History: "Indigenous Tradition" In preliterate societies the association of rhythmic or repetitively patterned utterances with supernatural knowledge endures well into historic times. Knowledge is passed from one generation to another. Similar as in the Southern tradition |

Timeline of Communication Systems: Introduction The timeline of communication systems presents a chronological overview of the most important events in the history of communication systems from the 4th millennium B.C. to the present. It shows that from the very beginning - the first Sumerian pictographs on clay tablets to today's state-of-the-art technologies - broadband communication via |

History: European Tradition Only in Roman times the first rights referring to artistic works appeared. Regulations resembling a lasting exclusive right to copy did not occur until the 17th century. Before copyright was a private arrangement between guilds able to reproduce copies in commercial quantities. In France and Western European countries "droits d'auteur" or author's rights is the core of what in the Anglo-American tradition is called copyright. Such rights are rooted in the republican revolution of the late 18th century, and the Rights of Man movement. Today in the European system the creator is front and center; later exploiters are only secondary players. France During the 18th century France gradually lost the ability to restrict In 1777 the King threatened the monopoly by reducing the duration of publisher's privileges to the lifetime of the authors. Accordingly a writer's work would go into the public domain after his death and could be printed by anyone. The booksellers fought back by argumenting that, no authority could take their property from them and give it to someone else. Seven months later, in August 1789, the revolutionary government ended the privilege system and from that time on anyone could print anything. Early in 1790 Marie-Jean-Antoine-Nicolas de Caritat, Marquis de Condorcet proposed giving authors power over their own work lasting until ten years after their deaths. The proposal - the basis for France's first modern copyright law - passed in 1793. |

Intellectual Property: A Definition Intellectual property, very generally, relates to the output, which result from intellectual activity in the industrial, scientific, literary and artistic fields. Traditionally intellectual property is divided into two branches: 1) Industrial Property a) b) c) d) Unfair competition (trade secrets) e) Geographical indications (indications of source and appellations of origin) 2) Copyright The protection of intellectual property is guaranteed through a variety of laws, which grant the creators of intellectual goods, and services certain time-limited rights to control the use made of their products. Those rights apply to the intellectual creation as such, and not to the physical object in which the work may be embodied. |

Governmental Influence Agencies like the NSA are currently able to eavesdrop on anyone with few restrictions only - though other messages are spread by the NSA. Theoretically cryptography can make that difficult. Hence those agencies speak up for actions like introducing trapdoors to make it possible to get access to everybody's data. See the U.S. discussion about the Clipper Chip some years ago: While encryption offers us privacy for the transmission of data, we do not only wish to have it but also need it if we want to transport data which shall not be seen by anyone else but the recipient of our message. Given this, the governments and governmental institutions/organizations fear to lose control. Strict laws are the consequence. The often repeated rumor that the Internet was a sphere of illegality has been proven wrong. Some parts are controlled by law very clearly. One of them is cryptography. Prohibition of cryptography or at least its restriction are considered an appropriate tool against criminality. Or one should say: had been considered that. In the meantime also governmental institutions have to admit that those restrictions most of all work against the population instead against illegal actors. Therefore laws have been changed in many states during the last five years. Even the USA, the Master of cryptography-restriction, liberated its laws in December 1999 to be more open-minded now. for an insight into the discussion having gone on for years see: the final text of the new U.S. Encryption Regulations you will find under: an explanation of the regulations can be found under: |

Digital Signatures, Timestamps etc Most computer systems are far from being secure. A lack of security - it is said - might hinder the developments of new information technologies. Everybody knows electronic transactions involve a more or less calculated risk. Rumors about insecurity let consumers doubt whether the commodity of e-commerce is bigger or its risks. First of all the market depends on the consumer's confidence. To provide that another application for public key cryptography gets essential: the digital signature, which is used to verify the authenticity of the sender of certain data. It is done with a special private key, and the public key is verifying the signature. This is especially important if the involved parties do not know one another. The DSA (= Digital Signature Algorithm) is a public-key system which is only able to sign digitally, not to encrypt messages. In fact digital signature is the main-tool of cryptography in the private sector. Digital signatures need to be given for safe electronic payment. It is a way to protect the confidentiality of the sent data, which of course could be provided by other ways of cryptography as well. Other security methods in this respect are still in development, like digital money (similar to credit cards or checks) or digital cash, a system that wants to be anonymous like cash, an idea not favored by governments as it provides many opportunities for money laundry and illegal transactions. If intellectual property needs to be protected, a digital signature, together with a digital timestamp is regarded as an efficient tool. In this context, the difference between identification and authentication is essential. In this context smartcards and firewalls are relevant, too. A lot of digital transactions demand for passwords. More reliable for authentication are biometric identifiers, full of individual and unrepeatable codes, signatures that can hardly be forged. For more terms of cryptography and more information see: |
