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 re-lock 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.

Claims

1. A method for providing a password to a first program to control access to protected information, the method comprising:

receiving a first identifier, the first identifier being based at least in part on one or more characteristics of an entity to which access to the protected information is linked;

generating a password, based at least in part on the first identifier, which password may only be validated using at least data accessible to the first program including the first identifier; and

storing the password in a first location accessible to the first program.

2. The method of claim 1, comprising the first program using the stored password to control access to the protected information.

3. The method of claim 1, wherein the first identifier is based on one or more characteristics of a first device accessible to the first program.

4. The method of claim 3, wherein the first identifier is based on one or more characteristics of a first device on which the first program resides.

5. The method of claim 3, wherein the first identifier is based on a characteristic of hardware in the first device.

6. The method of claim 5, wherein the first identifier is based on a software-accessible serial number for hardware in the first device.

7. The method of claim 5, wherein the first identifier is based on a software-accessible characteristic of the first device selected from the group consisting of:

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

10. The method of claim 1, wherein the first identifier is based at least in part on one or more adequately unique characteristics of the entity.

11. The method of claim 1, comprising generating the first identifier on a first device.

12. The method of claim 11, wherein generating the first identifier is performed on a first device on which the first program resides.

13. The method of claim 11, wherein generating is performed on a first device separate from a second device on which the first program resides.

14. The method of claim 11, wherein the first device is located remotely from a second device on which the password is generated.

15. The method of claim 14, comprising directly or indirectly transmitting the first identifier from the first device to the second device.

16. The method of claim 14, comprising transmitting the generated password from the second device to the first device.

17. The method of claim 12, wherein generating the first identifier is performed after installation of the first program on the first device.

18. The method of claim 1, wherein the data includes only the first identifier.

19. The method of claim 1, wherein generating the password is performed using a licensing processor.

20. The method of claim 1, wherein generating the password comprises using the first identifier as a seed to a number generator.

21. The method of claim 20, wherein the number generator is a random number generator.

22. The method of claim 20, comprising validating the password by using the first identifier as a seed to the number generator.

23. The method of claim 1, wherein storing the password comprises storing the password on a first device on which the first program resides.

24. The method of claim 1, wherein storing the password comprises storing the password on a first device separate but accessible from a second device on which the first program resides.

25. The method of claim 1, wherein storing the password comprises storing the password in copy-protected form.

26. The method of claim 1, wherein storing the password comprises storing the password in a first location hidden from a user but accessible to the first program.

8. The method of 1, wherein the first identifier is based at least in part on a characteristic of a user of the first program.

9. The method of claim 8, wherein the first identifier is based on a voice pattern of the user.

27. A method for providing a password to a first program to access protected information, the method comprising:

a user processor generating a first identifier using information about the user processor;

transmitting the first identifier from the user processor to a licensing processor;

the licensing processor generating a password, based at least in part on the first identifier, which password may only be validated using at least data accessible to the first program including the first identifier; and

transmitting the generated password from the licensing processor to the user processor.

28. A method for controlling access to protected information using a first program, the method comprising:

generating a first identifier, the first identifier being based at least in part on one or more characteristics of an entity to which access to the protected information is linked;

transmitting the first identifier to a licensing processor;

receiving a password based at least in part on the first identifier, which password may only be validated using at least data accessible to the first program including the first identifier; and

storing the password in a first location accessible to the first program.
