Eliminating online censorship: Freenet, Free Haven and Publius |
 |
Protecting speech on the global data networks attracts an increasing attention. The efforts and the corresponding abilities of governmental authorities, corporations and copyright enforcement agencies are countered by similar efforts and abilities of researchers and engineers to provide means for anonymous and uncensored communication, as Freenet, Free Haven and Publius. All three of them show a similar design. Content is split up and spread on several servers. When a file is requested, the pieces are reassembled. This design makes it difficult to censor content. All of these systems are not commercial products.
The most advanced system seems to be Publius. Because of being designed by researchers and engineers at the prestigious  AT&T Labs, Publius is a strong statement against online censorship. No longer can it be said that taking a firm stand against the use of technologies limiting the freedom of individuals is a position of radical leftists only.
For more information on Publius, see John Schwartz, Online and Unidentifiable? in: The Washington Post, June 30, 2000,  http://www.washingtonpost.com/wp-dyn/articles/A21689-2000Jun29.html .

Invention
According to the WIPO an invention is a "... novel idea which permits in practice the solution of a specific problem in the field of technology." Concerning its protection by law the idea "... must be new in the sense that is has not already been published or publicly used; it must be non-obvious in the sense that it would not have occurred to any specialist in the particular industrial field, had such a specialist been asked to find a solution to the particular problem; and it must be capable of industrial application in the sense that it can be industrially manufactured or used." Protection can be obtained through a patent (granted by a government office) and typically is limited to 20 years.
