Video data protection system and security protection and transmission method of all involved ends

Abstract

The invention relates to the technical field of intelligent terminal video transmission, and provides an automobile data recorder video data protection method. The method comprises the following steps that: an automobile data recorder intercepts data of videos shot by a camera within a specific time interval and saves the video data in a local storage medium; the automobile data recorder automatically transmits the video data to a preset mobile terminal through a first channel; the mobile terminal uploads the video data which is received through the first channel and stored locally to a cloud end through a second channel; the mobile terminal receives upload state information representing that the video data is uploaded successfully and fed back by the cloud end through the second channel, and deletes corresponding video data stored locally; and the automobile data recorder deletes the video data which is represented in the upload state information fed back by the mobile terminal and stored in the local storage medium. Through adoption of the method, security protection and transfer of the video data are realized, and the problem that subsequent important video data cannot be stored since the video data stored in an automobile data recorder end occupies the storage capacity completely is solved.

Description

【Technical field】 [0001] The invention relates to the technical field of intelligent terminal video transmission, in particular to a video data protection method of a driving recorder, a driving recorder and a video data security protection method used therefor, and correspondingly, a video data security transmission method The method and its corresponding mobile terminal. 【Background technique】 [0002] The driving recorder can record the video data and sound of the vehicle during driving, which is equivalent to the black box of the vehicle. When the user is driving, the camera on the driving recorder is turned on, and the camera can capture the scenery or road condition information along the way, and then store the captured video information in the local storage device. Existing driving recorders have built-in acceleration sensor G-sensor, which can sense the numerical change of acceleration, and is used to forcibly record video data for a period of time before and after ...

Problems solved by technology

However, since the transmitted video data occupies a relatively large space, when the Internet access provided by the mobile communication network directly uploads the large file data to the server, the traffic of the SIM card will be exhausted, resulting in high traffic charges
