Basics: Protected Persons 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 " | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

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."

Biometrics applications: privacy issues All biometric technologies capture biometric data from individuals. Once these date have been captured by a system, they can, in principle, be forwarded to other locations and put to many different uses which are capable of compromising on an individuals privacy. Technically it is easy to match biometric data with other personal data stored in government or corporate files, and to come a step closer to the counter-utopia of the transparent citizen and customer whose data body is under outside control. While biometric technologies are often portrayed as protectors of personal data and safeguards against identity theft, they can thus contribute to an advance in "Big Brother" technology. The combination of personalised data files with biometric data would amount to an enormous control potential. While nobody in government and industry would admit to such intentions, leading data systems companies such as EDS (Electronic Data Systems; Biometric technologies have the function of identification. Historically, identification has been a prerequisite for the exercise of power and serves as a protection only to those who are in no conflict with this power. If the digitalisation of the body by biometric technologies becomes as widespread as its proponents hope, a new electronic feudal system could be emerging, in which people are reduced to subjects dispossessed of their to their bodies, even if these, unlike in the previous one, are data bodies. Unlike the gatekeepers of medieval towns, wear no uniforms by they might be identified; biometric technologies are pure masks. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

In Search of Reliable Internet Measurement Data Newspapers and magazines frequently report growth rates of Internet usage, number of users, hosts, and domains that seem to be beyond all expectations. Growth rates are expected to accelerate exponentially. However, Internet measurement data are anything thant reliable and often quite fantastic constructs, that are nevertheless jumped upon by many media and decision makers because the technical difficulties in measuring Internet growth or usage are make reliable measurement techniques impossible. Equally, predictions that the Internet is about to collapse lack any foundation whatsoever. The researchers at the Size and Growth In fact, "today's Internet industry lacks any ability to evaluate trends, identity performance problems beyond the boundary of a single ISP (Internet service provider, M. S.), or prepare systematically for the growing expectations of its users. Historic or current data about traffic on the Internet infrastructure, maps depicting ... there is plenty of measurement occurring, albeit of questionable quality", says K. C. Claffy in his paper Internet measurement and data analysis: topology, workload, performance and routing statistics (http://www.caida.org/Papers/Nae/, Dec 6, 1999). Claffy is not an average researcher; he founded the well-known So his statement is a slap in the face of all market researchers stating otherwise. In a certain sense this is ridiculous, because since the inception of the So what are the reasons for this inability to evaluate trends, identity performance problems beyond the boundary of a single ISP? First, in early 1995, almost simultaneously with the worldwide introduction of the "There are many estimates of the size and growth rate of the Internet that are either implausible, or inconsistent, or even clearly wrong", K. G. Coffman and Andrew, both members of different departments of What is measured and what methods are used? Many studies are devoted to the number of users; others look at the number of computers connected to the Internet or count You get the clue of their focus when you bear in mind that the Internet is just one of many networks of networks; it is only a part of the universe of computer networks. Additionally, the Internet has public (unrestricted) and private (restricted) areas. Most studies consider only the public Internet, Coffman and Odlyzko consider the long-distance private line networks too: the corporate networks, the Hosts The Despite the small sample, this method has at least one flaw: Internet Weather Like daily weather, traffic on the Internet, the conditions for data flows, are monitored too, hence called Internet weather. One of the most famous Internet Hits, Page Views, Visits, and Users Let us take a look at how these hot lists of most visited Web sites may be compiled. I say, may be, because the methods used for data retrieval are mostly not fully disclosed. For some years it was seemingly common sense to report requested files from a Web site, so called "hits". A method not very useful, because a document can consist of several files: graphics, text, etc. Just compile a document from some text and some twenty flashy graphical files, put it on the Web and you get twenty-one hits per visit; the more graphics you add, the more hits and traffic (not automatically to your Web site) you generate. In the meantime page views, also called page impressions are preferred, which are said to avoid these flaws. But even page views are not reliable. Users might share computers and corresponding Especially the editors of some electronic journals (e-journals) rely on page views as a kind of ratings or circulation measure, Rick Marin reports in the More advanced, but just slightly better at best, is counting visits, the access of several pages of a Web site during one session. The problems already mentioned apply here too. To avoid them, newspapers, e.g., establish registration services, which require password authentication and therefore prove to be a kind of access obstacle.

