1605/1623 Sir Francis Bacon (= Francis Tudor = William Shakespeare?) writes several works containing ideas about cryptography. One of his most important advises is to use ciphers in such a way that no-one gets suspicious that the text could be enciphered. For this the steganogram was the best method, very often used in poems. The attempt to decipher Shakespeare's sonnets (in the 20th century) lead to the idea that his works had been written by Francis Bacon originally.

The first of the great medieval universities was established in Bologna. At the beginning universities predominantly offered a kind of do-it-yourself publishing service.
Books still had to be copied by hand and were so rare that a copy of a widely desired book qualified for being invited to a university. Holding a lecture equaled to reading a book aloud, like a priest read from the Bible during services. Attending a lecture equaled to copy a lecture word by word, so that you had your own copy of a book, thus enabling you to hold a lecture, too.

In biometric technology, the subject is reduced to its physical and therefore inseparable properties. The subject is a subject in so far as it is objectified; that is, in so far as is identified with its own res extensa, Descartes' "extended thing". The subject exists in so far as it can be objectified, if it resists the objectification that comes with measurement, it is rejected or punished. Biometrics therefore provides the ultimate tool for control; in it, the dream of hermetic identity control seems to become a reality, a modern technological reconstruction of traditional identification techniques such as the handshake or the look into somebody's eyes.
The use of identification by states and other institutions of authority is evidently not simply a modern phenomenon. The ancient Babylonians and Chinese already made use of finger printing on clay to identify authors of documents, while the Romans already systematically compared handwritings.
Body measurement has long been used by the military. One of the first measures after entering the military is the identification and appropriation of the body measurements of a soldier. These measurements are filed and combined with other data and make up what today we would call the soldier's data body. With his data body being in possession of the authority, a soldier is no longer able freely socialise and is instead dependent on the disciplinary structure of the military institution. The soldier's social being in the world is defined by the military institution.
However, the military and civilian spheres of modern societies are no longer distinct entities. The very ambivalence of advanced technology (dual use technologies) has meant that "good" and "bad" uses of technology can no longer be clearly distinguished. The measurement of physical properties and the creation of data bodies in therefore no longer a military prerogative, it has become diffused into all areas of modern societies.
If the emancipatory potential of weak identities is to be of use, it is therefore necessary to know how biometric technologies work and what uses they are put to.

Global data bodies
1. Introduction
Informatisation has meant that things that once were "real", i.e. whose existence could be experienced sensually, are becoming virtual. Instead of the real existence of a thing, the virtual refers to its possibility of existence. As this process advances, an increasing identification of the possible with the real occurs. Reality migrates into a dim and dematerialised grey area. In the end, the possible counts for the real, virtualisation creates an "as-if" experience.
The experience of the body is also affected by this process. For example, in bio-technology, the human body and its functions are digitised, which prepares and understanding of the body exlusively in terms of its potential manipulation, the body becomes whatever it could be. But digitisation has not only affected the understanding and the social significance of the body, it has also altered the meaning of presence, traditionally identified with the body. The advance of information and communication technologies (ICTs) has meant that for an increasing number of activities we no longer need be physically present, our "virtual" presence, achieved by logging onto a electronic information network, is sufficient.
This development, trumpeted as the pinnacle of convenience by the ICT industries and governments interested in attracting investment, has deeply problematic aspects as well. For example, when it is no longer "necessary" to be physically present, it may soon no longer be possible or allowed. Online-banking, offered to customers as a convenience, is also serves as a justification for charging higher fees from those unwilling or unable to add banking to their household chores. Online public administration may be expected to lead to similar effects. The reason for this is that the digitalisation of the economy relies on the production of surplus data. Data has become the most important raw material of modern economies.
In modern economies, informatisation and virtualisation mean that people are structurally forced to carry out their business and life their lives in such a way as to generate data.
Data are the most important resource for the New Economy. By contrast, activities which do not leave behind a trace of data, as for example growing your own carrots or paying cash rather than by plastic card, are discouraged and structurally suppressed.

