ABBAS is an Arabic word meaning LION which symbolizes the women’s courage similar to a lion. The word Beacon refers to a light house which symbolizes the path to the person when they are in danger. ABBAS contains a mobile device and a wearable device such as watch or band. The wearable device communicates with the mobile device through the wireless module such as Bluetooth. The wearable device consists of a Bluetooth module and a switch whereas on the other side the mobile device consists of the android application. In case of any harassment, by pressing the switch in the wearable device, the information is passed to an android based Smart phone.

Through GSM in the mobile device the “help” message is sent to predefined contacts along with GPS which tracks the exact location of the person. A chat application is developed in order to send the recorded voice message to the group that was predefined in the application. The GSM, GPS, GPRS works simultaneously after the switch in the wearable device is turned on.

In addition to this some extra features are added in order to make the paper work. Firstly, a mobile wakeup is programmed in order to wake up the mobile device automatically when it is in switched off mode. Secondly, a buzzer is fixed along with the wearable device to make a loud noise when the user is in danger.

Thirdly, the system is programmed in such a way that in case of absence of cellular network and no internet connection the message is send to the programmed contact without any interrupt. In this paper, Android Studio is used to develop software by using Java programming. Thus a smart and effective device is developed in order to protect women and make them feel secured when they are alone. Keywords: Mobile phone, GPS, GSM, Android Studio, GPRS I. INTRODUCTION Women all over the world are facing much unethical physical harassment. Women experience a fear and various types of sexual violence in public places, from sexual harassment to sexual assault including rape and femicide.

It happens on streets, public transport and parks, in and around schools and workplaces, in public sanitation facilities and water and food distribution sites, or in their own neighborhoods. In India, every day more than 30 women were murdered and many are suffering austere mental and physical trauma. According to a new report from the World Health Organization (WHO), 35% of women worldwide have experienced violence. In India, according to the National Crime Records Bureau’s (NCRB) 2005 Crime Clock, there is one crime committed against women every three minutes, one molestation case every 15 minutes; one sexual harassment cases every 53 minutes, one kidnapping and abduction case every 23 minutes and one rape case every 29 minutes are reported. Shocking as these figures are, they are actually a gross underestimation of the actual situation, because crimes against women are highly under-reported. This situation has to be changed.

Major reason for the increase in rape statistics is the nonexistence of a suitable security system to ensure the safety of women. Implementation of a real time security device can solve the problem to an extent. This can be achieved by using a smart security system named ABBAS abbreviated as Android Based Beacon Emergency Alert System.

It is the security system for the purpose of women when they are in danger. ABBAS is an Arabic word meaning LION which symbolizes women’s courage equal to a lion. Beacon refers to a light set up in a high prominent position as a warning. The word Beacon is used in this paper in order to motivate the women by overcoming their problems when they are in danger. Hence the paper is titled as Beacon Alert System and since an android application is used it is named as Android Based Beacon Alert System. II. RECENTLY DEVELOPED MOBILE APPLICATION Survey shows 10 best mobile applications which ensure safety in case of emergencies listed below: A) FIGHTBACK: Fight back, the women safety application, sends SOS alerts from the phone.

Fight back uses GPS, SMS, location maps, GPRS, email and the Face book account to inform the loved ones in case in danger. B) GUARDLY: This application places phone calls to the predefined contacts along with the name, real time location, type of emergencies and enables to identify different locations. C) ON WATCH: This application is developed especially for college students. It allows the user to easily alert friends and emergency responders and police when needed with the GPS location. D) FAMILY LOCATOR: This application notifies about the near and dear ones about the trouble. It provides the useful information about the criminals in the neighborhood, trackingthe most visited locations and so on. It also keeps connected with the family members with the support of GPS.

It informs others about the exact location through messages, calls and emails with the press of a button. E) SENTINEL: It is a smart phone application used to serve as a virtual security guard for women. The users can press a button once they feel they are being stalked or harassed. It sends out instant alerts to let friends, family or police know about the trouble and save them.

F) STREET SAFE: This application has a feature called “WALK WITH ME” which gets the details of the situation and stays on line until they ensure the users gets back home safe. In case the call is cut, the safety advisor connects the user to the local police for further help and guidance. In case of emergency situations, a feature called “SILENT ALARM” enables to get local help from the real time location using the GPS and the physical description of the user. G) CIRCLE OF 6: This application intends to add 6 members to the circle which is developed for college students which lets 6 friends know when the person is facing a troublesome situation. With two taps, the app sends one out of three predetermined alert messages to six contacts of your choice including a call for help connecting home that automatically includes the real-time location.

The app also consists of pre-programmed hotline numbers and a local number that can be customized for police or 911. H) bSAFE: The bSafe app works as a guardian that sends an emergency message to the chosen contacts with a push of a single button and its slogan is “Never walk alone”. This application offers two levels of safety; a Risk mode with real time GPS which tracks the position and a Timer mode with an automatic alarm activation. It’s a user-friendly app which just needs a single tap to inform the chosen contacts. I) CAB4ME: Cab4me, as the name suggests, is a mobile cab finder app that helps get a cab anywhere at any time. It works based on the location.

The phone’s GPS shows the location on the map and one can choose the pickup destination or a nearby taxi stand based on the available stand. If in case the database has no cab company for the specific area, a local web search is performed to get a result. J) HOLLABACK: “Hollaback! You have the power to end street harassment”, is the tag line of this particular app. Here the users can take a photo of the harasser and upload it as ‘caught in the act’ and submit their story on It signals the perpetrator that his photo is shared on the website as well as warns others from doing this act.

The app encourages users to submit stories along with photographs of street harassment at every level from catcalls to strangers groping hands or even individuals exposing themselves in public roads. III. PROPOSED WORK The present and proposed work explains about an innovative idea for women security which has become mandatory now- a -days. The women wearing a watch or band when finds that someone is going to harass, she presses a switch that is located on the watch or band which then activates the microcontroller. The watch and the microcontroller are connected via the Bluetooth module. Once the Bluetooth receives the encoded information, it connects to the controller.

At the time when the microcontroller is activated, the GSM, GPS and the GPRS modules are all activated in the mobile. The GSM sends the alert message to the pre-defined contacts that is stored in the memory, while the GPS tracks the exact location of the user and sends the location along with the alert message. The extra feature that is to be added in this paper is the usage of GPRS. The new chat application is created in order to record the voice of the user when they are in danger and send to the predefined group that is saved in the chat application. This is done via GPRS simultaneously when the GSM and GPS continue with their work. Additional to this some more features are added by introducing a buzzer along with the watch which produces a loud noise whenever the switch is pressed. Secondly, a mobile wakeup is programmed which makes the mobile phone to automatically on when it is in switched off mode. Thirdly, the application is programmed in such a way that it operates when there is no cellular network and internet connection in the mobile.

Lastly, a vibration sensor is introduced which makes the security system automatically ON whenever it undergoes a fall accident. Suppose in case of false detection, a switch is pressed within 10 seconds of fall detection in order to indicate the false detection. This is done by using Android Studio. With the help of Android Studio an application is developed by using Java programming.

Thus the proposed smart alert device helps the user in the efficient and more effective way when they are in danger.
