[0002] With the popularization of smart phones and smart display devices, the mobile phone screen mirroring function has become an important way for users to share mobile phone content on a large screen. However, most of the existing screen mirroring technologies lack effective security verification mechanisms, resulting in any user who can access the mobile phone screen mirroring function being able to mirror the mobile phone content to an external display device, which increases the risk of information leakage to a certain extent.

[0003] Therefore, how to ensure the security of the screen mirroring process and prevent unauthorized access and leakage is a technical problem that needs to be solved urgently at present. Summary of the Invention

[0012] The display module is used to display the received screen mirroring content.

[0013] Preferably, the server includes a storage module, a verification module, and a sending module;

[0014] Among them, the storage module is used to store the user's biometric template;

[0015] The verification module is used to verify whether the biometric information sent by the mobile client matches the stored biometric template;

[0016] The sending module is used to send the screen mirroring content to the external display device after the verification is passed.

[0017] Preferably, the system further includes a permission management module, which is used to set different screen mirroring permissions for different users;

[0018] The permission management module assigns different screen mirroring permissions to users according to the user's identity, role, or other factors; the screen mirroring permissions include screen mirroring time and screen mirroring content type;

[0019] During the screen mirroring process, the permission management module checks whether the user's screen mirroring request conforms to the corresponding permission settings:

[0028] S2. The mobile client generates a screen mirroring request containing biometric information and the screen mirroring content, and sends the screen mirroring request to the server;

[0029] S3. The server receives the screen mirroring request and verifies whether the biometric information in the screen mirroring request matches the stored biometric template:

[0030] ① If the verification fails, the server rejects the screen mirroring request and returns a verification failure message to the mobile client;

[0031] ② If the verification passes, the server sends the screen mirroring content to the external display device side, and then proceeds to step S5;

[0036] ③ Log recording: Logs of the screen mirroring time, screen mirroring content, and user information during the screen mirroring process are recorded. The log records are stored on the server for traceability and auditing when needed;

[0037] ④ Anomaly detection: Real-time monitoring and early warning of abnormal behaviors during the screen mirroring process; for example, if the server continuously receives screen mirroring requests from the same mobile client but the verification fails, the anomaly detection mechanism is triggered to send a warning message to the administrator; the administrator can take corresponding measures in a timely manner according to the warning message, such as locking the account and investigating the reason, etc.

[0038] Preferably, the working process of the mobile client is as follows:
