Systems and methods for implementing a hardware ID with time- and
weight-based flexibility use a hardware ID (HWID) including identifying
information about hardware components. When software is run, a current
HWID is generated. When the current HWID is compared to a stored HWID to
determine if the two HWIDs match, a time vector and a weight vector are
used in the comparison. A running matching score is kept of matches. For
each hardware component, the weight vector indicates the weight given to
a correct match of the hashed value for the hardware component. For
example, if the weight value for the hardware component is three and
there is a match, then the running total is increased by three. For each
hardware component, the time vector may indicate an expiration period
after which a change in the component may be allowed. For example, if the
expiration period for the component is one year, and one year has passed
since activation, the running total may be increased even though the
component's information in the verification HWID does not match the
current component information.
