Abstract: Women safety has been a big concern and it has been the most important duty of every person. There is no chance of the welfare of the world unless the condition of the women is improved. Since the ancient time, women are given most respected place in the society but every day and every minute some women of all walks of life (women, girls and babies) are getting harassed, molested, assaulted and violated at various places all over the world. It is estimated that 35% of the women have experienced physical and/or sexual violence at some point in their lives. This paper includes various ideologies and methodologies of numerous authors who have reviewed multiple applications and devices using present technologies and processors and they have also upgraded these with certain requirements in order to decrease violence against women. Also a small measure of improvement proposed in this paper, adds to the better performance of these devices and lead to better women safety. 

INTRODUCTION

This paper involves few precautionary devices and applications in order to prevent or avoid the problems faced by women. It is not only about prevention, but it also helps the women deal with the problems faced in the past and achieve fair justification and morality in the society. The safety and security of a woman can never be at rest, no matter what new device is on the market or no matter how nice a new application is made, there always can be something added to it. There cannot be a cop always guarding a woman, but there can be secret safety measures with them which can be easily used at the time of threat and let the nearby people know that there is something bad happening and their support is need. By keeping all these things in mind many safety devices have been made and few of them are discussed in this paper. Literature The paper [1] proposes a safety device and application called FEMME using ARM controller. It is a security device which is specifically designed for women. The device and be purchased or the application can be installed in smart phones and can be accessed in emergencies. FEMME provides quickest and easiest way to contact for help, when a person is in distress. The application is activated by pressing the volume key and the power button together. When the application is being used, first it displays 4 main icons, audio recorder, SOS message, video recorder, hidden camera detector. Depending on the option pressed now, it either sends message and recording to the preset contacts or detects the hidden cameras. Whereas the device is activated by pressing the button on it, the device is linked with smart phone and it provides 2 buttons, one being the emergency button and the other to activate hidden camera detection. If the emergency button is clicked once (Single Click) the GPS location is tracked and is sent to preset contacts once in every 2 minutes with updated location. If it is clicked twice (Double Click) audio recorder is activated and is sent to preset contacts with an emergency help message. If it is pressed for long (Long Press) it automatically calls the preset contact. By using ARM controller the device works without internet connectivity and is an all in one system, the controller uses less power and gives more efficiency. The paper [2] proposes a device which is portable and it also resembles a belt. This device was developed after seeing few applications and devices such as VithUapp which was initiated by a popular TV series Gumrah aired on channel [V], SHE(Society Harnessing Equipment) which generates current to help victim escape, and ILA security founder designed an alarm that can shock and disorient attackers. This device includes Arduino board, GSM shield, GPS module, screaming alarm and pressure sensors. The arduino board consists of everything which requires to start up the microcontroller, it can be started by connecting it to a computer or powered with an adapter or even a battery. The GSM shield provides data, voice, SMS and fax in a small form factor with low power consumption. It is a very powerful single chip processor with high efficiency and speech quality and it supports low cost handsets and is also compatible with almost all telephone services. The GPS module provides current date and time, corresponding longitude and latitude, and also sends speed and travel direction if the victim is travelling. It helps to track the victim and makes it easier to access their location and find them. The screaming alarm offers single chip voice recording and playback capability for 40 to 60 seconds. It is ideally used in portable voice recorders. The pressure sensor generates a signal when pressure is imposed on it, it is usually used to capture the change in pressure. In this device a threshold limit for pressure sensor is set, and when the threshold crosses the device gets activated and tracks the location of the victim using GPS module and sends the location to preset contacts and other emergency services such as police control room for every 2 minutes with updated location. The screaming alarm will be activated and it sends sirens to let people know that there is trouble nearby and help is needed The paper [3] proposed a system consists of wearable safety device having an emergency button for sending notification and camera for capturing assaulter image, thus location of the victim is traced with help of GPS and image gets captured. Emergency message with image link will be sent to all

CONCLUSION

All the applications and devices are built by using new technologies and processors, where in it might become difficult to operate for women in rural areas and uneducated people, also makes it difficult for them to use smart phones and their updated features. And if the phone is running out of battery, the application present in the phone cannot be used. Therefore we propose here, a novel idea to make the device easily operated by rural women folk. The device can be designed to have 2 or 3 colored buttons on it, when the threat arrives a specific button can be pressed, where in the buttons will be programmed with required and necessary functions. As we see the proposed device has 4 colored buttons on it i.e., red, blue, green and yellow. When the red button is pressed it triggers the alarm sensor, the blue button sends an emergency message to the preset contacts, the green button records the audio and finally the yellow button helps detect hidden cameras. The smart phone problem cannot be easily solved because of its too many advantages, no other device can provide those many applications which almost support all the features required in order to use an application or even link a device and operate it. The battery backups of present smart phones are pretty good, but still a person always needs to makes sure that the battery will last until the end of the day. There are many more portable devices just in order to charge the phones (portable chargers), they can be used to charge the phones before the battery dies. People who are not comfortable in using applications which are installed in smart phones can always opt for devices. The devices can be made in different forms and sizes using specific components. It can be a belt, band or even a cosmetic shaped item. Even defense items can be introduced in different forms such as lipstick stun gun which gives shock etc. By using these different forms of devices attacker can be tackled easily because he might not be aware and has no knowledge about the presence of such devices.
