Think Tanks and Corporate Money Looking at the financial situation of think tanks, different funding patterns can be found. While financial contributions from foundations play an important role especially for conservative think tanks, also contributions from governments are made to certain institutions. Yet one of the most important funding sources are corporate donors and individual contributors. Although the extent to which - in most cases conservative - think tanks rely on corporate funding varies, from the US$ 158 million spent by the top 20 conservative think tanks, more than half of it was contributed by corporations or businessmen. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Private data bunkers On the other hand are the data bunkers of the private sector, whose position is different. Although these are fast-growing engines of data collection with a much greater degree of dynamism, they may not have the same privileged position - although one has to differentiate among the general historical and social conditions into which a data bunker is embedded. For example, it can safely be assumed that the databases of a large credit card company or bank are more protected than the bureaucracies of small developing countries. Private data bunkers include

Copyright Management and Control Systems: Pre-Infringement Pre-infringement Contracts Contracts are a pre-infringement control method, which very often is underestimated. Properly formed contracts enable copyright holders to restrict the use of their works in excess of the rights granted under copyright laws. Copy Protection This approach was standard in the 1980s, but rejected by consumers and relatively easy to break. Still copy protection, whereby the vendor limits the number of times a file can be copied, is used in certain situations. Limited Functionality This method allows copyright owners to provide a copy of the work, which is functionally limited. Software creators, for example, can distribute software that cannot print or save. A fully functional version has to be bought from the vendor. Date Bombs Here the intellectual property holder distributes a fully functional copy but locks off access at a pre-specified date or after a certain number of uses. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Internet services The Internet can be used in in different ways: for distributing and retrieving information, for one-to-one, one-to-many and many-to-many communication, and for the access services. Accordingly, there are different services on offer. The most important of these are listed below. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Operating the net: overview The Net consists of thousands of thousands of governmental and private networks linked together. No legal authority determines how and where networks can be connected together, this is something the managers of networks have to agree about. So there is no way of ever gaining ultimate control of the Internet. Although each of these networks is operated and controlled by an organization, no single organization operates and controls the Net. Instead of a central authority governing the Net, several bodies assure the operability of the Net by developing and setting technical specifications for the Net and by the control of the technical key functions of the Net as the coordination of the domain name system and the allocation of IP numbers. Originally, the Net was a research project funded and maintained by the US Government and developed in collaboration by scientists and engineers. As the standards developed for ensuring operability ensued from technical functionality, technical coordination gradually grew out of necessity and was restricted to a minimum and performed by volunteers. Later, in the 1980s, those occupied with the development of technical specifications organized themselves under the umbrella of the Internet Society in virtual organizations as the Internet Engineering Task Force, which were neither officially established nor being based on other structures than mailing lists and commitment, but nonetheless still serve as task forces for the development of standards ensuring the interoperability on the Net. Since the late 80s and the early 90s, with the enormous growth of the Net - which was promoted by the invention of Since the year 2000, a new model for technical coordination has been emerging: Formerly performed by several bodies, technical coordination is transferred to a single non-governmental organization: the Internet Coordination of Assigned Numbers and Names. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Timeline Cryptography - Introduction Besides oral conversations and written language many other ways of information-transport are known: like the bush telegraph, drums, smoke signals etc. Those methods are not cryptography, still they need en- and decoding, which means that the history of language, the history of communication and the history of cryptography are closely connected to each other The timeline gives an insight into the endless fight between enciphering and deciphering. The reasons for them can be found in public and private issues at the same time, though mostly connected to military maneuvers and/or political tasks.

Acessing the Internet The Net connections can be based on wire-line and wireless access technolgies.
Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables Satellite communication Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks. Privatization of satellite communication Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as Scheduled privatization of intergovernmental satellite consortia:
When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers. As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost. Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

Copyright Management and Control Systems: Metering Hardware Devices Those have to be acquired and installed by the user. For example under a debit card approach, the user purchases a debit card that is pre-loaded with a certain amount of value. After installation, the debit card is debited automatically as the user consumes copyrighted works. Digital Certificates Hereby a certification authority issues to a user an electronic file that identifies the user as the owner of a public key. Those digital certificates, besides Centralized Computing Under this approach all of the executables remain at the server. Each time the executable is used, the user's computer must establish contact with the server, allowing the central computer to meter access. Access Codes Access code devices permit users to "unlock" protective mechanisms (e.g. date bombs or functional limitations) embedded in copyrighted works. Copyright owners can meter the usage of their works, either by unlocking the Copyright Clearinghouses Under this approach copyright owners would commission "clearinghouses" with the ability to license the use of their works. A user would pay a license fee to obtain rights concerning the intellectual property. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
