Gutenberg's printing press was an innovative aggregation of inventions known for centuries before Gutenberg: the olive oil press, oil-based ink, block-print technology, and movable types allowed the mass production of the movable type used to reproduce a page of text and enormously increased the production rate. During the Middle Ages it took monks at least a year to make a handwritten copy of a book. Gutenberg could print about 300 sheets per day. Because parchment was too costly for mass production - for the production of one copy of a medieval book often a whole flock of sheep was used - it was substituted by cheap paper made from recycled clothing of the massive number of deads caused by the Great Plague.
Within forty-five years, in 1500, ten million copies were available for a few hundred thousand literate people. Because individuals could examine a range of opinions now, the printed Bible - especially after having been translated into German by Martin Luther - and increasing literacy added to the subversion of clerical authorities. The interest in books grew with the rise of vernacular, non-Latin literary texts, beginning with Dante's Divine Comedy, the first literary text written in Italian.
Among others the improvement of the distribution and production of books as well as increased literacy made the development of print mass media possible.
Michael Giesecke (Sinnenwandel Sprachwandel Kulturwandel. Studien zur Vorgeschichte der Informationsgesellschaft, Frankfurt am Main: Suhrkamp, 1992) has shown that due to a division of labor among authors, printers and typesetters Gutenberg's invention increasingly led to a standardization of - written and unwritten - language in form of orthography, grammar and signs. To communicate one's ideas became linked to the use of a code, and reading became a kind of rite of passage, an important step towards independency in a human's life.
With the growing linkage of knowledge to reading and learning, the history of knowledge becomes the history of reading, of reading dependent on chance and circumstance.

- Concerning their human and financial resources commercial media and independent content provider are an extremely unequal pair. While the 1998 revenues of the world's leading media conglomerates (AOL Time Warner, Disney, Bertelsmann, Viacom and the News Corporation) amounted to US$ 91,144,000,000 provider of independent content usually act on a non-profit basis and to a considerable extent depend on donations and contributions.
Also the human resources they have at their disposal quite differ. Viacom for example employs 112,000 people. Alternative media conversely are mostly run by a small group of activists, most of them volunteers. Moreover the majority of the commercial media giants has a multitude of subsidiaries (Bertelsmann for instance has operations in 53 countries), while independent content provider in some cases do not even have proper office spaces. Asked about their offices number of square meters Frank Guerrero from RTMark comments "We have no square meters at all, because we are only on the web. I guess if you add up all of our servers and computers we would take up about one or two square meters."

As scientists are working hard on a quantum computer and also on quantum cryptography one can imagine that another revolution in the study of encryption has to be expected within the next years. By then today's hardware and software tools will look extraordinary dull. At the moment it is impossible to foresee the effects on cryptography and democratic developments by those means; the best and the worst can be expected at the same time. A certain ration of pessimism and prosecution mania are probably the right mixture of emotions about those tendencies, as the idea of big brother has come into existence long ago.
At the same time it will - in part - be a decision of the people to let science work against them or not. Acceleration of data-transmission calls for an acceleration of encryption-methods. And this again falls back on us, on an acceleration of daily life, blurring the private and the public for another time.
We live in an intersection, job and private life growing together. Cryptography cannot help us in that case. The privacy in our mind, the virtuality of all private and public lies in the field of democracy, or at least what is - by connection to the Human Rights - regarded as democracy.

IDEA is another symmetric-key system. It is a block cipher, operating on 64-bit plaintext blocks, having a key-length of 128 bits.
The MIT (Massachusetts Institute of Technology) is a privately controlled coeducational institution of higher learning famous for its scientific and technological training and research. It was chartered by the state of Massachusetts in 1861 and became a land-grant college in 1863. During the 1930s and 1940s the institute evolved from a well-regarded technical school into an internationally known center for scientific and technical research. In the days of the Great Depression, its faculty established prominent research centers in a number of fields, most notably analog computing (led by
Blowfish is a symmetric key block cipher that can vary its length.
The idea behind is a simple design to make the system faster than others.
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..." (
