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. |

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. |

RSA The best known of the two-key cryptosystems developed in the mid-1980s is the Rivest-Shamir-Adleman (RSA) cryptoalgorithm, which was first published in April, 1977. Since that time, the algorithm has been employed in the most widely-used Internet electronic communications encryption program, |

Galileo Galilee Galileo Galilee (1564-1642), the Italian Mathematician and Physicist is called the father of Enlightenment. He proofed the laws of the free fall, improved the technique for the telescope and so on. Galilee is still famous for his fights against the Catholic Church. He published his writings in Italian instead of writing in Latin. Like this, everybody could understand him, which made him popular. As he did not stop talking about the world as a ball (the Heliocentric World System) instead of a disk, the Inquisition put him on trial twice and forbid him to go on working on his experiments. |
