Operating the net: overview

The Net consists of thousands of thousands of governmental and private networks linked together. No legal authority determines how and where networks can be connected together, this is something the managers of networks have to agree about. So there is no way of ever gaining ultimate control of the Internet. Although each of these networks is operated and controlled by an organization, no single organization operates and controls the Net. Instead of a central authority governing the Net, several bodies assure the operability of the Net by developing and setting technical specifications for the Net and by the control of the technical key functions of the Net as the coordination of the domain name system and the allocation of IP numbers.

Originally, the Net was a research project funded and maintained by the US Government and developed in collaboration by scientists and engineers. As the standards developed for ensuring operability ensued from technical functionality, technical coordination gradually grew out of necessity and was restricted to a minimum and performed by volunteers.

Later, in the 1980s, those occupied with the development of technical specifications organized themselves under the umbrella of the Internet Society in virtual organizations as the Internet Engineering Task Force, which were neither officially established nor being based on other structures than mailing lists and commitment, but nonetheless still serve as task forces for the development of standards ensuring the interoperability on the Net.

Since the late 80s and the early 90s, with the enormous growth of the Net - which was promoted by the invention of Local Area Networks, the creation of the World Wide Web, the increased use of personal computers and the connecting of corporations to the Net, just to name a few - coordination of some technical key functions as the domain name system was handed over to corporations as Network Solutions Inc.

Since the year 2000, a new model for technical coordination has been emerging: Formerly performed by several bodies, technical coordination is transferred to a single non-governmental organization: the Internet Coordination of Assigned Numbers and Names.

Cryptography's Terms and background

"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)

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.

Steganography

Ciphers as well as codes are transmitted openly. Everyone can see that they exist. Not so with steganograms.
Steganography is the art and science of communicating in a way which hides the existence of the secret part in that communication. During the Italian Renaissance and the time of the Elizabethan Age in England cryptography was very popular, for political reasons as well as for amusements (see John Dee).
In literature steganography played an important role. Many steganographs of that period have only been deciphered recently like some of the Shakespearean sonnets, which now seem to proof that the actor William Shakespeare was not the author of the famous poems and dramas, but that the latter' name was, and Francis Bacon, or even Francis Tudor, as some ciphers and other sources talk of him as Queen Elisabeth I.'s secret son.

for further details see:
http://home.att.net/~tleary/
http://www.thur.de/ulf/stegano/
http://www2.prestel.co.uk/littleton/gm2_rw.htm

One kind of steganogram is digital watermarking:
Watermarks protect digital images, videos, but also audio and multimedia products. They are made out of digital signals, put into other digital signals. They try to be invisible on first sight and should be nearly impossible to remove. The process of producing watermarks is to overlay some sort of identifying image over the original image (non-digital watermarks, like on money can be seen by holding the paper against light). Copying the image destroys the watermark, which cannot be copied. Any alteration of the original destroys the watermark, too.

Watermarking is one of the typical inventions of cryptography to assist the biggest content owners, but advertised as something necessary and helpful for everybody. Who in fact gets any advantage out of watermarking? The private user most of the time will not really need it except for small entities of pictures maybe.
But the big enterprises do. There is a tendency to watermark more and more information in the Internet, which until now was considered as free and as a cheap method to receive information. Watermarking could stop this democratic development.

The Privatization of Censorship

According to a still widely held conviction, the global data networks constitute the long desired arena for uncensorable expression. This much is true: Because of the Net it has become increasingly difficult to sustain cultural and legal standards. Geographical proximity and territorial boundaries prove to be less relevant, when it does not affect a document's availability if it is stored on your desktop or on a host some thousand kilometers away. There is no international agreement on non-prohibited contents, so human rights organizations and nazi groups alike can bypass restrictions. No single authority or organization can impose its rules and standards on all others. This is why the Net is public space, a political arena where free expression is possible.

This freedom is conditioned by the design of the Net. But the Net's design is not a given, as Lawrence Lessig reminds us. Originally the design of the Net allowed a relatively high degree of privacy and communication was not controlled directly. But now this design is changing and this invisible agora in electronic space is endangered. Governments - even elected ones - and corporations introduce new technologies that allow us to be identified, monitored and tracked, that identify and block content, and that can allow our behaviour to be efficiently controlled.

When the World Wide Web was introduced, soon small independent media and human rights organizations began to use this platform for drawing worldwide attention to their publications and causes. It seemed to be the dawning of a new era with authoritarian regimes and multinational media corporations on the looser side. But now the Net's design is changing according to their needs.

