Introduction

"A man is crazy who writes a secrete
in any other way than one which
will conceal it from the vulgar."
Roger Bacon (~1250 AD)



The essence of human communication is not only the social behavior to give or get messages (of whatever meaning) but also how to give and get them, and to include certain people by excluding others from the process of informing.
e.g. whispering is an effective way of talking to exclude the majority.
What about ways of writing?
Already some of the first written messages in human history obviously found special forms of hiding contents from the so-called others. When the knowledge of writing meant a privilege in a stronger sense as it is true today (in China for a long period writing was forbidden to people not working for the government), the alphabet itself was a kind of cryptography (that is why Catholic churches were painted with pictures explaining the stories of the Bible).

Certainly the methods of deciphering and enciphering improved a lot during the last 4.000 years. In the meantime cryptography has become a topic without end and with less technological limits every day. On the one hand there is the field of biometrics, which is highly related to cryptography but still in its beginnings, on the other hand there emerge so-called infowars, which intend to substitute or at least accompany war and are unthinkable without cryptography.
But there is much more to detect, like the different forms of de- and encoding. And very important, too, there is the history of cryptography that tells us about the basics to make it easier to understand today's issues.

In the actual age of (dis-)information storing and transporting electronic information safely increases its importance. Governments, institutions, economy and individuals rely on the hope that no-one can read or falsify their messages/data as it is much more difficult to detect and proof abuses in electronic media than in elder forms of written communication.

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.

Framing

Framing is the practice of creating a frame or window within a web page where the content of a different web page can be display. Usually when a link is clicked on, the new web page is presented with the reminders of the originating page.

Fair use

Certain acts normally restricted by copyright may, in circumstances specified in the law, be done without the authorization of the copyright owner. Fair use may therefore be described as the privilege to use copyrighted material in a reasonable manner without the owner's consent and allows the reproduction and use of a work for limited purposes such as criticism, comment, news reporting, teaching, and research. To determine whether a use is fair or not most copyright laws consider: 1) purpose and character of the use, 2) nature of the copyrighted work, 3) amount and substantiality of the portion used, and 4) effect of the use on the potential market. Examples of activities that may be excused as fair use include: providing a quotation in a book review; distributing copies of a section of an article in class for educational purposes; and imitating a work for the purpose of parody or social commentary.

Java Applets

Java applets are small programs that can be sent along with a Web page to a user. Java applets can perform interactive animations, immediate calculations, or other simple tasks without having to send a user request back to the server. They are written in Java, a platform-independent computer language, which was invented by Sun Microsystems, Inc.

It is a system, where letters get converted into numeric characters.
The numbers were not written down and sent but signaled with torches.

for example:
A=1-1
B=1-2
C=1-3
W=5-2

The World Wide Web History Project

The ongoing World Wide Web History Project was established to record and publish the history of the World Wide Web and its roots in hypermedia and networking. As primary research methods are used archival research and the analysis of interviews and talks with pioneers of the World Wide Web. As result a vast of collection of historic video, audio, documents, and software is expected. The project's digital archive is currently under development.
