This is the largest area of application of biometric technologies, and the most direct lineage to the feudal gate keeping system. Initially mainly used in military and other "high security" territories, physical access control by biometric technology is spreading into a much wider field of application. Biometric access control technologies are already being used in schools, supermarkets, hospitals and commercial centres, where the are used to manage the flow of personnel.
Biometric technologies are also used to control access to political territory, as in immigration (airports, Mexico-USA border crossing). In this case, they can be coupled with camera surveillance systems and artificial intelligence in order to identify potential suspects at unmanned border crossings. Examples of such uses in remote video inspection systems can be found at

An electronic reconstruction of feudal gate keeping capable of singling out high-risk travellers from the rest is already applied at various border crossing points in the USA. "All enrolees are compared against national lookout databases on a daily basis to ensure that individuals remain low risk". As a side benefit, the economy of time generated by the inspection system has meant that "drug seizures ... have increased since Inspectors are able to spend more time evaluating higher risk vehicles".
However, biometric access control can not only prevent people from gaining access on to a territory or building, they can also prevent them from getting out of buildings, as in the

Following the communist revolutions of the 20th century all "means of production" became the property of the state as representative of "the masses". Private property ceased to exist. While moral rights of the creator were recognized and economic rights acknowledged with a one-time cash award, all subsequent rights reverted to the state.
With the transformation of many communist countries to a market system most of them have now introduced laws establishing markets in intellectual property rights. Still the high rate of piracy reflects a certain lack of legal tradition.

With the dissemination of their content commercial media are among other things also able to transport values and ideologies. Usually their programming reflects society's dominant social, political, ethical, cultural and economical values. A critical view of the prevalent ideologies often is sacrificed so as not to offend the existing political elites and corporate powers, but rather satisfy shareholders and advertisers.
With most of the worlds content produced by a few commercial media conglomerates, with the overwhelming majority of companies (in terms of revenue generation) concentrated in Europe, the U.S., Japan and Australia there is also a strong flow of content from the 'North-West' to the 'South-East'. Popular culture developed in the world's dominant commercial centers and Western values and ideologies are so disseminated into the most distant corners of the earth with far less coming back.

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
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,
In the United States, Hollywood and
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" (
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
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
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,
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
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
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
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." (
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.

Art has always contributed a lot to disinformation.
Many modern tools for disinformation are used in art/photography.
Trillions of photographs have been taken in the 20th century. Too many to look at, too many to control them and their use. A paradise for manipulation.
We have to keep in mind: There is the world, and there exist pictures of the world, which does not mean that both are the same thing. Photographs are not objective, because the photographer selects the part of the world which is becoming a picture. The rest is left out.
Some tools for manipulation of photography are:
morphing (71)
wet operation (73)
neutralizing (74)
masks (75)
damnatio memoriae (78)
Some of those are digital ways of manipulation, which helps to change pictures in many ways without showing the manipulation.
Pictures taken from the internet could be anything and come from anywhere. To proof the source is nearly impossible. Therefore scientists created on watermarks for pictures, which make it impossible to "steal" or manipulate a picture out of the net.

Global networks require global technical standards ensuring the compatibility of systems. Being able to define such standards makes a corporation extremely powerful. And it requires the suspension of competitive practices. Competition is relegated to the symbolic realm. Diversity and pluralism become the victims of the globalisation of baroque sameness.
The ICT market is dominated by incomplete competition aimed at short-term market domination. In a very short time, new ideas can turn into best-selling technologies. Innovation cycles are extremely short. But today's state-of-the-art products are embryonic trash.

The Internet/Matrix still depends heavily on public infrastructure and there is no dedicated owner of the whole Internet/Matrix, but the networks it consists of are run and owned by corporations and institutions. Access to the Internet is usually provided by Internet Service Providers (ISPs) for a monthly fee. Each network is owned by someone and has a network operation center from where it is centrally controlled, but the Internet/Matrix is not owned by any single authority and has no network operation center of its own. 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 to ever gain ultimate control of the Matrix/Internet.

