Aeneas Tacitus' optical communication system

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 a message transmission 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 a torch signal that the appropriate water level had been reached. The methods disadvantage was that the possible messages were restricted to a given code, but as the system was mainly used for military purposes, this was offset by the advantage that it was almost impossible for outsiders to understand the 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 the end of the 18th century.

Codices replace scrolls

The use of codices instead of scrolls - basically the hardcover book as we know it today - is an essential event in European history. To quote accurately by page number, to browse through pages and to skip chapters - things that were impossible when reading scrolls - becomes possible.

In the computer age we are witnesses to a kind of revival of the scrolls as we scroll up and down a document. The introduction of hypertext possibly marks the beginning of a similar change as has taken place with the substitution of scrolls with codices.

Challenges for Copyright by ICT: Internet Service Providers

ISPs (Internet Service Providers) (and to a certain extent also telecom operators) are involved in the copyright debate primarily because of their role in the transmission and storage of digital information. Problems arise particularly concerning caching, information residing on systems or networks of ISPs at the directions of users and transitory communication.

Caching

Caching it is argued could cause damage because the copies in the cache are not necessarily the most current ones and the delivery of outdated information to users could deprive website operators of accurate "hit" information (information about the number of requests for a particular material on a website) from which advertising revenue is frequently calculated. Similarly harms such as defamation or infringement that existed on the original page may propagate for years until flushed from each cache where they have been replicated.

Although different concepts, similar issues to caching arise with mirroring (establishing an identical copy of a website on a different server), archiving (providing a historical repository for information, such as with newsgroups and mailing lists), and full-text indexing (the copying of a document for loading into a full-text or nearly full-text database which is searchable for keywords or concepts).

Under a literal reading of some copyright laws caching constitutes an infringement of copyright. Yet recent legislation like the DMCA or the proposed EU Directive on copyright and related rights in the information society (amended version) have provided exceptions for ISPs concerning particular acts of reproduction that are considered technical copies (caching). Nevertheless the exemption of liability for ISPs only applies if they meet a variety of specific conditions. In the course of the debate about caching also suggestions have been made to subject it to an implied license or fair use defense or make it (at least theoretically) actionable.

Information Residing on Systems or Networks at the Direction of Users

ISPs may be confronted with problems if infringing material on websites (of users) is hosted on their systems. Although some copyright laws like the DMCA provide for limitations on the liability of ISPs if certain conditions are met, it is yet unclear if ISPs should generally be accountable for the storage of infringing material (even if they do not have actual knowledge) or exceptions be established under specific circumstances.

Transitory Communication

In the course of transmitting digital information from one point on a network to another ISPs act as a data conduit. If a user requests information ISPs engage in the transmission, providing of a connection, or routing thereof. In the case of a person sending infringing material over a network, and the ISP merely providing facilities for the transmission it is widely held that they should not be liable for infringement. Yet some copyright laws like the DMCA provide for a limitation (which also covers the intermediate and transient copies that are made automatically in the operation of a network) of liability only if the ISPs activities meet certain conditions.

Linking and Framing: Cases

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.

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; http://www.eds.com) are also suppliers of biometric systems to the intelligence agencies of government and industry.

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.

Copyright Management and Control Systems: Post-Infringement

Post-infringement technologies allow the owners of copyrighted works to identify infringements and thus enhance enforcement of intellectual property rights and encompass systems such as:

Steganography

Applied to electronic files, steganography refers to the process of hiding information in files that can not be easily detected by users. Steganography can be used by intellectual property owners in a variety of ways. One is to insert into the file a "digital watermark" which can be used to prove that an infringing file was the creation of the copyright holder and not the pirate. Other possibilities are to encode a unique serial number into each authorized copy or file, enabling the owner to trace infringing copies to a particular source, or to store copyright management information.

Agents

Agents are programs that can implement specified commands automatically. Copyright owners can use agents to search the public spaces of the Internet to find infringing copies. Although the technology is not yet very well developed full-text search engines allow similar uses.

