1960s - 1970s: Expert Systems Gain Attendance The concept of expert systems dates back to the 1960s but first gained prominence in the 1970s. Conclusive for this development were the insights of the Stanford University professor Edward Feigenbaum, who in 1977 demonstrated that the problem-solving capacity of a computer program rather is a result of the knowledge it posses, than of the applied programming techniques and formalisms. Expert systems were designed to mimic the knowledge and reasoning capabilities of a human specialist in a given domain by using (top down) artificial intelligence techniques. Made possible by the large storage capacity of the computers at the time, expert systems had the potential to interpret statistics and formulate rules. An initial use of expert systems was to diagnose and treat human physical disorders, but as its applications in the market place were extensive over the course of the following years they were also employed in fields such as stock market forecast, taxation, chemistry, and geology.

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)

Edward L. Bernays Born 1891 in Vienna, Bernays was one of the founders of modern public relations. An enigmatic character, he was a master of mise en scène with far-reaching contacts in the world of business and politics. The nephew of Sigmund Freund and related with Heinrich Heine, he was also among the first to pursue PR for governments and to produce pseudo-events. Bernays considered the manipulation of public opinion as an important element of mass democracies and was of the opinion that only through PR a society's order can be kept.
