Multimedia delivery in the future internet

The term “Networked Media” implies that all kinds of media including text, image, 3D graphics, audio and video are produced, distributed, shared, managed and consumed on-line through various networks, like the Internet, Fiber, WiFi, WiMAX, GPRS, 3G and so on, in a convergent manner [1]. This white paper is the contribution of the Media Delivery Platform (MDP) cluster and aims to cover the Networked challenges of the Networked Media in the transition to the Future of the Internet. Internet has evolved and changed the way we work and live. End users of the Internet have been confronted with a bewildering range of media, services and applications and of technological innovations concerning media formats, wireless networks, terminal types and capabilities. And there is little evidence that the pace of this innovation is slowing. Today, over one billion of users access the Internet on regular basis, more than 100 million users have downloaded at least one (multi)media file and over 47 millions of them do so regularly, searching in more than 160 Exabytes1 of content. In the near future these numbers are expected to exponentially rise. It is expected that the Internet content will be increased by at least a factor of 6, rising to more than 990 Exabytes before 2012, fuelled mainly by the users themselves. Moreover, it is envisaged that in a near- to mid-term future, the Internet will provide the means to share and distribute (new) multimedia content and services with superior quality and striking flexibility, in a trusted and personalized way, improving citizens’ quality of life, working conditions, edutainment and safety. In this evolving environment, new transport protocols, new multimedia encoding schemes, cross-layer inthe network adaptation, machine-to-machine communication (including RFIDs), rich 3D content as well as community networks and the use of peer-to-peer (P2P) overlays are expected to generate new models of interaction and cooperation, and be able to support enhanced perceived quality-of-experience (PQoE) and innovative applications “on the move”, like virtual collaboration environments, personalised services/ media, virtual sport groups, on-line gaming, edutainment. In this context, the interaction with content combined with interactive/multimedia search capabilities across distributed repositories, opportunistic P2P networks and the dynamic adaptation to the characteristics of diverse mobile terminals are expected to contribute towards such a vision. Based on work that has taken place in a number of EC co-funded projects, in Framework Program 6 (FP6) and Framework Program 7 (FP7), a group of experts and technology visionaries have voluntarily contributed in this white paper aiming to describe the status, the state-of-the art, the challenges and the way ahead in the area of Content Aware media delivery platforms

Piracy, File Sharing … And Legal Fig Leaves

Peer to Peer (P2P) platforms have been very effective in allowing the transmissionof large, bandwidth-intensive files (such as music and video) over the internet. Many such platformsare open source, and have been established by various operators as systems for the unauthoriseddistribution of copyright protected content.In addition to civil (and often criminal) liability faced bypersons establishing P2P platforms for the unlawful distribution of content, an end-user whodownloads copyright protected content from an unauthorised site risks civil action by the copyrightowner for breach of copyright by making an unauthorised copy of the file.The paper will look at thesignificant growth in P2P file sharing and its role as a medium for copyright piracy. The paper willexamine: how P2P file sharing facilitates internet piracy; the effect of case law; legislative changeswhich have taken place in an attempt to deter illegal distribution of copyright material through P2Pplatforms.; the effectiveness of strategies adopted by rights holders in an attempt to reduceunauthorised file sharing and ; protection measures available both for copyright owners seeking toavoid having their work illegally copied , and also third parties (such as ISPs and content hosts) whomay unknowingly become involved in the distribution of such material

Framework for privacy-aware content distribution in peer-to- peer networks with copyright protection

