late 1920's/30's more and more it is criminals who use cryptology for their purposes (e.g. for smuggling). Elizabeth Smith Friedman deciphers the codes of rum-smugglers during prohibition regularly
1929 Lester S. Hill publishes his book Cryptography in an Algebraic Alphabet, which contains enciphered parts
1933-1945 the Germans make the Enigma machine its cryptographic main-tool, which is broken by the Poles Marian Rejewski, Gordon Welchman and Alan Turing's team at Bletchley Park in England in 1939
1937 the Japanese invent their so called Purple machine with the help of Herbert O. Yardley. The machine works with telephone stepping relays. It is broken by a team of
1930's the Sigaba machine is invented in the USA, either by W.F. Friedman or his colleague Frank Rowlett
- at the same time the British develop the Typex machine, similar to the German Enigma machine
1943 Colossus, a code breaking computer is put into action at Bletchley Park
1943-1980 the cryptographic Venona Project, done by the NSA, is taking place for a longer period than any other program of that type
1948 Shannon, one of the first modern cryptographers bringing mathematics into cryptography, publishes his book A Communications Theory of Secrecy Systems

Personal data are collected, appropriated, processed and used for commercial purposes on a global scale. In order for such a global system to operate smoothly, there a server nodes at which the data streams converge. Among the foremost of these are the data bases of credit card companies, whose operation has long depended on global networking.
On top of credit card companies such as Visa, American Express, Master Card, and others. It would be erroneous to believe that the primary purpose of business of these companies is the provision of credit, and the facilitation of credit information for sale transactions. In fact, Information means much more than just credit information. In an advertisement of 1982, American Express described itself in these terms: ""Our product is information ...Information that charges airline tickets, hotel rooms, dining out, the newest fashions ...information that grows money funds buys and sells equities ...information that pays life insurance annuities ...information that schedules entertainment on cable television and electronically guards houses ...information that changes kroners into guilders and figures tax rates in Bermuda ..."
Information has become something like the gospel of the New Economy, a doctrine of salvation - the life blood of society, as Bill Gates expresses it. But behind information there are always data that need to be generated and collected. Because of the critical importance of data to the economy, their possession amounts to power and their loss can cause tremendous damage. The data industry therefore locates its data warehouses behind fortifications that bar physical or electronic access. Such structures are somewhat like a digital reconstruction of the medieval fortress
Large amounts of data are concentrated in fortress-like structures, in data bunkers. As the

Probably the most significant Internet service, the World Wide Web is not the essence of the Internet, but a subset of it. It is constituted by documents that are linked together in a way you can switch from one document to another by simply clicking on the link connecting these documents. This is made possible by the Hypertext Mark-up Language (HTML), the authoring language used in creating World Wide Web-based documents. These so-called hypertexts can combine text documents, graphics, videos, sounds, and
Especially on the World Wide Web, documents are often retrieved by entering keywords into so-called search engines, sets of programs that fetch documents from as many
Among other things that is the reason why the World Wide Web is not simply a very huge database, as is sometimes said, because it lacks consistency. There is virtually almost infinite storage capacity on the Internet, that is true, a capacity, which might become an almost everlasting too, a prospect, which is sometimes
According to the Internet domain survey of the
A mark (trademark or service mark) is "... a sign, or a combination of signs, capable of distinguishing the goods or services of one undertaking from those of other undertakings. The sign may particularly consist of one or more distinctive words, letters, numbers, drawings or pictures, emblems, colors or combinations of colors, or may be three-dimensional..." (
