Abstract

The embodiments of the invention provide a CPK-based video monitoring method and system, a camera, a server and a client, which belong to the field of video monitoring technology and solve the problemthat the video data is completely exposed to an insecure environment. The method comprises: receiving a camera startup message sent by the server, and verifying the authenticity of the camera startupmessage, the camera startup message comprising a authenticity proof of the server, a authenticity proof of the camera and an authenticity proof of a startup instruction; when the camera startup message is verified to be true, acquiring video data; generating video transmission data according to a private key and a random key of the camera and the video data, and sending the video transmission data to the server, the video transmission data comprising the authenticity proof of the camera, an authenticity proof of a key frame at each positive second in the video data, a frame integrity code ofthe key frame, an integrity code of the video data, and the encrypted video data. The method and the system are applicable to a process of processing video monitoring data.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a CPK-based video monitoring method, system, camera, server and client. Background technique [0002] The development process of video surveillance system is from the first generation of analog video surveillance system, to the second generation of digital video surveillance system based on "PC+multimedia card", and then to the third generation of completely IP-based network video surveillance system (IP VideoSurveillance, IPVS). The current mainstream system is IPVS. [0003] It can be seen from the composition of IPVS that the front-end acquisition system and the back-end processing system are connected through the IP network. Among them, the back-end system is arranged in the central computer room, and the system protection is relatively complete, so it is relatively safe. The cameras in the front-end acquisition system generally have physical protection methods suc...
