Security Risks of Mobile Device Sensors
Henclová, Kateřina ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
Tato práce představuje hrozby pro mobilní bezpečnost a soukromí, které představují mobilní senzory. Představuje rozhraní Generic Sensor API, mobilní senzory a způsoby jejich zneužití. Pomocí mobilních senzorů, jako je akcelerometr, gyroskop a magnetometr, tato práce demonstruje takový útok na mobilní senzory v prohlížeči. Zvoleným útokem je rozpoznávání aktivity, které provádí predikci aktivit pomocí strojového učení se slibnými výsledky a předpovídá správnou třídu aktivit přibližně v 69% případů napříč všech tříd. Pozornost je věnována také rozšíření JShelter a tomu, zda poskytuje ochranu před nežádoucím odhalením senzorů.

Koprivnice 3.0 - Housing A++
Bitarová, Ivana ; Vlček, Zuzana (referee) ; Nový, Vítězslav (advisor)
The master's thesis is a proposal for an urban-architectural study on the territory of the former handball court in Kopřivnica. The work is a continuation of the pre-master's thesis, in which I searched for and investigated the ideal form of housing in Kopřivnice. Corporate housing is a response to the problem of unaffordable housing and socio-economic conditions in the city. The search for the ideal of corporate housing resulted in the concept of low intensive development with the creation of spaces between buildings, flowing from public, through semi-public and semi-private to private. This idea creates spaces for spending time within the community and spaces for relaxation surrounded by edible plants. The proposal emphasizes the positive impact of housing on landowners. The transition from a busier environment to a more intimate one is also reflected in the design of the gallery 's apartment building, where the gallery is the place of frequent interaction with the neighbors. Private exterior space is represented by loggias equipped with sliding shading panels. In addition to shade and privacy, perforated panels also create the effect of a living facade, as their position changes depending on the time of day or season. The design of the apartment building is designed as a modular prefabricated construction. In the study, I present 14 modular apartments, from which the investor can construct an apartment building according to his own requirements.

Perception of patient privacy
HOFREITEROVÁ, Anna
The bachelor's thesis dealt with the issue of patient privacy in hospital facilities. The aim of this work was to find out how patients hospitalized in the inpatient ward perceive privacy, how nurses perceived patient privacy and in what ways nurses ensured the privacy of patients in the inpatient ward. Three research questions were set to investigate how patients hospitalized in an inpatient ward perceive privacy. Furthermore, they focused on the nurses' view of the perception of patient privacy and the ways in which nurses ensure the privacy of patients hospitalized in the inpatient ward. In the theoretical part, the work defines basic terms related to patient privacy, such as the duty of confidentiality, providing information with the patient's consent, providing information without the patient's consent, patients' rights, medical documentation, human needs and ensuring the privacy of patients during selected nursing procedures. In order to achieve the goal, the qualitative research method, the interview method and the semi-structured interview technique were used for patients hospitalized in the internal inpatient ward and for the nurses caring for these patients, as well as for patients hospitalized in the surgical inpatient ward and for the nurses caring for these patients. The research sample consisted of 6 patients and 5 nurses. The results of the obtained data led to the finding that the nurses had adequate knowledge regarding the issue of dealing with sensitive patient information. Nurses had adequate knowledge of procedures to protect patient privacy, although not all nurses used these procedures in practice. The research investigation further revealed that patients hospitalized in inpatient wards often did not think about their own privacy in the hospital environment, and the issue of privacy was a problematic and difficult topic for them to talk about. If the management of the investigated hospital is interested in the results of the investigation, they will be provided with them.

Need of intimacy of patients women 65+
NOVÁKOVÁ, Pavlína
The aim of this bachelor's thesis was to determine the status of the needs for intimacy and privacy of elderly women aged 65+ in a nursing home. Elderly women lose part of their privacy by entering such a facility. According to their degree of dependence on care, their intimate zone is violated during nursing care. I used the method of non-standardized interviews and direct covert participant observation to find out how the elderly women feel and cope in such situations. I collected data from 10 female clients and 4 members of the nursing staff of the Stachy-Kusov Nursing Home. The group of female clients was deliberately selected to represent seniors of different levels of self-care, mobility and care dependency. All nursing professions were represented among the staff. In the interviews, I explored how the clients felt in situations where they had to surrender some of their privacy and intimacy, how they coped with these feelings, and asked about their willingness and ability to communicate these topics. I investigated how nursing staff perceived these facts, their ability to empathize and communicate non-verbally with the elderly women in their care. From the data obtained, I drew conclusions regarding the saturation of the seniors' need for intimacy. It shows that individual approach with kindness and consideration is important to improve the feelings of care recipients. It is always necessary to act in the interest of preserving the dignity of the clients, to leave them the right to make decisions for themselves, not to reduce their capacity for self-care and to offer the possibility of relaxation through positive experiences or activities. In my research, the insufficient number of direct care workers to meet the individual needs of clients and the related lack of time that can be devoted to each client proved to be the limiting factor.

Facial Recognition in Video and its Applications in Law Enforcement
Fabián, Jan ; Šťastná, Dagmar (referee) ; Šedrlová, Magdalena (advisor)
This bachelor thesis aims to describe the facial recognition technology and its use in practice. In recent years, facial recognition technology became a heavily discussed topic, whether in connection with the deployment of this technology in China or due to its general potential for law enforcement. Facial recognition technology is a perfect example of a two-sided coin, as it brings many new possibilities of crime prevention etc. but also has the risk of being used to invade personal privacy. This thesis is based on a literature survey of some of the available resources dealing with this topic. It focuses on the history of this technology, methods used by facial recognition and mentions some examples of the use of video-based facial recognition in practice along with the social risks of the application of this technology.

Security and Privacy in IoT
Utěkal, Josef ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
The bachelor's thesis deals with the topic of security and privacy in the field of Internet of Things (IoT), for which resource constrained devices are typical. It is very important to find a suitable operating system that, in addition to low computational requirements, would also offer the desired functionality for these constrained IoT devices, such as real-time capabilities. OS RIOT seems to be the one for IoT. It enables you to run applications written in C language on any supported hardware -- in this bachelor's thesis specifically on Arduino Uno and Arduino Due. The thesis also describes several cryptographic libraries that are supported by OS RIOT. The aim is to implement selected cryptographic libraries and measure their computational and memory requirements on both Arduino devices. This is preceded by a theoretical and practical familiarization with OS RIOT, which is realized by creating the first project, and measuring the computational complexity of each cryptographic function of the WolfSSL library on the Raspberry Pi 4 Model B.

The Grid
Gajdošík, Andreas ; Magid, Václav (referee) ; Krekovič, Slavomír (advisor)
Work aims at consequences of fully developed infrastructure of web 2.0 and its wide social acceptance, which with cheap computing power leads to massive data interpretation. In relation to that this work uses public Facebook's data about user activity at right wing oriented Facebook pages which gathers and statisticaly analyzes. Result is then showed at web page which is designed to look close to the look of extreme right wing webs. Positive first sight impression of right wing sympathizers is then eroded with not so good empirical statistics. Under 100 users are commenting quite often so this right wing craziness looks like a small movement in the end. Therefore Grid stands somewhere between amateur sociol research and artistic intervention into public media space.
