Video game developers have implemented multiple measures to combat piracy throughout history. One of these measures, defined in this study as in-game anti-piracy measures, prevents player progression on unauthorized copies by degrading gameplay or drastically increasing the difficulty.This study conducts a content analysis research on textual data gathered from the world wide web to assess the public perception in regards to this type of anti-piracy measures. The data gathered for this study consists of 425 statements in the form of comments and forum posts that have been coded, divided into themes and then analyzed inductively to generate findings that can be linked to Moshirnia’s (2012) previous research.Even though no clear results occurred that can confirm Moshirnia’s (2012) findings, this study has discovered a potential connection between in-game anti-piracy measures promoting piracy. The findings also suggest that the unique “broke features” might lead to the popularization of games modded to let legitimate users experience them too.

Research regarding e-book management at academic libraries is scarce, especially referring to Swedish university libraries. The work with e-books regarding selection, acquisition, promotion etc. can give insight into the stance towards e-books and their use at Swedish academic libraries. Challenges and problems such as accessibility, licensing as well as DRM restrictions may hinder e-books from becoming worthy complements to printed books. This thesis gives more insight into the acquisition, work and distribution and general working processes with e-books at Swedish academic libraries. A total of eight Swedish university libraries with 13 representatives agreed to participate in semi-structured interviews. The main results are that selection and acquisition of e-books are both influenced by librarians themselves and by user demand, and that e-books are frequently used and sometimes even favored over print books. Complex licensing and DRM restrictions may lead to e-books not being fully appreciated, which is further complicated due to a lack of promotion of e-books by academic libraries. Academic e-books are offered in English due to a lack of Swedish titles. In some situations, print books are acquired, e.g. if electronic titles are not available or too expensive. Both formats have advantages and disadvantages regarding access, availability, usage and preference. While print books are cheaper and offer a tactile experience, e-books can be read by multiple users simultaneously and do not require storage space in contrast to print books.

<div>In a potentially hostile networked environment, a large diversity of security mechanisms with varying degree of sophistication are being deployed to protect valuable computer systems and digital assets. </div><div><br></div><div>While many competing implementations of similar security mechanisms are available in the current software development landscape, the robustness and reliability of such implementations are often overlooked, resulting in exploitable flaws in system deployments. In this dissertation, we systematically evaluate implementations of security mechanisms that are deployed in the wild. First, we examine how content distribution applications on the Android platform control access to their multimedia contents. With respect to a well-defined hierarchy of adversarial capabilities and attack surfaces, we find that many content distribution applications, including that of some world-renowned publications and streaming services, are vulnerable to content extraction due to the use of unjustified assumptions in their security mechanism designs and implementations. Second, we investigate the validation logic of X.509 certificate chains as implemented in various open-source TLS libraries. X.509 certificates are widely used in TLS as a means to achieve authentication. A validation logic that is overly restrictive could lead to the loss of legitimate services, while an overly permissive implementation could open door to impersonation attacks. Instead of manual analysis and unguided fuzzing, we propose a principled approach that leverages symbolic execution to achieve better coverage and uncover logical flaws that are buried deep in the code. We find that many TLS libraries deviate from the specification. Finally, we study the verification of RSA signatures, as specified in the PKCS#1 v1.5 standard, which is widely used in many security-critical network protocols. We propose an approach to automatically generate meaningful concolic test cases for this particular problem, and design and implement a provenance tracking mechanism to assist root-cause analysis in general. Our investigation revealed that several crypto and IPSec implementations are susceptible to new variants of the Bleichenbacher low-exponent signature forgery.</div>

本研究是探討如何運用語意網規則語言(Semantic Web Rule Language, SWRL)來表示網路上的數位版權管理(DRM)。以XML為主的版權表達語言(Rights Expression Language, REL)因為無法處理具有語意內涵層級的版權管理規則，所以在概念表達和處理能力上有所限制。因此，我們運用了結合本體論(Ontology)和規則(Rule)語言的SWRL來探討比較現有XML為主的版權表達語言的不足，並以實作驗證本體論和規則結合所具有語意特性，讓使用者能在網路上加以應用數位內容。 / In this research, we show how to use Semantic Web Rule language (Semantic Web Rule Language, SWRL) for the digit rights management (DRM) on the Web. Since XML-based Rights Expression Languages (REL) can not deal with the right management policies at the semantic level, their expression abilities for concept descriptions are limited. Therefore, we use SWLR to contrast the insufficiencies in existing XML-based RELs. In summary, we take advantage of semantic-supported REL for DRM systems on the Web.

