[0015] S1. When connecting a multimedia display to a computer device, it is necessary to turn on the multimedia display verification in advance. The acquisition module starts the verification work. The output end of the acquisition module transmits a signal to the input end of the password module. The operator enters the password. When the password is normal, the password is normal and transmits a signal to the synchronization verification input end. When the password is abnormal, the password is abnormal and transmits a signal to the verification module input end. When the verification is correct, it is normal. It transmits a signal to the acquisition module again, and the operator needs to verify the password again. When the verification is abnormal, it is judged that the external path is connected to the multimedia display, and the establishment fails. The device is prohibited from connecting to protect the multimedia display and prevent it from transmitting private information. Display leakage, when the password module shows that the password is normal, the acquisition module transmits a signal to the input end of the identification module for secondary verification. At this time, the identity of the operator is verified. When the recognition is normal, the verification is successful. The normal recognition and the normal password transmit a signal to the synchronous verification input end. When the verification is successful, the establishment can be triggered successfully, and the computer device can be connected to the multimedia display. When the recognition is abnormal, it is checked through the verification module. When the verification is normal, the identity can be verified again.

Under the troubleshooting of the troubleshooting module, when the troubleshooting is normal, it proves that the computer device and the multimedia display are compatible, and the troubleshooting is normal. The signal is transmitted to the authorization normally. When the troubleshooting exception occurs, it is inconvenient to connect the computer device to the media display. At this time, the acquisition module is not triggered and the connection is rejected.

[0017] S3. When the multimedia display is connected to the computer device, it is necessary to monitor the connection path in real time to prevent the outside world from joining the path and connecting to the multimedia display. Under the monitoring of the monitoring module, when the monitoring is normal, the normal output end of the monitoring transmits a signal to the input end of the monitoring module for real-time monitoring. When the monitoring is abnormal, the abnormal monitoring transmits a signal to the input end of the alarm module to warn the operator that there is an external device connected to the multimedia display.

When the verification is abnormal, it is judged that the external path is connected to the multimedia display, and the establishment fails, and the device is prohibited from connecting to protect the multimedia display. The connection is formed to prevent it from leaking private information. When the password module shows that the password is normal, the acquisition module transmits a signal to the input end of the identification module for a second verification. At this time, the identity of the operator is verified. When the recognition is normal, the verification is successful. The recognition is normal and the password is normal. The signal is transmitted to the synchronous verification input end.

When the password is normal (413), the password is normal (413) transmits a signal to the input end of the synchronization verification (414). When the password is abnormal (416), the password abnormal (416) transmits a signal to the input end of the verification module (417). When the verification is correct, the verification is normal (420), which transmits a signal to the acquisition module (411) again. The operator needs to verify the password again. When the verification is abnormal (418), it is determined that the external path is connected to the multimedia display, and the establishment failure (419) is displayed, and the device is prohibited from connecting to protect the multimedia display to prevent it from leaking private information. When the password module (412) shows that the password is normal (413), the acquisition module (411) transmits a signal to the input end of the identification module (421) to perform a second verification. At this time, the identity of the operator is verified. When the identification is normal (423), the verification is successful. The identification is normal (423) cooperates with the password to transmit a signal to the input end of the synchronization verification (414). When the verification is successful, the establishment success (415) can be triggered, and the computer device can be connected to the multimedia display. When the identification is abnormal (422), the verification is performed through the verification module (417). When the verification is normal (420), the identity can be verified again. When the verification is abnormal (418), the establishment fails (419), and the multimedia display closes the connection. This structure can protect the multimedia display and prevent any device from being connected to it, resulting in leakage of private information display. S2. When it is necessary to connect the computer device to the multimedia display, the multimedia display is verified and turned on, and data is collected through the acquisition module (411). When the authorization is normal (431), it is proved that the computer device and the multimedia display are compatible, and the multimedia display can be turned on. When the authorization is abnormal (432), the authorization abnormal (432) transmits a signal to the input end of the troubleshooting module (433). Under the troubleshooting of the troubleshooting module (433), when the troubleshooting is normal (434), it is proved that the computer device is compatible with the multimedia display. The troubleshooting is normal (434) transmits a signal to the authorization is normal (431). When the troubleshooting is abnormal (435), it is inconvenient to connect the computer device to the multimedia display. At this time, the acquisition module (411) is not triggered and the connection is rejected; S3. When the multimedia display is connected to the computer device, it is necessary to monitor the connection path in real time to prevent the outside world from joining the path and connecting to the multimedia display. Under the monitoring of the monitoring module (441), when the monitoring is normal (442), the output end of the monitoring normal (442) transmits a signal to the input end of the monitoring module (441) for real-time monitoring. When the monitoring is abnormal (443), the monitoring abnormal (443) transmits a signal to the input end of the alarm module (444) to warn the operator that there is an external device connected to the multimedia display. At the same time, the alarm module (444) transmits a signal to the establishment failure (419) to disconnect the multimedia display from the computer device to avoid privacy information leakage.
