Abstract (en)
[origin: WO2006053631A1] The aim of the invention is to provide a method for managing a time-limited license on a computer application that can be run on a network component, during which it is ensured that a computer application is reliably rendered unavailable for continued unauthorized use once the duration of the license has expired. To this end, a method is provided during which: a) a license data record (LF) is created that contains at least the information concerning the computer application to be licensed, a license period and a signing time (CD); b) the license data record (LF) is read from a license server (LS), and based on the information concerning the signing time (CD), a reference date (RD) is determined for this computer application; c) the reference date (RD) is compared with a system time (SC), which is defined for the network component (KE), in order to determine a current time base for the license server (LS); d) Based on this comparison, it is determined whether the computer application is run on the basis of the current time base and/or on the basis of the granted license period (LP), whereby; e) the reference date (RD) is continuously updated and stored on the license server (LS). In this manner, the inventive method, together with the license server that, itself, can be run on the network component, enables, based on the determination of the reference date and based on the continuous updating thereof, a creation of the time base, which is independent of the system time and against which the assured license period can be evaluated.
