 Software licenses are usually tied to both a user of the software, and some number of computer systems that the software will be installed onto. In order to enforce the installation limit, one or more metrics of the computer system must be fingerprinted to validate that the user did not attempt to impermissibly transfer the software from one computer to another. Together, these collected metrics form what is called a "fingerprint". Software licenses are usually tied to both a user of the software, and some number of computer systems that the software will be installed onto.

 +Some metrics can change over the lifetime of a single installation. For example, the operating system version, processor, motherboard, storage volume identifier, etc. Generally, some components of a fingerprint are allowed to change as long as the remainder of the fingerprint remains the same, allowing a sort of "Ship of Theseus" style evolution of the fingerprint. The goal is to prevent the software from losing its license authorization because of regular maintenance of the system (like replacing a failed hard drive, upgrading the CPU and/or motherboard, upgrading the OS) while still preventing the software from being copied to a new system entirely.
