    Mega, Digital Storage Lockers, and the DMCA: Will Innovation Be Stifled by Fears of Piracy?

    Kim Dotcom, founder of Megaupload Limited, has been in many news headlines over the past year. Megaupload—one of Dotcom’s many peer-to-peer sharing sites—was the center of controversy, as it allowed users to upload and share all sorts of files, including copyrighted material. After an organized effort by the Department of Justice and several foreign governments, Dotcom was arrested for (secondary) copyright infringement and his site was ultimately shut down. Dotcom has recently launched a new service, MEGA, which he claims will evade copyright laws entirely. Like other well-known cloud-sharing services such as Dropbox and Google Drive, MEGA allows users to upload files and to share them with select users. In an attempt to avoid liability, MEGA locally encrypts all files on the user’s computer before they are uploaded to the site. The private key and public key used to encrypt and decrypt the file are retained solely by the user; MEGA gets no part of that information. This, Dotcom argues, will shift the entirety of the copyright onus to the user. This Issue Brief analyzes the protections afforded cyberlocker services like MEGA by the DMCA, including tensions raised in actual litigation. This Issue Brief argues that, while an ex ante secondary-liability analysis is difficult due to its contextual nature, MEGA’s use of user-controlled encryption (UCE), deduplication, and distributed host servers may lend to an affirmative finding of liability

    Research report funded by the DC-NET project.An overview of the state of the art in service provision for digital preservation and curation. Its focus is on the areas where bridging the gaps is needed between e-Infrastructures and efficient and forward-looking digital preservation services. Based on a desktop study and a rapid analysis of some 190 currently available tools and services for digital preservation, the deliverable provides a high-level view on the range of instruments currently on offer to support various functions within a preservation system.European Commission, FP7peer-reviewe

    A framework for P2P application development

    Get PDF
    Although Peer-to-Peer (P2P) computing has become increasingly popular over recent years, there still exist only a very small number of application domains that have exploited it on a large scale. This can be attributed to a number of reasons including the rapid evolution of P2P technologies, coupled with their often-complex nature. This paper describes an implemented abstraction framework that seeks to aid developers in building P2P applications. A selection of example P2P applications that have been developed using this framework are also presented

    How can SMEs benefit from big data? Challenges and a path forward

    Get PDF
    Big data is big news, and large companies in all sectors are making significant advances in their customer relations, product selection and development and consequent profitability through using this valuable commodity. Small and medium enterprises (SMEs) have proved themselves to be slow adopters of the new technology of big data analytics and are in danger of being left behind. In Europe, SMEs are a vital part of the economy, and the challenges they encounter need to be addressed as a matter of urgency. This paper identifies barriers to SME uptake of big data analytics and recognises their complex challenge to all stakeholders, including national and international policy makers, IT, business management and data science communities. The paper proposes a big data maturity model for SMEs as a first step towards an SME roadmap to data analytics. It considers the ‘state-of-the-art’ of IT with respect to usability and usefulness for SMEs and discusses how SMEs can overcome the barriers preventing them from adopting existing solutions. The paper then considers management perspectives and the role of maturity models in enhancing and structuring the adoption of data analytics in an organisation. The history of total quality management is reviewed to inform the core aspects of implanting a new paradigm. The paper concludes with recommendations to help SMEs develop their big data capability and enable them to continue as the engines of European industrial and business success.

    Deep Space Network information system architecture study

    Get PDF
    The purpose of this article is to describe an architecture for the Deep Space Network (DSN) information system in the years 2000-2010 and to provide guidelines for its evolution during the 1990s. The study scope is defined to be from the front-end areas at the antennas to the end users (spacecraft teams, principal investigators, archival storage systems, and non-NASA partners). The architectural vision provides guidance for major DSN implementation efforts during the next decade. A strong motivation for the study is an expected dramatic improvement in information-systems technologies, such as the following: computer processing, automation technology (including knowledge-based systems), networking and data transport, software and hardware engineering, and human-interface technology. The proposed Ground Information System has the following major features: unified architecture from the front-end area to the end user; open-systems standards to achieve interoperability; DSN production of level 0 data; delivery of level 0 data from the Deep Space Communications Complex, if desired; dedicated telemetry processors for each receiver; security against unauthorized access and errors; and highly automated monitor and control
