Anti-piracy protection service-based software license management system to prevent usage of unlicensed software after the trial period
One example method, includes checking, by an intelligent time detector service running on a computing system, a trial period duration of software on the computing system, starting, by the intelligent time detector service, a counter for the software, and the counter is operable to generate a counter value based on a clock of the computing system, storing, by the intelligent time detector service, a counter value of the counter, and decommissioning, by the intelligent time detector service, the software after the trial period has expired.
1. A method, comprising operations of:
checking, by an intelligent time detector service running on a computing system, a trial period duration of software on the computing system;
starting, by the intelligent time detector service, a counter for the software, and the counter is configured to generate a counter value based on a clock of the computing system;
storing, by the intelligent time detector service, a counter value of the counter, wherein an accuracy of the counter value is maintained notwithstanding a change to the system clock; and
when the counter value reaches the trial period duration, decommissioning, by the intelligent time detector service, the software after the trial period has expired,
wherein the intelligent time detector service prevents tampering with the counter and counter value.
2. The method as recited in claim 1 , wherein the counter value is encrypted by a Trusted Platform Module (TPM) module prior to being stored.
3. The method as recited in claim 1 , wherein the intelligent time detector service calculates a time interval between a power-down and power-up of the computing system, and the intelligent time detector service updates the counter using the time interval.
4. The method as recited in claim 1 , wherein the counter is triggered to start by downloading of the software to the computing system has been completed, or is triggered by installation of the software on the computing system.
5. The method as recited in claim 1 , wherein a user of the computing system and/or a vendor of the software are notified when the trial period has expired.
6. The method as recited in claim 1 , the intelligent time detector service prevents reinstallation of the software after the trial period has expired.
7. The method as recited in claim 1 , wherein the intelligent time detector service increments the counter based on the system clock.
8. The method as recited in claim 1 , wherein the intelligent time detector system encrypts software expiration information and software uninstallation information.
9. A computer readable storage medium having stored therein instructions that are executable by one or more hardware processors to perform operations comprising:
checking, by an intelligent time detector service running on a computing system, a trial period duration of software on the computing system;
starting, by the intelligent time detector service, a counter for the software, and the counter is configured to generate a counter value based on a clock of the computing system;
storing, by the intelligent time detector service, a counter value of the counter, wherein an accuracy of the counter value is maintained notwithstanding a change to the system clock; and
when the counter value reaches the trial period duration, decommissioning, by the intelligent time detector service, the software after the trial period has expired,
wherein the intelligent time detector service prevents tampering with the counter and counter value.
10. The computer readable storage medium as recited in claim 9 , wherein the counter value is encrypted by a Trusted Platform Module (TPM) module prior to being stored.
11. The computer readable storage medium as recited in claim 9 , wherein the intelligent time detector service calculates a time interval between a power-down and power-up of the computing system, and the intelligent time detector service updates the counter using the time interval.
12. The computer readable storage medium as recited in claim 9 , wherein the counter is triggered to start by downloading of the software to the computing system has been completed, or is triggered by installation of the software on the computing system.
13. The computer readable storage medium as recited in claim 9 , wherein a user of the computing system and/or a vendor of the software are notified when the trial period has expired.
14. The computer readable storage medium as recited in claim 9 , the intelligent time detector service prevents reinstallation of the software after the trial period has expired.
15. The computer readable storage medium as recited in claim 9 , wherein the intelligent time detector service increments the counter based on the system clock.
16. The computer readable storage medium as recited in claim 9 , wherein the intelligent time detector system encrypts software expiration information and software uninstallation information.