Copyright Litigation

While not every infringement will be the subject of litigation, the threat of litigation helps keep large pirate operations in check. It helps copyright owners obtain relief for specific acts of infringement and publicly warns others of the dangers of infringement.

Online data capturing

Hardly a firm today can afford not to engage in electronic commerce if it does not want to be swept out of business by competitors. "Information is everything" has become something like the Lord's prayer of the New Economy. But how do you get information about your customer online? Who are the people who visit a website, where do they come from, what are they looking for? How much money do they have, what might they want to buy? These are key questions for a company doing electronic business. Obviously not all of this information can be obtained by monitoring the online behaviour of web users, but there are always little gimmicks that, when combined with common tracking technologies, can help to get more detailed information about a potential customer. These are usually online registration forms, either required for entry to a site, or competitions, sometimes a combination of the two. Obviously, if you want to win that weekend trip to New York, you want to provide your contact details.

The most common way of obtaining information about a user online is a cookie. However, a cookie by itself is not sufficient to identify a user personally. It merely identifies the computer to the server by providing its IP number. Only combined with other data extraction techniques, such as online registration, can a user be identified personally ("Register now to get the full benefit of xy.com. It's free!")

But cookies record enough information to fine-tune advertising strategies according to a user's preferences and interests, e.g. by displaying certain commercial banners rather than others. For example, if a user is found to respond to a banner of a particular kind, he / she may find two of them at the next visit. Customizing the offers on a website to the particular user is part of one-to-one marketing, a type of direct marketing. But one-to-one marketing can go further than this. It can also offer different prices to different users. This was done by Amazon.com in September 2000, when fist-time visitors were offered cheaper prices than regular customers.

One-to-one marketing can create very different realities that undermine traditional concepts of demand and supply. The ideal is a "frictionless market", where the differential between demand and supply is progressively eliminated. If a market is considered a structure within which demand / supply differentials are negotiated, this amounts to the abolition of the established notion of the nature of a market. Demand and supply converge, desire and it fulfilment coincide. In the end, there is profit without labour. However, such a structure is a hermetic structure of unfreedom.

It can only function when payment is substituted by credit, and the exploitation of work power by the exploitation of data. In fact, in modern economies there is great pressure to increase spending on credit. Using credit cards and taking up loans generates a lot of data around a person's economic behaviour, while at the same restricting the scope of social activity and increasing dependence. On the global level, the consequences of credit spirals can be observed in many of the developing countries that have had to abandon most of their political autonomy. As the data body economy advances, this is also the fate of people in western societies when they are structurally driven into credit spending. It shows that data bodies are not politically neutral.

The interrelation between data, profit and unfreedom is frequently overlooked by citizens and customers. Any company in a modern economy will apply data collecting strategies for profit, with dependence and unfreedom as a "secondary effect". The hunger for data has made IT companies eager to profit from e-business rather resourceful. "Getting to know the customer" - this is a catchphrase that is heard frequently, and which suggests that there are no limits to what a company may want to about a customer. In large online shops, such as amazon.com, where customer's identity is accurately established by the practice of paying with credit cards, an all business happens online, making it easy for the company to accurately profile the customers.

But there are more advanced and effective ways of identification. The German company Sevenval has developed a new way of customer tracking which works with "virtual domains". Every visitor of a website is assigned an 33-digit identification number which the browser understands as part of the www address, which will then read something like http://XCF49BEB7E97C00A328BF562BAAC75FB2.sevenval.com. Therefore, this tracking method, which is advertised by Sevenval as a revolutionary method capable of tracking the exact and complete path of a user on a website, can not be simple switched off. In addition, the method makes it possible for the identity of a user can travel with him when he / she visits one of the other companies linked to the site in question. As in the case of cookies, this tracking method by itself is not sufficient to identify a user personally. Such an identification only occurs once a customer pays with a credit card, or decides to participate in a draw, or voluntarily completes a registration form.

