Internet, Intranets, Extranets, and Virtual Private Networks

With the rise of networks and the corresponding decline of mainframe services computers have become communication devices instead of being solely computational or typewriter-like devices. Corporate networks become increasingly important and often use the Internet as a public service network to interconnect. Sometimes they are proprietary networks.

Software companies, consulting agencies, and journalists serving their interests make some further differences by splitting up the easily understandable term "proprietary networks" into terms to be explained and speak of Intranets, Extranets, and Virtual Private Networks.

Cable TV networks and online services as Europe Online, America Online, and Microsoft Network are also proprietary networks. Although their services resemble Internet services, they offer an alternative telecommunication infrastructure with access to Internet services for their subscribers.
America Online is selling its service under the slogan "We organize the Web for you!" Such promises are more frightening than promising because "organizing" is increasingly equated with "filtering" of seemingly objectionable messages and "rating" of content. For more information on these issues, click here If you want to know more about the technical nature of computer networks, here is a link to the corresponding article in the Encyclopaedia Britannica.

Especially for financial transactions, secure proprietary networks become increasingly important. When you transfer funds from your banking account to an account in another country, it is done through the SWIFT network, the network of the Society for Worldwide Interbank Financial Telecommunication (SWIFT). According to SWIFT, in 1998 the average daily value of payments messages was estimated to be above U$ 2 trillion.

Electronic Communications Networks as Instinet force stock exchanges to redefine their positions in trading of equities. They offer faster trading at reduced costs and better prices on trades for brokers and institutional investors as mutual funds and pension funds. Last, but not least clients are not restricted to trading hours and can trade anonymously and directly, thereby bypassing stock exchanges.

Another Question of Security

Even with the best techniques it is impossible to invent a cryptographic system that is absolutely safe/unbreakable. To decipher a text means to go through many, sometimes nearly - but never really - endless attempts. For the computers of today it might take hundreds of years or even more to go through all possibilities of codes, but still, finally the code stays breakable. The much faster quantum computers will proof that one day.
Therefore the decision to elect a certain method of enciphering finally is a matter of trust.

For the average user of computers it is rather difficult to understand or even realize the dangers and/or the technological background of electronic transmission of data. For the majority thinking about one's own necessities for encryption first of all means to trust others, the specialists, to rely on the information they provide.
The websites explaining the problems behind (and also the articles and books concerning the topic) are written by experts of course as well, very often in their typical scientific language, merely understandable for laymen. The introductions and other superficial elements of those articles can be understood, whereas the real background appears as untouchable spheres of knowledge.

The fact that dangers are hard to see through and the need for security measures appears as something most people know from media reports, leads directly to the problem of an underdeveloped democracy in the field of cryptography. Obviously the connection between cryptography and democracy is rather invisible for many people. Those mentioned media reports often specialize in talking about the work computer hackers do (sometimes being presented as criminals, sometimes as heroes) and the danger to lose control over the money drawn away from one's bank account, if someone steals the credit card number or other important financial data. The term "security", surely connected to those issues, is a completely different one from the one that is connected to privacy.
It is especially the latter that touches the main elements of democracy.

Adolf Hitler

Adolf Hitler (1889-1945) was the head of the NSdAP, the National Socialist Workers' Party. Originally coming from Austria, he started his political career in Germany. As the Reichskanzler of Germany he provoked World War II. His hatred against all non-Aryans and people thinking in a different way killed millions of human beings. Disinformation about his personality and an unbelievable machinery of propaganda made an entire people close its eyes to the most cruel crimes on human kind.

1996 WIPO Copyright Treaty (WCT)

The 1996 WIPO Copyright Treaty, which focused on taking steps to protect copyright "in the digital age" among other provisions 1) makes clear that computer programs are protected as literary works, 2) the contracting parties must protect databases that constitute intellectual creations, 3) affords authors with the new right of making their works "available to the public", 4) gives authors the exclusive right to authorize "any communication to the public of their works, by wire or wireless means ... in such a way that members of the public may access these works from a place and at a time individually chosen by them." and 5) requires the contracting states to protect anti-copying technology and copyright management information that is embedded in any work covered by the treaty. The WCT is available on: http://www.wipo.int/documents/en/diplconf/distrib/94dc.htm
