Abstract

Software activation and revalidation. In one example embodiment, a method for software activation and revalidation includes collecting machine configuration information from a machine on which a software application has been at least partially installed, sending the machine configuration information and a product key to an activation server, applying activation rules to determine whether the product key is valid for the machine configuration information, if the product key is valid for the machine configuration information, activating the software application by sending, from the activation server to the machine, license data that authorizes access to the software application and that contains the activation rules, periodically applying, at the machine, the activation rules to newly-collected machine configuration information to determine if the product key remains valid for the newly-collected machine configuration information, and if the product key remains valid, revalidating the license data to authorize continued access to the software application.

Claims

1. A method for software activation and revalidation, the method comprising:

collecting original machine configuration information from a machine on which a software application has been at least partially installed;

sending the original machine configuration information and a product key to an activation server;

applying, at the activation server, activation rules stored at the activation server to determine that the product key is valid for the original machine configuration information, the activation rules having been updated since the release of the software application to account for new or updated software or hardware with which the software application is configured to be employed;

activating the software application by sending, from the activation server to the machine, license data that authorizes access to the software application and that contains the updated activation rules;

collecting new machine configuration information from the machine, the new machine information being different from the original machine configuration information;

applying, at the machine, the updated activation rules contained in the license data to the new machine configuration information to determine that the product key remains valid for the new machine configuration information; and

revalidating, at the machine, the license data to authorize continued access to the software application.

2. The method as recited in claim 1, wherein the machine is a physical computer.

3. The method as recited in claim 1, wherein the machine is a virtual machine.

4. The method as recited in claim 1, wherein the original machine configuration information and the new machine configuration information include information regarding the operating system installed on the machine.

5. The method as recited in claim 4, wherein applying, at the activation server, the activation rules includes applying, at the activation server, the activation rules stored at the activation server to determine that the product key is valid for the operating system installed on the machine.

6. The method as recited in claim 1, wherein the license data is a signed license file to prevent a user of the machine from undetectably altering the updated activation rules contained in the signed license file.

7. The method as recited in claim 1, further comprising:

periodically reupdating the activation rules stored at the activation server; and

resending, from the activation server to the machine, the license data after each periodic reupdate, the license data containing the reupdated activation rules.

8. The method as recited in claim 1, wherein sending the original machine configuration information and the product key to the activation server includes sending the original machine configuration information and the product key to the activation server via an intermediate computer.

9. The method as recited in claim 1, wherein sending the license data from the activation server to the machine includes sending the license data from the activation server to the machine via an intermediate computer.

10. One or more non-transitory computer-readable media storing one or more programs that causes one or more processors to execute the method as recited in claim 1.

11. A method for software activation and revalidation, the method comprising:

collecting original machine configuration information from a local machine on which a software application has been at least partially installed;

sending the original machine configuration information and a product key to a remote activation server;

applying, at the remote activation server, activation rules stored at the remote activation server to determine that the product key is valid for the original machine configuration information, the activation rules having been updated since the release of the software application to account for new or updated software or hardware with which the software application is configured to be employed;

activating the software application by sending, from the remote activation server to the local machine, a signed license file that authorizes access to the software application and that contains the updated activation rules, the signing of the signed license file configured to prevent a user of the local machine from undetectably altering the updated activation rules contained in the signed license file;

collecting new machine configuration information from the local machine, the new machine information being different from the original machine configuration information;

applying, at the local machine, the updated activation rules contained in the signed license file to the new machine configuration information to determine that the product key remains valid for the new machine configuration information; and

revalidating, at the local machine, the signed license file to authorize continued access to the software application.

12. The method as recited in claim 11, wherein:

the original machine configuration information and the new machine configuration information include information regarding the operating system installed on the local machine; and

applying, at the remote activation server, the activation rules includes applying, at the remote activation server, the activation rules stored at the remote activation server to determine that the product key is valid for the operating system installed on the local machine.

13. The method as recited in claim 12, further comprising:

upgrading, subsequent to the activation of the software application, the operating system installed on the local installation computer to a different operating system; and

invalidating the signed license file after the upgrade of the operating system to prevent continued access to the software application because the product key is invalid for the different operating system.

14. The method as recited in claim 11, further comprising:

periodically reupdating the activation rules stored at the remote activation server; and

resending, from the remote activation server to the local machine, the signed license file after each periodic reupdate, the signed license file containing the reupdated activation rules.

15. The method as recited in claim 11, wherein sending the original machine configuration information and the product key to the remote activation server includes sending the original machine configuration information and the product key to the remote activation server via an intermediate local computer.

16. The method as recited in claim 11, wherein sending the signed license file from the remote activation server to the local machine includes sending the signed license file from the remote activation server to the local machine via an intermediate local computer.

17. The method as recited in claim 11, wherein applying, at the local machine, the updated activation rules contained in the signed license file includes applying, at the local machine, the updated activation rules contained in the signed license file each time that the software application is executed.

18. One or more non-transitory computer-readable media storing one or more programs that causes one or more processors to execute the method as recited in claim 11.
