Beginning on page two of this journal article the author discusses anti-piracy technologies that major music labels are integrating or testing out in order to combat online file sharing. Certain copyright protection systems already implemented by Sony and Bertelsman Music Group (BMG) encode CDs with electronic implements so that they can only be played on a CD player. Sony developed their own anti-piracy technology which they called "key2audio." This piece of technology prevented the use of CDs on personal computers and DVD players. A later version called "key2audio4pc" allows for use on computer but not multiple computers. The music label BMG Entertainment used another company known as Midbar technology to develop a program called Cactus Data Shield. This program prevents individuals from reformatting songs into MP3 files so that they can either make copies or make them available through file-sharing. Two other companies Macrovision and TTR Technologies developed different versions of a technology called Safe Audio. Safe Audio Version 2 allows for use in CD players and PC CD-ROMS but adds background noise to the playback sound if a copy is made to the hard drive or a CD burner. Version 3 allows CDs to be played in CD players but not in CD-ROMS. The Safe Audio technology had difficulty selling in the United States due to fear of consumer's negativity towards the product. As a result of this the Macrovision company released the product SafeAuthenticate which allows CDs that are authenticated by the product's software to be copied to the hard drive and played using Windows Media Player.
In the conclusion of the article the author talks about the fact that technology is constantly becomming outdated and although it is frustrating for the technology industries they have to learn to adapt to the situation. He states that the anti-piracy software and inhibition of recording devices just brings frustration to consumers and retailers. She suggests that Congress should research what has worked and use that to make changes in order to adapt to the time period.
