Method and arrangement for protecting software
First Claim
1. A method of limiting the number of simultaneous users of a software protected by a licence agreement, wherein the software can be activated by a plurality of network connected workstations, characterised by the following steps:
- A) sending a start request from the software to a network connected central lock unit as the software is activated by a workstation, wherein at least one physical licence unit, associated with the protected software and containing a readable unique identity code, is connected to the lock unit and has a limited number of user positions which can be occupied by users of the software, B) investigating whether any licence unit, connected to the lock unit and associated with the software, has any free user position, C) starting the software for usage in said workstation if a free user position is found in step b), and D) terminating the software if no free user position is found in step B).

Abstract
A method and arrangement for limiting the number of simultaneous users of a software (106) protected by a licence agreement. A start request is sent from the software to a lock unit (108) when the software is activated by a workstation (102), after which it is investigated whether any physical licence unit (110), connected to the lock unit and corresponding to the software, has a free user position. The software is started if there is a free user position, but is terminated if there is free user position. The solution provides for increased control and security that the number of simultaneous users cannot exceed what is covered by the licence agreement, as well as a simple upgrading of licence agreements.