Bu there are much less friendly ways of extracting data from a user and feeding the data body. Less friendly means: these methods monitor users in situations where the latter are likely not to want to be monitored. Monitoring therefore takes place in a concealed manner. One of these monitoring methods are so-called web bugs. These are tiny graphics, not more than 1 x 1 pixel in size, and therefore invisible on a screen, capable of monitoring an unsuspecting user's e-mails or movements on a website. Leading corporations such as Barnes and Noble, eToys, Cooking.com, and Microsoft have all used web bugs in advertising campaigns. Richard Smith has compiled a web bugs FAQ site that contains detailed information and examples of web bugs in use.

Bugs monitoring users have also been packaged in seemingly harmless toys made available on the Internet. For example, Comet Systems offers cursor images which have been shown to collect user data and send them back to the company's server. These little images replace the customary white arrow of a mouse with a little image of a baseball, a cat, an UFO, etc. large enough to carry a bug collecting user information. The technology is offered as a marketing tool to companies looking for a "fun, new way to interact with their audience".

The cursor image technology relies on what is called a GUID (global unique identifier). This is an identification number which is assigned to a customer at the time of registration, or when downloading a product. Many among the online community were alarmed when in 1999 it was discovered that Microsoft assigned GUIDS without their customer's knowledge. Following protests, the company was forced to change the registration procedure, assuring that under no circumstances would these identification numbers be used for tracking or marketing.

However, in the meantime, another possible infringement on user anonymity by Microsoft was discovered, when it as found out that MS Office documents, such as Word, Excel or Powerpoint, contain a bug that is capable of tracking the documents as they are sent through the net. The bug sends information about the user who opens the document back to the originating server. A document that contains the bug can be tracked across the globe, through thousands of stopovers. In detailed description of the bug and how it works can be found at the Privacy Foundation's website. Also, there is an example of such a bug at the Privacy Center of the University of Denver.

Of course there are many other ways of collecting users' data and creating appropriating data bodies which can then be used for economic purposes. Indeed, as Bill Gates commented, "information is the lifeblood of business". The electronic information networks are becoming the new frontier of capitalism.

Bureaucratic data bunkers



Among the foremost of the data bunkers government bureaucracies. Bureaucracies are the oldest forms of bunkers and are today deeply engrained in modern societies. Bureaucracies have always had the function of collecting and administering the data of subjects. What make this process more problematic in the age of ICT is that a lot more data can be collected, they can be collected in clandestine ways (e.g. in surveillance situations), and the can be combined and merged using advanced data mining technologies. In addition, there is a greater rationale for official data collecting, as a lot more data is required for the functioning of public administration as in previous periods, as societies rush to adopt increasingly complex technologies, above all ICTs. The increasing complexity of modern societies means that an increasing number of bureaucratic decision is taken, all of which require a calculation process. Complexity, viewed through government spectacles, generates insecurity - a great deal of the bureaucratic activity therefore revolves around the topic of security.

In spite of the anti-bureaucratic rhetoric of most governments, these factors provides the bureaucracies with an increased hold on society. Foremost bureaucratic data bunkers include the following:

    Law enforcement agencies

    Fiscal agencies

    Intelligence agencies

    Social welfare agencies

    Social insurance institutions

    Public health agencies

    Educational institutions



These are agencies that enjoy the privileged protection of the state. Those among them that operate in the field of security are further protected against public scrutiny, as they operate in an area to which democratic reason has no access.

What makes the data repositories of these institutions different from private data bunkers is their "official", i.e. their politically binding and definitive character. CAE speak of the bureaucracy as a "concrete form of uninterruptible, official and legitimised memory."

Iris recognition

Iris recognition relies upon the fact that every individuals retina has a unique structure. The iris landscape is composed of a corona, crypts, filaments, freckles, pits radial furrows and striatations. Iris scanning is considered a particularly accurate identification technology because the characteristics of the iris do not change during a persons lifetime, and because there are several hundred variables in an iris which can be measured. In addition, iris scanning is fast: it does not take longer than one or two seconds.

