Security Analysis of Mifare Classic Smart Cards
Bobčík, Martin ; Hellebrandt, Lukáš (referee) ; Hujňák, Ondřej (advisor)
Goal of this bachelor thesis is a security study of MIFARE Classic contactless smart cards and risk analysis of their usage. There are described individual vunerabilities in the design and CRYPTO1 cipher of such cards. In this thesis is also experimented with Chameleon Mini device, which is used to perform two attacks and one cryptoanalysis of the cards. Namely, card emulation, relay attack, and analysis of insufficient randomness of cards' pseudorandom number generator. From those, only card emulation was fully successful.

Experimental and Numerical Analysis of the Volume Changes of Fine-grained Concretes
Odstrčil, Štěpán ; Frantík, Petr (referee) ; Kucharczyková, Barbara (advisor)
This diploma thesis deals with the experimental and numerical analysis of volume changes of fine-grained concrete. Experiments were carried out, measuring both the length changes as well as the mass losses and the internal temperature of the test specimens made from fine-grained concrete. The measurements were divided into two parts (phases). The first phase took approx. 72 hours. The second phase was focused on the long-term measurements and will be completed after stabilization of the mass losses and length changes. In the diploma thesis, the first phase of measurement was elaborated in detail, both in terms of experimental and numerical analysis. In addition, a C # .NET program was created to facilitate the processing of raw measurement data from the data logger. Finally, a comparative calculation was performed according to the model B4, where the result of the calculation was compared with the results of the experiment.

Antispam protection of web pages
Orsák, David ; Míča, Ivan (referee) ; Kacálek, Jan (advisor)
This thesis deals with questions of spam especially for web pages. The work specifies the term spam, history of spam and that individual division according to way diffusion and type sight. Here is decrypted questions legislature for spam and assessment consequences for this issue. With problem of spam is closely linked the botnets, which are main sources of spam, in this thesis is decrypted how botnet work and witch botnets are the biggest in this time that mean botnet which delivered the most of spam per day. The main part this work is to defined and decrypted different ways of spam protecting websites. Here are given type of protection from basic protection for hardy form protection, name CAPTCHA. In the practical part of the thesis offers some variants CAPTCHA, which could be reused for antispam protection for web pages

Implementation of Information System ANDI in Speech Therapy Practice
HOLAKOVSKÁ, Eva
This thesis focuses on development of the ANDI project, which aims to make it easier for speech therapists to manage information about their clients and therapies. The paper deals with the usability of the ANDI application software for wider groups of customers. This is followed by qualitative research, based on which subjects representing possible archetypes of potential future users are selected. Based on interviews with these specialists, a list of specific requirements is compiled, the implementation of those requirements then expands the functionality of the system and its practical usability. At the end of the paper, there is an evaluation from the author's point of view and an outline of the further possible development of the project, both in the implementation of the new version of ANDI 2.0 to several independent speech therapy practices, and also for the establishment of cooperation with the commercial project Logapka.

Development of an Application Suitable for Storing Results of Speech Therapy
HOLAKOVSKÁ, Eva
Thesis is focused on software development. The developed application is for speech therapist practise and its main function is storing information about clients and their therapies. The first part of the paper is about systems development life cycle and theoretical step by step approach for software development. The second part of the thesis speaks about development of an application called ANDI, which serves to speech therapists. This software is able to store data about clients and their sessions. Program can also be used for long-term observation of client progress. Data are insert through electronic forms and outputs are presented in multiple charts.

Identifikace železničních vozů na základě obrazové informace
ŠEPS, Pavel
This master's thesis focuses on the design and implementation of railway wagon indetification system based on the identifying information on the side of each wagon. It describes the search for the optimal image preprocessing, comparison of OCR services, search for the suitable technologies and evaluation of the quality of the finished application. Part of this thesis also describes existing solutions and the application development and functionality. To obtain the images of the wagons, a photo trap is designed and assembled, which is then located near the train track. A custom neural network was built to find the identifying information and a custom annotation application was developed to create the test and training sets. The final identification application then implements this neural network. It also uses Azure OCR services. It is designed to automate the manual process and is ready for use in real operation.
