Abstract

The invention provides an encryption method and device, and a video monitoring system. The method comprises the steps that a video sending end encrypts a video by use of a password corresponding to an encryption level according to the encryption level of the video; and a video receiving end obtains the password corresponding to own authority according to own authority, thereby decrypting the video. According to the method, the device and the system, multi-level authorities are set and different passwords are set for different authorities, thereby decrypting the video; and the video transmission security can be improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to an encryption method, device and video monitoring system. Background technique [0002] In order to improve the security of the video surveillance system, at present, passwords are generally used to encrypt the video, that is, the video is encrypted by the video sending end, and then the video is decrypted by the video receiving end having the receiving authority (with the password). This encryption method is relatively simple and easy to implement, but the risk of the password being stolen is very high, and the purpose of protecting the video cannot be achieved. Contents of the invention [0003] The object of the present invention is to provide an encryption method, device and video monitoring system, which are used to set different passwords according to different permissions. [0004] For realizing the above-mentioned purpose of the invention, the present inventio...