"In every context that it can, the entertaining industry is trying to force the Internet into its own business model: the perfect control of content. From music (fighting MP3) and film (fighting the portability of DVD) to television, the industry is resisting the Net's original design. It was about the free flow of content; Hollywood wants perfect control instead" (Lawrence Lessig, Cyberspace Prosecutor, in: The Industry Standard, February 2000).

In the United States, Hollywood and AT&T, after its merger with MediaOne becoming the biggest US cable service provider, return to their prior positions in the Seventies: the control of content and infrastructure. If most people will access the Net via set up boxes connected to a TV set, it will become a kind of television, at least in the USA.

For small independent media it will become very hard to be heard, especially for those offering streaming video and music. Increasingly faster data transmissions just apply to download capacities; upload capacities are much - on the average about eight times - lower than download capacities. As an AT&T executive said in response to criticism: "We haven't built a 56 billion dollar cable network to have the blood sucked from our veins" (Lawrence Lessig, The Law in the Code: How the Net is Regulated, Lecture at the Institute for Human Sciences, Vienna, May 29th, 2000).

Consumers, not producers are preferred.

For corporations what remains to be done to control the Net is mainly to cope with the fact that because of the Net it has become increasingly difficult to sustain cultural and legal standards. On Nov 11, 1995 the German prosecuting attorney's office searched Compuserve Germany, the branch of an international Internet service provider, because the company was suspected of having offered access to child pornography. Consequently Compuserve blocked access to more than 200 newsgroups, all containing "sex" or "gay" in their names, for all its customers. But a few days later, an instruction for access to these blocked newsgroups via Compuserve came into circulation. On February 26, 1997, Felix Somm, the Chief Executive Officer of Compuserve Germany, was accused of complicity with the distribution of child and animal pornography in newsgroups. In May 1998 he received a prison sentence for two years. This sentence was suspended against a bail of about 51.000 Euro. The sentence was justified by pointing to the fact that Compuserve Germany offered access to its US parent company's servers hosting child pornography. Felix Somm was held responsible for access to forbidden content he could not know of. (For further information (in German) click here.)

Also in 1995, as an attack on US Vice-President Al Gore's intention to supply all public schools with Internet access, Republican Senator Charles Grassley warned of the lurking dangers for children on the Net. By referring to a Time magazine cover story by Philip Elmer-Dewitt from July 3 on pornography on the Net, he pointed out that 83,5% of all images online are pornographic. But Elmer-Dewitt was wrong. Obviously unaware of the difference between Bulletin Board Systems and the Net, he referred misleadingly to Marty Rimm's article Marketing Pornography on the Information Superhighway, published in the prestigious Georgetown Law Journal (vol. 83, June 1995, pp. 1849-1935). Rimm knew of this difference, of course, and stated it clearly. (For further information see Hoffman & Novak, The Cyberporn debate, http://ecommerce.vanderbilt.edu/cyberporn.debate.html and Franz Wegener, Cyberpornographie: Chronologie einer Hexenjagd; http://www.intro-online.de/c6.html)

Almost inevitably anxieties accompany the introduction of new technologies. In the 19th century it was said that traveling by train is bad for health. The debate produced by Time magazine's cover story and Senator Grassley's attack caused the impression that the Net has multiplied possible dangers for children. The global communication networks seem to be a inexhaustible source of mushrooming child pornography. Later would-be bomb recipes found on the Net added to already prevailing anxieties. As even in industrialized countries most people still have little or no first-hand experience with the Net, anxieties about child pornography or terrorist attacks can be stirred up and employed easily.

A similar and related debate is going on about the glorification of violence and erotic depictions in media. Pointing to a "toxic popular culture" shaped by media that "distort children's view of reality and even undermine their character growth", US right-wing social welfare organizations and think tanks call for strong media censorship. (See An Appeal to Hollywood, http://www.media-appeal.org/appeal.htm) Media, especially films and videos, are already censored and rated, so it is more censorship that is wanted.

The intentions for stimulating a debate on child pornography on the Net were manifold: Inter alia, it served the Republican Party to attack Democrat Al Gore's initiative to supply all public schools with Internet access; additionally, the big media corporations realized that because of the Net they might have to face new competitors and rushed to press for content regulation. Taking all these intentions together, we can say that this still ongoing debate constitutes the first and most well known attempt to impose content regulation on the Net. Consequently, at least in Western countries, governments and media corporations refer to child pornography for justifying legal requirement and the implementation of technologies for the surveillance and monitoring of individuals, the filtering, rating and blocking of content, and the prohibition of anonymous publishing on the Net.