Intellectual Property and the "Information Society" Metaphor 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 " | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

History: European Tradition Only in Roman times the first rights referring to artistic works appeared. Regulations resembling a lasting exclusive right to copy did not occur until the 17th century. Before copyright was a private arrangement between guilds able to reproduce copies in commercial quantities. In France and Western European countries "droits d'auteur" or author's rights is the core of what in the Anglo-American tradition is called copyright. Such rights are rooted in the republican revolution of the late 18th century, and the Rights of Man movement. Today in the European system the creator is front and center; later exploiters are only secondary players. France During the 18th century France gradually lost the ability to restrict In 1777 the King threatened the monopoly by reducing the duration of publisher's privileges to the lifetime of the authors. Accordingly a writer's work would go into the public domain after his death and could be printed by anyone. The booksellers fought back by argumenting that, no authority could take their property from them and give it to someone else. Seven months later, in August 1789, the revolutionary government ended the privilege system and from that time on anyone could print anything. Early in 1790 Marie-Jean-Antoine-Nicolas de Caritat, Marquis de Condorcet proposed giving authors power over their own work lasting until ten years after their deaths. The proposal - the basis for France's first modern copyright law - passed in 1793. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Acessing the Internet The Net connections can be based on wire-line and wireless access technolgies.
Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables Satellite communication Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks. Privatization of satellite communication Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as Scheduled privatization of intergovernmental satellite consortia:
When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers. As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost. Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

Challenges for Copyright by ICT: Copyright Owners The main concern of copyright owners as the (in terms of 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.

Yet the emergence and increased use of global data networks and the WWW has added a new dimension to the piracy of This new development, often referred to as Internet piracy, broadly relates to the use of global data networks to 1) transmit and download digitized copies of pirated works, 2) advertise and market pirated intellectual property that is delivered on physical media through the mails or other traditional means, and 3) offer and transmit codes or other technologies which can be used to circumvent Lately the Table: IIPA 1998 - 1999 Estimated Trade Loss due to Copyright Piracy (in millions of US$)

How the Internet works On the Internet, when you want to retrieve a document from another computer, you request a service from this computer. Your computer is the client, the computer on which the information you want to access is stored, is called the A common set of standards allows the exchange of data and commands independent from locations, time, and operating systems through the Internet. 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 Any information to be transferred is broken down into pieces, so-called packets, and the Internet Protocol figures out how the data is supposed to get from A to B by passing through routers. Each packet is "pushed" from router to router via The technique of breaking down all messages and requests into packets has the advantage that a large data bundle (e.g. videos) sent by a single user cannot block a whole network, because the One of the Internet's (and of the Matrix's) beginnings was the 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. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Copyright Management and Control Systems: Pre-Infringement Pre-infringement Contracts Contracts are a pre-infringement control method, which very often is underestimated. Properly formed contracts enable copyright holders to restrict the use of their works in excess of the rights granted under copyright laws. Copy Protection This approach was standard in the 1980s, but rejected by consumers and relatively easy to break. Still copy protection, whereby the vendor limits the number of times a file can be copied, is used in certain situations. Limited Functionality This method allows copyright owners to provide a copy of the work, which is functionally limited. Software creators, for example, can distribute software that cannot print or save. A fully functional version has to be bought from the vendor. Date Bombs Here the intellectual property holder distributes a fully functional copy but locks off access at a pre-specified date or after a certain number of uses. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

water-clocks 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. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

retouch The retouch is the simplest way to change a picture. Small corrections can be made through this way. A well-known example is the correction of a picture from a Bill Clinton-visit in Germany. In the background of the photograph stood some people, holding a sign with critical comments. In some newspapers the picture was printed like this, in others a retouch had erased the sign. Another example happened in Austria in 1999: The right wing party FPÖ had a poster for the Parliamentarian elections which said: 1999 reasons to vote for Haider. Others answered by producing a retouch saying: 1938 reasons to not vote for Haider (pointing to the year 1939, when the vast majority of the Austrians voted for the "Anschluss" to Germany). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
