4000 - 1000 B.C. 4th millennium B.C. In Sumer Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets were used for administrative purposes. As an instrument for the administrative bodies of early empires, which began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to only very few. Being more or less separated tasks, writing and calculating converge in today's computers. Letters are invented so that we might be able to converse even with the absent, says Saint Augustine. The invention of writing made it possible to transmit and store information. No longer the ear predominates; face-to-face communication becomes more and more obsolete for administration and bureaucracy. Standardization and centralization become the constituents of high culture and vast empires as Sumer and China. 3200 B.C. In Sumer the seal is invented. About 3000 B.C.

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 ( 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" ( |
