Mormon Church v. Sandra and Jerald Tanner
In a ruling of December 1999, a federal judge in Utah temporarily barred two critics of the Mormon Church from posting on their website the Internet addresses of other sites featuring pirated copies of a Mormon text. The Judge said that it was likely that Sandra and Jerald Tanner had engaged in contributory copyright infringement when they posted the addresses of three Web sites that they knew, or should have known, contained the copies.

Today the talk about the so-called "information society" is ubiquitous. By many it is considered as the successor of the industrial society and said to represent a new form of societal and economical organization. This claim is based on the argument, that the information society uses a new kind of resource, which fundamentally differentiates from that of its industrial counterpart. Whereas industrial societies focus on physical objects, the information society's raw material is said to be knowledge and information. Yet the conception of the capitalist system, which underlies industrial societies, also continues to exist in an information-based environment. Although there have been changes in the forms of manufacture, the relations of production remain organized on the same basis. The principle of property.
In the context of a capitalist system based on industrial production the term property predominantly relates to material goods. Still even as in an information society the raw materials, resources and products change, the concept of property persists. It merely is extended and does no longer solely consider physical objects as property, but also attempts to put information into a set of property relations. This new kind of knowledge-based property is widely referred to as "

The result of this informatisation is the creation of a virtual body which is the exterior of a man or woman's social existence. It plays the same role that the physical body, except located in virtual space (it has no real location). The virtual body holds a certain emancipatory potential. It allows us to go to places and to do things which in the physical world would be impossible. It does not have the weight of the physical body, and is less conditioned by physical laws. It therefore allows one to create an identity of one's own, with much less restrictions than would apply in the physical world.
But this new freedom has a price. In the shadow of virtualisation, the data body has emerged. The data body is a virtual body which is composed of the files connected to an individual. As the
The virtual character of the data body means that social regulation that applies to the real body is absent. While there are limits to the manipulation and exploitation of the real body (even if these limits are not respected everywhere), there is little regulation concerning the manipulation and exploitation of the data body, although the manipulation of the data body is much easier to perform than that of the real body. The seizure of the data body from outside the concerned individual is often undetected as it has become part of the basic structure of an informatised society. But data bodies serve as raw material for the "New Economy". Both business and governments claim access to data bodies. Power can be exercised, and democratic decision-taking procedures bypassed by seizing data bodies. This totalitarian potential of the data body makes the data body a deeply problematic phenomenon that calls for an understanding of data as social construction rather than as something representative of an objective reality. How data bodies are generated, what happens to them and who has control over them is therefore a highly relevant political question.

These standards are called communication protocols, or the Internet Protocol Suite, and are implemented in Internet software. Sometimes the Internet Protocol Suite is erroneously identified with

Each packet is "pushed" from router to router via

Routing around depends on the location of the interruption and on the availability of intersecting points between networks. If, for example, an E-mail message is sent from Brussels to Athens and in Germany a channel is down, it will not affect access very much, the message will be routed around this damage, as long as a major Internet exchange is not affected. However, if access depends on a single backbone connection to the Internet and this connection is cut off, there is no way to route around.
In most parts of the world the Internet is therefore vulnerable to disruption. "The idea of the Internet as a highly distributed, redundant global communications system is a myth. Virtually all communications between countries take place through a very small number of bottlenecks, and the available bandwidth isn't that great," says Douglas Barnes. These bottlenecks are the network connections to neighboring countries. Many countries rely on a one single connection to the Net, and in some places, such as the Suez Canal, there is a concentration of fiber-optic cables of critical importance.

Personal data are collected, appropriated, processed and used for commercial purposes on a global scale. In order for such a global system to operate smoothly, there a server nodes at which the data streams converge. Among the foremost of these are the data bases of credit card companies, whose operation has long depended on global networking.
On top of credit card companies such as Visa, American Express, Master Card, and others. It would be erroneous to believe that the primary purpose of business of these companies is the provision of credit, and the facilitation of credit information for sale transactions. In fact, Information means much more than just credit information. In an advertisement of 1982, American Express described itself in these terms: ""Our product is information ...Information that charges airline tickets, hotel rooms, dining out, the newest fashions ...information that grows money funds buys and sells equities ...information that pays life insurance annuities ...information that schedules entertainment on cable television and electronically guards houses ...information that changes kroners into guilders and figures tax rates in Bermuda ..."
Information has become something like the gospel of the New Economy, a doctrine of salvation - the life blood of society, as Bill Gates expresses it. But behind information there are always data that need to be generated and collected. Because of the critical importance of data to the economy, their possession amounts to power and their loss can cause tremendous damage. The data industry therefore locates its data warehouses behind fortifications that bar physical or electronic access. Such structures are somewhat like a digital reconstruction of the medieval fortress

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.

