  • System for securing protected software from unauthorized use in computer networks
    Patent number: 6101606
    Abstract: The invention relates to a system for securing protected software against unauthorized, i.e. non-licensed, use in computer networks. The difficulty in licensing of software in a network is that simultaneous and multi-use of the licensed software on several or all computers integrated in the network have to be realized. Without software protection the software producer will lose potential customers. This concerns local networks as well as so-called wide area networks which can be operated across national or continental boundaries.
