Abstract

Methods and systems to control a license for a software application are disclosed. The methods and systems can include requesting a central licensing server for initial verification and authentication of at least one user of a software application and sending a identification application from the central licensing server to at least one of the first device or the second device. A license identifier can be generated in the first device or the second device and sent to the central licensing server. The central licensing server can respond by sending a license key generator program to generate a dynamic key. The dynamic key can be input in the second device to execute the software application.

Claims

1. A method of enforcing a usage agreement for a software application, the method comprising:

receiving a copy of the software application on a first device, the software application including license verification software which requests verification of a right of a user to use the software application before allowing the user to use the software application;

submitting a license identification to a central licensing server; and

receiving, from the central licensing server, a license key generator program, which, when executed on the second device, provides a license key, which, when input into the license verification software on first device, allows usage of the software application by the user.

2. The method of claim 1, wherein the second device is a mobile device.

3. The method of claim 2, wherein the first device is a fixed device.

4. The method of claim 1, wherein the received copy of the software application is associated with a license identifier and wherein the license identification submitted to the central licensing program includes the license identifier.

5. The method of claim 4, further comprising receiving, from the central licensing server, a license identification program, which, when executed, causes the device to generate the license identification and to submit the license identification to the central licensing server.

6. The method of claim 5, wherein the license identification program is received and executed on the second device.

7. The method of claim 5, wherein the license identification program is received and executed on the first device.

8. The method of claim 5, wherein the license identification also includes a unique identifier for the second device.

9. The method of claim 8, wherein the second device is a mobile telephone and the unique identifier for the second device comprises an International Mobile Equipment Identity number.

10. The method of claim 8, wherein the copy of the software application includes a license certificate file.

11. The method of claim 10, wherein license keys generated by the license code generator program include an encrypted version of the license certificate file encrypted with a license encryption key which is known by the copy of the software application.

12. The method of claim 11, wherein the license encryption key is received from the central licensing server along with the license key generator program.

13. The method of claim 12, wherein the license encryption key is itself encrypted using a key based at least in part on the unique identifier for the second device.

14. The method of claim 10, wherein the license certificate file comprises a signer certificate or license criteria or a combination thereof.

15. The method of claim 1, wherein the license key is manually input into the first device.

16. The method of claim 1, wherein the license key is electronically transmitted to the first device.

17. The method of claim 1, wherein the license key is provided to the central licensing server in addition to being provided to the first device.

18. The method of claim 1, further comprising, before downloading the license verification software verifying whether the user currently has permission to use the software application, and if the user currently has permission, allowing the user to use the software application without performing the other steps.

19. The method of claim 1, wherein each license key produced by the license key generator program is generated only once.

20. The method of claim 19, wherein, if the license key generator program cannot produce any more license keys, a new license key generator program is received from the central licensing server.

21. The method of claim 14, wherein the usage agreement for the software application includes at least one of a subscription agreement, a rental agreement, or a trial agreement.

22. A system for providing licenses for a software application, the system comprising:

a license storage containing a plurality of license certificate and encryption key pairs, each assigned a unique license identifier;

a license verification software module, configured to verify if a user currently has permission to use an installed copy of the software application; and

a license key generator program generator module, configured to generate license key generator software for a first device upon receiving an identifier of the computer along with an identifier of a license and encryption key pair.

23. The system of claim 22, further comprising a license certificate and encryption key generator, which is configured to generate license and encryption key pairs and to store these pairs in the license storage.

24. The system of claim 22, further comprising a software distribution module configured to distribute copies of the software application, each copy of the software application including a license certificate and a unique license identifier.

25. The system of claim 22, wherein the license verification software module is configured to send a license identification program to the first device, the license identification program configured to generate value comprising a unique license identifier as well as an identifier of the first device.

26. The system of claim 22, wherein the first device is a mobile device and the software application is used on a computer.

27. The system of claim 22, wherein license verification software module is configured to determine if a maximum period of time for the user to use the software has passed.

28. One or more computer-readable media containing instructions, which, when executed on a first computer device, perform a method on the first device for authorizing a user to execute a software application on second device, the method comprising:

generating a license identifier;

providing the license identifier to the second computer device;

generating a dynamic license key in the first device using a license key generation application received from a central licensing server; and

providing the dynamic license key to the second device to allow execution of the software application;

wherein, a new dynamic key is generated every time the license key generation application is executed in the first computer device.

29. A method of enforcing a usage agreement for a software application, the method comprising:

generating a license certificate and encryption key;

storing the license certificate and encryption key as a pair;

generating a copy of a software application including license verification software which requests verification of a right of a user to use the software application before allowing the user to use the software application and a copy of the generated license certificate;

receiving a copy of the software application on a fixed device;

receiving a copy of an identifying application to a mobile device;

after executing the identifying application on the mobile device, submitting a license identification comprising an identifier of the generated license certificate and a unique identifier for the mobile device to a central licensing server;

generating a license key generator program at the central licensing server, the license key generator program configured to, when executed on the mobile device, provide a license key, which, when input into the license verification software on first device, allows usage of the software application by the user

receiving, from the central licensing server, the generated license key generator program; and

inputting the license key into the software application to use the software application.
