Security camera media data encryption technology

Abstract

The invention relates to the technical field of security and protection monitoring, in particular to a security and protection camera media data encryption technology which comprises the following steps: electrifying a camera, reading account information of a user from a configuration file, and confirming that video data or live broadcast is started; the method comprises the following steps: generating an AEC encryption key KEY1 by using user account information as a key seed, encrypting the first 100 bytes of an audio and video frame by using a key Key1, writing encrypted audio and video data into a video file or sending out in a live broadcast manner, adding the first six bytes of the encrypted data with the account information of a user, generating a KEYNEW of a subsequent encryption key, updating a key buffer area, and sending the encrypted audio and video data to a video recording server; and continuously updating and encrypting the data through continuously repeated steps, and finally ending video recording or live broadcasting and clearing data in a secret key buffer area after encryption is completed. The method is suitable for security and protection camera equipment with a video recording function, video recording data can be encrypted in real time, user data leakage can be safely and effectively prevented, and therefore leakage and diffusion of user privacy data can be thoroughly eradicated.

Description

technical field [0001] The invention relates to a media data encryption technology, in particular to a security camera media data encryption technology, and belongs to the technical field of security monitoring. Background technique [0002] As an important imaging tool, the camera has been widely used in civil and military fields such as mobile terminals, automobiles, drones, robots, smart homes, video security, AR, etc.; cameras generally include lenses, photosensitive chips It is encapsulated and fixed by the encapsulation structure and set corresponding to the lens, so as to receive the light from the object side from the lens to generate the image signal; [0003] Among them, the security camera is one of many cameras. The security camera refers to the camera used in security protection. Its main features are high sensitivity, strong light resistance, small distortion, small size, long life, shock resistance, and remote control. monitoring; thus being widely used; [...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a security camera media data encryption technology, which is suitable for security camera equipment with a video recording function, can solve the security problem of the camera media data, and can encrypt the video data in real time, even if the video file itself leaks, there is no user Participate by yourself, and can't play back and watch through the player software, so as to completely prevent the leakage and spread of user privacy data
