Gait recognition

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 (http://www.isis.ecs.soton.ac.uk/research/gait/) have developed a model which likens the movement of legs to those of a pendulum and uses hip inclination as a variable.

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" (http://www.stone-dead.asn.au/sketches/sillwalk.htm)

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.

Advertising

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.

Automation

Automation is concerned with the application of machines to tasks once performed by humans or, increasingly, to tasks that would otherwise be impossible. Although the term mechanization is often used to refer to the simple replacement of human labor by machines, automation generally implies the integration of machines into a self-governing system. Automation has revolutionized those areas in which it has been introduced, and there is scarcely an aspect of modern life that has been unaffected by it. Nearly all industrial installations of automation, and in particular robotics, involve a replacement of human labor by an automated system. Therefore, one of the direct effects of automation in factory operations is the dislocation of human labor from the workplace. The long-term effects of automation on employment and unemployment rates are debatable. Most studies in this area have been controversial and inconclusive. As of the early 1990s, there were fewer than 100,000 robots installed in American factories, compared with a total work force of more than 100 million persons, about 20 million of whom work in factories.

Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks

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.

Sony Corporation

Japanese SONY KK, major Japanese manufacturer of consumer electronics products. Headquarters are in Tokyo. The company was incorporated in 1946 and spearheaded Japan's drive to become the world's dominant consumer electronics manufacturer in the late 20th century. The company was one of the first to recognize the potential of the consumer videotape market. In 1972 it formed an affiliate to market its Betamax colour videocassette system. In 1987-88 Sony purchased the CBS Records Group from CBS Inc., thus acquiring the world's largest record company. It followed that purchase with the purchase in 1989 of Columbia Pictures Entertainment Inc.
