Distributed Crime Reporting System Arjun Bhadra Rishabh Shah Soumya Mishra
Motivation and Goals The main idea is to develop a distributed crime alert application to connect witnesses/victims with (nearest)police station through a smartphone application broadcast crime alerts to all users residing near the crime location in real time(similar to AMBER alerts) receive feedback from witnesses on crime events occurring in their vicinity detect spatial-temporal events and report as an aggregated event to the police track and analyze historical crime data easily
Infrastructure Android application (to report crimes and receive alerts) MLab (mongodb hosting service to store crime & user information) Google Cloud Messaging (to broadcast alerts) Middleware in Java and Python provides web services for dispatching crime events, gathering information from witnesses and providing aggregated reports on crime data
Middleware The web services will be hosted on an Amazon EC2 instance. The Android application connects to this instance and populates user and crime information through a RESTful model of communication. Middleware fetches relevant information from user and police, and populates into our MongoDB residing in mLAB (which is a MongoDB Hosting service) Google Cloud Messaging fetches all the users near the crime spot from our DB and broadcasts crime alerts to them.
Working features Android application: User can report a crime event as a witness or victim (SOS). Users can receive crime alerts and provide any additional information. Middleware: Store relevant information in MongoDB intelligently (spatial-temporal events). Broadcast alerts to users residing around the crime location Multithreaded implementation to support high volume of concurrent requests
