The purpose of this project is to explore the GPU for general purpose computing. The GPU is a massively parallel computing device that has a high-throughput, exhibits high arithmetic intensity, has a large market presence, and with the increasing computation power being added to it each year through innovations, the GPU is a perfect candidate to complement the CPU in performing computations. The GPU follows the single instruction multiple data (SIMD) model for applying operations on its data. This model allows the GPU to be very useful for assisting the CPU in performing computations on data that is highly parallel in nature. The compute unified device architecture (CUDA) is a parallel computing and programming platform for NVIDIA GPUs. The main focus of this project is to show the power, speed, and performance of a CUDA-enabled GPU for digital video watermark insertion in the H.264 video compression domain. Digital video watermarking in general is a highly computationally intensive process that is strongly dependent on the video compression format in place. The H.264/MPEG-4 AVC video compression format has high compression efficiency at the expense of having high computational complexity and leaving little room for an imperceptible watermark to be inserted. Employing a human visual model to limit distortion and degradation of visual quality introduced by the watermark is a good choice for designing a video watermarking algorithm though this does introduce more computational complexity to the algorithm. Research is being conducted into how the CPU-GPU execution of the digital watermark application can boost the speed of the applications several times compared to running the application on a standalone CPU using NVIDIA visual profiler to optimize the application.

THE MONITORING EMPLOYEES AT WORK The thesis deals with the legal protection of privacy and property in connection with the employees monitoring. The legal practice solves this problematic area in a different ways, which makes this topic highly actual. The thesis is composed of six chapters, each of them describes important aspects of the employees monitoring. First two chapters are introductory and define basic terminology and legal principles related to the personal data protection. Chapter Three focuses on the privacy as a fundamental human right and points out the issue of the confrontation with other values. Possibilities to enforce the right of privacy are outlined in the last part of this chapter. Chapter Four examines relevant Czech legislation concerning employees monitoring and personal data protection in labor law relations. The means of employees monitoring are analyzed in Chapter Five, which is subdivided into five parts - camera surveillance systems, correspondence confidentiality, internet use, GPS localization and biometric identification and authentication. Chapter Six seeks to describe the relevant Czech case law and illustrates the approach to decision-making by the administrative authority. The thesis strives for the brief analysis of employees monitoring in terms of generally binding...

of the Thesis This thesis deals with a problem of surveillance in public spaces. In the introduction it was specifies that the main aim of the thesis is to give a complex view on the topic of surveillance cameras in public areas from the constitutional law perspective. In the Czech republic, no further discussion has developer and legislatively, the issue is only regulated by the personal data protection law. And this regulation is not even complex, it only deals with CCTV kind of cameras, excluding the ones without storing the data. In the beggining of the thesis I explai right to privacy and under which conditions it can be limited. The core of the paper deals with camera systems themselves, their use, pros, cons and effecitivity. Later I describe opinions of some offices and states on the topic. Proportionality test of the constitutional court and the ECHR to balance right to privacy with the state responsibility for public safety was conducted in the last part of the thesis. The advantage of CCTV is that thez provie impression of security to the citizens. They discourage potential perpetrators and help to maitain security of individuals, property and public interests, as well as detection, prevention and conviction of criminals. It helps securing proofs for future trials. On top of that, CCTV...

