3. Introduction
In the light of recent outrage in Delhi which shook
the nation and woke us to the safety issues for
women’s, people are finding up in different ways to
defend. Here we introduce a device which ensures
the protection of women. This helps to identify
protect and call on resources to help the one out of
dangerous situations. Anytime you senses danger,
all you had to do, is hold on the button of the
device.
