Abstract
Most of the crimes that happen these days don't reach the police either because nobody reports them or there is no real time proof. The citizens don't have the real-time images, videos related to the crime, and hence, it goes unreported. This chapter presents a real-time video call-based crime reporting system, where the crime victim or an eye witness can start an end-to-end encrypted video call with the police present in the nearest police station. A data science approach is used to find the nearest police station. Once the police officer picks up the call, he will get the location of the crime and nearest route to reach the crime spot. Police can even catch the criminals or handle the crime while it is happening. After the video call ends, a recording of that call will also be available to the police.
TopIntroduction
There is a huge surge in the number of crimes which are taking place in India. Each new day, a different type of crime emerges. The main job of the police force is the identification and recognition of the criminals (Rasanayagam et al., 2018). But the cops face difficulties in finding the location of crime when it is happening and the correct evidences related to the crime. New advancements in technology are proving helpful to police to prevent the crime incidents and to enhance the overall performance of the police (Byrne & Marx, 2011). Most people don’t find it convenient to go to the police station to report the crime. In such cases, handheld devices like mobile phones and tablets can prove to be a helpful tool in the effective and online reporting of these varied crime incidents (Mcclees, 2019; Sekhri, 2020).
