- 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."

Although the traditional media companies first steps into the digital sphere were fairly clumsy, they have quickly learned from their mistakes and continued to enlarge their Internet presence.
During the last years many of the smaller players in the field of digital media have been driven out of competition by the huge media conglomerates. This mainly is a result of the advantages that the commercial media giants have over their less powerful counterparts:
- As engagement in online activities mostly does not lead to quick profits, investors must be able to take losses, which only powerful companies are able to.
- Traditional media outlets usually have huge stocks of digital programming, which they can easily plug into the Internet at little extra cost.
- To generate audience, the big media conglomerates constantly promote their Websites and other digital media products on their traditional media holdings.
- As possessors of the hottest "brands" commercial media companies often get premier locations from browser software makers, Internet service providers, search engines and portals.
- Having the financial resources at their disposition the big media firms are aggressive investors in start-up Internet media companies.
Commercial media companies have close and long ties to advertisers, which enables them to seize most of these revenues.

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.

In 1714 Henry Mill got granted a patent for his idea of an "artificial machine or method" for forgery-proof writing. Still it was not before 1808 that the first typewriter proven to have worked was built by Pellegrino Turri for his visually impaired friend, the Countess Carolina Fantoni da Fivizzono. The commercial production of typewriters began in 1873.

Searching for the Balduinist fluorescenting phosphor (Balduinischer Leuchtphosphor), an artificial fluorescent, Johann Heinrich Schulze realized the first photocopies, but did not put them into practical use.
The first optical photocopier was not patented before 1843, when William Henry Fox Talbot got granted a patent for his magnifying apparatus.
In 1847 Frederick Collier Bakewell developed a procedure for telecopying, a forerunner of the fax machine. Yet it was not before 1902 that images could be transmitted. Almost 200 years after Schulze's discovery, for the first time photo telegraphy was offered as a telecommunication service in Germany in 1922.
1794
Claude Chappe built a fixed optical network between Paris and Lille. Covering a distance of about 240kms, it consisted of fifteen towers with semaphores.
Because the communication system was designed for practical military use, the transmitted messages were encoded. The messages were kept such a secret that even those who transmit them from tower to tower did not capture their meaning; they transmitted codes they did not understand. Depending on weather conditions, messages could be sent at a speed of 2880 kms/hr at best.
Forerunners of Chappe's optical network are the

"All nature is merely a cipher and a secret writing."
Blaise de Vigenère
In the (dis-)information age getting information but at the same time excluding others from it is part of a power-game (keeping the other uneducated). The reason for it eventually has found an argument called security.
Compared to the frequency of its presence in articles, the news and political speeches security seems to be one of the most popular words of the 90's. It must be a long time ago when that word was only used for and by the military and the police. Today one can find it as part of every political issue. Even development assistance and nutrition programs consider it part of its work.
The so-called but also real need for information security is widespread and concerning everybody, whether someone uses information technology or not. In any case information about individuals is moving globally; mostly sensitive information like about bank records, insurance and medical data, credit card transactions, and much much more. Any kind of personal or business communication, including telephone conversations, fax messages, and of course e-mail is concerned. Not to forget further financial transactions and business information. Almost every aspect of modern life is affected.
We want to communicate with everybody - but do not want anybody to know.
Whereas the market already depends on the electronic flow of information and the digital tools get faster and more sophisticated all the time, the rise of privacy and security concerns have to be stated as well.
With the increase of digital communication its vulnerability is increasing just as fast. And there exist two (or three) elements competing and giving the term digital security a rather drastic bitter taste: this is on the one hand the growing possibility for criminals to use modern technology not only to hide their source and work secretly but also to manipulate financial and other transfers. On the other hand there are the governments of many states telling the population that they need access to any kind of data to keep control against those criminals. And finally there are those people, living between enlightening security gaps and at the same time harming other private people's actions with their work: computer hackers.
While the potential of global information is regarded as endless, it is those elements that reduce it.
There is no definite solution, but at least some tools have been developed to improve the situation: cryptography, the freedom to encode those data that one does not want to be known by everybody, and give a possibility to decode them to those who shall know the data.
During the last 80 years cryptography has changed from a mere political into a private, economic but still political tool: at the same time it was necessary to improve the tools, eventually based on mathematics. Hence generally cryptography is regarded as something very complicated. And in many ways this is true as the modern ways of enciphering are all about mathematics.
"Crypto is not mathematics, but crypto can be highly mathematical, crypto can use mathematics, but good crypto can be done without a great reliance on complex mathematics." (W.T. Shaw)
For an introduction into cryptography and the mathematical tasks see:

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.

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
