Abstract

A method and apparatus of encouraging distribution, registration, and purchase of free copyable software and other digital information which is accessed on a User'"'"'s System via a Programmer'"'"'s Program. Software tools which can be incorporated into a Programmer'"'"'s Program allow the User to access Advanced Features of the Programmer'"'"'s Program only in the presence of a valid Password which is unique to a particular Target ID generated on an ID-Target such as the User'"'"'s System. Advanced features will thus relock if the Password is copied to another ID-target. If a valid Password is not present, the User is invited to obtain one, and provided with the means of doing so, and of installing that Password in a place accessible to the User'"'"'s System on subsequent occasions. The present invention also provides Programmers with means to invoke business operations as well as computational operations with their programs, and thus to automatically obtain payment from Users who elect to obtain passwords.

13. The method as recited in claim 12, wherein the entity is the computer.

14. The method of claim 13, wherein the identifier is based at least in part on one or more characteristics of a device accessible to the computer.

15. The method of claim 13, wherein the identifier is based at least in part on a characteristic of hardware of the computer.

16. The method of claim 13, wherein the identifier is based at least in part on a characteristic of a user of the computer.

17. The method of claim 13, wherein the identifier is based at least in part on one or more adequately unique characteristics of the computer.

18. The method of claim 13, wherein the computer generates the identifier.

19. The method of claim 12, wherein the password is generated by using the identifier as a seed to a number generator.

21. The method of claim 13, wherein the identifier is based on a software-accessible characteristic of the computer selected from the group consisting of:

the number of one or more peripherals to the computer, a kind of the one or more peripherals, the number of one or more CPUs in the computer, a kind of the one or more CPUs, an interleave factor, and one or more timing characteristics of the computer.

22. The method of claim 13, wherein the identifier is based at least in part on a characteristic of a user of the computer.

23. The method of claim 12, wherein the identifier is based on a voice pattern of the user.

24. The method of claim 12, wherein the first identifier is based on the text information.

25. A method for operating a licensing server to distribute passwords to a plurality of users to access text files at remote computers, the method comprising:

receiving, at a licensing server, a first identifier associated with a request for access to a text file, the request generated by a first program at a first remote computer, the first identifier being based at least in part on one or more characteristics of an entity to which access to the text file is linked, the first identifier being previously unknown to the licensing server;

generating, at the licensing server, a password based at least in part on the first identifier; and

transmitting the password to a first location accessible to the first remote computer.

26. The method of claim 25, wherein receiving the first identifier comprises receiving the first identifier from a user previously unknown to the licensing server.

27. The method of claim 25, wherein generating a password comprises generating a password which may only be validated using at least data accessible to the first remote computer including the first identifier.

28. The method of claim 25, wherein generating a password comprises generating a password using a technique which does not require any additional information that is characteristic of the entity.

29. The method of claim 25, wherein the request comprises a request including payment information associated with access to the text file.

30. The method of claim 29, wherein the payment information is related to a monetary payment.

31. The method of claim 29, further comprising crediting or transferring, to an account dedicated to a party associated with programming at least one of the text file and the first remote computer.
