<p>Methods and systems disclosed herein may be used to determine if licensed software has been previously installed or used on a device by monitoring an identifier associated with the device on which the licensed software is to be installed or used. Prior to operation of licensed software, a client device requires authorization from a license server. The license server may retrieve a unique identifying device fingerprint from the client device to authorize installation of the software based on a probabilistic comparison of the identifier with stored device identifiers subject to a license. If the comparison yields a match and if total instances of retrieval of the retrieved device fingerprint does not exceed licensed rights, the authorization is granted.</p> |
