Description
Technical field
The invention belongs to information security field, and in particular to one kind is based on high-definition media interface and dynamic two-dimension code video
Audio frequency and video and data unidirectional transmission system under Network Isolation state are realized in synthesis, are more particularly to one kind in intranet and extranet isolated instances
Under data safe transmission system.
Background technology
With the continuous ripe and development of Internet of Things+concept product, various applications or data system federation are with some form
Access network and finally and internet（Public network）Interconnection, and in many cases, need to extract the number on internal network server again
Sent in real time according to outside.But information security form is increasingly serious, once for there is the system access network of security requirements, even if
Fire wall and the class technology of intrusion detection one have been used, the risk that system invasion and information data are revealed will have also been faced, in order to ensure
Internal network security, protects according to network safety grade and requires, internal-external network will realize complete physical isolation.Prior art master
Want present situation as follows：
1st, mainly have the technologies such as fire wall, intrusion detection, VPN, gateway on network security technology at present, really meet physics every
From desired mainly physics isolation net gap technology；
2nd, physical gateway technology is just progressively promoted at present, but there is buying and use cost height, technical configuration complexity, and configuration is once
The problems such as not enough strictly exposing and damage built-in system.
In order to overcome this defect, there are many solutions isolated for inside and outside network physical, such as Chinese patent Shen at present
Please numbers 2015104591787, title " method, terminal and system that resource data is obtained from outer net " propose client in terminal
End is logged in after the console of intranet server, is obtained and is accessed data, and resource is sent to outer net Resource Server according to access data
Request；The resource data that outer net Resource Server is returned according to resource request is received, resource data is transmitted to console, for
Console is handed down to interior network termination.
It is not unique, but has its counterpart, and " a kind of physical isolation based on Quick Response Code is passed for Chinese Patent Application No. CN105049425A, title
Transmission method " needs the initial data sent to carry out automatic Partitioning processing in first network terminal-pair, obtains block data；To each point
Block number evidence is encrypted and is respectively converted into corresponding two-dimension code image, and obtains combined two-dimension code picture by numeric order；The
Two network terminals are scanned by two-dimensional code scanning device or high-speed camera to combined two-dimension code picture, are being decrypted simultaneously
Disassemble analysis merging and be divided into corresponding each two-dimension code image, obtain the initial data after complete merge and stored.
Comparatively speaking, number of patent application 201310116961.4, title " data transmission system based on image recognition " are carried
The technical scheme of confession is more direct.It is that the data of acquisition are subjected to Image Coding in interior net image transmission server, generates image,
And send images to display and show；The image that display is shown is gathered by external camera again, and will be collected
Image be sent to outer net image transmission server；Outer net image transmission server is used to obtain image and be decoded, and obtains
Data, and give outer net system by the data transfer of acquisition.
By introduction as can be seen that several solutions are improved both for intranet and extranet interaction above, though there is it
Positive effect, but still have inapplicable part, the first solution is by console come transfer, and console needs to connect inside and outside
Net, again without really realizing pure physical isolation.Second of solution does not possess, it is necessary to which external equipment, manual scanning is read
Feasibility.And though the third solution can realize intranet and extranet information one-way interaction automatically, gathered and schemed by external camera
Picture, accuracy rate discrimination is not high, and easily affected by environment, stability is poor.
Many computers all support high-definition media interface output function at present, carry out man-machine interface operation for user, use
It is highly stable, conveniently.
Analyzed more than, the present inventor proposes a kind of real with dynamic two-dimension code Video Composition based on high-definition media interface
Thus audio frequency and video and data unidirectional transmission system under existing network network isolation, this case produce.
The content of the invention
Network is realized based on high-definition media interface and dynamic two-dimension code Video Composition it is an object of the invention to provide one kind
Audio frequency and video and data unidirectional transmission system under isolation so that in the state of Network Isolation, realize that external network system is pacified
Full by high-definition media interface, internally network uni-directional transmits audio/video flow and two-dimensional code data, internal network analysis in real time
Server gathers audio/video flow in real time, and extracts two-dimension code image, two-dimension code image relevant information is decoded, to relevant information
Carry out preservation management, finally can by voice message feedback information whether successfully decoded.Vice versa.
In order to reach above-mentioned purpose, solution of the invention is as follows:
Realize that audio frequency and video and data are unidirectional under Network Isolation state based on high-definition media interface and dynamic two-dimension code Video Composition
Transmission system, including Intranet, Analysis server, loudspeaker, high definition wire rod, outer net, PC, sound collector, the Analysis Service
Device accesses the Intranet；The Analysis server connects the loudspeaker；The PC accesses the outer net；The PC connections are described
Sound collector；The Analysis server connects the PC by the high definition wire rod.
Further, in the state of Network Isolation, PC high-definition media interface described in outer net safety is in real time
Internally network system unidirectional delivery audio/video flow and two-dimensional code data, Analysis server pass through described high-definition media interface
The audio/video flow passed over is gathered in real time, and extracts two-dimension code image, two-dimension code image relevant information is decoded, to correlation
Information carry out preserve deliver management, finally can by voice message feedback information whether successfully decoded.
Further, the high-definition media interface can be HDMI, DVI interface, DP interfaces and USB interface, can
Realization >=1920*1080 resolution videos transmission is with receiving.
Further, the PC has the high-definition multimedia output interface, and the Analysis server has the high definition
Multimedia input interface.
Further, the PC data of acquisition is made using image in 2 D code generating algorithm recognizable Dynamic Two-dimensional
The form of code, and presented in the desktop images mode of the PC.
Further, the Analysis server has the high-definition multimedia access interface, directly gathers the outer net meter
The audio/video flow of calculation machine desktop images.
Further, described voice message feedback information be the Analysis server by the information after collection analysis not
When complete, re-transmission task can be carried out by PC described in voice informing.
Further, the voice is recognized by the sound collector, and by the PC.
Further, the voice is sent by the loudspeaker connected on the Analysis server.
Further, the outer net is that the PC preserves the data obtained in certain time.
Beneficial effect
（1）Security
