Abstract
The invention provides a method for preventing video stream data from being illegally accessed. The method comprises the following steps: encrypting the video stream data by use of a secret key through a symmetric encryption algorithm; after the secret key is encrypted by use of a USB, sending the secret key together with the video stream data to a client; the client decrypting the secret key after encryption by use of a corresponding USB to obtain the secret key; and restoring the video stream data through the secret key. By use of such a technical scheme, the method for preventing the video stream data from being illegally accessed, provided by the invention, prevents the video stream data from being illegally accessed and only enables authorized users to access videos.
Description
Technical field
The invention belongs to Video security transmission technique field, particularly a kind of video stream data that prevents is by the method for unauthorized access.
Background technology
Video fail safe in transmitting procedure is not high, after video stream data is revealed, by the utilization of lawless person, can cause serious consequence.
Summary of the invention
The object of the present invention is to provide a kind of video stream data that prevents by the method for unauthorized access, by the method, prevent video stream data by unauthorized access, authorized user just can have access to video stream data.
The object of the invention is by such technical scheme realize, comprising:
Adopt symmetric encipherment algorithm, use double secret key video stream data to be encrypted:
After being used by key USB to encrypt, be sent to client with video stream data;
Client uses corresponding USB to be decrypted the key after encryption, obtains key;
By key recovery video stream data.
Owing to have employed technique scheme, the video stream data that prevents provided by the invention, by the method for unauthorized access, prevents video stream data by unauthorized access, just can have access to video through the user authorized.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
The present invention includes:
Adopt symmetric encipherment algorithm, use double secret key video stream data to be encrypted:
After being used by key USB to encrypt, be sent to client with video stream data;
Client uses corresponding USB to be decrypted the key after encryption, obtains key;
By key recovery video stream data.
Owing to have employed technique scheme, the video stream data that prevents provided by the invention, by the method for unauthorized access, prevents video stream data by unauthorized access, just can have access to video through the user authorized.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing specification of the present invention and accompanying drawing content to do, is directly or indirectly used in the technical field that other are relevant, all in like manner within scope of patent protection of the present invention.
