Copy protection (English:) is also called content protection (content protection), copy prevention (copy prevention) or copy restriction (copy restriction), etc., is an action taken to prevent software, movies, music or other works from being copied , usually by for copyright protection purposes. Numerous methods have been devised in the world to discourage copying so that everyone will buy legally authorized copies of the company's products, benefiting the company. In the United States alone in the 1990s, unauthorized copying and distribution caused $2.4 billion in lost revenue and was seen to have impacted the revenues of the music and video game industries, leading to stricter regulations such as the Protection of Intellectual Property Rights Act ( PIPA ) copyright law. Some copy protection methods have been criticized for inconveniencing consumers or silently installing additional or unnecessary copy detection software. Effective copyright protection while protecting consumer rights remains an ongoing issue in the media publishing world.
Anti-piracy infringement
Anti-piracy file sharing
In the modern technological society, copyright infringement is often achieved through file sharing . According to statistics in 2011, infringing content accounted for about 23.8% of Internet traffic. To mitigate this, various media companies have issued Digital Millennium Copyright Act (DMCA) takedown notices, filed lawsuits, and brought criminal charges against providers of file-sharing services.