Magister Legum - LLM / Access to medicines is an essential component of the basic human right to health and a key determinant of the importance attached to the health care system of a country. It essentially entails the availability and acceptability of the essential medicines on the market and the ability of patients to afford such medicines when needed. Globally, countries face access to medicine challenges partly because of patents which undoubtedly accounts for excessive pricing of medicine. As such, efforts have been made to ensure the accessibility of medicines through the Trade-Related Aspect of Intellectual Property Rights (TRIPS) flexibilities of the World Trade Organisation (WTO). Beyond these interventions, it is incumbent on Members of the WTO to domesticate the flexibilities of the TRIPS Agreement before their utilisation because by their very nature, they cannot be self-executed. With an estimated population of 29.6 million, about 310 000 people in Ghana are living with HIV. The country’s health facilities record 40 per cent of outpatient visits each year and about 14 550 per 100 000 of the population are infected with tuberculosis with cancer on the rise. These diseases require medicines which are mostly patented yet Ghana has access to medicine problems despite the existence of a national health insurance system. Ghana has however not fully incorporated the TRIPS flexibilities in its national legislations and therefore unable to fully utilise the flexibilities as an option to access essential medicines. Questions therefore remain as to why and how Ghana can utilise the flexibilities to improve access to medicines. Based on an examination of the WTO’s patent system and legislations of Ghana, this mini- thesis contends that, the extent of incorporation of the flexibilities are inadequate due to the existence of lacunas in the Ghanaian legislations. Furthermore, a comparative assessment with South Africa supports an understanding that conditions are not ripe for full utilisation of all the flexibilities. It further argues that the utilisation of the TRIPS flexibilities by Ghana has been rendered ineffective due to administrative, political, economic and social challenges which adversely affects the full utilisation of the flexibilities incorporated and those yet to be incorporated. It is therefore important that Ghana adopts holistic approaches taking into consideration best practices if the TRIPS flexibilities must be effectively utilised. This mini-thesis concludes that, the TRIPS flexibilities are necessary for accessing essential medicines in Ghana to promote the right to health and that a review of Ghana’s current legislations to fully incorporate the TRIPS flexibilities and addressing other non-legal challenges are the required linchpin for effective utilisation of the TRIPS flexibilities.

A research report submitted to the Faculty of Arts, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Arts, Johannesburg, 2017 / This research investigates real names, pseudonyms, and anonymity online. From its small beginning as a research tool, the internet has grown radically and been increasingly incorporated into people’s daily lives. Simultaneously, as the internet has grown and changed, so have its uses, and perceptions of the naming practices used on it. Attitudes towards acceptable name use online have changed over time. Social networking sites have had a strong influence on name usage policies. This research examines how these attitudes have changed, and the implications of real names, pseudonyms and anonymity for behaviour on the internet and privacy. The radically disembodied nature of online communication lends itself to disinhibition, which in turn has resulted in online communications’ reputation for trolls and abusers. Contrary to the common assumption that the use of real names offline indicates the legitimacy of using real names online, online and offline communications are radically different. Online communications have very different considerations regarding privacy, identity theft, the digital footprint, and collapsed context, many of which are not present in offline communications. This paper examines naming policies and site structure through two case studies. The first case focuses on News24 and the Daily Maverick, both of which are South African news sites. Due to the need for rational and polite discourse, these implemented real name policies in order to enforce good behaviour amongst their users. In both cases, the real name policies failed. The second case study is that of 4chan, the American image board site. 4chan does not require any login process, and its users are typically anonymous. Despite being notorious for trolls, illegal content, and its image board /b/, the site’s architecture, along with the way that posts are created and then kept alive, mean that the site can be effective at moderating the kinds of content that it deems appropriate for each of its boards. Despite the contrasting nature and purposes of the news sites and 4chan, there are lessons to be learnt from the failure of real name policies, and the architecture and set up of sites which can be used to enforce particular behaviours. Furthermore, despite the ephemeral and shifting nature of 4chan, identity and a sense of belonging remain important to its users, hinting at the importance of a sense of identity to site members and the role of this identity in ensuring that users adhere to the norms. / XL2018

PERSONAL DATA PROTECTION IN LABOUR LAW RELATIONSHIP JUDr. Jakub Morávek The thesis is concerned with personnel data protection in connection with labour-law relationships. Personnel data protection issue is approached completely here and explanation of it is organically interconnected with cases of its use in labour-law relationships. Factually the thesis is output of grant-aided project GAUK No. 121009 "Personnel data protection in labour-law relationships" researcher of which the author was in the years 2009 - 2012.

The major theme of third and fourth subchapter is demarcation of Data Protection Officers position to the controller...

Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2018. / This study recognises that, regardless of information security policies, information about institutions continues to be leaked due to the lack of employee compliance. The problem is that information leakages have serious consequences for institutions, especially those that rely on information for its sustainability, functionality and competitiveness. As such, institutions ensure that information about their processes, activities and services are secured, which they do through enforcement and compliance of policies. The aim of this study is to explore the extent of non-compliance with information security policy in an institution. The study followed an interpretive, qualitative case study approach to understand the meaningful characteristics of the actual situations of security breaches in institutions. Qualitative data was collected from two universities, using semi-structured interviews, with 17 participants. Two departments were selected: Human Resources and the Administrative office. These two departments were selected based on the following criteria: they both play key roles within an institution, they maintain and improve the university’s policies, and both departments manage and keep confidential university information (Human Resources transects and keeps employees’ information, whilst the Administrative office manages students’ records). This study used structuration theory as a lens to view and interpret the data. The qualitative content analysis was used to analyse documentation, such as brochures and information obtained from the websites of the case study’s universities. The documentation was then further used to support the data from the interviews. The findings revealed some factors that influence non-compliance with regards to information security policy, such as a lack of leadership skills, favouritism, fraud, corruption, insufficiency of infrastructure, lack of security education and miscommunication. In the context of this study, these factors have severe consequences on an institution, such as the loss of the institution’s credibility or the institution’s closure. Recommendations for further study are also made available.

The paper starts on the construction of the right to privacy and its mutations in face of technological advances, especially on the information and communication technologies. With that it faces from the firsts formulations of the right to privacy, as a right to be let alone, until it?s most recent formulations, as a right of each individual to control its own private information. After that, it analyses the north-american personal data protection system, housed on the figure of right to privacy, as well as the European personal data protection system, based on laws of European Union level. This analysis suits so that both systems can be used as reference for the study of the thematic on the Brazilian legal system, observed the due alterations to fit this legal system. In the end, the present paper faces the thematic of personal data protection on the Brazilian legal system, focusing on the profiling, with consists in a personal data treatment tool that figures between the ones that offers the hirer risk. Recognizing the fundamental character of the right to personal data protection, including in the Brazilian juridical system, the paper demonstrates the importance of the observation of personal data protection principles ? as the transparency, the purpose and the consent ? on the utilization of profiling mechanisms. Only this way it?s possible to conform the treatment of personal data with the rights of the data subject. / O presente trabalho busca enfrentar a tem?tica do direito ? prote??o de dados pessoais no ?mbito do ordenamento jur?dico brasileiro, enfocando a figura do profiling. O trabalho inicia na constru??o do direito ? privacidade e nas suas muta??es em raz?o dos incrementos tecnol?gicos, notadamente no que toca ?s tecnologias da informa??o e da comunica??o. Com isso, ele enfrenta desde as primeiras formula??es do direito ? privacidade, enquanto um direito a ser deixado s?, at? suas formula??es mais recentes, enquanto um direito de cada indiv?duo controlar suas pr?prias informa??es privadas. Depois, ele analisa o sistema norte-americano de prote??o de dados pessoais, albergado pela figura do right to privacy, bem como o sistema europeu de prote??o de dados pessoais a partir das normativas em n?vel de Uni?o Europeia. Tal an?lise serve para que ambos os sistemas sirvam de amparo para o estudo do tema no ordenamento jur?dico brasileiro, observadas as devidas adequa??es para este sistema jur?dico. Por fim, o presente trabalho enfrenta a tem?tica da prote??o de dados pessoais no ordenamento jur?dico brasileiro sob o prisma do profiling, o qual consiste em uma ferramenta de tratamento de dados pessoais que figura entre as que ostentam o maior potencial lesivo. Reconhecendo o car?ter fundamental do direito ? prote??o de dados pessoais, inclusive no sistema jur?dico brasileiro, o trabalho evidencia a import?ncia da observ?ncia dos princ?pios da prote??o de dados pessoais ? como o da transpar?ncia, o da finalidade e o do consentimento ? na utiliza??o de mecanismos de profiling. Somente assim ? poss?vel conciliar o tratamento de dados pessoais com o respeito aos direitos do titular dos dados.
