In what follows there is a brief description of the principal biometric technologies, whose respective proponents - producers, research laboratories, think tanks - mostly tend to claim superiority over the others. A frequently used definition of "biometric" is that of a "unique, measurable characteristic or trait of a human being for automatically recognizing or verifying identity" (
All biometric technologies are made up of the same basic processes:
1. A sample of a biometric is first collected, then transformed into digital information and stored as the "biometric template" of the person in question.
2. At every new identification, a second sample is collected and its identity with the first one is examined.
3. If the two samples are identical, the persons identity is confirmed, i.e. the system knows who the person is.
This means that access to the facility or resource can be granted or denied. It also means that information about the persons behaviour and movements has been collected. The system now knows who passed a certain identification point at which time, at what distance from the previous time, and it can combine these data with others, thereby appropriating an individual's data body.

In order to be able to recognize a person, one commonly looks at this persons face, for it is there where the visual features which distinguish one person from another are concentrated. Eyes in particular seem to tell a story not only about who somebody is, but also about how that persons feel, where his / her attention is directed, etc. People who do not want to show who they are or what is going on inside of them must mask themselves. Consequently, face recognition is a kind of electronic unmasking.
"Real" face-to-face communication is a two-way process. Looking at somebody's face means exposing ones own face and allowing the other to look at oneself. It is a mutual process which is only suspended in extraordinary and voyeuristic situations. Looking at somebody without being looked at places the person who is visually exposed in a vulnerable position vis-à-vis the watcher.
In face recognition this extraordinary situation is normal. Looking at the machine, you only see yourself looking at the machine. Face biometrics are extracted anonymously and painlessly by a mask without a face.
Therefore the resistance against the mass appropriation of biometrical data through surveillance cameras is confronted with particular difficulties. The surveillance structure is largely invisible, it is not evident what the function of a particular camera is, nor whether it is connected to a face recognition system.

The fact that an individual's identity is expressed not only by the way he/she looks or sounds, but also by the manner of walking is a relatively new discovery of in biometrics.
Unlike the more fully developed biometric technologies whose scrutiny is directed at stationary parts of the body, gait recognition has the added difficulty of having to sample and identify movement. Scientists at the University of Southampton, UK (
Another model considers the shape and length of legs as well as the velocity of joint movements. The objective is to combine both models into one, which would make gait recognition a fully applicable biometric technology.
Given that gait recognition is applied to "moving preambulatory subjects" it is a particularly interesting technology for surveillance. People can no longer hide their identity by covering themselves or moving. Female shop lifters who pretend pregnancy will be detected because they walk differently than those who are really pregnant. Potential wrongdoers might resort walking techniques as developed in Monty Pythons legendary "Ministry of Silly Walks" (

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 APC is a global federation of 24 non-profit Internet providers serving over 50,000 NGOs in 133 countries. Since 1990, APC has been supporting people and organizations worldwide, working together online for social, environmental and economic justice. The APC's network of members and partners spans the globe, with significant presence in Central and Eastern Europe, Africa, Asia and Latin America.
History
Between 1982 and 1987 several independent, national, non-profit computer networks emerged as viable information and communication resources for activists and NGOs. The networks were founded to make new communication techniques available to movements working for social change.
In 1987, people at GreenNet in England began collaborating with their counterparts at the Institute for Global Communications (IGC) in the United States. These two networks started sharing electronic conference material and demonstrated that transnational electronic communications could serve international as well as domestic communities working for peace, human rights and the environment.
This innovation proved so successful that by late 1989, networks in Sweden, Canada, Brazil, Nicaragua and Australia were exchanging information with each other and with IGC and GreenNet. In the spring of 1990, these seven organizations founded the Association for Progressive communications to co-ordinate the operation and development of this emerging global network of networks.
Strategies and Policies
The APC defends and promotes non-commercial, productive online space for NGOs and collaborates with like-minded organizations to ensure that the information and communication needs of civil society are considered in telecommunications, donor and investment policy. The APC is committed to freedom of expression and exchange of information on the Internet.
The APC helps to build capacity between existing and emerging communication service providers.
The APC Women's Networking Support Program promotes gender-aware Internet design, implementation and use.
Through its African members, the APC is trying to strengthen indigenous information sharing and independent networking capacity on the continent.
Members of APC develop Internet products, resources and tools to meet the advocacy, collaboration and information publishing and management needs of civil society. Recent APC initiatives have included the APC Toolkit Project: Online Publishing and Collaboration for Activists and the Mission-Driven Business Planning Toolkit.
The APC also runs special projects like the Beijing+5, which shall enable non-governmental organizations to actively participate in the review of the Beijing Platform for Action.

Although fingerprinting smacks of police techniques used long before the dawn of the information age, its digital successor finger scanning is the most widely used biometric technology. It relies on the fact that a fingerprint's uniqueness can be defined by analysing the so-called "minutiae" in somebody's fingerprint. Minutae include sweat pores, distance between ridges, bifurcations, etc. It is estimated that the likelihood of two individuals having the same fingerprint is less than one in a billion.
As an access control device, fingerprint scanning is particularly popular with military institutions, including the Pentagon, and military research facilities. Banks are also among the principal users of this technology, and there are efforts of major credit card companies such as Visa and MasterCard to incorporate this finger print recognition into the bank card environment.
Problems of inaccuracy resulting from oily, soiled or cracked skins, a major impediment in fingerprint technology, have recently been tackled by the development a contactless capturing device (
As in other biometric technologies, fingerprint recognition is an area where the "criminal justice" market meets the "security market", yet another indication of civilian spheres becomes indistinguishable from the military. The utopia of a prisonless society seems to come within the reach of a technology capable of undermining freedom by an upward spiral driven by identification needs and identification technologies.

Iris recognition relies upon the fact that every individuals retina has a unique structure. The iris landscape is composed of a corona, crypts, filaments, freckles, pits radial furrows and striatations. Iris scanning is considered a particularly accurate identification technology because the characteristics of the iris do not change during a persons lifetime, and because there are several hundred variables in an iris which can be measured. In addition, iris scanning is fast: it does not take longer than one or two seconds.
These are characteristics which have made iris scanning an attractive technology for high-security applications such as prison surveillance. Iris technology is also used for online identification where it can substitute identification by password. As in other biometric technologies, the use of iris scanning for the protection of privacy is a two-edged sword. The prevention of identity theft applies horizontally but not vertically, i.e. in so far as the data retrieval that accompanies identification and the data body which is created in the process has nothing to do with identity theft.

Advertising as referred to in most economic books is part of the marketing mix. Therefore advertising usually is closely associated with the aim of selling products and services. Still, developments like "branding" show a tendency towards the marketing of not only products and services, but of ideas and values. While advertising activities are also pursued by political parties, politicians and governmental as well as non-governmental organizations, most of the money flowing into the advertising industry comes from corporations. Although these clients come from such diverse fields, their intentions hardly differ. Attempting to influence the public, their main goal is to sell: Products, services, ideas, values and (political) ideology.

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 this communication system was destined to practical military use, the transmitted messages were encoded. The messages were kept such secretly, even those who transmit them from tower to tower did not capture their meaning, they just 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

This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network.
