Problems of Copyright Management and Control Technologies Profiling and Data Mining At their most basic copyright management and control technologies might simply be used to provide pricing information, negotiate the purchase transaction, and release a copy of a work for downloading to the customer's computer. Still, from a technological point of view, such systems also have the capacity to be employed for digital monitoring. Copyright owners could for example use the transaction records generated by their copyright management systems to learn more about their customers. Profiles, in their crudest form consisting of basic demographic information, about the purchasers of copyrighted material might be created. Moreover copyright owners could use search agents or complex data mining techniques to gather more information about their customers that could either be used to market other works or being sold to third parties. Fair Use Through the widespread use of copyright management and control systems the balance of control could excessively be shifted in favor of the owners of intellectual property. The currently by copyright law supported practice of fair use might potentially be restricted or even eliminated. While information in analogue form can easily be reproduced, the protection of digital works through copyright management systems might complicate or make impossible the copying of material for purposes, which are explicitly exempt under the doctrine of fair use. Provisions concerning technological protection measures and fair use are stated in the DMCA, which provides that "Since copying of a work may be a fair use under appropriate circumstances, section 1201 does not prohibit the act of circumventing a technological measure that prevents copying. By contrast, since the fair use doctrine is not a defense e to the act of gaining unauthorized access to a work, the act of circumventing a technological measure in order to gain access is prohibited." Also the proposed EU Directive on copyright and related rights in the information society contains similar clauses. It distinguishes between the circumvention of technical protection systems for lawful purposes (fair use) and the circumvention to infringe copyright. Yet besides a still existing lack of legal clarity also very practical problems arise. Even if the circumvention of technological protection measures under fair use is allowed, how will an average user without specialized technological know-how be able to gain access or make a copy of a work? Will the producers of copyright management and control systems provide fair use versions that permit the reproduction of copyrighted material? Or will users only be able to access and copy works if they hold a digital "fair use license" ("fair use licenses" have been proposed by Mark Stefik, whereby holders of such licenses could exercise some limited "permissions" to use a digital work without a fee)?

The Post-World-War II-period After World War II the importance of propaganda still increased, on the commercial level as well as on a political level, in the era of the Cold War. The propaganda institutions of the different countries wanted their people to think the right way, which meant, the national way. In the USA the McCarthy-era started, a totalitarian system in struggle against communism. McCarthy even managed to publicly burn critical books that were written about him; and every unbeloved artist was said to be a communist, an out-law. Cold War brought the era of spies with it, which was the perfect tool of disinformation. But the topic as a movie-genre seems still popular today, as the unchanged success of James Bond-movies show. A huge net of propaganda was built up for threatening with the nuclear bomb: pretending that the enemy was even more dangerous than the effect of such a bomb. And later, after the fall of the Iron Curtain, disinformation found other fields of work, like the wars of the 1990s showed us.

Backbone Networks Backbone networks are central networks usually of very high bandwidth, that is, of very high transmitting capacity, connecting regional networks. The first backbone network was the NSFNet run by the National Science Federation of the United States.

IIPA The International Intellectual Property Alliance formed in 1984 is a private sector coalition and represents the U.S. copyright-based industries. It is comprised of seven trade associations: Association of American Publishers, AFMA, Business Software Alliance, Interactive Digital Software Association, Motion Picture Association of America, National Music Publishers' Association and Recording Industry Association of America. IIPA and its member's track copyright legislative and enforcement developments in over 80 countries and aim at a legal and enforcement regime for copyright that deters piracy. On a national level IIPA cooperates with the U.S. Trade Representative and on the multilateral level has been involved in the development of the TRIPS (Trade-Related Aspects of Intellectual Property Rights) agreement of the WTO (World Trade Organization) and also participates in the copyright discussion of the WIPO (World Intellectual Property Organization).
