nemoderní řešení.