These are characteristics which have made iris scanning an attractive technology for high-security applications such as prison surveillance. Iris technology is also used for online identification where it can substitute identification by password. As in other biometric technologies, the use of iris scanning for the protection of privacy is a two-edged sword. The prevention of identity theft applies horizontally but not vertically, i.e. in so far as the data retrieval that accompanies identification and the data body which is created in the process has nothing to do with identity theft.

1980s: Artificial Intelligence (AI) - From Lab to Life

Following the commercial success of expert systems, which started in the 1970s, also other AI technologies began to make their way into the marketplace. In 1986, U.S. sales of AI-related hardware and software rose to U.S.$ 425 million. Especially expert systems, because of their efficiency, were still in demand. Yet also other fields of AI turned out to be successful in the corporate world.

Machine vision systems for example were used for the cameras and computers on assembly lines to perform quality control. By 1985 over a hundred companies offered machine vision systems in the U.S., and sales totaled U.S.$ 80 million. Although there was a breakdown in the market for AI-systems in 1986 - 1987, which led to a cut back in funding, the industry slowly recovered.

New technologies were being invented in Japan. Fuzzy logic pioneered in the U.S. and also neural networks were being reconsidered for achieving artificial intelligence. The probably most important development of the 1980s was, that it showed that AI technology had real life uses. AI applications like voice and character recognition systems or steadying camcorders using fuzzy logic were not only made available to business and industry, but also to the average customer.

The Copyright Industry

Copyright is not only about protecting the rights of creators, but has also become a major branch of industry with significant contributions to the global economy. According to the International Intellectual Property Alliance the U.S. copyright industry has grown almost three times as fast as the economy as a whole for the past 20 years. In 1997, the total copyright industries contributed an estimated US$ 529.3 billion to the U.S. economy with the core copyright industries accounting for US$ 348.4 billion. Between 1977 and 1997, the absolute growth rate of value added to the U.S. GDP by the core copyright industries was 241 %. Also the copyright industry's foreign sales in 1997 (US$ 66.85 billion for the core copyright industries) were larger than the U.S. Commerce Department International Trade Administration's estimates of the exports of almost all other leading industry sectors. They exceeded even the combined automobile and automobile parts industries, as well as the agricultural sector.

In an age where knowledge and information become more and more important and with the advancement of new technologies, transmission systems and distribution channels a further increase in the production of intellectual property is expected. Therefore as copyright establishes ownership in intellectual property it is increasingly seen as the key to wealth in the future.

Acessing the Internet

The Net connections can be based on wire-line and wireless access technolgies.

Wire-line access

Wire-less access

copper wires

Satellites

coaxial cables

mobile terrestrial antennas

electric power lines

fixed terrestrial antennas

fiber-optic cables







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 ISDN lines, etc., to an Internet Service Provider, from there, via fibre-optic cables, to the nearest Internet exchange, and on into a backbone network, tunneling across the continent und diving through submarine fibre-optic cables across the Atlantic to another Internet exchange, from there, via another backbone network and across another regional network to the Internet Service Provider of the supposed message recipient, from there via cables and wires of different bandwidth arriving at its destination, a workstation permanently connected to the Internet. Finally a sound or flashing icon informs your virtual neighbor that a new message has arrived.

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 Intelsat, Intersputnik and Inmarsat.

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.

Basics: Introduction

Copyright law is a branch of intellectual property law and deals with the rights of intellectual creators in their works. The scope of copyright protection as laid down in Article 2 of the 1996 WIPO Copyright Treaty "... extends to expressions and not to ideas, procedures, methods of operation or mathematical concepts as such." Copyright law protects the creativity concerning the choice and arrangement of words, colors, musical notes etc. It grants the creators of certain specified works exclusive rights relating to the "copying" and use of their original creation.

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 server. Therefore the Internet's architecture is called client-server architecture.

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 TCP/IP (Transmission Control Protocol / Internet Protocol).

