What is DRM?

DRM is an abbreviation for managing digital rights, a wide term used to describe a number of techniques to reduce free use and transmission of digital content. DRM is used in a number of media, but most often occurs in videos and music files. There are many people claiming that DRM is an incorrect name because it deals with use rather than consumer rights. Therefore, they reinterpret DRM to be worth managing digital restrictions. With decreasing sale, so the argument continues, creative entry will also decrease and the total quality of the media produced will fall. Most of the media is protected by copyright, but has a fair use clause that allows harmless use in certain situations. All existing DRM technologies cannot adequately make concessions for fair use, leading many civil lawyers to claim that they reduce the legal use of content.

isI have the first and largest DRM systems was the SCRAMBLING SYSTEM (CSS) system used to encode DVD movie files. This system was developed by the DVD consortium as a tool for influencing hardware to produce only systems that did not include a certain feature. By issuing an encryption key for CSS only for hardware manufacturers who agreed that they did not include functions such as digital out, which would make it easy to copy the film, the DVD consortium was basically able to dictate hardware policies for DVD industry.

very quickly after the implementation of CSS DRM, its algorithm was broken. Tools such as DECSS were available for creating copies of CSS Incrypted movies and playing on systems that would not otherwise be able to, such as some alternative operating systems. The Copyright Act for the Digital Millennium in the United States makes it unlawful to use systems such as DECSS to circumvent DRM restrictions. Similar acts have been handed over since then in many countries. Many of the rightsDMCA considers Achi in the world of computer science to be a main wound against creative freedom because of his too hard restrictions.

While DRM is most commonly used for movies, it also gains more widespread use in other media. Sound files purchased in many online stores such as the Apple iTunes Store have different DRM schemes that limit the number of devices on which they can be played. Many E -Knih manufacturers use a similar DRM implementation to reduce how many computers can display the book, and even how many times they can be viewed. In the middle of 2005, Number producers for television began to demand DRM of its programs through the popular TIVO system.

Problems of Security, Problems with Righteous Use and Creative Expression Problems are at the forefront of DRM battle, and DRM technology will undoubtedly be fought for many more years. While many in the media industry believe that DRM is the only way to save their existing business model,Based on the idea of ​​collecting a fee for every use, many innovators began to explore alternatives and predict the final defeat for DRM.