Biometric technologies are not surveillance technologies in themselves, but as identification technologies they provide an input into surveillance which can make such as face recognition are combined with camera systems and criminal data banks in order to supervise public places and single out individuals.
Another example is the use of biometrics technologies is in the supervision of probationers, who in this way can carry their special hybrid status between imprisonment and freedom with them, so that they can be tracked down easily.
Unlike biometric applications in access control, where one is aware of the biometric data extraction process, what makes biometrics used in surveillance a particularly critical issue is the fact that biometric samples are extracted routinely, unnoticed by the individuals concerned.

Yet again new technologies have altered the way of how (copyrighted) works are produced, copied, made obtainable and distributed. The emergence of global electronic networks and the increased availability of digitalized intellectual property confront existing copyright with a variety of questions and challenges. Although the combination of several types of works within one larger work or on one data carrier, and the digital format (although this may be a recent development it has been the object of detailed legal scrutiny), as well as networking (telephone and cable networks have been in use for a long time, although they do not permit interactivity) are nothing really new, the circumstance that recent technologies allow the presentation and storage of text, sound and visual information in digital form indeed is a novel fact. Like that the entire information can be generated, altered and used by and on one and the same device, irrespective of whether it is provided online or offline.

Following the communist revolutions of the 20th century all "means of production" became the property of the state as representative of "the masses". Private property ceased to exist. While moral rights of the creator were recognized and economic rights acknowledged with a one-time cash award, all subsequent rights reverted to the state.
With the transformation of many communist countries to a market system most of them have now introduced laws establishing markets in intellectual property rights. Still the high rate of piracy reflects a certain lack of legal tradition.

Identity has to do with "place". In less mobile societies, the place where a person finds him/herself tells us something about his/her identity. In pre-industrial times, gatekeepers had the function to control access of people to particular places, i.e. the gatekeepers function was to identify people and then decide whether somebody's identity would allow that person to physically occupy another place - a town, a building, a vehicle, etc.
In modern societies, the unambiguous nature of place has been weakened. There is a great amount of physical mobility, and ever since the emergence and spread of electronic communication technologies there has been a "virtualisation" of places in what today we call "virtual space" (unlike place, space has been a virtual reality from the beginning, a mathematical formula) The question as to who one is no longer coupled to the physical abode. Highly mobile and virtualised social contexts require a new generation of gatekeepers which biometric technology aims to provide.

With the dissemination of their content commercial media are among other things also able to transport values and ideologies. Usually their programming reflects society's dominant social, political, ethical, cultural and economical values. A critical view of the prevalent ideologies often is sacrificed so as not to offend the existing political elites and corporate powers, but rather satisfy shareholders and advertisers.
With most of the worlds content produced by a few commercial media conglomerates, with the overwhelming majority of companies (in terms of revenue generation) concentrated in Europe, the U.S., Japan and Australia there is also a strong flow of content from the 'North-West' to the 'South-East'. Popular culture developed in the world's dominant commercial centers and Western values and ideologies are so disseminated into the most distant corners of the earth with far less coming back.

This is the largest area of application of biometric technologies, and the most direct lineage to the feudal gate keeping system. Initially mainly used in military and other "high security" territories, physical access control by biometric technology is spreading into a much wider field of application. Biometric access control technologies are already being used in schools, supermarkets, hospitals and commercial centres, where the are used to manage the flow of personnel.
Biometric technologies are also used to control access to political territory, as in immigration (airports, Mexico-USA border crossing). In this case, they can be coupled with camera surveillance systems and artificial intelligence in order to identify potential suspects at unmanned border crossings. Examples of such uses in remote video inspection systems can be found at

"All enrolees are compared against national lookout databases on a daily basis to ensure that individuals remain low risk". As a side benefit, the economy of time generated by the inspection system has meant that "drug seizures ... have increased since Inspectors are able to spend more time evaluating higher risk vehicles".
However, biometric access control can not only prevent people from gaining access on to a territory or building, they can also prevent them from getting out of buildings, as in the

