SaveMe: A Crime Deterrent Personal Safety Android App with a Bluetooth Connected Hardware Switch

A Secure social environment can be achieved if technology can be applied smartly. Nowadays smartphones have become increasingly common. This device can be used effectively if we want to live secure and smarter lives. In this paper the approach is to increase the security of our society by taking the opportunities of technologies. This paper demonstrates the simple method where there is a smartphone application along with a small device that acts as an emergency switch button. If someone falls in danger then s/he can press that button (which is connected with the phone via Bluetooth), and it sends a message about the danger to the emergency contact of the victim and notifies the nearby users who are using this app. There is a cancel button by which victims can cancel the request for help in case of misunderstanding. The designed app along with the hardware switch works as expected. The user-friendliness and low-cost of the designed app make it more convenient than existing similar systems.
