Description
Technical field
It is specifically a kind of the present invention relates to technical fields such as video security protection, information technology, encryption technology, cryptographic key protections
Video data protects system and processing method.
Background technology
In recent years, under the influence of the trend such as Internet era, big data, Internet of Things, video monitoring is from police, industrial
Change application gradually toward the direction of each field and civil nature to develop.In this development, the most distinct issues run into are
Video information leakage problem, fear that individual privacy leakage has turned into main misgivings of the user without using video security protection equipment.
Mainly there are two methods to prevent video data by bootlegging broadcasting at present：
1. building video private network, isolated in network level；, can not be in civilian city but the construction cost of this method is too high
Promote field.
2. using privately owned transmission of video agreement, present main flow producer is all to use the program.Shortcoming：Formulate transmission of video association
The people of view, completely it can be seen that the video data of client；Privately owned transmission of video agreement can be cracked, all video counts after cracking
According to all may be by bootlegging broadcasting；It is big with other video platforms docking difficulty, limit very much user and use video data.
The content of the invention
For defect present in prior art, it is an object of the invention to provide a kind of video data protection system and place
Reason method.Technical problem to be solved is：Video security protection equipment owner is allowed really to turn into the owner of video data, video
How data deposit, how to use, who can see all is had the final say by video security protection equipment owner.
To achieve the above objectives, the present invention adopts the technical scheme that：
A kind of video data protects system, including the storage of video generation module, video-encryption module, cipher key module, video
Module, purview certification module and video use module；
