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

transmitting the identifier to a licensing processor;

receiving a password, based at least in part on the identifier, that links access to the one or more items of audio information to the entity, the password generated using a technique which does not use any additional characteristic of the entity; and

invoking a password validator to access the identifier to validate the password, and to permit access to a selected one of the one or more items of audio information when the password is validated.

11. The method of claim 10, wherein the entity is the audio processing system.

12. The method of claim 11, wherein the identifier is based on one or more characteristics of a device accessible to the audio processing system.

13. The method of claim 11, wherein the identifier is based on a characteristic of hardware of the audio processing system.

14. The method of claim 10, wherein the identifier is based at least in part on a characteristic of a user of the audio processing system.

15. The method of claim 10, wherein the identifier is based at least in part on one or more adequately unique characteristics of the audio processing system.

16. The method of claim 11, wherein the audio processing system generates the identifier.

17. The method of claim 10, wherein the password is generated using the identifier as a seed to a number generator.

18. The method of claim 11, wherein the identifier is based on a software-accessible serial number for the audio processing system.

19. The method of claim 11, wherein the identifier is based on a software-accessible characteristic of the audio processing system selected from the group consisting of:

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

20. The method of claim 10, further comprising:

playing the selected audio information at less than full fidelity in absence of a validated password; and

playing the selected audio information at full fidelity when the password is validated.

21. A method for operating a licensing server, the licensing server communicating over a communications network with one or more programs residing on one or more remotely located user audio processing systems, to distribute passwords to a plurality of users to access one or more audio recordings at the remotely located user audio processing systems, the method comprising:

receiving, at a licensing server, an identifier previously unknown to the licensing server and associated with a request to access one or more audio recordings, the request having been generated by a program at a remotely located audio processing system, the identifier being based at least in part on one or more characteristics of an entity to which access to the audio recording is linked, such one or more characteristics excluding any characteristic of a generator generating the identifier, different such one or more characteristics being usable to link access to different ones of the one or more audio recordings;

generating, at the licensing server, a password, based at least in part on the identifier, that links access to the one or more audio recordings to the entity; and

transmitting the password over a communications network to a location accessible to the remotely located audio processing system.

22. The method of claim 21, comprising receiving the identifier from a user previously unknown to the licensing server.

23. The method of claim 21, wherein the password is validated using at least data accessible to the remotely located audio processing system including the identifier.
