Economic structure; transparent customers Following the dynamics of informatised economies, the consumption habits and lifestyles if customers are of great interest. New technologies make it possible to store and combine collected data of an enormous amount of people. User profiling helps companies understand what potential customers might want. Often enough, such data collecting takes place without the customer's knowledge and amounts to spying. "Much of the information collection that occurs on the Internet is invisible to the consumer, which raises serious questions of fairness and informed consent." (David Sobel, Electronic Privacy Information Center) |

Optical communication system by Aeneas Tacitus, 4th century B.C. Aeneas Tacitus, a Greek military scientist and cryptographer, invented an optical communication system that combines water and beacon telegraphy. Torches indicated the beginnings and the ends of message transmissions while water jars were used to transmit the messages. These jars had a plugged standard-size hole drilled on the bottom side and were filled with water. As those who sent and those who received the message unplugged the jars simultaneously, the water drained out. Because the transmitted messages corresponded to water levels, the sender indicated by torch signal that the appropriate water level has been reached. It is a disadvantage that the possible messages are restricted to a given code, but as this system was mainly used for military purposes, this was offset by the advantage that it was almost impossible for outsiders to understand these messages unless they possessed the codebook. With communication separated from transportation, the distant became near. Tacitus' telegraph system was very fast and not excelled until For further information see Joanne Chang & Anna Soellner, Decoding Device, |

Electronic Data Interchange (EDI) EDI is an international standard relating to the exchange of trade goods and services. It enables trading partners to conduct routine business transactions, such as purchase orders, invoices and shipping notices independent of the computer platform used by the trading partners. Standardization by EDI translation software assures the correct interpretation of data. EDI might become increasingly important to electronic commerce. |
