Question
How is the Sentinel LDK license system checking for cloned physical machines?
Answer
Our licensing system automatically applies the most appropriate clone protection scheme for physical machines for each end user based on various parameters. These can include:
| Criteria | Notes |
|---|---|
| CPU | CPU information. CPU UID is excluded |
| Ethernet address | MAC address |
| FQDN | Fully Qualified Domain Name. Not supported for Android |
| Hard disk | Hard disk ID (on a PC) or SD card ID (Android device) |
| IP address | IP address |
| Machine ID | Motherboard (on a PC) or Android serial number (or Android first boot if serial number is not available) |
| Security Identifier (SID) | Microsoft Windows Security Identifier (Windows machine only) |
The method employed by this scheme to protect against cloning of physical machines is effective for all types of physical machines commonly used by organizations.
