Copyright Management and Control Systems: Pre-Infringement

Pre-infringement copyright management and control systems that inhibit or control infringement of intellectual property may be put into place by copyright owners before distributing their works. Examples are:

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.

Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks

This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network.

Chappe's fixed optical network

Claude Chappe built a fixed optical network between Paris and Lille. Covering a distance of about 240kms, it consisted of fifteen towers with semaphores.

Because this communication system was destined to practical military use, the transmitted messages were encoded. The messages were kept such secretly, even those who transmit them from tower to tower did not capture their meaning, they just transmitted codes they did not understand. Depending on weather conditions, messages could be sent at a speed of 2880 kms/hr at best.

Forerunners of Chappe's optical network are the Roman smoke signals network and Aeneas Tacitus' optical communication system.

For more information on early communication networks see Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks.

Royal Dutch/Shell Group

One of the world's largest corporate entities in sales, consisting of companies in more than 100 countries, whose shares are owned by NV Koninklijke Nederlandsche Petroleum Maatschappij (Royal Dutch Petroleum Company Ltd.) of The Hague and by the "Shell" Transport and Trading Company, PLC, of London. Below these two parent companies are two holding companies, Shell Petroleum NV and the Shell Petroleum Company Limited, whose shares are owned 60 percent by Royal Dutch and 40 percent by "Shell" Transport and Trading. The holding companies, in turn, hold shares in and administer the subsidiary service companies and operating companies around the world, which engage in oil, petrochemical, and associated industries, from research and exploration to production and marketing. Several companies also deal in metals, nuclear energy, solar energy, coal, and consumer products.
