Abstract- ABBAS abbreviated as Android Based
Beacon Alert System is a security system to protect women
themselves when they are in danger. 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.

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, tracking

the 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 ihollaback.org. 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.

CONCLUSION

In this present paper, titled “ANDROID BASED
BEACON ALERT SYSTEM” by using traditional
instruments is very difficult and time consuming. Usage of RF
will gives less accuracy. Thus presently in this paper, it has
been used with android app and Bluetooth which gives high
accuracy and by using GPS it is possible to detect the human
location accurately along with the development of chat
application. This paper surveys about the existing applications
for women security and comes out with an innovative idea for
security and protection for the women. More research is
possible with introducing IoT technology where people and
objects form a network.
