History Of Attacks Against Advanced Access Content System
The security of Advanced Access Content System (AACS) has been a subject of discussion amongst security researchers, high definition video enthusiasts, and consumers at large since its inception. A successor to Content Scramble System (CSS), the digital rights management mechanism used by commercial DVDs, AACS was intended to improve upon the design of CSS by addressing flaws which had led to the DeCSS, total circumvention of CSS in 1999. The AACS system relies on a Tree (set theory), subset difference tree combined with a certificate revocation list, certificate revocation mechanism to ensure the security of high definition video content in the event of a compromise. Even before AACS was put into use, security researchers expressed doubts about the system's ability to withstand attacks. Comparison of CSS and AACS History of attacks The AACS proposal was voted one of the technologies most likely to fail by ''IEEE Spectrum'' magazine's readers in the January 2005 issue. Conce ...

Advanced Access Content System
The Advanced Access Content System (AACS) is a standard for content distribution and digital rights management, intended to restrict access to and copying of the post- DVD generation of optical discs. The specification was publicly released in April 2005 and the standard has been adopted as the access restriction scheme for HD DVD and Blu-ray Disc (BD). It is developed by AACS Licensing Administrator, LLC (AACS LA), a consortium that includes Disney, Intel, Microsoft, Panasonic, Warner Bros., IBM, Toshiba and Sony. AACS has been operating under an "interim agreement" since the final specification (including provisions for Managed Copy) has not yet been finalized. Since appearing in devices in 2006, several AACS decryption keys have been extracted from software players and published on the Internet, allowing decryption by unlicensed software. System overview Encryption AACS uses cryptography to control and restrict the use of digital media. It encrypts content under one or ...

HD DVD
HD DVD (short for High Definition Digital Versatile Disc) is an obsolete high-density optical disc format for storing data and playback of high-definition video. Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format. HD DVD employed a blue laser with a shorter wavelength (with the exception of the 3× DVD and HD REC variants), and it stored about 3.2 times as much data per layer as its predecessor (maximum capacity: 15 GB per layer compared to 4.7 GB per layer on a DVD). The format was commercially released in 2006 and fought a protracted format war with rival Blu-ray. On February 19, 2008, Toshiba abandoned the format, announcing it would no longer manufacture HD DVD players and drives. The HD DVD Promotion Group was dissolved on March 28, 2008. The HD DVD physical disc specifications (but not the codecs) were used as the basis for the China Blue High-definition Disc (CBHD) formerly called CH-DVD. History In the la ...

Virtual Machine
In computing, a virtual machine (VM) is the virtualization/ emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination. Virtual machines differ and are organized by their function, shown here: * '' System virtual machines'' (also termed full virtualization VMs) provide a substitute for a real machine. They provide functionality needed to execute entire operating systems. A hypervisor uses native execution to share and manage hardware, allowing for multiple environments which are isolated from one another, yet exist on the same physical machine. Modern hypervisors use hardware-assisted virtualization, virtualization-specific hardware, primarily from the host CPUs. * Process virtual machines are designed to execute computer programs in a platform-independent environment. Some virtual machine emulators, such as QEMU a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wikipedia
Wikipedia is a multilingual free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and using a wiki-based editing system. Wikipedia is the largest and most-read reference work in history. It is consistently one of the 10 most popular websites ranked by Similarweb and formerly Alexa; Wikipedia was ranked the 5th most popular site in the world.

Sanger coined its name as a blend of ''wiki'' and '' encyclopedia''. Wales was influenced by the " spontaneous order" ideas associated with Friedrich Hayek and the Austrian School of economics after being exposed to these ideas by the libertarian economist Mark Thornton. Initially available only in English, versions in other languages were quickly developed. Its combin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In July 2008, the former company took part in advanced acquisition talks with Google for a reported $200 million price tag, but the deal ultimately fell through. After a controversial 2010 redesign and the departure of co-founders Jay Adelson and Kevin Rose, in July 2012 Digg was sold in three parts: the Digg br ...

DMCA Takedown Notice
The Online Copyright Infringement Liability Limitation Act (OCILLA) is United States federal law that creates a conditional 'safe harbor' for online service providers (OSP) (a group which includes internet service providers (ISP) and other Internet intermediaries) by shielding them for their own acts of direct copyright infringement (when they make unauthorized copies) as well as shielding them from potential secondary liability for the infringing acts of others. OCILLA was passed as a part of the 1998 Digital Millennium Copyright Act (DMCA) and is sometimes referred to as the "Safe Harbor" provision or as "DMCA 512" because it addeSection 512to Title 17 of the United States Code. By exempting Internet intermediaries from copyright infringement liability provided they follow certain rules, OCILLA attempts to strike a balance between the competing interests of copyright owners and digital users. Overview The 1998 DMCA was the U.S. implementation of the 1996 WIPO Copyright Treat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BitTorrent Tracker
A BitTorrent tracker is a special type of server that assists in the communication between peers using the BitTorrent protocol. In peer-to-peer file sharing, a software client on an end-user PC requests a file, and portions of the requested file residing on peer machines are sent to the client, and then reassembled into a full copy of the requested file. The "tracker" server keeps track of where file copies reside on peer machines, which ones are available at time of the client request, and helps coordinate efficient transmission and reassembly of the copied file. Clients that have already begun downloading a file communicate with the tracker periodically to negotiate faster file transfer with new peers, and provide network performance statistics; however, after the initial peer-to-peer file download is started, peer-to-peer communication can continue without the connection to a tracker. Modern BitTorrent clients may implement a distributed hash table and the peer exchange prot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