In the name of "cleaning" the Net of child pornography, our basic rights are restricted. It is the insistence on unrestricted basic rights that needs to be justified, as it may seem.

Underlying the campaign to control the Net are several assumptions. Inter alia: The Net lacks control and needs to be made safe and secure; we may be exposed inadvertently to pornographic content; this content is harmful to children. Remarkably, racism seems to be not an issue.

The Net, especially the World Wide Web, is not like television (although it is to be feared this is what it might become like within the next years). Say, little Mary types "Barbie" in a search engine. Click here to see what happens. It is true, sometimes you might have the opportunity to see that pornography is just a few mouse clicks away, but it is not likely that you might be exposed to pornographic content unless you make deliberate mouse clicks.

In reaction to these anxieties, but in absence of data how children use the Internet, the US government released the Communications Decency Act (CDA) in 1996. In consequence the Electronic Frontier Foundation (EFF) launched the famous Blue Ribbon Campaign and, among others, America Online and Microsoft Corporation supported a lawsuit of the American Civil Liberties Union (ACLU) against this Act. On June 26, 1997, the US Supreme Court ruled the CDA as unconstitutional under the provisions of the First Amendment to the Constitution: The Communications Decency Act violated the basic right to free expression. After a summit with the US government industry leaders announced the using of existing rating and blocking systems and the development of new ones for "inappropriate" online resources.

So, after the failing of the CDA the US government has shifted its responsibility to the industry by inviting corporations to taking on governmental tasks. Bearing in the mind the CompuServe case and its possible consequences, the industry welcomed this decision and was quick to call this newly assumed responsibility "self-regulation". Strictly speaking, "self-regulation" as meant by the industry does not amount to the regulation of the behaviour of corporations by themselves. On the opposite, "self-regulation" is to be understood as the regulation of users' behaviour by the rating, filtering and blocking of Internet content considered being inappropriate. The Internet industry tries to show that technical solutions are more favourable than legislation und wants to be sure, not being held responsible and liable for illegal, offensive or harmful content. A new CompuServe case and a new Communications Decency Act shall be averted.

In the Memorandum Self-regulation of Internet Content released in late 1999 by the Bertelsmann Foundation it is recommended that the Internet industry joins forces with governmental institutions for enforcing codes of conduct and encouraging the implementation of filters and ratings systems. For further details on the Memorandum see the study by the Center for Democracy and Technology, An Analysis of the Bertelsmann Foundation Memorandum on Self-Regulation of Internet Content: Concerns from a User Empowerment Perspective.

In fact, the "self-regulation" of the Internet industry is privatized censorship performed by corporations and right-wing NGOs. Censorship has become a business. "Crucially, the lifting of restrictions on market competition hasn't advanced the cause of freedom of expression at all. On the contrary, the privatisation of cyberspace seems to be taking place alongside the introduction of heavy censorship." (Richard Barbrook and Andy Cameron, The Californian Ideology)

While trying to convince us that its technical solutions are appropriate alternatives to government regulation, the Internet industry cannot dispense of governmental backing to enforce the proposed measures. This adds to and enforces the censorship measures already undertaken by governments. We are encouraged to use today's information and communication technologies, while the flow of information is restricted.

According to a report by Reporters Sans Frontières, quoted by Leonard R. Sussman in his essay Censor Dot Gov. The Internet and Press Freedom 2000, the following countries totally or largely control Internet access: Azerbaijan, Belarus, Burma, China, Cuba, Iran, Iraq, Kazakhstan, Kirghizstan, Libya, North Korea, Saudi Arabia, Sierra Leone, Sudan, Syria, Tajikistan, Tunisia, Turkmenistan, Uzbekistan, and Vietnam.

Internet Advertising

The advertising industry has always relied on media to transport their messages and disseminate them to the public. Depending on the product or service advertised and the audience targeted different media are used. Besides cinema and outdoor advertising (posters etc.) the huge majority of ads is placed within the classical media landscape, which includes TV, newspapers, magazines and radio.

Whereas in most cases only a relatively small fraction of advertising budgets is spent on cinema, outdoor and radio advertising, newspapers, magazines and TV account for more than two thirds of the money spent on ads. Still with the growing popularity of new media advertisers and marketers have recently also discovered digital networks and especially the Internet for their purposes.

Definition

During the last 20 years the old Immanuel Wallerstein-paradigm of center - periphery and semi-periphery found a new costume: ICTs. After Colonialism, Neo-Colonialism and Neoliberalism a new method of marginalization is emerging: the digital divide.