The use of peer-to-peer (P2P) networks for multimedia distribution has spread out globally in recent years. This mass popularity is primarily driven by the efficient distribution of content, also giving rise to piracy and copyright infringement as well as privacy concerns. An end user (buyer) of a P2P content distribution system does not want to reveal his/her identity during a transaction with a content owner (merchant), whereas the merchant does not want the buyer to further redistribute the content illegally. Therefore, there is a strong need for content distribution mechanisms over P2P networks that do not pose security and privacy threats to copyright holders and end users, respectively. However, the current systems being developed to provide copyright and privacy protection to merchants and end users employ cryptographic mechanisms, which incur high computational and communication costs, making these systems impractical for the distribution of big files, such as music albums or movies.El uso de soluciones de igual a igual (peer-to-peer, P2P) para la distribución multimedia se ha extendido mundialmente en los últimos años. La amplia popularidad de este paradigma se debe, principalmente, a la distribución eficiente de los contenidos, pero también da lugar a la piratería, a la violación del copyright y a problemas de privacidad. Un usuario final (comprador) de un sistema de distribución de contenidos P2P no quiere revelar su identidad durante una transacción con un propietario de contenidos (comerciante), mientras que el comerciante no quiere que el comprador pueda redistribuir ilegalmente el contenido más adelante. Por lo tanto, existe una fuerte necesidad de mecanismos de distribución de contenidos por medio de redes P2P que no supongan un riesgo de seguridad y privacidad a los titulares de derechos y los usuarios finales, respectivamente. Sin embargo, los sistemas actuales que se desarrollan con el propósito de proteger el copyright y la privacidad de los comerciantes y los usuarios finales emplean mecanismos de cifrado que implican unas cargas computacionales y de comunicaciones muy elevadas que convierten a estos sistemas en poco prácticos para distribuir archivos de gran tamaño, tales como álbumes de música o películas.L'ús de solucions d'igual a igual (peer-to-peer, P2P) per a la distribució multimèdia s'ha estès mundialment els darrers anys. L'àmplia popularitat d'aquest paradigma es deu, principalment, a la distribució eficient dels continguts, però també dóna lloc a la pirateria, a la violació del copyright i a problemes de privadesa. Un usuari final (comprador) d'un sistema de distribució de continguts P2P no vol revelar la seva identitat durant una transacció amb un propietari de continguts (comerciant), mentre que el comerciant no vol que el comprador pugui redistribuir il·legalment el contingut més endavant. Per tant, hi ha una gran necessitat de mecanismes de distribució de continguts per mitjà de xarxes P2P que no comportin un risc de seguretat i privadesa als titulars de drets i els usuaris finals, respectivament. Tanmateix, els sistemes actuals que es desenvolupen amb el propòsit de protegir el copyright i la privadesa dels comerciants i els usuaris finals fan servir mecanismes d'encriptació que impliquen unes càrregues computacionals i de comunicacions molt elevades que fan aquests sistemes poc pràctics per a distribuir arxius de grans dimensions, com ara àlbums de música o pel·lícules

Hail to the thief: a tribute to Kazaa

THIS PAPER CONSIDERS THE ONGOING LITIGATION against the peer-to-peer network KaZaA. Record companies and Hollywood studios have faced jurisdictional and legal problems in suing this network for copyright infringement. As Wired Magazine observes: “The servers are in Denmark. The software is in Estonia. The domain is registered Down Under, the corporation on a tiny island in the South Pacific. The users—60 million of them—are everywhere around the world.” In frustration, copyright owners have launched copyright actions against intermediaries—like against Internet Service Providers such as Verizon. They have also embarked on filing suits against individual users of file-sharing programs. In addition, copyright owners have called for domestic- and international-law reform with respect to digital copyright. The Senate Committee on Government Affairs of the United States Congress has reviewed the controversial use of subpoenas in suits against users of file-sharing peer-to-peer networks. The United States has encouraged other countries to adopt provisions of the Digital Millennium Copyright Act 1998 in bilateral and regional free-trade agreements

Fair use and file sharing in research and education

This work was inspired by the well-ventilated current problems around the use of digital file sharing technologies and their promotion of infringement of copyright leading to the alleged destruction of entertainment industries. Different legal systems have applied different analyses to such problems, and there is no clear and coherent answer to the question of whether file sharing, especially in the form of peer-to-peer (P2P), is legal. The particular focus of this thesis flows from the realisation that litigation around file sharing has uniformly explored it from the perspective of users downloading entertainment materials such as music and videos. Comparatively little attention has been paid to whether research and educational users have, or should have, rights to use the same digital file sharing technologies to access copyright materials important to their work. If digital file sharing is declared illegal by the courts at the behest of the entertainment industries, then what will happen to research and educational users of these networks?To explore this key problem, this thesis focuses on how fair use doctrine, the most important exception and limitation to copyright, has transferred from the traditional copyright environment into the context of digital file sharing. By undertaking a study of relevant legislation and cases, such as the well known Napster, Grokster and MP3.com, the “who” issue, namely, who is the party entitled to benefit from a fair use defence will be highlighted.Having established that fair use as a defence operates ineffectively in the digital file sharing environment, the thesis then looks at existing alternative or “fared” use models, and particularly the disadvantages of “fared” use system in serving research and educational file sharing. Finally the thesis turns to what is termed the “voluntary model”: a model in which copyright owners make their works available to academic users for free, via an institutional repository, the authors gaining non-pecuniary benefits while the commercial publisher being cut out as a “middleman”. Although future work to develop the details of this approach would be required, the thesis asserts this is a promising way towards ensuring access to copyright works in research and education thus benefiting society, whilst at the same time establishing fair compensation to authors for their efforts

