Digital Public Domain vs yottabytes de la NSA ?

Une parution du projet EuropĂ©en Communia et une information sur les moyens considĂ©rables du nouveau projet de la NSA, dont la puissance s’Ă©value maintenant en yottabytes (10 PUISSANCE 24 bytes ! ) :  deux exemples illustrant l’enjeu de batailles techno-politiques,  d’affrontements au devant…

Alors que la technologie numĂ©rique rend la culture plus accessible que jamais, les droits relatifs Ă  l’usage des biens culturels deviennent plus restrictifs. Face Ă  cette Ă©volution paradoxale, des chercheurs, universitaires, bibliothĂ©caires, entrepreneurs, militants et dĂ©cideurs politiques, rĂ©unis au sein du projet Communia, financĂ© de 2007 Ă  2011 par l’Union EuropĂ©enne et Ă  l’origine de l’association internationale Communia sur le domaine public numĂ©rique, ouvrent la discussion et apportent des solutions concrètes Ă  la difficile question de la rĂ©gulation de la culture Ă  l’ère numĂ©rique.

Quant au projet de la NSA, il s’agit de la construction du plus grand centre d’espionnage du pays.  OpĂ©rationnel Ă  fin 2013. Extraits de l’article de la revue Wired du 15 mars 2012 (consultable ici) :

“The NSA has become the largest, most covert, and potentially most intrusive intelligence agency ever.[ ]

As a result of this “expanding array of theater airborne and other sensor networks,” as a 2007 Department of Defense report puts it, the Pentagon is attempting to expand its worldwide communications network, known as the Global Information Grid, to handle yottabytes (1024bytes) of data. (A yottabyte is a septillion bytes—so large that no one has yet coined a term for the next higher magnitude.)

It needs that capacity because, according to a recent report by Cisco, global Internet traffic will quadruple from 2010 to 2015, reaching 966 exabytes per year. (A million exabytes equal a yottabyte.) In terms of scale, Eric Schmidt, Google’s former CEO, once estimated that the total of all human knowledge created from the dawn of man to 2003 totaled 5 exabytes. And the data flow shows no sign of slowing. In 2011 more than 2 billion of the world’s 6.9 billion people were connected to the Internet. By 2015, market research firm IDC estimates, there will be 2.7 billion users. Thus, the NSA’s need for a 1-million-square-foot data storehouse. Should the agency ever fill the Utah center with a yottabyte of information, it would be equal to about 500 quintillion (500,000,000,000,000,000,000) pages of text.

[ ]The data stored in Bluffdale will naturally go far beyond the world’s billions of public web pages. The NSA is more interested in the so-called invisible web, also known as the deep web or deepnet—data beyond the reach of the public.

[ ] Once the communications are intercepted and stored, the data-mining begins. “You can watch everybody all the time with data- mining,” Binney says. Everything a person does becomes charted on a graph, “financial transactions or travel or anything,” he says. Thus, as data like bookstore receipts, bank statements, and commuter toll records flow in, the NSA is able to paint a more and more detailed picture of someone’s life.”
