Video slice encryption and backup method and system based on cloud platform

Abstract

The invention provides a video slice encryption and backup method and system based on a cloud platform. The method comprises the steps that A, IPCs in home monitoring subsystems collect video images, the collected video images are encoded and packaged to be a medium stream to be sent to NVR equipment which is placed in the same local area network as the IPCs for storage, and meanwhile the medium stream is encrypted and then is sent to a cloud platform server; B, the cloud platform server receives the encrypted medium stream which is sent by the IPCs and carries user information, the encrypted medium stream is sliced, NVRs used for storing the slices in other home monitoring subsystems are chosen based on physical positions and load levels, and the slices are sent to the NVRs to be stored; C, the chosen NVRs store the slices sent by the cloud platform server. According to the scheme, the purpose of mutual backup can be achieved only by part of storage space of other NVRs in the cloud platform, extra expense is not increased, and the safety of videos is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method and system for encrypting and backing up video slices based on a cloud platform. Background technique [0002] With the continuous development of IP surveillance technology and cloud services, and the continuous improvement of public security awareness, more and more consumers are familiar with and accept home video surveillance systems. These consumers hope to use the home video surveillance system to ensure the safety of family members and property. Please refer to figure 1 A home video surveillance system is shown. The home video surveillance system uses the network camera IPC to collect video, and stores the collected video on the network hard disk video recorder NVR at home through the home local area network. Users can directly watch the video stored on the NVR at home, or log in through the cloud platform in other places outside the home, and then watc...

Problems solved by technology

[0003] However, when there is an illegal intruder at home and the illegal intruder deliberately damages the video stored in the NVR or steals the NVR together, it is impossible to solve the case based on the clues provided by the surveillance video, which loses our ability to deploy the surveillance system. significance