Copyright Law in the Digital Age

Copyright infringement of digital media is an ever-increasing problem. While there have been attempts to solve this problem through both legal and technological measures, no solutions have been satisfactory. Many people are uneducated about the legal aspects, and technological measures are easily circumvented. By analyzing various documents and news articles, and by conducting interviews with various people representing all sides of the issue, the team was able assess the situation and to provide recommendations to improve it

Enforceability of digital copyright on the darknet?

This dissertation seeks to comparatively analyse different emerging jurisprudence of pioneering jurisdictions on the operability of enforcing digital copyright in light of the growing use of the Darknet. It addresses the legal lacuna in the existing copyright laws with regards to enforcement against the illegal distribution of infringing copies of online digital content. It also seeks to illustrate how the concept of digital copyright protection has been compromised by the inoperability of enforcement laws on illegal distribution via the Darknet. It thereby advocates for a 'digital use' exemption and or free access as a recommendation. Although the advancement of technology created new and advanced forms of distribution or availing copyrighted works to the public, these new advanced channels of distribution have been compromised by rogue online clandestine file sharing networks. Digital copyright protection laws have been advanced so as to respond to illegal online file sharing, however, they have had limited impact due to the vast, flexible and unregulated nature of the internet which transcends the territorial nature of any single state's copyright laws. Currently, online file sharing is effected through peer to peer networks due to their operational convenience. This dissertation suggests that the need to control distribution, legally or technological, is driven by the urge to enable digital copyright owners to benefit financially from their works and get a return on their investment. Technologically, this has been effected through the adoption of Digital Rights Management (DRMs) measures that control access to these works through the use of paywalls on commercial websites that require online consumers to pay/ subscribe first before they gain access to the copyrighted works. (eg Netflix, Showmax, itunes e.t.c) However, since absolute control over one's digital works, online, is impossible, the success of these access-control mechanisms remains debatable and remain vulnerable to technologically sophisticated users who could easily circumvent them and make the protected works available to millions of other users in Darknets. This, in effect, creates a parallel and free market for digital content. Darknets have grown as the new preferred channel of distribution due to their unique features which have rendered any judicial or legislative threat of sanctions, merely academic and detached from practical application. The Darknet essentially provides for user privacy, in anonymity, and security from monitoring and detection. These two primary features have exacerbated online piracy as various Darknets ISPs have now developed more user-friendly Darknet versions for the average mainstream user. This dissertation will highlight how the digital creative industry faces an existential threat with the growing use of Darknets. Darknets have created a virtual environment where illegal digital content distribution continues with impunity, since the burden of the enforceability of copyright rests squarely on the individual copyright holder and the pursuit of liability only begins upon detection of any such infringement of copyright. In effect, copyright owners, most often than not, lack the technological expertise to monitor and detect and thereby cannot enforce their copyright. As such, this dissertation postulates that the legal/ technological effort to maintain any form of monopoly over digital content online is an unattainable objective. As a solution, to end both online piracy and safeguarding the financial interests of copyright owners, a change in the approach to digital copyright is needed. This will be achieved through creating a 'digital use' exemption and or free access. Rather than copyright owners trying to control access, they should provide free access and profit on alternative revenue business models. Free access to digital content will do away with the need of online users to pirate and also save copyright owners the effort and resource to keep monitoring the virtual world for infringement. It will also counter-react to the Darknet's parallel market since users will have free access to digital content from the official distribution websites. This dissertation will interrogate the viability of this option
