Jon Lech Johansen, un joven noruego descifró el código de seguridad que impide a los usuarios del reproductor de música digital iPod de Apple utilizar canciones compradas en otras tiendas online que no sea iTunes Music Store.
(DT, AGENCIAS) El joven logró la hazaña revirtiendo el sistema anti-copía FairPlay de Apple, instalado en cada uno de los iPod.
Esta tecnología impide que las canciones comprada en la tienda iTunes sean transferidas a otros dispositivos que no sean iPod, así como tampoco permite que la música adquirida en otras tiendas online se utilicen en el reproductor de Apple.
Pero el descubrimiento de Johansen podría cambiar este panorama si otras compañías valiéndose de este código quiebran el dominio de iTunes y empiezan a ofrece música compatible con iPod.
En DoubleTwist, compañía donde trabaja este hacker, parecen entender que el descubrimiento es una verdadera mina de oro y ya anunciaron que tiene planes autorizar el uso del código a otros compañías, informó la Reuters.

Hacker unlocks Apple music download protection
Tue Oct 24, 2006 8:55pm ETSAN FRANCISCO (Reuters) - A hacker who as a teen cracked the encryption on DVDs has found a way to unlock the code that prevents iPod users from playing songs from download music stores other than Apple Computer Inc.'s iTunes, his company said on Tuesday.
Jon Lech Johansen, a 22-year-old Norway native who lives in San Francisco, cracked Apple's FairPlay copy-protection technology, said Monique Farantzos, managing director at DoubleTwist, the company that plans to license the code to businesses.
"What he did was basically reverse-engineer FairPlay," she said. "This allows other companies to offer content for the iPod."
At the moment, Apple aims to keep music bought from its iTunes online music store only available for Apple products, while songs bought from other online stores typically do not work on iPods.
But Johansen's technology could help rivals sell competing products that play music from iTunes and offer songs for download that work on iPods as they seek to take a bite out of Apple's dominance of digital music.
ITunes commands an 88 percent share of legal song downloads in the United States, while the iPod dominates digital music player sales with more than 60 percent of the market.
Cupertino, California-based Apple, whose profits have soared in recent years on the strength of the iPod, declined to comment.
Johansen, known as DVD Jon, gained fame when at the age of 15 he wrote and distributed a program that cracked the encryption codes on DVDs. This allowed DVDs to be copied and played back on any device.
His latest feat could help companies such as Microsoft Corp., Nokia, Sony Ericsson and Samsung Electronics Co. Ltd., which have all announced plans over the past few months for music download services combined with new devices to challenge Apple.

BAGHDAD (Reuters) - The U.S. military has begun looking more closely at shooting attacks on troops in Iraq to establish whether they are carried out by snipers, according to a spokesman.
The change reflects concern over an insurgent video-CD that appears to show a series of shooting attacks on U.S. and Iraqi forces in Baghdad by a purported sniper brigade from the Sunni militant Islamic Army.
The video, which Reuters has seen, was handed out in Sunni parts of western Baghdad last week as a "gift" to mark the end of the Muslim fasting month of Ramadan. It shows 28 separate attacks, several of them involving precision shots to the head.
Narrated by a man described as the brigade "commander" and subtitled in English, it claims the marksmen use a training manual written by a retired U.S. Army Special Forces officer.
"Ultimate Sniper", written in 1993 by Major John L. Plaster, is freely available through online bookstores. It was updated this year "for today's Global War on Terror", according to www.ultimatesniper.com, which calls it the bible of sniping.
Spokesman Lieutenant-Colonel Christopher Garver said the U.S. military was aware of the video.
He said the military was taking unspecified steps to reduce the possible new threat and had begun to examine killings by small arms fire in greater detail. "We are being more specific in trying to hone in on sniper tactics," Garver said.
U.S. casualty reports list three killings by sniper fire in Baghdad this year, all since July, and 24 by small arms fire, 10 of them in October.'NOTCHING UP KILLS'
The 28-minute propaganda video opens with musings from a black-masked man identified as "Juba, the Baghdad Sniper".
Reports of a lone sniper nicknamed Juba prowling Baghdad surfaced last year. The new footage shows the man adding another "kill" to a list of 37 hits on a piece of paper on a wall.
The "commander", however, says the Islamic Army now has "a fair amount of snipers" with the steady hand and eagle eye required for the task.
"The idea of filming the operations is very important because the scene that shows the falling soldier when hit has more impact on the enemy than any other weapon," says the "commander", whose face is obscured.
Garver said he had not seen the video, called "Juba Returns". He said sniping was "another threat that we have to worry about" but questioned whether all the attacks were the work of accomplished sharpshooters.
"They could be a lucky shot with a good rifle," Garver said. "Having a scope does not necessarily qualify you as a trained sniper."
The U.S. military does not require units to attribute killings specifically to sniper fire, although some do.
According to the Web site www.icasualties.org, which tracks the official casualty toll in Iraq and Afghanistan, 38 U.S. troops have been killed by sniper fire in Iraq since the start of the war in March 2003, seven of them this year.Deaths attributed to unspecified small arms fire total about 230, including 80 this year.
The video says the brigade's main weapon is the Tabuk sniper rifle, which was produced in Iraq from a Yugoslav design.
It uses standard Kalashnikov rounds and probably has a range of 500-600 metres (yards), according to arms Web sites which describe it as more of a marksman's rifle than a sniper rifle, which is designed to be accurate beyond 800 meters (yards).
