Digital Text Steganography
Nodžák, Petr ; Nevoral, Jan (referee) ; Strnadel, Josef (advisor)
The goal of this bachelor project was to learn about digital text steganography, about methods for hiding the text, to implement my own or already existing methods and finally to compare acomplished results of these methods. This project introduces four methods (Zero distribution, semathics, syntax and Format based) which hide secret data into cover text, each of them by its own way. Research has found that semanthics method produces the best properties of stego text followed by Format based and Zero distribution, syntax method ended up worst. Based on the data found we can choose which method we will use.

Regular Expression Based Searching in Text Files
Šimek, Ota ; Samek, Jan (referee) ; Rozman, Jaroslav (advisor)
This paper desribes the design, analysis and implementation of the program, whichis used to search for specific parts of text in text and xml files. To search, you must create a template using two text-matching technigues. These are the regular expressions and XPath expressions. This is desribed in the first chapter. Application allows to process large number of files or files with a high content.
