A robust approach to prevent software piracy

Software piracy is a main concern in today's world. Many techniques are proposed and implemented to stop it. In this paper we are refining a newly proposed technique “Software Piracy Prevention through SMS Gateway” to make it more stable and effective against piracy. The targeted approach is based on SMS gateway service to install software on a system, but the technique left some problems untouched i.e. issues related to MAC address, time offset and Man in the middle attack (MiTM) [1]. In refined approach the server will initiate authentication process instead of client at regular time intervals, and this facility increase the effectiveness of the technique.
