Authentication using a mobile phone
Križan, Viliam ; Hajný, Jan (referee) ; Malina, Lukáš (advisor)
Bachelor’s thesis describes the basics of authentication methods by knowledge, used authentication tokens and biometric ways of authentication. It discusses the capabilities of the individual methods designed for mobile phones. It covers the basic security in the GSM network (using SIM cards) and usage of authentication based on passwords, PIN codes, gestures, facial recognition and speech recognition. Thesis evaluates individual methods in terms of success and performance. It discusses the usage possibilities of authentication methods on the Android platform, where it provides the options of modular arithmetic operations of cryptographic primitives. The work evaluates the time consumption of modular arithmetic operations on the mobile phones with created application. It also lists available algorithms of symmetric and asymmetric ciphers, one-way hashes on the Android platform. The section of authentication protocol conception writes about protocol based on zero-knowledge proof, which authenticates users anonymously. It also proposes the transfer of calculated authentication variables using NFC technology. The protocol also supports the revocation of malicious users. The goal of the thesis was to create two applications that have implemented the selected authentication protocol. The first application designed for users, runs on mobile phones with Android operating system. Application calculates the authentication variables using authentication parameter which it loads from secure element of the phone. After calculations it sends the authentication variables via NFC reader (connection phone – reader). NFC reader is connected to the second application, which verifies the user’s authentication variables and decides the conclusion of authentication. The last part of thesis is devoted to testing the developed applications and running them on the devices. It evaluates the security of the authentication protocol, usage of the phone’s secure element and a security of the transmission over NFC.

Modern technology in prehospital emergency care
BRŮŽKOVÁ, Nikola
This bachelor thesis deals with the topic of modern technologies in prehospital emergency care. The bachelor thesis is divided into theoretical and practical part. The theoretical part is focused on individual technologies, which are, according to available sources, considered modern. The set goal, which the bachelor thesis should fulfil, is to find out about applicability of modern technologies in prehospital emergency care. Two research questions were also established: which modern technologies are used in prehospital emergency care and what impact do modern technologies have on the providing of prehospital emergency care. To fulfil set goal, research study was conducted in a qualitative form via the semi-structured interview technique. These interviews were processed using open coding and after that, the analysed data were sorted into individual categories. The research sample consisted of paramedics of the South Bohemia region. The practical part of the bachelor thesis contains results of the research study, in which the answers to the previously mentioned research questions were found and in addition to that also the opinion on modern technologies in prehospital emergency care from the point of view of a paramedic. In the answers of the paramedics was found, among other things, that they all agree on the fact, that the app Záchranka benefits prehospital emergency care. On the contrary, a drone, as an unmanned aerial vehicle, does not have that much of a significance for the prehospital emergency care of the Czech Republic, actually exactly half of the respondents did not have any knowledge about this medium. It was also found, that, according to the respondents, modern technologies overall significantly influence prehospital emergency care, however the experience was not always a positive one. This bachelor thesis can be beneficial due to the processed information in the theoretical part and following results in the practical part.

Smartphones in education
Hruška, Ondřej ; Vaňková, Petra (advisor) ; Leipert, Jiří (referee)
Modern technology has become an integral part of our life but its implementation into school education is not so fast. Most of the population own a smartphone. While some people say that smartphones should be used in the lessons, others would prefer a partial or complete ban on them in schools. This work summarizes strengths and weaknesses of smartphones in education based on the literature review and discusses some recommendations on their use. Use of smartphones in education was studied in an application which helped with the basics of Russian alphabet. It was shown that most of the users did not read license terms, preferred their own gender for application voice and tended to leave the application prematurely. The users from primary and secondary schools seemed to prefer to use the application more at weekends than on working days, and the application was willingly installed more by older users. A questionnaire survey at a school was used to grasp the whole topic. It was revealed that that touch devices would be welcome in education by students, and they were prepared to use their own smartphone for studying, but at school rather than in their free time. Mobile phone is the preferred device for games playing and internet browsing, but the most used applications include social networks,...

The Influence of Modern Technologies on Cognitive Development of Children in Early School Age
URBÁNKOVÁ, Markéta
This bachelor thesis focuses on the influence of digital technologies on cognitive development of children in younger school age. I will focus on several cognitive functions and try to prove whether the frequent use of modern technologies affects their memory, attention, language competence or their intelligence, and whether there are any other problems associated with this overuse. I chose this topic because from my point of view i tis a hot issue. Modern technologies - mobile phones, tablet or game consoles have advanced a lot and almost every child actively uses these technologies on daily basis today. This topic is really controversial indeed, I view this issue rather negatively, that is why I chose this topic.
