By setting up a dongle on the service side host, the present invention allows multiple client side hosts connected to the service side host to share a software protection product (a dongle herein) and due to the key information of the protected software is stored within the dongle, the client side hosts must interact with the dongle to operate the software properly. The access from the client side is controlled and monitored by the service side. The individual clients can share a dongle to use the protected software respectively. Besides protecting the software, the number of the software protection apparatuses in use is reduced by sharing them, so that the cost is reduced as a result. The centralized management and control of the service side make it possible for the clients to access the dongle in a time-sharing manner. The clients can continually interact with the dongle or stop using the software according to the response from the dongle.