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 gateways and might take a different route. It is not possible to determine in advance which ways these packets will take. At the receiving end the packets are checked and reassembled.

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 bandwidth needed is deployed on several packets sent on different routes. Detailed information about routing in the Internet can be obtained at http://www.scit.wlv.ac.uk/~jphb/comms/iproute.html.

One of the Internet's (and of the Matrix's) beginnings was the ARPANet, whose design was intended to withstand any disruption, as for example in military attacks. The ARPANet was able to route data around damaged areas, so that the disruption would not impede communication. This design, whith its origin in strategic and military considerations, remained unchanged for the Internet. Yet the design of the ARPANet's design cannot be completely applied to the Internet.

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.

Edward L. Bernays

Born 1891 in Vienna, Bernays was one of the founders of modern public relations. An enigmatic character, he was a master of mise en scène with far-reaching contacts in the world of business and politics. The nephew of Sigmund Freund and related with Heinrich Heine, he was also among the first to pursue PR for governments and to produce pseudo-events. Bernays considered the manipulation of public opinion as an important element of mass democracies and was of the opinion that only through PR a society's order can be kept.

Alan Turing

b. June 23, 1912, London, England
d. June 7, 1954, Wilmslow, Cheshire

English mathematician and logician who pioneered in the field of computer theory and who contributed important logical analyses of computer processes. Many mathematicians in the first decades of the 20th century had attempted to eliminate all possible error from mathematics by establishing a formal, or purely algorithmic, procedure for establishing truth. The mathematician Kurt Gödel threw up an obstacle to this effort with his incompleteness theorem. Turing was motivated by Gödel's work to seek an algorithmic method of determining whether any given propositions were undecidable, with the ultimate goal of eliminating them from mathematics. Instead, he proved in his seminal paper "On Computable Numbers, with an Application to the Entscheidungsproblem [Decision Problem]" (1936) that there cannot exist any such universal method of determination and, hence, that mathematics will always contain undecidable propositions. During World War II he served with the Government Code and Cypher School, at Bletchley, Buckinghamshire, where he played a significant role in breaking the codes of the German "Enigma Machine". He also championed the theory that computers eventually could be constructed that would be capable of human thought, and he proposed the Turing test, to assess this capability. Turing's papers on the subject are widely acknowledged as the foundation of research in artificial intelligence. In 1952 Alan M. Turing committed suicide, probably because of the depressing medical treatment that he had been forced to undergo (in lieu of prison) to "cure" him of homosexuality.

Codices, 1th century B.C.

The transformation of writings from scrolls to codices, in basic the hardcover book as we know it today, is an essential event in European history. Quoting accurately by page number, browsing through pages and skipping chapters, all impossible while reading scrolls, become possible.

In the computer age we are witnesses to a kind of revival of the scrolls as we scroll upwards and downwards a document we just see a portion of. Maybe the introduction of hypertext is the beginning of a similar change as the replacement of scrolls by codices.

Neural network

A bottom-up artificial intelligence approach, a neural network is a network of many very simple processors ("units" or "neurons"), each possibly having a (small amount of) local memory. The units are connected by unidirectional communication channels ("connections"), which carry numeric data. The units operate only on their local data and on the inputs they receive via the connections. A neural network is a processing device, either an algorithm, or actual hardware, whose design was inspired by the design and functioning of animal brains and components thereof. Most neural networks have some sort of "training" rule whereby the weights of connections are adjusted on the basis of presented patterns. In other words, neural networks "learn" from examples and exhibit some structural capability for generalization.

German Bundeswehr

The German contribution to the Western defence system, apart from playing host and contributing to the continued presence of allied troops on its soil, takes the form of its combined arm of defence known as the Federal Armed Forces (Bundeswehr). Constituting the largest contingent of NATO troops in Europe, the armed forces are divided into an army, navy, and air force. From its inception it was envisioned as a "citizens' " defence force, decisively under civilian control through the Bundestag, and its officers and soldiers trained to be mindful of the role of the military in a democracy. Conscription for males is universal, the military liability beginning at 18 and ending at 45 years of age.

