DVD region codeDVD region codes are a digital rights management technique introduced in 1997. It is designed to allow rights holders to control the international distribution of a DVD release, including its content, release date, and price, all according to the appropriate region. This is achieved by way of region-locked DVD players, which will play back only DVDs encoded to their region (plus those without any region code). The American DVD Copy Control Association also requires that DVD player manufacturers incorporate the regional-playback control (RPC) system.
KeygenA key generator (key-gen) is a computer program that generates a product licensing key, such as a serial number, necessary to activate for use of a software application. Keygens may be legitimately distributed by software manufacturers for licensing software in commercial environments where software has been licensed in bulk for an entire site or enterprise, or they may be distributed illegitimately in circumstances of copyright infringement or software piracy.
Copyright infringementCopyright infringement (at times referred to as piracy) is the use of works protected by copyright without permission for a usage where such permission is required, thereby infringing certain exclusive rights granted to the copyright holder, such as the right to reproduce, distribute, display or perform the protected work, or to make derivative works. The copyright holder is typically the work's creator, or a publisher or other business to whom copyright has been assigned.
Copy protectionCopy protection, also known as content protection, copy prevention and copy restriction, describes measures to enforce copyright by preventing the reproduction of software, films, music, and other media. Copy protection is most commonly found on videotapes, DVDs, Blu-ray discs, HD-DVDs, computer software discs, video game discs and cartridges, audio CDs and some VCDs. Some methods of copy protection have also led to criticism because it caused inconvenience for paying consumers or secretly installed additional or unwanted software to detect copying activities on the consumer's computer.
Cory DoctorowCory Efram Doctorow (ˈkɒri_ˈdɒktəroʊ; born July 17, 1971) is a Canadian-British blogger, journalist, and science fiction author who served as co-editor of the blog Boing Boing. He is an activist in favour of liberalising copyright laws and a proponent of the Creative Commons organization, using some of its licences for his books. Some common themes of his work include digital rights management, , and post-scarcity economics. Cory Efram Doctorow was born in Toronto, Ontario, on 17 July 1971.
Software protection dongleA software protection dongle (commonly known as a dongle or key) is an electronic copy protection and content protection device. When connected to a computer or other electronics, they unlock software functionality or decode content. The hardware key is programmed with a product key or other cryptographic protection mechanism and functions via an electrical connector to an external bus of the computer or appliance. In software protection, dongles are two-interface security tokens with transient data flow with a pull communication that reads security data from the dongle.
Product activationProduct activation is a license validation procedure required by some proprietary software programs. Product activation prevents unlimited free use of copied or replicated software. Unactivated software refuses to fully function until it determines whether it is authorized to fully function. Activation allows the software to stop blocking its use. An activation can last "forever", or it can have a time limit, requiring a renewal or re-activation for continued use.
Trusted clientIn computing, a trusted client is a device or program controlled by the user of a service, but with restrictions designed to prevent its use in ways not authorized by the provider of the service. That is, the client is a device that vendors trust and then sell to the consumers, whom they do not trust. Examples include video games played over a computer network or the Content Scramble System (CSS) in DVDs. Trusted client software is considered fundamentally insecure: once the security is broken by one user, the break is trivially copyable and available to others.
Screen readerA screen reader is a form of assistive technology (AT) that renders text and image content as speech or braille output. Screen readers are essential to people who are blind, and are useful to people who are visually impaired, illiterate, or have a learning disability. Screen readers are software applications that attempt to convey what people with normal eyesight see on a display to their users via non-visual means, like text-to-speech, sound icons, or a braille device.
First-sale doctrineThe first-sale doctrine (also sometimes referred to as the "right of first sale" or the "first sale rule") is an American legal concept that limits the rights of an intellectual property owner to control resale of products embodying its intellectual property. The doctrine enables the distribution chain of copyrighted products, library lending, giving, video rentals and secondary markets for copyrighted works (for example, enabling individuals to sell their legally purchased books or CDs to others).
