Design of an electronic document management system
Mlčáková, Kristýna ; Míšek, Jakub (referee) ; Loutocký, Pavel (advisor)
Bachelor's thesis deals with the problematics of the electronic documents, especially in the area of their archiving. The thesis consists of two parts - theoretical and practical. The analysis of the electronic document position in the Czech legal environment is a significant and essential part of the thesis. The analysis is included in the theoretical part of the thesis. Based on the theoretical knowledge, we created an application for the electronic document management system, which is the subject of the practical part of the bachelor's thesis. The application itself represents a repository in the accordance with § 562 paragraph 2 of the Civil Code.

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.

Possibilities of archiving NC programs in small versus large companies
Mikulec, Jan ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with archiving of NC programmes in engineering companies. The theoretical part describes how the machine tools and their archiving tools are developed. Then the NC programme is characterised together with its structure and the importance of individual characters, followed by characterisation of currently used archiving tools and description of NC programmes labelling that simplifies the archiving. The last part is dedicated to practical examples of the NC programmes archiving and their comparison. The thesis is supplemented with examples of archiving programmes used in chosen companies.

Secure data archiving using cloud computing
Šulič, Martin ; Sikora, Marek (referee) ; Člupek, Vlastimil (advisor)
This master’s thesis is focused on detailed analysis of possibilities of implementing a private cloud and secure data archiving for a long period of time using open-source tools. It describes the individual standards and processes of data preparation, as well as the OAIS reference model for long-term preservation. From the analyzed information, a complete design of the final solution is created, with a description of the functionality and the method of deployment in the environment of Docker containers. The design implementation and the main functionality of individual systems such as Archivematica or Nextcloud are thoroughly described and also the hardware requirements and cryptographic security were evaluated.

Multimedia Grid
Šimko, Viliam
The thesis describes the possibilities and issues of existing videoconferencing systems. We focus on open-source solutions for group-to-group communication especially the AccessGrid technology that utilizes the multicast packet delivery method of multimedia content. We describe AccessGrid node created for CIANT organization, which has been taken as a starting point for defining the architecture of a videoconferencing system based exclusively on open-source components, particularly Linux and related software. We address issues related to firewalls and NAT traversal and provide a comparison of various videoconference-related codecs and protocols. Finally, the text touches the question of recording and archiving of conference sessions and provides a new integrated recording application -- StreamVNC. The tool allows users to prepare their presentations using localhost recording facility which includes AGVCR for recoding RTP packets, EVIC for grabbing the VNC display and camera source and RAT as an audio encoder.

The Integration of ETDs into the University Repository of the TUL
Vencláková, Jitka ; Trykarová, Markéta
The paper maps the entire process of building and commissioning the digital repository of the Technical University of Liberec. It also briefly discusses the preparation phase, and primary options for storing and accessing theses and publications. The whole process of assembling the repository has been seen from a direct participant’s point of view. This contribution is a summary of practical experience and examples of good practice, and moreover, points out the demonstration of failed processes. In addition, the contribution includes a description of the current state of active repository processes and a brief proposal for its further development and improvement

Archiving of news and sport footage in the Czech TV
Ondrejčík, Gustav ; Záruba, Robert (advisor) ; Kruml, Milan (referee)
This thesis describes the process of archiving of shots and programmes in news and sport editorial offices of the Czech Television. Newsroom prepares broadcasts for ČT1 and ČT24 programmes. The sport editorial office provides the broadcasts for ČT SPORT and also prepares the news for "Branky, body, vteřiny" on ČT1. With regard to this, both offices produce a considerable amount of audio-visual material. The thesis examines how this material is subsequently archived. Do both offices have a systematic and comprehensive procedure for archiving of shots and programmes? And are these archives easily traceable, available and usable for further broadcasting? The thesis summarizes the history of archiving of news and sport audio-visual material. The key process of digitization, which allows the transcription and saving of old archive materials stored on tape media, is also mentioned. After describing the history of archiving, the author focuses on the current methodology of the process and describes the system of archiving in news and sports news. Who does archiving and what systems and programmes are used for it? At the end of this thesis the future of archiving is analysed with regard to the progress in technologies used for archiving.

The Reflection of Literary Activities in Digital Space
Hartmanová, Pavla ; Czwordon-Lis, P.
The Czech Literary Bibliography comprises a set of bibliographical records which reflect cultural journalism and specialist texts on Czech literature. The aim of the contribution is the introduction to a new project of the Institute of Czech Literature: The Czech Literary Internet. The project has extended our sources to excerpt platforms, web pages and electronic magazines whose content is not easily searchable through classic search engines. It turns out that this resource illustrates the professional debate on literary events and development and,\nin particular, brings new information on culture in regions and popular literature.
