cryptography:
It is the study of encryption, the art/science to create and use codes and/or ciphers with the purpose of enciphering as well as deciphering.
After a relatively vivid but slow development of cryptography for nearly 4.000 years the inventions of the telegraph, radio and computer had a high impact on the velocity of further inventions concerning encryption.
Most of the time economic, political or military reasons lie behind the necessity of encryption. As visible from the timetable cryptography it is also done for private and individual interests. An extraordinary example for this is the Braille Code, developed as a possibility for blind people to read and write.
A lot of very interesting and intelligent websites about cryptography can be found in the Internet.Some websites offering links to various cryptography-websites are:
Further there exists a wide range of web-magazines/newsletters/mailing lists on cryptography, e.g.:
Crypto-Gram Newsletter:
Journal of Computer Security:

Agencies like the NSA are currently able to eavesdrop on anyone with few restrictions only - though other messages are spread by the NSA.
Theoretically cryptography can make that difficult. Hence those agencies speak up for actions like introducing trapdoors to make it possible to get access to everybody's data.
See the U.S. discussion about the Clipper Chip some years ago:
While encryption offers us privacy for the transmission of data, we do not only wish to have it but also need it if we want to transport data which shall not be seen by anyone else but the recipient of our message. Given this, the governments and governmental institutions/organizations fear to lose control. Strict laws are the consequence. The often repeated rumor that the Internet was a sphere of illegality has been proven wrong. Some parts are controlled by law very clearly. One of them is cryptography. Prohibition of cryptography or at least its restriction are considered an appropriate tool against criminality. Or one should say: had been considered that. In the meantime also governmental institutions have to admit that those restrictions most of all work against the population instead against illegal actors. Therefore laws have been changed in many states during the last five years. Even the USA, the Master of cryptography-restriction, liberated its laws in December 1999 to be more open-minded now.

Intellectual property, very generally, relates to the output that result from intellectual activity in the industrial, scientific, literary and artistic fields. Traditionally intellectual property is divided into two branches: 1) industrial property (
Critical Art Ensemble is a collective of five artists of various specializations dedicated to exploring the intersections between art, technology, radical politics, and critical theory. CAE have published a number of books and carried out innovative art projects containing insightful and ironic theoretical contributions to media art. Projects include Addictionmania, Useless Technology, The Therapeutic State, Diseases of Consciousness, Machineworld, As Above So Below, and
