Authenticity and Digital Information
Cubr, Ladislav ; Ivánek, Jiří (advisor) ; Sklenák, Vilém (referee) ; Hutař, Jan (referee)
The dissertation focuses on the authenticity of digitized books in the context of their life cycle (production, preservation, access). First the OIAS high-level conceptual framework for lifecycle management of digital documents maintained by organizations is introduced. Then the current situation of digitized books lifecycle management is described. This part is followed by an introducing to relevant conceptualizations of the authenticity of digital documents and these conceptualizations are analyzed and reviewed. Then framework for analysis of authenticity is established based on previous findings. This framework is then used to identify authenticity requirements for digitized books and to develop a domain-specific conceptualization of the authenticity of digitized books. This conceptualization deploys detailed analysis of risks threatening authenticity during lifecycle management of digitized books. The selected topics of this conceptualization are then the source for the next step, which is to develop a recommended practice for maintaining authenticity of digitized books. This practice is further specified for one partial solution to the problem of maintaining the authenticity of digital documents throughout their life cycle, which is a persistent identification system.

Traffic detection and analysis using SSL/TLS
Hutar, Jan ; Dvořák, Jan (referee) ; Smékal, David (advisor)
This diploma thesis deals with a detection and analysis of secure connections of electro- nic communication through SSL/TLS protocols. The thesis begins with introduction to SSL/TLS protocols. Thereafter, an analysis of messages used to establish secure con- nections using STARTTLS and postal protocols SMTP, POP3, and IMAP was made. Metadata detection and extraction of secured simplex and duplex connections take place using deep packet inspection tools. The tool of choice is the nDPI library from the Ntop project. The library was extended to detect the connections and extract the metadata based on studies and analysis of transmitted messages. Finally, testing is performed on a training data set and a basic analysis of acquired metadata is made.

Technical metadata for still images
Twrdý, Přemysl ; Bratková, Eva (advisor) ; Hutař, Jan (referee)
This bachelor thesis presents still images from technical metadata point of view, which are used nowadays to communicate images. The NISO standard ANSI/NISO Z39.87 from 2006 (MIX) is presented in detail. Commented examples of metadata records in XML structure show practical use in digital information systems. Finally, in the Conclusion all gathered information is summarized and prospects of using this standard in the Czech Republic are outlined.

Digitalization, metadata description and metadata formats
Hutař, Jan ; Kalkus, Stanislav (advisor) ; Bratková, Eva (referee) ; Sklenák, Vilém (referee)
(EN) This thesis is dedicated to the processes of digitization and metadata description, as well as the links that connect them. In recent years, another topic has been becoming relevant for both mentioned processes - the logical long-term preservation of digital objects. Long-term preservation is dependent on metadata and therefore on the processes of digitization, when some important metadata is created. The first introductory chapter of the thesis briefly describes, with an emphasis on metadata, digitization and theoretical and practical problems of long-term preservation of digital objects. The OAIS reference framework is also analysed, since it is the background for digital preservation and present preservation metadata standards. OAIS is also important for the shape and functionality of digital repositories. Metadata is also the topic of the next chapter of the thesis. General metadata use and its development are discussed, with emphasis on administrative, technical and preservation metadata. The following chapter focuses on the use of metadata in the National Library of the Czech Republic. It describes the evolution during two periods leading up to the present. This section includes comments on how long-term preservation has been reflected in used metadata standards. The second-to-last part...
