Along with the rapid growth of Wi-Fi-enabled smartphone devices, the need for efficient content sharing techniques for smartphones in Wi-Fi environment has increased. There are many methods recently presented by various researchers for efficient content sharing in Smartphones. However existing methods are suffered from the various limitations. Hence, this area of research is still thought provoking problem for researchers. This paper present secure approach for message passing and content sharing in Smartphones using Wi-Fi (WCS), which gives better speed and range over Bluetooth and no internet connection or heavy centralized servers, are required in this process. Each smartphone can work as client and server at the same time. Message passing is done securely by using encryption decryption technique.