1) Industrial Property
a)
b)
c)
d) Unfair competition (trade secrets)
e) Geographical indications (indications of source and appellations of origin)
2) Copyright
The protection of intellectual property is guaranteed through a variety of laws, which grant the creators of intellectual goods, and services certain time-limited rights to control the use made of their products. Those rights apply to the intellectual creation as such, and not to the physical object in which the work may be embodied.

The glamour of the data body economy clouds economic practices which are much less than glamorous. Through the seizure of the data body, practices that in the real political arena were common in the feudal age and in the early industrial age are being reconstructed. The data body economy digitally reconstructs exploitative practices such as slavery and wage labour. However, culturally the data body is still a very new phenomenon: mostly, people think if it does not hurt, it cannot be my body. Exploitation of data bodies is painless and fast. Nevertheless, this can be expected to change once the awareness of the political nature of the data body becomes more widespread. As more and more people routinely move in digitised environments, it is to be expected that more critical questions will be asked and claims to autonomy, at present restricted to some artistic and civil society groups trying to get heard amidst the deafening noise of the commercial ICT propaganda, will be articulated on a more general level.
The more problematic aspect of this development may be something else: the practices of the data body economy, themselves a reconstruction of old techniques of seizure, have begun to re-colonise real political space. Simon Davis, Director of the London-based privacy campaigners

The Net consists of thousands of thousands of governmental and private networks linked together. No legal authority determines how and where networks can be connected together, this is something the managers of networks have to agree about. So there is no way of ever gaining ultimate control of the Internet. Although each of these networks is operated and controlled by an organization, no single organization operates and controls the Net. Instead of a central authority governing the Net, several bodies assure the operability of the Net by developing and setting technical specifications for the Net and by the control of the technical key functions of the Net as the coordination of the domain name system and the allocation of IP numbers.
Originally, the Net was a research project funded and maintained by the US Government and developed in collaboration by scientists and engineers. As the standards developed for ensuring operability ensued from technical functionality, technical coordination gradually grew out of necessity and was restricted to a minimum and performed by volunteers.
Later, in the 1980s, those occupied with the development of technical specifications organized themselves under the umbrella of the Internet Society in virtual organizations as the Internet Engineering Task Force, which were neither officially established nor being based on other structures than mailing lists and commitment, but nonetheless still serve as task forces for the development of standards ensuring the interoperability on the Net.
Since the late 80s and the early 90s, with the enormous growth of the Net - which was promoted by the invention of

Generally copyright vests in the author of the work. Certain national laws provide for exceptions and, for example, regard the employer as the original owner of a copyright if the author was, when the work was created, an employee and employed for the purpose of creating that work. In the case of some types of creations, particularly audiovisual works, several national laws provide for different solutions to the question that should be the first holder of copyright in such works.
Many countries allow copyright to be assigned, which means that the owner of the copyright transfers it to another person or entity, which then becomes its holder. When the national law does not permit assignment it usually provides the possibility to license the work to someone else. Then the owner of the copyright remains the holder, but authorizes another person or entity to exercise all or some of his rights subject to possible limitations. Yet in any case the "

Framing
Frames are often used to help define, and navigate within, a content provider's website. Still, when they are used to present (copyrighted) third party material from other sites issues of passing off and misleading or deceptive conduct, as well as copyright infringement, immediately arise.
Hyperlinking
It is generally held that the mere creation of a hyperlink does not, of itself, infringe copyright as usually the words indicating a link or the displayed URL are unlikely to be considered a "work". Nevertheless if a link is clicked on the users browser will download a full copy of the material at the linked address creating a copy in the RAM of his computer courtesy of the address supplied by the party that published the link. Although it is widely agreed that the permission to download material over the link must be part of an implied license granted by the person who has made the material available on the web in the first place, the scope of this implied license is still the subject of debate. Another option that has been discussed is to consider linking
Furthermore hyperlinks, and other "information location tools", like online directories or search engines could cause their operators trouble if they refer or link users to a site that contains infringing material. In this case it is yet unclear whether providers can be held liable for infringement.