"Digital divide" describes the fact that the world can be divided into people who
do and people who do not have access to (or the education to handle with) modern information technologies, e.g. cellular telephone, television, Internet. This digital divide is concerning people all over the world, but as usually most of all people in the formerly so called third world countries and in rural areas suffer; the poor and less-educated suffer from that divide.
More than 80% of all computers with access to the Internet are situated in larger cities.

"The cost of the information today consists not so much of the creation of content, which should be the real value, but of the storage and efficient delivery of information, that is in essence the cost of paper, printing, transporting, warehousing and other physical distribution means, plus the cost of the personnel manpower needed to run these `extra' services ....Realizing an autonomous distributed networked society, which is the real essence of the Internet, will be the most critical issue for the success of the information and communication revolution of the coming century of millennium."
(Izumi Aizi)

biotechnology introduction



One of the most critical trends in the western culture what might be called the "fusion of flesh and machine". Increasingly, technological artifacts such as computers, rather than being used as tools by people, are functioning as parts of the human organism. On the other hand, human functionalities such as intelligence, emotion, adaptability or reproductivity are integrated into technological artifacts: the days when computers where only able to count apples and pears and their intelligence was not even matching an insect's are rapidly becoming history. Today, the boundaries between organisms and technology are losing their significance.

As new technologies are no longer mere instruments, or "extensions" of the organism, they acquire the capability of modifying the human organism - body and mind - from within according to certain pre-established principles. The history of the evolution of the human species is hastily being re-written as artificial beings begin to mock the categories of evolution and seem to work their way towards historical subjectivity. The German philosopher Günther Anders has extensively reflected on the changes of the human condition provoked by the development of modern technology speaks of an "antiquatedness of history" at a time when technology itself becomes a historical subject and men are becoming co-historical.

However, the softening of the biological definition of the human race is a theme which has accompanied western thinking ever since its origins. Beings half man-half animal crowd the tales of classical mythology and transcend the boundary between the human from below, while divine creatures, temporarily occupying humanoid bodies, relativise humanness form "above". What exactly "being human" meant and who "human beings" could be "defined" is a question with a long history. "Der Mensch ist das nicht festgestellte Thier" as Nietzsche commented.

Just as the boundaries between human and non-human are being crossed by technological development, so also the boundaries between the classical episteme are becoming permeable. Psychology is occupying itself with the emotions of machines, while physics and cybernetics is applied to the human mind and body. The "nicht festgestellte "character of humanness has meant that imagination has become just as relevant a factor in understanding humanness as science. Science fiction as a literary genre is no longer merely a depository of phantasies about a technisised world our of control. As the human monopoly on history seems to dissolve, the baroque narratives of science fiction have also become a resource for understanding history.

However, it is evident that the potentials of the new technologies gives rise not only to wild hopes and dreams and to bizarre stories; they also harbour some real ambiguities of a political and ethical nature. Not only does the merging of previously distinct realities - the human and the non-human worlds - unhinge theories and institutions based upon a clear distinction and separation of the two, it also is placing political practice on a different footing. Will artificial life have rights? Will artificial entities have political power? How will social relationships change?

Intelsat

Intelsat, the world's biggest communication satellite services provider, is still mainly owned by governments, but will be privatised during 2001, like Eutelsat. A measure already discussed 1996 at an OECD competition policy roundtable in 1996. Signatory of the Intelsat treaty for the United States of America is Comsat, a private company listed on the New York Stock Exchange. Additionally Comsat is one of the United Kingdom's signatories. Aggregated, Comsat owns about 20,5% of Intelsat already and is Intelsat's biggest shareholder. In September 1998 Comsat agreed to merge with Lockheed Martin. After the merger, Lockheed Martin will hold at least 49% of Comsat share capital.

Fiber-optic cable networks

Fiber-optic cable networks may become the dominant method for high-speed Internet connections. Since the first fiber-optic cable was laid across the Atlantic in 1988, the demand for faster Internet connections is growing, fuelled by the growing network traffic, partly due to increasing implementation of corporate networks spanning the globe and to the use of graphics-heavy contents on the World Wide Web.

Fiber-optic cables have not much more in common with copper wires than the capacity to transmit information. As copper wires, they can be terrestrial and submarine connections, but they allow much higher transmission rates. Copper wires allow 32 telephone calls at the same time, but fiber-optic cable can carry 40,000 calls at the same time. A capacity, Alexander Graham Bell might have not envisioned when he transmitted the first words - "Mr. Watson, come here. I want you" - over a copper wire.

Copper wires will not come out of use in the foreseeable future because of technologies as DSL that speed up access drastically. But with the technology to transmit signals at more than one wavelength on fiber-optic cables, there bandwidth is increasing, too.