First Amendment Handbook

The First Amendment to the US Constitution, though short, lists a number of rights. Only a handful of words refer to freedoms of speech and the press, but those words are of incalculable significance. To understand the current subtleties and controversies surrounding this right, check out this First Amendment site. This detailed handbook of legal information, mostly intended for journalists, should be of interest to anyone who reads or writes. For example, the chapter Invasion of Privacy shows the limits of First Amendment rights, and the balance between the rights of the individual and the rights of the public - or, more crudely, the balance of Tabloid vs. Celebrity. Each section is carefully emended with relevant legal decisions.

Josef Goebbels

Josef Goebbels (1897-1945) was Hitler's Minister for Propaganda and Public Enlightenment. He had unlimited influence on the press, the radio, movies and all kind of literary work in the whole Reich. In 1944 he received all power over the Total War. At the same time he was one of the most faithful followers of Hitler - and he followed him into death in 1945.

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).

Vladimir Putin is Russian President, Boris Yeltsin's. Until his appointment as Prime Minister in August 1999, he was nearly unknown. He had been working for the Soviet Security Service, the KGB. In July 1998 he took charge of the Federal Security Service, FSB. In March 1999 he became secretary of the Security Council. He has no experience in being at all. Where he demonstrated power until now is the Chechnya War. Soon after the beginning of this 2nd war in the region his popularity rose.

Joseph Stalin

Joseph Stalin (1879-1953):
After Lenin's death he took over and became a dictator without any limits of power. Everyone who dared to talk or act against him or was in suspicion of doing so, got killed. Millions were murdered. His empire was one made out of propaganda and fear. As long as he was in power his picture had to be in every flat and bureau. Soon after his death the cult was stopped and in 1956 the De-Stalination was started, though he was partly rehabilitated in 1970.

Galileo Galilee

Galileo Galilee (1564-1642), the Italian Mathematician and Physicist is called the father of Enlightenment. He proofed the laws of the free fall, improved the technique for the telescope and so on. Galilee is still famous for his fights against the Catholic Church. He published his writings in Italian instead of writing in Latin. Like this, everybody could understand him, which made him popular. As he did not stop talking about the world as a ball (the Heliocentric World System) instead of a disk, the Inquisition put him on trial twice and forbid him to go on working on his experiments.

Scientology

Official name Church Of Scientology, religio-scientific movement developed in the United States in the 1950s by the author L. Ron Hubbard (1911-86). The Church of Scientology was formally established in the United States in 1954 and was later incorporated in Great Britain and other countries. The scientific basis claimed by the church for its diagnostic and therapeutic practice is disputed, and the church has been criticized for the financial demands that it makes on its followers. From the 1960s the church and various of its officials or former officials faced government prosecutions as well as private lawsuits on charges of fraud, tax evasion, financial mismanagement, and conspiring to steal government documents, while the church on the other hand claimed it was being persecuted by government agencies and by established medical organizations. Some former Scientology officials have charged that Hubbard used the tax-exempt status of the church to build a profitable business empire.

Artificial intelligence approaches

Looking for ways to create intelligent machines, the field of artificial intelligence (AI) has split into several different approaches based on the opinions about the most promising methods and theories. The two basic AI approaches are: bottom-up and top-down. The bottom-up theory suggests that the best way to achieve artificial intelligence is to build electronic replicas of the human brain's complex network of neurons (through neural networks and parallel computing) while the top-down approach attempts to mimic the brain's behavior with computer programs (for example expert systems).

Oscar Wilde

Oscar Flingal O'Flahertie Wills (1854-1900) is one of the best and most famous poets and novelists of England of his time. His satirical and amusing texts exposed the false moral of the Bourgeoisie publicly. Besides, his life as a dandy made him the leader of aesthetics in England, until he was sent to prison because of homosexuality. Afterwards he lived in Paris where he died lonely and nearly forgotten in a hotel in 1900. His poems, fairy tales, novels and dramas survived.
