  • Secure Remote Service Execution for Web Media Streaming
    Secure Remote Service Execution for Web Media Streaming vorgelegt von Dipl.-Ing. Alexandra Mikityuk geb. in Leningrad, UdSSR von der Fakultät IV – Elektrotechnik und Informatik der Technischen Universität Berlin zur Erlangung des akademischen Grades Doktor der Ingenieurwissenschaften - Dr.-Ing. - genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr. Thomas Magedanz, Technische Universität Berlin Gutachter: Prof. Dr. Jean-Pierre Seifert, Technische Universität Berlin Gutachter: Prof. Dr. Jean-Claude Dufourd, ParisTech Gutachter: Prof. Dr.-Ing. Ina Schieferdecker, Technische Universität Berlin Tag der wissenschaftlichen Aussprache: 29. August 2017 Berlin 2017 D 83 Abstract Through continuous advancements in streaming and Web technologies over the past decade, the Web has become a platform for media delivery. Web standards like HTML5 have been designed accordingly, allowing for the delivery of applications, high-quality streaming video, and hooks for interoperable content protection. Efficient video encoding algorithms such as AVC/HEVC and streaming protocols such as MPEG-DASH have served as additional triggers for this evolution. Users now employ Web browsers as a tool for receiving streaming media and rendering Web applications, and browsers have been embedded into almost every kind of connected device. The drawback of these technical developments and quick rate of user adoption is that modern Web browsers have introduced significant constraints on devices’ capabilities. First, the computational requirements have risen continuously, resulting in a cycle where modern devices can be nearly outdated after a year or two. Second, as the integration of browser technologies is a complicated matter, not every platform provides the same performance. Different Operating Systems (OSs), chipsets and software engines are the main reasons for this difference in performance.

    UNIVERSITY OF NEWCASTLE University of Newcastle upon Tyne COMPUTING SCIENCE A Trust-economic Perspective on Information Security Technologies S. E. Parkin and A. van Moorsel TECHNICAL REPORT SERIES No. CS-TR-1056 October, 2007 TECHNICAL REPORT SERIES No. CS-TR-1056 October, 2007 A Trust-economic Perspective on Information Security Technologies Simon Edward Parkin and Aad van Moorsel Abstract This report surveys existing enterprise technologies and products available to control access to confidential digital data. We survey USB access control solutions, digital rights management software, disk encryption techniques and operating system solutions. We compare the various technologies with respect to granularity and extent of administrative control, platform coverage, user education features, and accommodation of data use outside the boundaries of the company network. The researched technologies allow restrictions to be placed on copying, editing, viewing and printing from within various software applications, provide auditing options and prevent outsider access through encryption. Several of the mentioned technologies offer training and education options, informing users as to the reasoning of access control events as they occur and educating them about the permissions that apply to them. A serious drawback of many of the technologies is the central administration it requires. We are interested in cost trade-off, to be able to make trust-economic decisions. The cost of software deployment is linked to the features that each product provides, where finer granularity of device and file content control, encryption and user education implies that per-user purchase cost increases. © 2007 University of Newcastle upon Tyne.

The advent of personal control technologies that can be used by hardware manufacturers, computers as household appliances has made it publishers, copyright holders and individuals to impose convenient for consumers to convert media originally in a limitations on the usage of digital content and devices. The term physical/analog form or a broadcast form into a universal, is used to describe any technology that inhibits uses of digital digital form for location- or time shifting. This, combined content not desired or intended by the content provider. The with the Internet and popular file sharing tools, has made term does not generally refer to other forms of copy protection which can be circumvented without modifying the file or device, unauthorized distribution of copies of copyrighted digital such as serial numbers or key files. It can also refer to media much easier. restrictions associated with specific instances of digital works or devices. Digital rights management is used by companies such as Sony, Amazon, Apple Inc., Microsoft, AOL and the BBC. The Objective of the Study use of digital rights management is controversial. Proponents argue it is needed by copyright holders to prevent unauthorized Although technical controls on the reproduction and use duplication of their work, either to maintain artistic integrity or of software have been intermittently used since the 1970s, to ensure continued revenue streams.

  • Innovativ IKT, DRM Pipeline Protection
    Media Data Protection during Execution on Mobile Platforms – A Review Manoranjan Mohanty, Viktor Do, and Christian Gehrmann SICS Swedish ICT AB {manoranjan, viktordo, chrisg}@ sics.se 4 July 2014 SICS Technical Report: T2014:02 Abstract Multimedia content streaming has become an essential part of digital life. The media-on- demand (e.g., video on demand) service of certain enterprises, such as Netflix, Hulu, and Amazon etc. is changing the equations in which media content were accessed. The days, when one has to buy a bulk of media storage devices, or has to wait for the public broadcasting (e.g., television), to enjoy her preferred media has gone. Such change in the way of entertainment, however, has created new issues of piracy and unauthorized media access. To counter these concerns, the digital rights management (DRM) protection schemes have been adopted. In this report, we investigate one of the most important aspects of the DRM technology: the problem of protecting the clear text media content when playing licensing protected content on a mobile device. To this end, we first investigate how this problem has been addressed on different platforms and CPU architectures so far, and then discuss how virtualization technologies can be potentially used to protect the media pipe on mobile platforms. Our study will consider both industry-level and academic-level works, and will discuss the hardware- based and software-based approaches. Key Words: Digital Rights Management (DRM), ARM TrustZone, Hypervisor, Mobile DRM, Media Pipe Protection. 1 Introduction The advances in telecommunication and the availability of high-end mobile devices have resulted in a scenario where high quality multimedia data (such as video, audio, and image) is being streamed to anyone, anywhere, and at any time.
