Signal interaction method and system based on double-network mode

Abstract

The invention discloses a signal interaction method and system based on a double-network mode. The system comprises an intranet computer, a first relay, a second relay, a public network computer, a video switcher and a displayer, wherein the intranet computer is used for processing data service and feeding back the data service in an intranet mode and sending a first control instruction; the firstrelay can generate a public network activation signal and a first video switching request signal and activate the intranet computer; the second relay can activate the public network computer and generate an intranet feedback signal and a second video switching request signal; the public network computer can process the data service, which is processed in the intranet mode, in a public network mode and send a second control instruction to the second relay after processing the data service in the public network mode; and the video switcher realizes switching between an intranet display interface and a public network display interface. Through the signal interaction method and system, information interaction between an intranet and a public network can be realized on the premise of guaranteeing the security of intranet service, and information processing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a method and system for signal interaction based on a dual network mode. Background technique [0002] At present, intranet and public network are two network modes commonly used in computers. The public network (public network) mode is not suitable for those departments or units that require high information security, because the public network mode can easily lead to information leakage or attack. Therefore, in order to ensure information security, the current usual method is to do business processes on the intranet handle. For example, when the payment item is processed, go to the payment window or the bank to pay the fee, and then come back to go through the rest of the process after the payment is completed; although the connection mode with the bank's private network guarantees relative security of information, it can meet the general high requirements ...

Problems solved by technology

For example, when the payment item is processed, go to the payment window or the bank to pay the fee, and then come back to handle the rest of the process after the payment is completed; although the connection mode with the bank's private network guarantees relative security of information, it can meet information security requirements. Generally high However, it is not suitable for those departments that have high requirements for information security, and the connection with the bank's private network needs to be approved layer by layer. After the approval is completed, the bank needs to open a special interface, which is not only cumbersome and costly. , and low efficiency

A single use of the public network will reduce the security performance of the network
