Hardware Devices
Those have to be acquired and installed by the user. For example under a debit card approach, the user purchases a debit card that is pre-loaded with a certain amount of value. After installation, the debit card is debited automatically as the user consumes copyrighted works.
Digital Certificates
Hereby a certification authority issues to a user an electronic file that identifies the user as the owner of a public key. Those digital certificates, besides
Centralized Computing
Under this approach all of the executables remain at the server. Each time the executable is used, the user's computer must establish contact with the server, allowing the central computer to meter access.
Access Codes
Access code devices permit users to "unlock" protective mechanisms (e.g. date bombs or functional limitations) embedded in copyrighted works. Copyright owners can meter the usage of their works, either by unlocking the
Copyright Clearinghouses

Only in Roman times the first rights referring to artistic works appeared. Regulations resembling a lasting exclusive right to copy did not occur until the 17th century. Before copyright was a private arrangement between guilds able to reproduce copies in commercial quantities.
In France and Western European countries "droits d'auteur" or author's rights is the core of what in the Anglo-American tradition is called copyright. Such rights are rooted in the republican revolution of the late 18th century, and the Rights of Man movement. Today in the European system the creator is front and center; later exploiters are only secondary players.
France
During the 18th century France gradually lost the ability to restrict
In 1777 the King threatened the monopoly by reducing the duration of publisher's privileges to the lifetime of the authors. Accordingly a writer's work would go into the public domain after his death and could be printed by anyone. The booksellers fought back by argumenting that, no authority could take their property from them and give it to someone else. Seven months later, in August 1789, the revolutionary government ended the privilege system and from that time on anyone could print anything. Early in 1790 Marie-Jean-Antoine-Nicolas de Caritat, Marquis de Condorcet proposed giving authors power over their own work lasting until ten years after their deaths. The proposal - the basis for France's first modern copyright law - passed in 1793.

The MIT (Massachusetts Institute of Technology) is a privately controlled coeducational institution of higher learning famous for its scientific and technological training and research. It was chartered by the state of Massachusetts in 1861 and became a land-grant college in 1863. During the 1930s and 1940s the institute evolved from a well-regarded technical school into an internationally known center for scientific and technical research. In the days of the Great Depression, its faculty established prominent research centers in a number of fields, most notably analog computing (led by
