Following the invention of the first
Also, ensuing the introduction of the minicomputer in the mid 1970s by the early 1980s a market for personal computers (PC) was established. As computers had become easier to use and cheaper they were no longer mainly utilized in offices and manufacturing, but also by the average consumer. Therefore the number of personal computers in use more than doubled from 2 million in 1981 to 5.5 million in 1982. Ten years later, 65 million PCs were being used.
Further developments included the creation of mobile computers (laptops and palmtops) and especially networking technology. While mainframes shared time with many terminals for many applications, networking allowed individual computers to form electronic co-operations.

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" (
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.

The Romans can be called the great inventors of myths with the purpose of propaganda. Think of
Or Augustus: he reunited the Roman Empire; part of his power was due to huge efforts in propaganda, visible e.g. in the mass of coins showing his face, being sent all over the empire. He understood very well, that different cultures used different symbols - and he used them for his propaganda.
Politically the Roman army was an important factor. Propaganda in that case was used for the soldiers on the one hand, but on the other hand also for demonstrating the power of the army to the people, so they could trust in its strength. Even then security was an essential factor of politics. As long as the army functioned, the Roman Empire did as well (
