Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Embodiment 1：A kind of bid video conference and monitoring system, the bid video conference and monitoring system are used in
Open bid in subsystem, long-range strange land assessment of bids subsystem, opening of bid subsystem and long-range strange land assessment of bids subsystem are in whole bid system
It is only wherein several subsystems in system.
Apply to before bid video conference and monitoring system, bidder carries out bid online report by bid subsystem
Name, tenderer such as has intention to throw after information promulgating platform or bid subsystem, bid subsystem see the call for tender
Mark, first has to first turn into bid subsystem register user, arrives first bid and do the archives that build one's credit, while apply for CA digital certificates,
Bid subsystem is logged in CA digital certificates or bid subsystem carries out bid registration.
As depicted in figs. 1 and 2, bid supervision subsystem includes being deployed to screen meeting in LAN and separate
Module and monitoring module.Screen meeting module video front monitoring front-end collecting device, applies to assessment of bids room and askes in mark room, in the assessment of bids
Opened before starting by being responsible for people specially, marking the audio of room, screen to assessment of bids room and inquiry in real time during the assessment of bids is carried out
Communication and record.
Monitoring module video monitoring front-end collecting device, carries out 24 small to opening of bid room, assessment of bids room and inquiry mark room overall condition
When record free of discontinuities.
The video monitoring front-end collecting device in screen meeting module and monitoring module is applied to include video camera, video
Encoder and sound collector, the respective information needed of two module independent acquisitions.Two video monitoring front-end collecting devices are accessed
Interchanger is transferred on WEB server or database server, and is exchanged by WEB server or database server by storing
Machine is preserved to storage carrier.
When assessment of bids room and the personnel ask in mark room need to open screen meeting module, screen meeting module is accessed by exchanger
Video conferencing system central control equipment and recording service device are stored.
During assessment of bids room and inquiry mark room access video conferencing system central control equipment, identity information core need to be passed through
It is real.Therefore, information authentication module is also included in screen meeting module, information authentication module includes the identity with digital certificate and tested
Demonstrate,prove server and positioned at assessment of bids room or ask the indoor identity of mark, identity need to be recorded in opening of bid subsystem, as
It can be obtained during bid subsystem register user.Binding is stored into Authentication server in advance for the identity, can be several
Word number information, image information, audio-frequency information, the one of which of video information or any a variety of combination, digital number information
Number, the photo that image information obtains for registration are demonstrate,proved for province, audio is the sound in staff, and video is then with work
The video of personnel face.
, it is necessary to corresponding with the identity in Authentication server before assessment of bids room and the room access of inquiry mark.
Specifically, video conferencing system central control equipment is received after Authentication server response message, carry out such as
Lower processing：
S1, the first random number and the second random number are read from the local storage of video conferencing system central control equipment, point
It is not compared with the first random number and the second random number in authentication response information accordingly, judges whether random number is consistent；
S2, the reading video conferencing system central control equipment body from the local storage of video conferencing system central control equipment
Part mark and video monitoring front-end identity, are respectively correspondingly controlled with the video conferencing system center in authentication response information
Equipment identities are identified and video monitoring front-end identity is compared, and judge whether identity is consistent, the identity must
It must be wherein any two kinds of combination of digital number information, image information, audio-frequency information, video information；
If the judged result of above-mentioned S1~S2 any one is no, access failure；If above-mentioned S1~S2 judged result
It is all to be, then perform S3~S5；
S3, the digital certificate for obtaining Authentication server, according to authentication response information, the first random number, the second random number, are regarded
The identity of frequency front monitoring front-end, the identity of video conferencing system central control equipment, authentication key ciphertext and identity are tested
Demonstrate,prove key information and build access response message, using video conferencing system central control equipment certificate and private key to access response message
After being signed, video monitoring front-end is sent to；
S4, video monitoring front-end receive access response message, are verified using video conferencing system central control equipment CertPubKey
In the validity of the signature of the access response message, use certificate server certificate public key verifications access response message
The validity of the signature of authentication response information, in signature verification by rear, judge authentication result in access response message,
Whether random number and identity are effective, if any one is invalid, access failure；If each single item is all effective, video is used
Authentication key ciphertext in front monitoring front-end certificate and private key decryption access response message, and obtain unique data key；Simultaneously
Authentication key is tied in authentication key information；Wherein, authentication key information is except including authentication
Key, the also information such as index comprising authentication key；
S5, calculate data key and Message Authentication Code according to authentication key, and build access confirmation message, be sent to and regard
Frequency conference system central control equipment；Access confirmation message includes the first random number, the second random number, video monitoring front-end identity
Mark, the identity of video conferencing system central control equipment, authentication key and Message Authentication Code.
As depicted in figs. 1 and 2, monitoring module is accessed by exchanger and stored up on DVR and monitoring management server
Deposit.
DVR has built-in hard disk, the video that monitoring management server gathers video monitoring front-end collecting device
Information generation video file is simultaneously stored to built-in hard disk, and video file has a unique file identification, and unique file identification can be with
It it is filename or period, monitoring management server reads the video file in built-in hard disk and is uploaded to cloud platform by network
On.
During upload, monitoring management server detects the video recording for whether having identical filename in cloud platform first
File, for judging that this is transmitted as uploading or resuming for the first time.When being not detected by same file mark, reading has unique text
The video file of part mark is uploaded, and the record constantly mark upload progress in upload procedure；When detecting same file
During mark, according to the upload progress of last time mark, file remainder is read by inlet flow and continues to upload；Need
Bright, monitoring management server reads during video file is uploaded to cloud platform and generates another lock with administration authority
Determine file, the administration authority limitation video file of the lock file can not be changed and deleted, it is ensured that the file of upload is not damaged by
Or change, lock file is deleted after upload, video file recovers original authority.
Monitoring management server detection video file is uploaded to the video file deleted after cloud platform in built-in hard disk, makes interior
Put and vacant state is remained in hard disk.
The above embodiments are only explanation of the invention, and it is not limitation of the present invention, people in the art
Member can make the modification without creative contribution to the present embodiment as needed after this specification is read, but as long as at this
All protected in the right of invention by Patent Law.