El principal objetivo de éste proyecto de investigación es la definición de una arquitectura que permita la protección y gestión de los derechos digitales en un entorno de gestión de contenido multimedia, siguiendo estándares abiertos siempre que sea posible. A fin de conseguir dicho objetivo, se analizarán y considerarán múltiples estándares e iniciativas relacionados.En primer lugar se aborda la definición de una arquitectura preliminar basada en MPEG-21 que permite la protección y gestión de los derechos digitales (DRM) aplicables a contenido multimedia. Más adelante, se presenta una arquitectura genérica y se describen diferentes implementaciones desarrolladas en proyectos nacionales y europeos, como AXMEDIS, VISNET II, Linked-Work y GILDDA. El análisis incluye casos de uso, aspectos de seguridad y la propuesta de una metodología de prueba o test. En el caso de Linked-Work, se detalla una implementación específica, resaltando los conceptos clave que la hacen diferente de otros sistemas de DRM. / The main goal of this research project is to define a generic architecture for the protection and management of digital rights in a multimedia content management scenario following open standards as much as possible. In order to achieve this goal, several standards and initiatives will be analysed and taken into account.First, a MPEG-21-based preliminary architecture for the protection and management of digital rights for multimedia content is tackled. Later on, a more general architecture is defined. Several implementations are described such as those in several Spanish and European projects such as AXMEDIS, VISNET II, Linked-Work and GILDDA. The focus in made on use cases, security features and a testing methodology. Linked-Work details a specific implementation, emphasising on the key concepts that make it different from other kind of DRM systems.

Como forma de combater a pirataria na rede, os ebooks são protegidos por digital rights management (DRM), uma trava tecnológica que permite que os titulares de direitos autorais protejam seus direitos por meio do controle do que os usuários conseguem fazer com os arquivos digitais. O DRM pode determinar variáveis como em quais circunstâncias, quantas vezes, por quanto tempo e em quais plataformas o um arquivo pode ser acessado. Essa trava, por sua vez, é protegida por leis anticircunvenção que proíbem que os usuários a alterem ou a removam. Em regra, essas leis não exigem que a arquitetura dos sistemas de DRM observe os mesmos limites e exceções impostos ao direito autoral. Por conta disso, é possível que os sistemas de DRM estabeleçam novas regras para o uso de trabalhos artísticos, que ultrapassam a proteção conferida pelas leis de propriedade intelectual. No mercado de livros digitais, tais regras têm um impacto particular na concorrência. Uma vez que as livrarias usam diferentes sistemas proprietários de DRM em seus livros digitais, compatíveis com um número limitado de dispositivos de leitura, o leitor enfrenta problemas de interoperabilidade para adquirir e-books em uma loja diferente daquela em que seu dispositivo de leitura foi comprado. Essa baixa interoperabilidade vincula os leitores a um determinado ecossistema e aumenta os efeitos de rede, custos de mudança e barreiras à entrada nesse mercado, propiciando a concentração. Como resultado, as livrarias são capazes de exercer um grande poder sobre o fluxo de informações nesse mercado, minando o potencial dos e-books para difundir o conhecimento e promover a leitura. Assim, esta pesquisa examina como os sistemas de DRM e as normas anticircunvenção afetam a concorrência no mercado de livros digitais e como essa dinâmica concorrencial, por sua vez, impacta no acesso aos livros. A análise inicia-se com a descrição do mercado de livros digitais e avança à discussão teórica, consistente na revisão da literatura especializada sobre direito autoral, direito da concorrência e acesso ao conhecimento. Sob uma perspectiva de desenvolvimento como liberdade, conclui-se que a revisão das leis anticircunvenção é essencial para fomentar a concorrência nesse mercado, garantir a autonomia dos indivíduos e concretizar o potencial dos e-books para a expansão do acesso ao conhecimento. / Digital books facilitate access to books, through factors such as the reduction of geographical and financial barriers, serving as an important instrument for promoting access to knowledge in the XXI century. To prevent works from being pirated online, e-books are protected by digital rights management (DRM), a technological lock that allows copyright holders to protect their rights by controlling what users can do with their digital files. DRM can determine variables such as under what circumstances, how many times, for how long, and on which devices a file can be accessed. This lock, in turn, is protected by anti-circumvention laws that prohibit users from changing or removing it. As a rule, these laws do not require the architecture of DRM systems to comply with the same limits and exceptions that apply to copyright. As a result, it is possible for DRM systems to establish new rules on the use of artwork beyond the legal protection afforded by intellectual property laws. In the digital book market, such rules have a particular impact on competition. Since booksellers use different proprietary DRM schemes on their digital books, compatible with a limited number of reading platforms, readers face interoperability problems in acquiring e-books from a different store than the one in which the reading device was bought. This low interoperability locks readers into a particular ecosystem and increases network effects, switching costs and barriers to entry in this market, leading to concentration. As a result, bookstores are able to exercise great power over the flow of information in this market, undermining the potential of e-books to spread knowledge and promote reading. Thus, this research examines how DRM systems and anti-circumvention laws affect competition in the digital book market, and how this competitive dynamic, in turn, impacts access to books. The analysis begins with a description of the digital book market and advances to a theoretical discussion, consisting of a review of specialized literature on copyright, competition law, and access to knowledge. Under a development as freedom perspective, this research concludes that a review of anticircumvention laws is essential for promoting competition in this market, guaranteeing individual autonomy, and realizing the potential of e-books to expand access to knowledge.

