(3) certificate server entrusts the effectiveness of unified entry system checking user conversation, if detecting when ID or TOKEN are invalid, directly in response to being not logged in；When user conversation is expired, respond as invalid session；When user conversation is effective, unified entry system takes out the Permission Levels of active user from database server, returns to certificate server as response results。
(4) certificate server is after obtaining the Permission Levels of active user, obtains the Permission Levels information of accessed resource according to resource ID to resource management server, when user right grade is not enough to corresponding resource is conducted interviews, responds as insufficient permission。
(5) certificate server judges whether active user ID is in broadcast state, if active user ID exists the session play, is then provided the video server break of video transmitting procedure of service by certificate server notice。
(6) video server sets up the RTMP interface channel with client, and the dynamic key of stochastic generation 16 byte length is sent to client as this session key, then notify the RTMP successful connection of certificate server current sessions, certificate server update the broadcast state of current sessions。
(7) client receives session key, is stored in this locality, and sends key response message to video server。
(8), after video server receives the key response of client, carry out video data transmission, according to current session key video stream data carried out real-time encrypted after transmission。
(9) client receiving stream media data, are decrypted into normal play after expressly。
(10) when the video data transmission of this session is complete, video server notice certificate server updates the broadcast state of user。
The present invention has done following extension on the basis of standard RTMP protocol realization:
(1) extending the RTMP connection request of client, client needs to provide in request data: ID, user conversation ID, TOKEN and resource ID information, adds the process logic of key reception response and video data real time decrypting simultaneously。
(2) the process logic of video server is changed, video server is after receiving the video request that client sends, Video service is not directly provided, but from request, first extract ID, user conversation ID, TOKEN and resource ID information, transfer to whether certificate server checking active user possesses enough access rights。After being verified, just can set up RTMP with client and be connected and provide follow-up Video service, otherwise it is assumed that be invalid connection request, refusal connection。
(3) video server is increased generation dynamic key and the function to the real-time encrypted transmission of video data newly。
(4) newly-increased certificate server, the service interface to user identity and Authority Verification is provided to video server, certificate server is according to ID and resource ID information, it is determined that whether the request of active user is legal, and Authority Verification result is returned to video server。
(5) newly-increased resource management server, is used for administering and maintaining all of streaming media resource, externally provides the interface of Query Resource Information。As it is shown on figure 3, the operations such as video resource can be uploaded on backstage, deletes by management personnel, authority change。Resource management server can regularly detect the change of local repository, once detect that local resource increases or reduces, then can notify that each video server carries out the renewal of resources bank immediately, thus the resource consistency ensured on each video server。
The present invention has the feature that
1, dynamic key encrypted video stream。Video server generates different dynamic key for each session connection, and data are encrypted transmission, and client real time decrypting is also play, and neither affects the real-time of video playback, adds again the difficulty that algorithm guesses that solution and ciphertext crack。
2, prevent video from being downloaded and illegally propagate。The present invention prevents video resource by illegal download and illegal propagation by the approach that video data is encrypted, video content after encryption cannot be play, the personnel that crack are when lacking decipherment algorithm and decruption key, it is difficult to obtain the content of video, fundamentally prevent video content from being leaked。
3, prevent No. one multiplex。The certificate server connection feedback information by video server, the broadcast state of each ID of real time record, when same account number repeatedly logs in and asks Video service, the video request only sent for the last time is considered as effective, and before same account, ongoing video display process can be forced to interrupt。So can prevent account number many places from logging in, and ask the situation of Video service to occur simultaneously, it is possible to limit an account number on same equipment, carry out the page quantity of video playback simultaneously。
