Introduction:
Peril alert is based on an android application. The central concept of the application is to provide safety to the user in hazardous conditions. The word `PERIL' defi nes a condition in which a person is stuck! And needs HELP!! It helps the user to reach his friends or family by using certain type of short messaging services. With no e ffort the user can simply convey the `DANGER SITUATION'to his nearest rescue person. Based on Android Open Source Operating System. Mainly used in Smartphones providing continent functionality, making it a leading Operating System.It uses Android's Peer-to-Peer (P2P) text and data communication protocols, specially instant messaging and SMS.
Problem Definition:
To develop a system that uses the short messaging service to instantly send our location which can be determined using the global positioning service provided in the smartphones.The application can help us to rescue from a hazardous situation by sending the location to our friends.
Use the Google maps to trace the location and in a click the location is sent through the SMS.
Instead of calling someone and asking for help,this is more preferable and can get help in a short time.
In case of recording an evidence, the recording function can also be used.
Storing a number and the message with the latitude and longitude of our present location can be send by just clicking the "save me" button.
Proposed System:
The Peril Alerts is an application which uses Global Positioning Service (GPS) and short
messaging service (SMS) using peer-to-peer communication to trace the current position of
user and send it through SMS in one touch which allows user to get help as soon as possible.It
also gives the feature of voice recording for evidence purpose.Consider you are in a situation
where your life is in danger and you want someone to come and save your life and be your
saviour, when you are in such hazardous situation it may not be possible for you to simply
call or text your saviour and let him know about your situation and where are you at the
movement.so this application allows you to save the number of the saviour so no need to
enter it at the time of emergency and you can send him message on one touch

| Basic working |
figure above shows how actually the application will communicate with the satellite and send the location through the sms. We are also planning to add more features to our application.
Working of the application:
This android application mainly consist of following modules:
1.Contact Operation:
After the user has installed the application the user has to first add the contacts (i.e phone numbers) from the phone contact list to the application which can reach out for help.
Add the contacts by : Menu-> Select Contact(s) -> Check the contact names you want to send message.
At a later instance the user can also delete the contacts from the application. On a note , the user does not need to add the contacts every time before using this application as it stores user's last entry.
2.Global Positioning System (GPS) Operation:
When using the application if the user has checked the "Include Location in Reply" check box then the application always fetches the user's current location using the Global Positioning System (which is mostly available in all smartphones) prior to sending the message.
3.Sending SMS:
When the user feels that he/she has ran into a place they have no clue about or any hazardous event/ condition is about to take place the user can just click the "SAVE ME" button and the application sends the user's current location along with the pre-specified message (as shown in screenshot) to all the contacts as a SMS using the normal data charges.
4.Recording:
In case the user might want to record specific sounds coming from the vicinity or need to record a evidence, they can just use the toggle button "Start Recording" to begin and when they are done "Stop Recording" would save the audio file in the external storage of the phone.