Never before propaganda had been as important as in the 2nd World War. From now on education was one more field of propaganda: its purpose was to teach how to think, while pure propaganda was supposed to show what to think.
Every nation founded at least one ministry of propaganda - of course without calling it that way. For example the British called it the Ministry of Information (= MOI), the U.S. distinguished between the Office of Strategic Services (= OSS) and the Office of War Information (= OWI), the Germans created a Ministry of Propaganda and Public Enlightenment (= RMVP) and the Japanese called their disinformation and propaganda campaign the "Thought War".

It has become a commonplace observation that the history of modernity has been accompanied by what one might call a general weakening of identity, both as a theoretical concept and as a social and cultural reality. This blurring of identity has come to full fruition in the 20th century. As a theoretical concept, identity has lost its metaphysical foundation of "full correspondence" following the destruction of metaphysics by thinkers such as Nietzsche, Heidegger, Witgenstein or Davidson. Nietzsche's "dead god", his often-quoted metaphor for the demise of metaphysics, has left western cultures not only with the problem of having to learn how to think without permanent foundations; it has left them with both the liberty of constructing identities, and the structural obligation to do so. The dilemmas arising out of this ambivalent situation have given rise to the comment that "god is dead, and men is not doing so well himself". The new promise of freedom is accompanied by the threat of enslavement. Modern, technologically saturated cultures survive and propagate and emancipate themselves by acting as the gatekeepers of their own technological prisons.
On the social and cultural levels, traditional clear-cut identities have become weakened as traditional cultural belonging has been undermined or supplanted by modern socio-technological structures. The question as to "who one is" has become increasingly difficult to answer: hybrid identities are spreading, identities are multiple, temporary, fleeting rather than reflecting an inherited sense of belonging. The war cry of modern culture industry "be yourself" demands the impossible and offers a myriad of tools all outcompeting each other in their promise to fulfil the impossible.
For many, identity has become a matter of choice rather than of cultural or biological heritage, although being able to chose may not have been the result of a choice. A large superstructure of purchasable identification objects caters for an audience finding itself propelled into an ever accelerating and vertiginous spiral of identification and estrangement. In the supermarket of identities, what is useful and cool today is the waste of tomorrow. What is offered as the latest advance in helping you to "be yourself" is as ephemeral as your identification with it; it is trash in embryonic form.
Identity has become both problematic and trivial, causing modern subjects a sense of thrownness and uprootedness as well as granting them the opportunity of overcoming established authoritarian structures. In modern, technologically saturated societies, the general weakening of identities is a prerequisite for emancipation. The return to "strong" clear-cut "real" identities is the way of new fundamentalism demanding a rehabilitation of "traditional values" and protected zones for metaphysical thought, both of which are to be had only at the price of suppression and violence.
It has become difficult to know "who one is", but this difficulty is not merely a private problem. It is also a problem for the exercise of power, for the state and other power institutions also need to know "who you are". With the spread of weak identities, power is exercised in a different manner. Power cannot be exercised without being clear who it addresses; note the dual significance of "subject". A weakened, hybrid undefined subject (in the philosophical sense) cannot be a "good" subject (in the political sense), it is not easy to sub-ject. Without identification, power cannot be exercised. And while identification is itself not a sufficient precondition for authoritarianism, it is certainly a necessary one.
Identities are therefore reconstructed using technologies of identification in order to keep the weakened and hence evasive subjects "sub-jected". States have traditionally employed bureaucratic identification techniques and sanctioned those who trying to evade the grip of administration. Carrying several passports has been the privilege of spies and of dubious outlaws, and not possessing an "ID" at all is the fate of millions of refugees fleeing violence or economic destitution. Lack of identification is structurally sanctioned by placelessness.
The technisised acceleration of societies and the weakening of identities make identification a complicated matter. On the one hand, bureaucratic identification techniques can be technologically bypassed. Passports and signatures can be forged; data can be manipulated and played with. On the other hand, traditional bureaucratic methods are slow. The requirements resulting from these constraints are met by biometric technology.

The big hope of the South is that the Internet will close the education gap and economic gap, by making education easier to achieve.
