Sniffer

I have considered this situation where a person feels unsafe on a path he/she travels by walk or even while travelling in a automotive or public vehicles. In such a case the person should open my app and type their email and press the record button. For every one minute the app uses the microphone to record the talks in the surroundings and sends the location to the specified mail.
A mail usually has sender and receiver address, the sender mail is maintained by the developer one for time being i have given my mail and the receiver mail is the mail typed by user.
When a missing complaint is filed the developer can check the recording and the path taken by the person and take immediate action, instead of interrogating the people in and around the area.Even if the missing person's mail is unknown, if the mobile is found then a recording would be stored in the phone.
When a person is ragged in college the victim can show proof of being ragged by showing the recordings.