Even with the best techniques it is impossible to invent a cryptographic system that is absolutely safe/unbreakable. To decipher a text means to go through many, sometimes nearly - but never really - endless attempts. For the computers of today it might take hundreds of years or even more to go through all possibilities of codes, but still, finally the code stays breakable. The much faster quantum computers will proof that one day.
Therefore the decision to elect a certain method of enciphering finally is a matter of trust.
For the average user of computers it is rather difficult to understand or even realize the dangers and/or the technological background of electronic transmission of data. For the majority thinking about one's own necessities for encryption first of all means to trust others, the specialists, to rely on the information they provide.
The websites explaining the problems behind (and also the articles and books concerning the topic) are written by experts of course as well, very often in their typical scientific language, merely understandable for laymen. The introductions and other superficial elements of those articles can be understood, whereas the real background appears as untouchable spheres of knowledge.
The fact that dangers are hard to see through and the need for security measures appears as something most people know from media reports, leads directly to the problem of an underdeveloped democracy in the field of cryptography. Obviously the connection between cryptography and democracy is rather invisible for many people. Those mentioned media reports often specialize in talking about the work computer hackers do (sometimes being presented as criminals, sometimes as heroes) and the danger to lose control over the money drawn away from one's bank account, if someone steals the credit card number or other important financial data. The term "security", surely connected to those issues, is a completely different one from the one that is connected to privacy.
It is especially the latter that touches the main elements of democracy.

Although fingerprinting smacks of police techniques used long before the dawn of the information age, its digital successor finger scanning is the most widely used biometric technology. It relies on the fact that a fingerprint's uniqueness can be defined by analysing the so-called "minutiae" in somebody's fingerprint. Minutae include sweat pores, distance between ridges, bifurcations, etc. It is estimated that the likelihood of two individuals having the same fingerprint is less than one in a billion.
As an access control device, fingerprint scanning is particularly popular with military institutions, including the Pentagon, and military research facilities. Banks are also among the principal users of this technology, and there are efforts of major credit card companies such as Visa and MasterCard to incorporate this finger print recognition into the bank card environment.
Problems of inaccuracy resulting from oily, soiled or cracked skins, a major impediment in fingerprint technology, have recently been tackled by the development a contactless capturing device (

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.

The bandwidth of a transmitted communications signal is a measure of the range of frequencies the signal occupies. The term is also used in reference to the frequency-response characteristics of a communications receiving system. All transmitted signals, whether analog or digital, have a certain bandwidth. The same is true of receiving systems.
Generally speaking, bandwidth is directly proportional to the amount of data transmitted or received per unit time. In a qualitative sense, bandwidth is proportional to the complexity of the data for a given level of system performance. For example, it takes more bandwidth to download a photograph in one second than it takes to download a page of text in one second. Large sound files, computer programs, and animated videos require still more bandwidth for acceptable system performance. Virtual reality (VR) and full-length three-dimensional audio/visual presentations require the most bandwidth of all.
In digital systems, bandwidth is data speed in bits per second (bps).

He was appointed underminister of labour in 1948 and the following year became minister of public health and labour, a post that he retained until May 10, 1950, when President Estimé was overthrown by a military junta under Paul E. Magloire, who was subsequently elected president. By 1954 he had become the central opposition figure and went underground. Duvalier was elected president in September 1957. Setting about to consolidate his power, he reduced the size of the army and organized the Tontons Macoutes ("Bogeymen"), a private force responsible for terrorizing and assassinating alleged foes of the regime. Late in 1963 Duvalier moved further toward an absolutist regime, promoting a cult of his person as the semi divine embodiment of the Haitian nation. In April 1964 he was declared president for life. Although diplomatically almost completely isolated, excommunicated by the Vatican until 1966 for harassing the clergy, and threatened by conspiracies against him, Duvalier was able to stay in power longer than any of his predecessors.
The first of the great medieval universities was established at Bologna. At the beginning, universities predominantly offered a kind of do-it-yourself publishing service.
Books still had to be copied by hand and were so rare that a copy of a widely desired book qualified for being invited to a university. Holding a lecture equaled to reading a book aloud, like a priest read from the Bible during services. Attending a lecture equaled to copy a lecture word by word, so you had your own copy of a book, thus enabling you to hold a lecture, too.
