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
Under this approach copyright owners would commission "clearinghouses" with the ability to license the use of their works. A user would pay a license fee to obtain rights concerning the intellectual property.

Powerful and controversial director of the U.S. Central Intelligence Agency (CIA) from 1981 to 1987 during the Ronald Reagan administration. While affiliated with the law firm Rogers & Wells (1976-81), Casey became Reagan's presidential campaign manager and was subsequently awarded the directorship of the CIA in 1981. Under his leadership, covert action increased in such places as Afghanistan, Central America, and Angola, and the agency stepped up its support for various anticommunist insurgent organizations. He was viewed as a pivotal figure in the CIA's secret involvement in the Iran-Contra Affair, in which U.S. weapons were sold to Iran and in which money from the sale was funneled to Nicaraguan rebels, in possible violation of U.S. law. Just before he was to testify in Congress on the matter in December 1986, he suffered seizures and then underwent brain surgery; he died from nervous-system lymphoma without ever testifying.

English mathematician who helped establish modern symbolic logic and whose algebra of logic, now called Boolean algebra, is basic to the design of digital computer circuits. One of the first Englishmen to write on logic, Boole pointed out the analogy between the algebraic symbols and those that can represent logical forms and syllogisms, showing how the symbols of quantity can be separated from those of operation. With Boole in 1847 and 1854 began the algebra of logic, or what is now called Boolean algebra. It is basically two-valued in that it involves a subdivision of objects into separate classes, each with a given property. Different classes can then be treated as to the presence or absence of the same property.
