SYSTEM AND METHOD FOR DETECTING IMAGE MODULATION OF AUTOMOBILE BLACKBOX

摘要

The present invention relates to a system and a method to detect image modulation of an automobile black box. The system comprises: an automobile black box; a network; and a server. The automobile black box comprises: a camera to shoot an image; a sensor unit to detect an accident of the automobile; a control unit to perform authentication to the server and to secure integrity by transmitting the image of the accident and a hash value when an event occurs; a timer to provide time information to the control unit; and a communications unit to transmit and receive data inputted and outputted through the network. The server registers and controls the automobile black box, and saves the original image of the accident and the hash value transmitted from the network. According to the present invention, a user can check if an image is modulated to play a big role in solving the incident, clearly estimate the wrongdoer and the victim, and detect an act of modulation or deletion and secure the original image. The present invention is able to simplify and automate the image modulation verification process, which requires a lot of cost and time, and to improve economic feasibility and convenience.