Reproduction and Distribution
Unlike copies of works made using analog copiers (photocopy machines, video recorders etc.) digital information can be reproduced extremely fast, at low cost and without any loss in quality. Since each copy is a perfect copy, no quality-related limits inhibit pirates from making as many copies as they please, and recipients of these copies have no incentive to return to authorized sources to get another qualitatively equal product. Additionally the costs of making one extra copy of intellectual property online are insignificant, as are the distribution costs if the copy is moved to the end user over the Internet.
Control and Manipulation
In cross-border, global data networks it is almost impossible to control the exploitation of protected works. Particularly the use of anonymous remailers and other existing technologies complicates the persecution of pirates.

In the phrase "the rise of the citizen as a consumer", to be found on the
When the citizen becomes a consumer, the state must become a business. In the data body business, the key word behind this new identity of government is "outsourcing". Functions, that are not considered core functions of government activity are put into the hands of private contractors.
There have long been instances where privately owned data companies, e.g. credit card companies, are allowed access to public records, e.g. public registries or electoral rolls. For example, in a normal credit card transaction, credit card companies have had access to public records in order to verify identity of a customer. For example, in the UK citizen's personal data stored on the Electoral Roll have been used for commercial purposes for a long time. The new British Data Protection Act now allows people to "opt out" of this kind of commercialisation - a legislation that has prompted protests on the part of the data industry:
While this may serve as an example of an increased public awareness of privacy issues, the trend towards outsourcing seems to lead to a complete breakdown of the barriers between commercial and public use of personal data. This trend can be summarised by the term "outsourcing" of government functions.
Governments increasingly outsource work that is not considered core function of government, e.g. cooking meals in hospitals or mowing lawns in public parks. Such peripheral activities marked a first step of outsourcing. In a further step, governmental functions were divided between executive and judgemental functions, and executive functions increasingly entrusted to private agencies. For these agencies to be able to carry out the work assigned to them, the need data. Data that one was stored in public places, and whose handling was therefore subject to democratic accountability. Outsourcing has produced gains in efficiency, and a decrease of accountability. Outsourced data are less secure, what use they are put to is difficult to control.

Technically the linking of different systems is already possible. It would also create more efficiency, which means generate more income. The question, then, whether democracy concerns will prevent it from happening is one that is capable of creating
But what the EDS example shows is something that applies everywhere, and that is that the data industry is whether by intention or whether by default, a project with profound political implications. The current that drives the global economy deeper and deeper into becoming a global data body economy may be too strong to be stopped by conventional means.
However, the convergence of political and economic data bodies also has technological roots. The problem is that politically motivated surveillance and economically motivated data collection are located in the same area of information and communication technologies. For example, monitoring internet use requires more or less the same technical equipment whether done for political or economic purposes. Data mining and data warehousing techniques are almost the same. Creating transparency of citizens and customers is therefore a common objective of intelligence services and the data body industry. Given that data are exchanged in electronic networks, a compatibility among the various systems is essential. This is another factor that encourages "leaks" between state-run intelligence networks and the private data body business. And finally, given the secretive nature of state intelligence and commercial data capturing , there is little transparency. Both structures occupy an opaque zone.

The water-clocks are an early long-distance-communication-system. Every communicating party had exactly the same jar, with a same-size-hole that was closed and the same amount of water in it. In the jar was a stick with different messages written on. When one party wanted to tell something to the other it made a fire-sign. When the other answered, both of them opened the hole at the same time. And with the help of another fire-sign closed it again at the same time, too. In the end the water covered the stick until the point of the wanted message.
ARPAnet was the small network of individual computers connected by leased lines that marked the beginning of today's global data networks. Being an experimental network mainly serving the purpose to test the feasibility of
In 1969 ARPANET went online and links the first two computers, one of them located at the University of California, Los Angeles, the other at the Stanford Research Institute.
But ARPAnet has not become widely accepted before it was demonstrated in action to a public of computer experts at the First International Conference on Computers and Communication in Washington, D. C. in 1972.
Before it was decommissioned in 1990,
In the USA commercial users already outnumbered military and academic users in 1994.
Despite the rapid growth of the Net, most computers linked to it are still located in the United States.

He laid the foundation for the modern theory of probabilities, formulated what came to be known as Pascal's law of pressure, and propagated a religious doctrine that taught the experience of God through the heart rather than through reason. The establishment of his principle of intuitionism had an impact on such later philosophers as Jean-Jacques Rousseau and Henri Bergson and also on the Existentialists.
Virtual Private Networks provide secured connections to a corporate site over a public network as the Internet. Data transmitted through secure connections are encrypted and therefore have to be encrypted before they can be read.
These networks are called virtual because connections are provided only when you connect to a corporate site; they do not rely on dedicated lines and support mobile use.
