fingerprint identification

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 (http://www.ddsi-cpc.com) which translates the characteristics of a fingerprint into a digitised image.

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.

Eliminating online censorship: Freenet, Free Haven and Publius

Protecting speech on the global data networks attracts an increasing attention. The efforts and the corresponding abilities of governmental authorities, corporations and copyright enforcement agencies are countered by similar efforts and abilities of researchers and engineers to provide means for anonymous and uncensored communication, as Freenet, Free Haven and Publius. All three of them show a similar design. Content is split up and spread on several servers. When a file is requested, the pieces are reassembled. This design makes it difficult to censor content. All of these systems are not commercial products.

The most advanced system seems to be Publius. Because of being designed by researchers and engineers at the prestigious AT&T Labs, Publius is a strong statement against online censorship. No longer can it be said that taking a firm stand against the use of technologies limiting the freedom of individuals is a position of radical leftists only.

For more information on Publius, see John Schwartz, Online and Unidentifiable? in: The Washington Post, June 30, 2000, http://www.washingtonpost.com/wp-dyn/articles/A21689-2000Jun29.html .

Biometric technologies

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" (http://www.icsa.net/services/consortia/cbdc/bg/introduction.shtml); biometrics is the study and application of such measurable characteristics. In IT environments, biometrics are categorised as "security" technologies meant to limit access to information, places and other resources to a specific group of people.

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.

Changes

Still, disinformation and propaganda are nothing magic. They can change things, but supposedly only if those things/meanings/opinions are not fixed completely. Galileo Galilee was not capable of changing people's opinion about the world being flat until some persons got suspicious that this long-believed-in truth was a mistake. The propaganda of his experiments which made him famous was not enough. On the other hand later all the propaganda of his enemies could not turn back the wheel of enlightenment, as people thought it was more logic to believe in a round world than in a flat one.
It is never just a single idea that changes. Society is following the changes.

Thinking about disinformation brings us to the word truth, of course, and to the doubt that there is no definite truth. And truth can easily be manipulated to another truth. Just present some facts that seem to be logic and there you've got a new truth. And if the facts can supposedly be proved by empirical studies then the quality of the truth definitely rises.
That's what ideologies do all the time. And the media like to do the same thing - as a game with power or mere presentation of power?

But of course there also exist bits of disinformation which are more amusing than evil or dangerous:
- the theory of the celestro-centric world/"Hohlwelttheorie"
- the story of the German philosopher who invented an Italian philosopher, wrote books about him, even reprinted "his" texts, which had gone lost pretendedly 100 years ago - and finally lost his job and all his career when other scientists found out that everything had been made up.

UNIVAC

Built by Remington Rand in 1951 the UNIVAC I (Universal Automatic Computer) was one of the first commercially available computers to take advantage of the development of the central processing unit (CPU). Both the U.S. Census bureau and General Electric owned UNIVACs. Speed: 1,905 operations per second; input/output: magnetic tape, unityper, printer; memory size: 1,000 12-digit words in delay line; technology: serial vacuum tubes, delay lines, magnetic tape; floor space: 943 cubic feet; cost: F.O.B. factory U.S.$ 750,000 plus U.S.$ 185,000 for a high speed printer.

NSFNet

Developed under the auspices of the National Science Foundation (NSF), NSFnet served as the successor of the ARPAnet as the main network linking universities and research facilities until 1995, when it was replaced it with a commercial backbone network. Being research networks, ARPAnet and NSFnet served as testing grounds for future networks.

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.

An entertaining report of the laying of the FLAG submarine cable, up to now the longest fiber-optic cable on earth, including detailed background information on the cable industry and its history, Neal Stephenson has written for Wired: Mother Earth Mother Board. Click here for reading.

Susan Dumett has written a short history of undersea cables for Pretext magazine, Evolution of a Wired World. Click here for reading.

A timeline history of submarine cables and a detailed list of seemingly all submarine cables of the world, operational, planned and out of service, can be found on the Web site of the International Cable Protection Committee.
