This paper surveys about the security system for women and children which allows immediate responses in any harassment in public places, societies etc. Women all over the world are facing unethical physical harassment and Children cannot be left unattended at a social event or outside the home. Our project solves both the problems. A portable device which will have a pressure switch. As soon as an assailant is about to attack the women/child or when they senses any insecurity from a stranger, he/she can then put pressure on the device by squeezing or compressing it. Instantly the pressure sensor senses this pressure and a conventional SMS, with the victim’s location will be sent to their parents/guardians cell phone numbers stored in the device while purchasing it, followed by a call. If the call is unanswered for a prolonged time, a call will be redirected to the police and the same message will be sent. The main feature of our system is less response time will be required for helping the victim.
The misbehavior against children and women are increasing rapidly. They are under the threat of easily being kidnapped. In modern India, women continue to face social challenges and are often victims of abuse, violent crimes and harassment  . At the same time children’s security has always been a priority problem whose solution must constantly be improved. Since the prediction of such incident is not possible hence to minimize the possibility of physical violence (robbery, sexual assault etc.) by keeping all the help tools ready to safely escape from violent situation. This reduces risk and brings assistance when needed  . This project focuses on a security system that is designed solely to serve the purpose of providing security and safety to women and children so that they never feel helpless while facing such social challenges.. II.EXISTING SYSTEMSA.Smart Girls Security System This system designed for providing security to women in the society so that they never face physical harassment. The system is designed by GSM shield (SIM 900A), alarm (APR 9600), GPS, ATMega328 Board, power supply unit and pressure sensors . B.Mobile based Women Safety Application Many android based app has been developed for women security in the societies for providing emergency help. Some of them are VithU app, Fight back app, Stun gun app etc . C.RFID –GSM imparted school children security system The main aim of this system to provide safety for school children. In this system sensors like obstacle and range detection are placed on the front surface of the bus so that collision should be avoided on road. Each student is having unique id. Two counters are used in this system, one at entry point and another at exit point. Wireless communication technology is used to inform the parents and staff regarding the status of bus . D.Society Harnessing It is a electronic circuit which is designed by three engineers from Chennai. This circuit is having a power of generating 3800kv current for help the victim to escape. It can also send different types of 82 shocks in case of multiple attack. The user is not affected because fabric used is bilayer. It can also send emergency messages to relatives and parents of victim .
This paper survey about the existing safety application for women and children and comes out with idea for making safe environment for women and children in the society, and allows them to go anywhere fear free. and it help reducing the crime rate against the women and children. Our Future Scope includes the real time implementation of the proposed system in tiny size with the additional components heartbeat sensor for monitoring the heartbeat of women and children in every second by measuring variation in blood volume in tissues and analysis of various parameters related to heart beat for individual women and children.
