Abstract
The invention provides a computer video interference unit. The computer video interference unit comprises a shell and a decryption module arranged in a display, wherein a power interface, a data input interface connected to a host and a data output interface connected to the display are arranged on the shell; a processor, an encryption module, a central control unit and three signal emission modules which are parallel to each other and have different emitted frequencies are arranged in the shell; the encryption module is used for sending data to the central control unit after encryption; the central control unit is connected to the three signal emission modules and is used for randomly sending the encrypted data to the data output interface through one signal emission module; the data output interface is connected to the decryption module; and the power interface is connected to the central control unit. After the computer video interference unit is arranged between the computer host and the display, data which is sent to the display by the computer host is encrypted, so that information leakage caused by electromagnetic leakage is effectively prevented and the security of data transmission is greatly improved.
Description
Technical field
The present invention relates to computer realm, more particularly to a kind of computer video interference unit.
Background technology
Computer mainly has main frame and display to constitute, and main frame is connected with display, realizes data transfer.But,
Main frame occurs different degrees of electromagnetic exposure during transferring data to display unavoidably, and electromagnetic exposure directly can be led
Write breath to be reappeared, in turn result in information leakage, produce serious consequence.Therefore, how to prevent from causing letter due to electromagnetic exposure
It is a problem in the urgent need to address at present that breath leaks.
The content of the invention
The defect of prior art and various weak points in view of the above, the technical problem to be solved in the present invention is to carry
For a kind of computer video interference unit, which can effectively prevent causing information leakage due to electromagnetic exposure.
For achieving the above object, the present invention provides a kind of computer video interference unit, is connected to the main frame of computer and shows
Show between device, the computer video interference unit includes housing and installation deciphering module in the display, sets on the housing
There are Data Input Interface and the data output interface being connected with display that power interface is connected with main frame, the number
USB interface is according to input interface and data output interface, be provided with the housing processor, encrypting module, central controller,
And three be mutually juxtaposed and the signal emission module with different emitted frequencies, the Data Input Interface, processor, plus
Close module and central controller are sequentially connected, and the encrypting module is for central controller will be sent to after data encryption, described
Central controller is connected with three signal emission module, for by the data after encryption at random by a signal emission module
Data output interface is sent to, the data output interface is connected with deciphering module, the power interface and central controller
It is connected.
Computer video interference unit according to the present invention has the advantages that：
After the present invention is arranged between main frame and display, the data that main frame is sent to display are entered
Row encryption, so as to effectively prevent causing information leakage due to electromagnetic exposure, greatly improves the safety of data transfer.

Specific embodiment
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail.
As shown in figure 1, the application provides a kind of computer video interference unit, the main frame 1 and display 2 of computer are connected to
Between, the computer video interference unit includes housing 3 and the deciphering module 4 in display 2, sets on the housing 3
The Data Input Interface 6 that has power interface 5, be connected with main frame 1, and the data output interface 7 that is connected with display 2,
The Data Input Interface 6 and data output interface 7 are USB interface, be provided with the housing 3 processor 8, encrypting module 9,
Central controller 10, and three be mutually juxtaposed and the signal emission module 11 with different emitted frequencies, the data are defeated
Incoming interface 6, processor 8, encrypting module 9 and central controller 10 are sequentially connected, and the encrypting module 9 is for by after data encryption
It is sent to central controller 10, the central controller 10 is connected with three signal emission module 11, for by after encryption
Data are sent to data output interface 7, the data output interface 7 and deciphering module by a signal emission module 11 at random
4 are connected, and the power interface 5 is connected with central controller 10, are that computer video interference unit is powered.
After above computer video interference unit is connected between the main frame 1 of computer and display 2, the master of computer
Data are sent to computer video interference unit by Data Input Interface 6 by machine 1, then processor 8 is to being sent to after data processing
Encrypting module 9 is encrypted, and is sent to data output interface 7 by a signal emission module 11 at random again afterwards, number
According to output interface 7 again by the data is activation after encryption to display 2, and be sent in display 2 after being decrypted by deciphering module 4
Controller, so as to the content expressed by data is correspondingly shown.As main frame 1 is sent to display by the present invention
The data of device 2 are encrypted, and so as to effectively prevent causing information leakage due to electromagnetic exposure, greatly improve the peace of data transfer
Quan Xing.
In sum, the present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
