Data managent method for preventing alteration of the data in real-time video data storage system

摘要

The present invention relates to a data management method capable of preventing forgery of image data extracted and stored in real time. The data management method includes a process of receiving an image, a process of analyzing the input image to detect whether a preset event has occurred, and when an event occurrence is detected, an event image file as an event image related to an event from among the received images It includes a process of creating a video file, storing the created event image file in one or more write once read many (WORM) storages, and generating image metadata for the event image file. According to the present invention, by simultaneously utilizing block chain technology and WORM storage technology, it is possible to double prevent forgery and falsification of image data extracted and stored in real time.
