Child abuse is any action by a perpetrator that causes intentional harm to a child. Security systems must be designed to defend children from such difficult situations. The advancement in wearable sensor technology, tracking mechanisms, wireless communication protocols allows for development of smart systems that detect and prevent child abuse. In this paper, we have reviewed various technologies that are supporting to the human safety and security systems such as Wearable Sensors, Global Positioning System, Global System for Mobile Communication and fields such as e-health services and location based services. Various existing systems on child and women safety are discussed with their pros and cons.
