Evidence Collecting System From Car Black Boxes

Abstract

This demonstration shows how to effectively collect and manage information obtained from car black boxes in vehicular networks. The car black box is a vehicle-based CCTV which records video images, sound, position, speed, and time. These data can be used for accurate car accident investigation and some public crimes prevention. However, there are important issues such as user privacy and a data management for a vehicle-based CCTV records. The proposed evidence collection system can reduce driver privacy concerns and communication and management overheads. Our contribution is that we propose a feasible and useful scenario for public safety. By using above technique we are going to use various sensors and video devices in order to capture the various conditions like accidents or crimes, etc. Camera gets turns on only when MEMS sensor gets activated and starts recording video and stores recorded video in pen drive connected to micro controller as well as it automatically sends alert message to control room through GSM/GPRS modem. The captured data can be transmitted and stored in pen drive through USB port from vehicle to Monitoring centre data base. Depends on user requirement (owner) the data can be accessed by security and police departments to analyze the received data. This is very confidential, without permission no one can access the data. The system uses a compact circuitry built around ARM microcontroller; Programs are developed in Embedded C. Flash magic is used for loading programs into Microcontroller.