Copyright is essentially the right of the rightsholder of an original work to prohibit others from making or distributing unauthorised copies of his or her work. More specifically for this dissertation, when an end user deals with digital content, one of the aims of copyright becomes the balancing of the conflicting interests in ‘exclusivity’ on the one hand, and in ‘access to information’ on the other. Exclusivity is achieved by the rightsholders through technological protection measures to protect their commercial interests. Access to information is achieved where works are available to the general public without payment and technological protection measures and where the digital content is not directly marketed for commercial gain. Exclusivity and access to information are two conflicting cultures surrounding copyright in the digital era. It is submitted that unless we find a socio-economic-legal way for the dynamic coexistence of these two conflicting cultures by means of fair dealing, the culture of exclusivity will eventually dominate fair access to information. The transient nature of digital content means that rightsholders have little or no control over their works once the end user has obtained a legal digital copy of the work. The right ‘to prohibit’ end users from copying and distributing unauthorised copies is, therefore, largely meaningless unless a legal or other solution can be found to discourage end users from the unauthorised reproduction and distribution of unauthorised copies of the work. Currently, technological protection measures are used to manage such digital rights because legal permissions within the doctrine of fair dealing for works in printed (analogue) format are inadequate. It is, however, submitted that a legal solution to discourage end users from copying and distributing unauthorised copies rests on two pillars. Firstly, the solution must be embedded in state-of-the-art digital rights management systems and secondly the business model used by publishers, and academic publishers in particular, should change fundamentally from a business-to-consumer model to a business-to-business model. Empirical evidence shows that the printing of e-content will continue to be relevant far into the future. Therefore, the management of fair dealing to allow for the printing of digital content will become increasingly important at educational institutions that use e-books as prescribed course material. It is submitted that although the origination cost of print editions and e-books correspond, the relatively high retail price of e-books appears to be based on the fact that academic publishers of digital content do not have the legal or digital rights management tools to manage the challenges arising from the fair dealing doctrine. The observation that academic publishers are reluctant to grant collecting societies mandates to manage the distribution of digital content, and/or the right to manage the authorised reproduction (printing) of the digital content, supports this hypothesis. Ultimately, with technologies at our disposal, the fair use of content in digital and print format can be achieved because it should simply be cheaper to comply with copyright laws than to make unauthorised digital or printed copies of content that our society desperately needs to make South Africa a winning nation. / Mercantile Law / LL.
